basically I am creating a Task/ToDo List app and I can't figure this part out. I want to add a checkbox next to each task and the ability to check them.
Here is the MainActivity.java
public class MainActivity extends AppCompatActivity {
static ArrayList<String> notes = new ArrayList<>();
static ArrayAdapter arrayAdapter;
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.main_menu, menu);
return super.onCreateOptionsMenu(menu);
}
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
if (item.getItemId() == R.id.add_note) {
Intent intent = new Intent(getApplicationContext(),
note_editor.class);
startActivity(intent);
return true;
}
return false;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView = (ListView) findViewById(R.id.listView);
SharedPreferences sharedPreferences =
getApplicationContext().getSharedPreferences
("com.example.assignment1", Context.MODE_PRIVATE);
HashSet<String> set = (HashSet<String>)
sharedPreferences.getStringSet("notes", null);
if (set == null) {
notes.add("Add Your Task Hereee");
} else {
notes = new ArrayList(set);
}
arrayAdapter = new ArrayAdapter
(this, android.R.layout.simple_list_item_1, notes);
listView.setAdapter(arrayAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick
(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent = new Intent(getApplicationContext(),
note_editor.class);
intent.putExtra("noteId", i);
startActivity(intent);
}
});
My main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:id="#+id/listView" />
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:layout_marginEnd="32dp"
android:layout_marginBottom="28dp"
android:backgroundTint="#4BB3A9"
android:src="#drawable/add_task"/>
</RelativeLayout>
I want it to look something like this":
I drew the checkboxes here
I also have another class for when editing the tasks as well as for a splash screen but I don't think it's necessary here. Any help would be really appreciated!
You could use Recycler view instead of List view. See below code for Reference:
Create custom adapter and set it to your Recycler view and call it like recyclerView.setAdapter(CustomAdapter(new ArrayList("AAAAA","BBBBB","CCCCC","DDDDD"),getContext()));
Custom Adapter
public class CustomAdapter extends ArrayAdapter<String> {
private ArrayList<String> dataSet;
// View lookup cache
private static class ViewHolder {
CheckedTextView checkedTextView;
}
public CustomAdapter(ArrayList<String> data, Context context) {
super(context, R.layout.list_item, data);
this.dataSet = data;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Check if an existing view is being reused, otherwise inflate the view
ViewHolder viewHolder; // view lookup cache stored in tag
if (convertView == null) {
viewHolder = new ViewHolder();
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView = inflater.inflate(R.layout.list_item, parent, false);
viewHolder.checkedTextView = convertView.findViewById(R.id.check_box);
viewHolder.checkedTextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
viewHolder.checkedTextView.setChecked(!viewHolder.checkedTextView.isChecked());
}
});
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.checkedTextView.setText(dataSet.get(position));
return convertView;
}
}
XML code for each list item : list_item.xml
<CheckedTextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/check_box"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="10dp"
android:layout_marginEnd="10dp"
android:checked="false"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:gravity="center"
android:text="Check Me"
/>
You are using an android default layout for your ListView and this default layout shows a TextView only, you have to create custom layout for your list item views and custom ArrayAdapter to achieve what you want.
for more information check out this:https://javapapers.com/android/android-listview-custom-layout-tutorial/
As a tip switch for RecyclerView which is much more efficient: https://developer.android.com/guide/topics/ui/layout/recyclerview
I want to create a custom adapter for my list view. Is there any article that can walk me through how to create one and also explain how it works?
public class ListAdapter extends ArrayAdapter<Item> {
private int resourceLayout;
private Context mContext;
public ListAdapter(Context context, int resource, List<Item> items) {
super(context, resource, items);
this.resourceLayout = resource;
this.mContext = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(mContext);
v = vi.inflate(resourceLayout, null);
}
Item p = getItem(position);
if (p != null) {
TextView tt1 = (TextView) v.findViewById(R.id.id);
TextView tt2 = (TextView) v.findViewById(R.id.categoryId);
TextView tt3 = (TextView) v.findViewById(R.id.description);
if (tt1 != null) {
tt1.setText(p.getId());
}
if (tt2 != null) {
tt2.setText(p.getCategory().getId());
}
if (tt3 != null) {
tt3.setText(p.getDescription());
}
}
return v;
}
}
This is a class I had used for my project. You need to have a collection of your items which you want to display, in my case it's <Item>. You need to override View getView(int position, View convertView, ViewGroup parent) method.
R.layout.itemlistrow defines the row of the ListView.
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content" android:orientation="vertical"
android:layout_width="fill_parent">
<TableRow android:layout_width="fill_parent"
android:id="#+id/TableRow01"
android:layout_height="wrap_content">
<TextView android:textColor="#FFFFFF"
android:id="#+id/id"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="id" android:textStyle="bold"
android:gravity="left"
android:layout_weight="1"
android:typeface="monospace"
android:height="40sp" />
</TableRow>
<TableRow android:layout_height="wrap_content"
android:layout_width="fill_parent">
<TextView android:textColor="#FFFFFF"
android:id="#+id/categoryId"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="categoryId"
android:layout_weight="1"
android:height="20sp" />
<TextView android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:textColor="#FFFFFF"
android:gravity="right"
android:id="#+id/description"
android:text="description"
android:height="20sp" />
</TableRow>
</TableLayout>
In the MainActivity define ListViewlike this,
ListView yourListView = (ListView) findViewById(R.id.itemListView);
// get data from the table by the ListAdapter
ListAdapter customAdapter = new ListAdapter(this, R.layout.itemlistrow, List<yourItem>);
yourListView .setAdapter(customAdapter);
I know this has already been answered... but I wanted to give a more complete example.
In my example, the ListActivity that will display our custom ListView is called OptionsActivity, because in my project this Activity is going to display the different options my user can set to control my app. There are two list item types, one list item type just has a TextView and the second list item type just has a Button. You can put any widgets you like inside each list item type, but I kept this example simple.
The getItemView() method checks to see which list items should be type 1 or type 2. According to my static ints I defined up top, the first 5 list items will be list item type 1, and the last 5 list items will be list item type 2. So if you compile and run this, you will have a ListView that has five items that just contain a Button, and then five items that just contain a TextView.
Below is the Activity code, the activity xml file, and an xml file for each list item type.
OptionsActivity.java:
public class OptionsActivity extends ListActivity {
private static final int LIST_ITEM_TYPE_1 = 0;
private static final int LIST_ITEM_TYPE_2 = 1;
private static final int LIST_ITEM_TYPE_COUNT = 2;
private static final int LIST_ITEM_COUNT = 10;
// The first five list items will be list item type 1
// and the last five will be list item type 2
private static final int LIST_ITEM_TYPE_1_COUNT = 5;
private MyCustomAdapter mAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mAdapter = new MyCustomAdapter();
for (int i = 0; i < LIST_ITEM_COUNT; i++) {
if (i < LIST_ITEM_TYPE_1_COUNT)
mAdapter.addItem("item type 1");
else
mAdapter.addItem("item type 2");
}
setListAdapter(mAdapter);
}
private class MyCustomAdapter extends BaseAdapter {
private ArrayList<String> mData = new ArrayList<String>();
private LayoutInflater mInflater;
public MyCustomAdapter() {
mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(final String item) {
mData.add(item);
notifyDataSetChanged();
}
#Override

if(position < LIST_ITEM_TYPE_1_COUNT)
return LIST_ITEM_TYPE_1;
else
return LIST_ITEM_TYPE_2;
}

return LIST_ITEM_TYPE_COUNT;
}

Google has an example called EfficientAdapter, which in my opinion is the best simple example of how to implement custom adapters. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html
#CommonsWare has written a good explanation of the patterns used in the above example
http://commonsware.com/Android/excerpt.pdf
check this link, in very simple via the convertView, we can get the layout of a row which will be displayed in listview (which is the parentView).
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.itemlistrow, null);
}
using the position, you can get the objects of the List<Item>.
Item p = items.get(position);
after that we'll have to set the desired details of the object to the identified form widgets.
if (p != null) {
TextView tt = (TextView) v.findViewById(R.id.id);
TextView tt1 = (TextView) v.findViewById(R.id.categoryId);
TextView tt3 = (TextView) v.findViewById(R.id.description);
if (tt != null) {
tt.setText(p.getId());
}
if (tt1 != null) {
tt1.setText(p.getCategory().getId());
}
if (tt3 != null) {
tt3.setText(p.getDescription());
}
}
then it will return the constructed view which will be attached to the parentView (which is a ListView/GridView).
Data Model
public class DataModel {
String name;
String type;
String version_number;
String feature;
public DataModel(String name, String type, String version_number, String feature ) {
this.name=name;
this.type=type;
this.version_number=version_number;
this.feature=feature;
}
public String getName() {

You can take a look at this sample in the official ApiDemos. It shows how to extend BaseAdapter and apply it to a ListView. After that, just look at the reference for BaseAdapter and try to understand what each method does (including the inherited ones) and when/how to use it.
Also, Google is your friend :).
Here is the complete walk through to create a custom adapter for list view step by step -
https://www.caveofprogramming.com/guest-posts/custom-listview-with-imageview-and-textview-in-android.html
public class CustomAdapter extends BaseAdapter{
String [] result;
Context context;
int [] imageId;
private static LayoutInflater inflater=null;
public CustomAdapter(MainActivity mainActivity, String[] prgmNameList, int[] prgmImages) {
// TODO Auto-generated constructor stub
result=prgmNameList;
context=mainActivity;
imageId=prgmImages;
inflater = ( LayoutInflater )context.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return result.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public class Holder
{
TextView tv;
ImageView img;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.program_list, null);
holder.tv=(TextView) rowView.findViewById(R.id.textView1);
holder.img=(ImageView) rowView.findViewById(R.id.imageView1);
holder.tv.setText(result[position]);
holder.img.setImageResource(imageId[position]);
rowView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
}
});
return rowView;
}
}
A more compact example of a custom adapter (using list array as my data):
class MyAdapter extends ArrayAdapter<Object> {
public ArrayAdapter(Context context, List<MyObject> objectList) {
super(context, R.layout.my_list_item, R.id.textViewTitle, objectList.toArray());
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = super.getView(position, convertView, parent);
TextView title = (TextView) row.findViewById(R.id.textViewTitle);
ImageView icon = (ImageView) row.findViewById(R.id.imageViewAccessory);
MyObject obj = (MyObject) getItem(position);
icon.setImageBitmap( ... );
title.setText(obj.name);
return row;
}
}
And this is how to use it:
List<MyObject> objectList = ...
MyAdapter adapter = new MyAdapter(this.getActivity(), objectList);
listView.setAdapter(adapter);
BaseAdapter is best custom adapter for listview.
Class MyAdapter extends BaseAdapter{}
and it has many functions such as getCount(), getView() etc.
It is very simple.

I'm very new to android and I was given a prewritten app that I must improve. One thing I have to do is add a delete button to each item in a ListView.
Here is the XML for my ListView element:
LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:descendantFocusability="blocksDescendants"
android:orientation="horizontal" >
<ImageView
android:id="#+id/li_map_image"
android:layout_width="50dp"
android:layout_height="match_parent"
android:contentDescription="thumbnail" />
<TextView
android:id="#+id/li_map_name"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:paddingLeft="8dp"
android:textSize="16sp" />
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/delete"
android:focusableInTouchMode="true"
android:background="#drawable/red_x"
android:layout_gravity="center|left"
android:onClick="deleteMap"></ImageButton>
Basically, I want the user to click the delete icon if they want to delete a row in the ListView. Also, this should delete the item's data from the database. I'm very confused about how to implement this because I don't know how I will know which delete button they are clicking. Also, when I added the ImageButton to the ListView code, it tells me to make the onClick method in main (should it be in main?); but how will I be able to delete data from the database? Also, Main Activity has a Fragment which obtains the ListView code. This is the Fragment class:
public class MapListFragment extends ListFragment implements
LoaderManager.LoaderCallbacks<Cursor> {
private static final int LOADER_ID = 1;
private static final String[] FROM = { Database.Maps.DATA,
Database.Maps.NAME };
private static final String[] CURSOR_COLUMNS = { Database.Maps.ID,
Database.Maps.DATA, Database.Maps.NAME };
private static final int[] TO = { R.id.li_map_image, R.id.li_map_name };
private SimpleCursorAdapter mAdapter;
// FIXME isn't this unnecessary?
public MapListFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// FIXME reverse the order so the newest sessions are at the top
mAdapter = new SimpleCursorAdapter(getActivity(),
R.layout.map_list_item, null, FROM, TO, 0);
mAdapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
#Override
public boolean setViewValue(View view, Cursor cursor,
int columnIndex) {
if (view.getId() == R.id.li_map_image) {
((ImageView) view).setImageURI(Uri.parse(cursor
.getString(columnIndex)));
return true;
}
return false;
}
});
setListAdapter(mAdapter);
getLoaderManager().initLoader(LOADER_ID, null, this);
}
#Override
public void onListItemClick(ListView list, View v, int position, long id) {
final Intent nextIntent = new Intent(getActivity(),
ViewMapActivity.class);
nextIntent.putExtra(Utils.Constants.MAP_ID_EXTRA, id);
startActivity(nextIntent);
}
#Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
return new CursorLoader(getActivity(), DataProvider.MAPS_URI,
CURSOR_COLUMNS, null, null, null);
}
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
if (loader.getId() == LOADER_ID)
mAdapter.swapCursor(cursor);
}
#Override
public void onLoaderReset(Loader<Cursor> loader) {
mAdapter.swapCursor(null);
}
}
I'm very lost as how to implement this delete feature. Any help will be much appreciated :)
here is a very good tutorial on how to put a clicklistener on a button inside listview.
follow this link
inside your adapter getView method, you need to put click listener on button like this
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(context);
convertView = inflater.inflate(R.layout.child_listview, null);
viewHolder = new ViewHolder();
viewHolder.text = (TextView) convertView
.findViewById(R.id.childTextView);
viewHolder.button = (Button) convertView
.findViewById(R.id.childButton);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
final String temp = getItem(position);
viewHolder.text.setText(temp);
viewHolder.button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (customListner != null) {
customListner.onButtonClickListner(position,temp);
}
}
});
return convertView;
}

I have a list view with that I have set up with 2 textview inside of it, on is on the right and one is on the left, and I want to set an onClickListerner for them and get the text of the one that was clicked, and also the row of the list view that was clicked.
I have been able to set up to get the row that was clicked but now I need help finding out which textview in the row was clicked.
Here is my set up for the cell in the list view:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="text1"
android:id="#+id/1"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:textColor="#ffffffff" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="text2"
android:id="#+id/2"
android:minHeight="60dp"
android:textSize="18dp"
android:gravity="center"
/>
</RelativeLayout>
Here is my MainActivity.java with the set up list view and what I have tried so far.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
populateCarList();
populateListView();
registerClickCallback();
private void populateCarList() {
userDiningHall.add(new DiningHall("hall1", open1));
userDiningHall.add(new DiningHall("hall2", open2));
userDiningHall.add(new DiningHall("hall3", open3));
userDiningHall.add(new DiningHall("hall4", open4));
}
private void populateListView() {
ArrayAdapter<DiningHall> adapter = new MyListAdapter();
ListView list = (ListView)findViewById(R.id.homeListView);
list.setAdapter(adapter);
}
//THIS GETS WHAT ROW WAS CLICKED
private void registerClickCallback() {
ListView list = (ListView)findViewById(R.id.homeListView);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent,View ViewClicked, int position, long id) {
DiningHall clickedDiningHall = userDiningHall.get(position);
String message = "You clicked position " + position + " which is dining hall " +
clickedDiningHall.getDiningHallName();
Toast.makeText(MainActivity.this, message, Toast.LENGTH_LONG).show();
}
});
}
private class MyListAdapter extends ArrayAdapter<DiningHall> {
public MyListAdapter() {
super(MainActivity.this, R.layout.home_item_view, userDiningHall);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = convertView;
if (itemView == null) {
itemView = getLayoutInflater().inflate(R.layout.home_item_view, parent, false);
}
//Find the dining hall
DiningHall currentDiningHall = userDiningHall.get(position);
//Fill the view
TextView diningHallText = (TextView)itemView.findViewById(R.id.itemDiningHallTextView);
diningHallText.setText(currentDiningHall.getDiningHallName());
TextView openText = (TextView)itemView.findViewById(R.id.itemOpenTextView);
openText.setText(currentDiningHall.getDiningHallOpen());
return itemView;
}
}
How can I get what row was clicked and what textview was clicked?
Thanks for the help in advance. :)
You can set the same View.OnClickListener for both TextViews. Then simply check the id of the clicked View in onClick(View v) by calling v.getId().
you can set simply setOnclickListner for both TextViews and also set OnItemclickLister in listview
I'm trying to make a task manager, and I only have one problem. I have a listview that gets inflated. All the elements in the listview are correct. The problem is that when I select an item, the listview will select another item away. I've heard listviews repopulate the list as it scrolls down to save memory. I think this may be some sort of problem. Here is a picture of the problem.
If i had more apps loaded, then it would continue to select multiple at once.
Here is the code of my adapter and activity and XML associated
public class TaskAdapter extends BaseAdapter{
private Context mContext;
private List<TaskInfo> mListAppInfo;
private PackageManager mPack;
public TaskAdapter(Context c, List<TaskInfo> list, PackageManager pack) {
mContext = c;
mListAppInfo = list;
mPack = pack;
}
#Override
public int getCount() {
return mListAppInfo.size();
}
#Override
public Object getItem(int position) {
return mListAppInfo.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
TaskInfo entry = mListAppInfo.get(position);
if (convertView == null)
{
LayoutInflater inflater = LayoutInflater.from(mContext);
//System.out.println("Setting LayoutInflater in TaskAdapter " +mContext +" " +R.layout.taskinfo +" " +R.id.tmbox);
convertView = inflater.inflate(R.layout.taskinfo,null);
}
ImageView ivIcon = (ImageView)convertView.findViewById(R.id.tmImage);
ivIcon.setImageDrawable(entry.getIcon());
TextView tvName = (TextView)convertView.findViewById(R.id.tmbox);
tvName.setText(entry.getName());
convertView.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v) {
final CheckBox checkBox = (CheckBox)v.findViewById(R.id.tmbox);
if(v.isSelected())
{
System.out.println("Listview not selected ");
//CK.get(arg2).setChecked(false);
checkBox.setChecked(false);
v.setSelected(false);
}
else
{
System.out.println("Listview selected ");
//CK.get(arg2).setChecked(true);
checkBox.setChecked(true);
v.setSelected(true);

Any ideas for what reason mutliple items are selected with a single click would be GREATLY appreciated. I've been messing around with different implementations and listeners and listadapters but to no avail.
I think the point is you only save checking state in the view(v.setSelected).
And you reuse these view, so its checkbox is always not change its state.
You can create a state array to save every checking state of every TaskInfo, and check this array when you create a view.
for example
// default is false
ArrayList<Boolean> checkingStates = new ArrayList<Boolean>(mListAppInfo.size());
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
TaskInfo entry = mListAppInfo.get(position);
if (convertView == null)
{
LayoutInflater inflater = LayoutInflater.from(mContext);
convertView = inflater.inflate(R.layout.taskinfo,null);
}
ImageView ivIcon = (ImageView)convertView.findViewById(R.id.tmImage);
ivIcon.setImageDrawable(entry.getIcon());
TextView tvName = (TextView)convertView.findViewById(R.id.tmbox);
tvName.setText(entry.getName());
final CheckBox checkBox = (CheckBox)v.findViewById(R.id.tmbox);
checkBox.setChecked(checkingStates.get(position));
convertView.setSelected(checkingStates.get(position));
convertView.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v) {
if(v.isSelected())
{
System.out.println("Listview not selected ");
//CK.get(arg2).setChecked(false);
checkBox.setChecked(false);
v.setSelected(false);
checkingStates.get(position) = false;
}
else
{
System.out.println("Listview selected ");
//CK.get(arg2).setChecked(true);
checkBox.setChecked(true);
v.setSelected(true);
checkingStates.get(position) = true;
}
}
});
return convertView;
}
I'm not 100% sure what you are trying to do, but part of your problem might be related to the condition in your onClick method:
if(v.isSelected())
I think you want that to read
if(v.isChecked())
isSelected is inherited from View, and it means something different from isChecked
Also, the whether the CheckBox is checked or not is independent from your data model since it is a recycled view. Your CheckBox should be checked based on entry (I'm assuming your TextInfo class has an isChecked() method that returns a boolean:
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
TaskInfo entry = mListAppInfo.get(position);
if (convertView == null)
{
LayoutInflater inflater = LayoutInflater.from(mContext);
//System.out.println("Setting LayoutInflater in TaskAdapter " +mContext +" " +R.layout.taskinfo +" " +R.id.tmbox);
convertView = inflater.inflate(R.layout.taskinfo,null);
}
ImageView ivIcon = (ImageView)convertView.findViewById(R.id.tmImage);
ivIcon.setImageDrawable(entry.getIcon());
TextView tvName = (TextView)convertView.findViewById(R.id.tmbox);
tvName.setText(entry.getName());
CheckBox checkBox = (CheckBox)v.findViewById(R.id.tmbox);
checkBox.setChecked(entry.isChecked());
}
I don't think you need the View.OnClickListener you are attaching to convertView. You should handle that in the OnItemClickListener attached to the ListView. Assuming your ListView is called listView and TaskInfo instances have setChecked and isChecked methods:
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
entry = mListAppInfo.get(position);
entry.setChecked(!entry.isChecked());
}
});
First of all don't set the list checked or unchecked on view position.
because view position means only visible items position in your listview but you would like to set checked or uncheked status on a particular list item.
That's why this problem arises in your code.
You have the need to set the items checked and unchecked on your custom arraylist getter setter like the code i have attached below:
package com.app.adapter;
public class CategoryDynamicAdapter {
public static ArrayList<CategoryBean> categoryList = new ArrayList<CategoryBean>();
Context context;
Typeface typeface;
public static String videoUrl = "" ;
Handler handler;
Runnable runnable;
// constructor
public CategoryDynamicAdapter(Activity a, Context context, Bitmap [] imagelist,ArrayList<CategoryBean> list) {
this.context = context;
this.categoryList = list;
this.a = a;
}
// Baseadapter to the set the data response from web service into listview.
public BaseAdapter mEventAdapter = new BaseAdapter() {
#Override
public int getCount() {
return categoryList.size();
}
#Override
public Object getItem(int position) {
return categoryList.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
class ViewHolder {
TextView title,category,uploadedBy;
ImageView image;
RatingBar video_rating;
Button report_video ,Flag_video;
}
public View getView(final int position, View convertView, final ViewGroup parent) {
ViewHolder vh = null ;
if(convertView == null) {
vh = new ViewHolder();
convertView = LayoutInflater.from(context).inflate (R .layout.custom_category_list_layout,null,false);
vh.title = (TextView) convertView .findViewById (R.id.title);
vh.image = (ImageView) convertView.findViewById(R.id.Imagefield);
convertView.setTag(vh);
}
else
{
vh=(ViewHolder) convertView.getTag();
}
try
{
final CategoryBean Cb = categoryList.get(position);
//pay attention to code below this line i have shown here how to select a listview using arraylist getter setter objects
String checkedStatus = Cb.getCheckedStringStaus();
if(checkdStatus.equal("0")
{
System.out.println("Listview not selected ");
//CK.get(arg2).setChecked(false);
checkBox.setChecked(false);
v.setSelected(false);
}
else ////checkdStatus.equal("1")
{
System.out.println("Listview selected ");
//CK.get(arg2).setChecked(true);
checkBox.setChecked(true);
v.setSelected(true);
}
catch (Exception e)
{
e.printStackTrace();
}
