How to use Radiogroup with 4 different Radio Button In ArrayAdapter

I have a custom List Adapter that has a question in a Text View and four options as an answer in Radio Buttons. All the Radio Buttons are bound together in a Radio Group.
The problem is that I cannot keep track of the buttons that are checked.On scrolling the buttons get checked on random.
How can I store the radio buttons that are checked for a particular
public class MCQAdapter extends ArrayAdapter {
public MCQAdapter(Activity context, ArrayList<MCQ> mcq) {
super(context, 0, mcq);
}
#NonNull
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View listItemView = convertView;
if (listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.activity_mcqlist, parent, false);
}
final MCQ currentContent = (MCQ) getItem(position);
TextView content = (TextView) listItemView.findViewById(R.id.Question_Block);
content.setText(currentContent.getQuestion());
RadioGroup rg = (RadioGroup) listItemView.findViewById(R.id.Radio_Group);
final RadioButton rb1 = (RadioButton) listItemView.findViewById(R.id.Option1_Block);
rb1.setText(currentContent.getOptionA());
final RadioButton rb2 = (RadioButton) listItemView.findViewById(R.id.Option2_Block);
rb2.setText(currentContent.getOptionB());
final RadioButton rb3 = (RadioButton) listItemView.findViewById(R.id.Option3_Block);
rb3.setText(currentContent.getOptionC());
final RadioButton rb4 = (RadioButton) listItemView.findViewById(R.id.Option4_Block);
rb4.setText(currentContent.getOptionD());
return listItemView;
}
}

You should create a wrapper around your PoJo class (MCQ), name it ViewModel, which store the current state of view inside adapter. In your case that state is a state of radio buttons.
It will looks like:
class ViewModel extends MCQ {
MCQ mcq;
int radioButtonSelectedId;
public ViewModel(MCQ mcq) {
this.mcq = mcq;
this.radioButtonSelectedId = R.id.Option1_Block;
}
public void setRadioButtonSelectedId(int id) {
this.id = id;
}
public int getRadioButtonSelectedId() {
return id;
}
//delegates to mcq getter/setter methods
}
Your getView method:
public View getView(int position, View convertView, ViewGroup parent) {
//your logic above
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
viewModel.setRadioButtonSelectedId(checkedId);
}
});
//same for other radio buttons
rb1.setChecked(viewModel.getRadioButtonSelectedId() == R.id.Option1_Block);
//your logic below
}
So as i mention above, your array list inside adapter would contain ViewModels wrappers, not MCQ classes directly
final ArrayList<ViewModel> mcqList = new ArrayList<>();
MCQ mcq = new MCQ("The property of material by which it can be beaten or rolled into thin plates, is called ?",
"Malleability","Ductility","Plasticity","Elasticity","Malleability")
mcqList.add(new ViewModel(mcq));
I think you should get an option

I want to display two items in one row in listview

I wanted to show 2 items on a single row in textfield,How can I place 2 items in the same row in listview?
I want something like this to be displayed :
item 1
item 2|item3
item 4
item 5 | item 6
My code :

ListView doesn't really support this kind of operation. Items in a ListView must be stacked vertically. And the inner implementation of ListView will prevent any simple attempt to convince it to lay items out differently.
Check out the GridLayout control in the compatibility library. That covers what you want to do fairly easily.

For displaying two items in one row, you must use LinearLayout as parent with weight 1. Orientation of linear layout must be horizontal.
add two childs with weight 0.5 inside the linear layout.
Definitely not the only way to do it but it will do what you ask for.
Hope it helps.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="1" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="text" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="text" />
</LinearLayout>

Unable to listen to setOnItemClickListener in ListView - Android

I have a ListView in my MainActivity which has a customAdapter to it. I am implementing a slider on each of the list items. I have also attached a footerView to my listView. Now my problem is that, the setOnClickListener is not fired, and I am not able to print the position's of the listView. It only print's for the footerView alone, which I have attached.
The code for MainActivity is
public class MainActivity extends Activity {
private static final String TAG = "MainActivity";
private Context mContext;
private ListView mainListView;
private TextView addContact;
private EditText inputName;
private List<String> contactList = new ArrayList<String>();
private MainListAdapter mainAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
mContext = this;
init();
}
private void init() {
mainListView = (ListView)findViewById(R.id.lv_main);
initListData();
View footerView = getLayoutInflater().inflate(R.layout.listview_item_main, null);
footerView.setBackgroundColor(getResources().getColor(R.color.gold));
addContact = (TextView)footerView.findViewById(R.id.tv_item_name);
addContact.setText(getString(R.string.plus));
mainListView.addFooterView(footerView);
mainAdapter = new MainListAdapter(mContext, contactList);
mainListView.setAdapter(mainAdapter);
mainListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e(TAG, "on click item " + position);
if (position == contactList.size()) {
addContact.setVisibility(View.GONE);
inputName.setVisibility(View.VISIBLE);
}
}
});
inputName = (EditText)footerView.findViewById(R.id.et_input_name);
inputName.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE || actionId == EditorInfo.IME_ACTION_GO) {
InputMethodManager imm = (InputMethodManager)mContext
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isActive()) {
imm.hideSoftInputFromWindow(v.getApplicationWindowToken(), 0);
}
String strInput = inputName.getText().toString();
contactList.add(strInput);
addContact.setVisibility(View.VISIBLE);
inputName.getText().clear();
inputName.setVisibility(View.GONE);
}
return false;
}
});
}
private void initListData() {
// temp data
contactList.add("Jacob");
contactList.add("Nicolas");
contactList.add("David");
contactList.add("Jacob");
contactList.add("Nicolas");
contactList.add("David");
}
}
Then the code for my CustomAdapter is

}
private void deleteContact(int postion) {
mList.remove(postion);
}
}

Please help me to listen to the onItemClickListener in the MainActivity's list. I am not able to figure out where I went wrong. Thanks in advance.

you have to put your "setOnItemClickListener" to your Adapter class insted of MainActivity.

public View getView(final int position, View convertView, ViewGroup parent) {
// Declare Variables
ViewHolder holder;
View iView = convertView;
if (convertView == null) {
iView = inflater.inflate(R.layout.listview_item, parent, false);
holder = new ViewHolder();
holder.txt_name = (TextView) iView.findViewById(R.id.name);
Typeface custom_fontG = Typeface.createFromAsset(
context.getAssets(), "KozGoPr6N-Regular.otf");
holder.txt_name.setTypeface(custom_fontG);
holder.txt_desc = (TextView) iView.findViewById(R.id.detail);
holder.ivProfile = (ImageView) iView.findViewById(R.id.flag);
iView.setTag(holder);
} else {
holder = (ViewHolder) iView.getTag();
}
// Get the position
resultp = data.get(position);
// Locate the TextViews in listview_item.xml
// Capture position and set results to the TextViews
holder.txt_name.setText(resultp.get(OurTeam.TAG_NAME));
holder.txt_desc.setText(resultp.get(OurTeam.TAG_DETAIL));
imageLoader.displayImage(TAG_IMAGEURL + resultp.get((OurTeam.TAG_IMG)),
holder.ivProfile, options);
// Capture ListView item click
iView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// Get the position
// your code
}
});
return iView;
}

At a time you can handle click event either in Adapter class of in Activity. in your case you are doing both.
And to manage
addContact.setVisibility(View.GONE);
inputName.setVisibility(View.VISIBLE);
Write above on click event of what ever is main view in listview_item layout (Do not forget to pass addContact and inputName views to your CustomAdapter).

public class MainActivity extends Activity {
private static final String TAG = "MainActivity";
private Context mContext;
private ListView mainListView;
private TextView addContact;
private EditText inputName;
private List<String> contactList = new ArrayList<String>();
private MainListAdapter mainAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
mContext = this;
init();
}
private void init() {
mainListView = (ListView)findViewById(R.id.lv_main);
initListData();
View footerView = getLayoutInflater().inflate(R.layout.listview_item_main, null);
footerView.setBackgroundColor(getResources().getColor(R.color.gold));
addContact = (TextView)footerView.findViewById(R.id.tv_item_name);
addContact.setText(getString(R.string.plus));
mainListView.addFooterView(footerView);
mainAdapter = new MainListAdapter(mContext, contactList);
mainListView.setAdapter(mainAdapter);
/* mainListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e(TAG, "on click item " + position);
if (position == contactList.size()) {
addContact.setVisibility(View.GONE);
inputName.setVisibility(View.VISIBLE);
}
}
});*/
inputName = (EditText)footerView.findViewById(R.id.et_input_name);
inputName.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE || actionId == EditorInfo.IME_ACTION_GO) {
InputMethodManager imm = (InputMethodManager)mContext
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isActive()) {
imm.hideSoftInputFromWindow(v.getApplicationWindowToken(), 0);
}
String strInput = inputName.getText().toString();
contactList.add(strInput);
addContact.setVisibility(View.VISIBLE);
inputName.getText().clear();
inputName.setVisibility(View.GONE);
}
return false;
}
});
}
private void initListData() {
// temp data
contactList.add("Jacob");
contactList.add("Nicolas");
contactList.add("David");
contactList.add("Jacob");
contactList.add("Nicolas");
contactList.add("David");
}
}

add this below line in your listview_item parent layout only.
android:descendantFocusability="blocksDescendants"
actually when the list item contains a element which can get focus then list item click listener not work.

Add this to the parent of your Listview and parent of your listview_item and try again:
android:descendantFocusability="blocksDescendants"
Like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:descendantFocusability="blocksDescendants"
android:layout_height="match_parent"
android:background="#color/background"
tools:context="${packageName}.${activityClass}" >
<ListView
android:id="#+id/lv_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:cacheColorHint="#android:color/transparent"
android:listSelector="#android:color/transparent" />
and this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:descendantFocusability="blocksDescendants"
android:minHeight="100dp" >
<com.example.yo.view.MyViewPager
android:id="#+id/vp_list_item"
android:layout_width="fill_parent"
android:layout_height="100dp" />
</RelativeLayout>
If this does not work, call isFocusable() on your EditText and TextView
addContact.isFocusable(false);
inputName.isFocusable(false);

I am guessing you made a common error. Please check/try both changes.
1) add android:descendantFocusability="blocksDescendants" into the ListView UI ("#+id/lv_main").
Note: If this and 2nd suggestion does not work, then the Listview layout may need rework.
2) mainListView.setItemsCanFocus(false);
Note: The Listview may be confused with focusing on an item in the UI.
I think the suggested code by "Nirmal Shethwala" looks good. It has the if/else block for if (convertView == null).
EDIT: I noticed you inflated 3 xml layout files in getView(). You can only have one, and that is listview_item in your code. I know this is not well documented. I have tried this in the past. The reason is getView() method has to return only one view, and your code return convertView; like me.
Sorry I know this will take some modifications in your layout.

Use Drag handle Id in DragSortListView tag in Xml
dslv:drag_handle_id="#id/drag_handle"
Make an id.xml file and put drag handle id as above to make it common and use the same id on dragable handle image view in your row item.
Hope it helps.

how to change automatically the item id in android listview?

i have a custom adapter to place items inside listview. To customize it i have a listitem.xml file where i set the elements that compose a listitem.
They are as follows:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="50dp" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="5dp"
android:scaleType="fitXY" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/textView1"
android:layout_marginLeft="23dp"
android:layout_marginTop="5dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="" />
<ToggleButton
android:id="#+id/toggleButton1"
android:layout_width="wrap_content"

The problem with this is that now every element in the listitem.xml has exactly the same ID. So every toggle button has the same ID. I dont know which togglebutton the user pressed.
How can i know which togglebutton the user pressed? Do i have to change the way i populate the listview?
Thx very much.
EDIT:
This is how it looks right now and the problem is that the ArrayList that i have to check whether a toggleButton in a row was clicked or not it seems to all set every element to true when i click in another row.
Example:
I have
true | true | true
i click in the third button and i get
true | false | true
but if i click in the first button for example i get
false | true | true
when i should get instead
false | false | true.
Here is the code adapter so someone can take a look.
public class SensorAdapter extends BaseAdapter {
List<sensorItem> sensorList = getDataForListView();
private ToggleButton settingsToggle;
private ArrayList<Boolean> checkedSensors;
#Override
public int getCount() {
return sensorList.size();
}
#Override
public sensorItem getItem(int arg0) {
return sensorList.get(arg0);
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
if (arg1 == null) {
LayoutInflater inflater = (LayoutInflater) Settings.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
arg1 = inflater.inflate(R.layout.listitem, arg2, false);
}
// TextView sensorName = (TextView)
// arg1.findViewById(R.id.textView1);
TextView sensorDescription = (TextView) arg1
.findViewById(R.id.textView2);
ImageView sensorImage = (ImageView) arg1
.findViewById(R.id.imageView1);
settingsToggle = (ToggleButton) arg1.findViewById(R.id.toggleButton1);
settingsToggle.setChecked(true);
checkedSensors = new ArrayList<Boolean>();
int i = 0;
while(i < 10){
checkedSensors.add(i,true);
i++;
}
settingsToggle.setTag(new Long(getItemId(arg0)));
settingsToggle.setOnClickListener(mOnToggleListener);
/*settingsToggle.setOnCheckedChangeListener(new OnCheckedChangeListener(){
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked){
if(isChecked){
Toast.makeText(Settings.this, "on "+buttonView.getId(), Toast.LENGTH_LONG).show();
}
else{
Toast.makeText(Settings.this, "off "+buttonView.getId(), Toast.LENGTH_LONG).show();
}
}
});*/
sensorItem sensor = sensorList.get(arg0);
// sensorName.setText(sensor.sensorName);
sensorDescription.setText(sensor.sensorDescription);
sensorImage.setBackground(sensor.sensorImage);
return arg1;
}
public OnClickListener mOnToggleListener = new OnClickListener(){
#Override
public void onClick(View v){
long id = (Long) v.getTag();
if (checkedSensors.get((int)id)){
//enableSensor(id);
checkedSensors.add((int)id, false);
}else{
//disableSensor(id);
checkedSensors.add((int)id, true);
}
for(int i = 0; i<10 ; i++){
System.out.println(i + " " + checkedSensors.get(i));
}
}
};
public sensorItem getSensor(int position) {
return sensorList.get(position);
}
}
}

You can set the index in a tag on the toggle button so the onClick event knows which index got clicked.
Before you set the onClick listener add this line:
locationToggle.setTag(arg0);
And inside your onClick listener:
int position = (Integer)v.getTag();

you can create your listener ouside of getView like this:
public OnClickListener mOnToggleListener = new OnClickListener() {
#Override
public void onClick(View v) {
//get id of your item from view
//v is locationToggleView
long id = (Long)v.getTag();
}
};
and make these change in getView method:
//set id as view tag when create or reuse view
//arg0 is position
locationToggle.setTag(new Long(getItemId(arg0)));
locationToggle.setOnClickListener(mOnToggleListener);
by this way you can get view related item id when locationToggle is clicked.
