list view inside list View in android

I am Using a list view inside a listview and both listview share same list item.
It is working fine but if height of the item increases in inside list view it doesn't wrap the content and put a scrollview which is not as per requirement.
Please see the codes below
activity_main.xml

}
}
please see the highlighted area of image listview height is not proper to wrap the content
any help would be appericiated

The problem is you can't get the scroll of both listview at a time. if you what you both at the same time. you need to create a custom list view try something like this instead of your list view (inside list).
public class NonScrollListView extends ListView {
public NonScrollListView(Context context) {
super(context);
}
public NonScrollListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
}

Their are some points you need to fix.
Give a proper height to your ListView so that it can scroll within that boundry, wrap_content is never recommended for ListView. So better to put some height to your ListView.
Listview inside a ListView will not give the user experience good. Try a work around or better to Use RecyclerView. RecyclerView is better in performance in case of nested list.
Hope it will help :)

How to remove item from ListView and sharedpreferences android studio?

i want to be able to do this to the code i have already I am new to programing please help.
- Add an icon the user can click (per item) to remove it
- When clicked that item on the list should be removed
-The item should be removed from storage as well (so it doesn't appear next time they load up the app)
here is my code:
MainActivity.java

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"

Step1: Create activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

</RelativeLayout>
<Button
android:id="#+id/btnDel"
android:layout_width="fill_parent"

Step2: Create to todo_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:textSize="20sp" />
<CheckBox
android:id="#+id/cbChooseTodo"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
Step3: Define Object Todo
public class ToDoItem {
private String description;
private boolean isComplete;
public ToDoItem(String description, boolean isComplete) {
this.description = description;
this.isComplete = isComplete;
}
public String getDescription() {

}
public void setDescription(String description) {
this.description = description;
}
public boolean isComplete() {
return isComplete;
}
public void setComplete(boolean complete) {
isComplete = complete;
}
}
Step4: Create TodoItemAdapter class
public class TodoItemAdapter extends ArrayAdapter<ToDoItem> {
private ArrayList<ToDoItem> arrayListTodo;
private LayoutInflater layoutInflater;
public TodoItemAdapter(Context context, int resource, ArrayList<ToDoItem> objects) {
super(context, resource, objects);
this.arrayListTodo = objects;
this.layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null){

holder.cbTodoChoose = (CheckBox)convertView.findViewById(R.id.cbChooseTodo);
convertView.setTag(holder);
}else {
holder = (ViewHolder)convertView.getTag();
}
final ToDoItem toDoItem = arrayListTodo.get(position);
holder.tvTodoName.setText(toDoItem.getDescription());
holder.cbTodoChoose.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
toDoItem.setComplete(isChecked);
}
});
holder.cbTodoChoose.setChecked(toDoItem.isComplete());
return convertView;
}
public static class ViewHolder{
public TextView tvTodoName;
public CheckBox cbTodoChoose;
}
}
Step5: Process on the MainActivity class
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private ListView lvTodoItem;
private ArrayList<ToDoItem> toDoItems;
private TodoItemAdapter todoItemAdapter;
private Button btnDel;
private Button btnAdd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initData();
}
private void initData(){
toDoItems = new ArrayList<>();
todoItemAdapter = new TodoItemAdapter(MainActivity.this, R.layout.todo_item, toDoItems);
lvTodoItem = (ListView)findViewById(R.id.lvTodo);
lvTodoItem.setAdapter(todoItemAdapter);
btnAdd = (Button)findViewById(R.id.btnAdd);
btnDel = (Button)findViewById(R.id.btnDel);
btnAdd.setOnClickListener(this);
btnDel.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.btnAdd:
addTodoItem();
break;
case R.id.btnDel:
deleteTodoItem();
break;
}
}
private void addTodoItem() {
}
private void deleteTodoItem() {
for (int i= toDoItems.size()-1; i>=0 ; i--){
ToDoItem toDoItem = toDoItems.get(i);
if (toDoItem.isComplete()){
toDoItems.remove(i);
}
}
todoItemAdapter.notifyDataSetChanged();
}
}
It is working fine. Thanks.

Android: Get values of listview with multiple row layout

I have a listview with multiple row layouts (radio group, edit text, text view), with multiple choice mode. I want to retrieve it's selected data (user-selected or typed data) on a submit button.
This is the code from my main file:
public class GraduatingSurvey extends Fragment {
private static final String LOGTAG = "log" ;
public String stdcode = "024-15-16079";
Button submit;
RadioGroup radioGroup;
RadioButton radioButton;
EditText comment;
ArrayList<GraduatingSurveyModel> graduatingModelList;
ListView listView;
View view;
public GraduatingSurvey() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_graduating_survey, container, false);
submit = (Button) view.findViewById(R.id.btn_graduate_submit);
listView = (ListView) view.findViewById(R.id.graduate_list);
graduatingModelList = new ArrayList<GraduatingSurveyModel>();
//handle submit form Event.
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final int child=listView.getAdapter().getCount();
Log.i("radio", "child: " + child);
SparseBooleanArray checked = listView.getCheckedItemPositions(); //Is returning empty
Log.i("radio", "sparseArray: " + checked);
for(int i=0;i<child;i++) {
int type = listView.getAdapter().getItemViewType(i);
Log.i("radio", "type: " + type);
if(type == 2){
// Want to retrieve data here
}
if(type == 0)
{
}
if(type == 1){
}
}
}
});
NetAsync(view);
return view;
}
This is the adapter:
public class GraduatingSurveyAdapter extends ArrayAdapter<GraduatingSurveyModel> {
private static final int TYPE_ITEM1 = 0;
private static final int TYPE_ITEM2 = 1;
private static final int TYPE_ITEM3 = 2;
int type;
ArrayList<GraduatingSurveyModel> ArrayListSurvey;
int Resource;
Context context;

public GraduatingSurveyAdapter(Context context, int resource, ArrayList<GraduatingSurveyModel> objects) {
super(context, resource, objects);
ArrayListSurvey = objects;
Resource = resource;
this.context = context;
vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getItemViewType(int position) {
if (position == 14){
type = TYPE_ITEM1;
} else if (position == 23 || position == 24 || position == 25){
type = TYPE_ITEM2;
}
else
{
type= TYPE_ITEM3 ;
}
return type;
}
#Override
public int getViewTypeCount() {
return 3;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
//first Item or row is being created hence ConvertView is NULL
if(convertView == null){
if (type == TYPE_ITEM2) {
convertView = vi.inflate(R.layout.graduates_survey_comment,null);
holder = new ViewHolder();
holder.tv_question = (TextView) convertView.findViewById(R.id.graduate_question);
holder.tv_comment = (TextView) convertView.findViewById(R.id.graduate_comment);
}
else if (type == TYPE_ITEM1) {
convertView = vi.inflate(R.layout.graduates_survey_subheader,null);
holder = new ViewHolder();
holder.tv_question = (TextView) convertView.findViewById(R.id.graduate_question);
}
else {
//infalte layout of normaltype
//Inflating items only once
convertView = vi.inflate(Resource,null);
holder = new ViewHolder();
holder.tv_question = (TextView) convertView.findViewById(R.id.graduate_question);
holder.tv_comment = (TextView) convertView.findViewById(R.id.graduate_comment);
holder.rg = (RadioGroup) convertView.findViewById(R.id.graduate_radioGroup);
holder.rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
/* RadioButton radioButton = (RadioButton) group.findViewById(checkedId);
Log.i("radio", "onCheckedChanged: " + radioButton + " " + checkedId);
notifyDataSetChanged();*/
Integer pos = (Integer) group.getTag();
GraduatingSurveyModel element = ArrayListSurvey.get(pos);
switch (checkedId) {
case R.id.graduate_sAgree:

How can I retrieve the data submitted in the main fragment?
Thanks

For this You can create a custom class with row values like,
Arraylist<CustomClass> mnewList = new ArrayList();
Class CustomClass
{
private String edValues,
private int rowId,
}
etc.
Then Implement on change listener for radio button in that add/remove current selected items to that custom list.

Display of ListView include in an other ListView

I have a problem and I can't solve it. I would like to create poll application. I Create 2 classes :
- Poll which contain user's name, the question and an ArrayList of Choice
- Choice contain the choice and its id.
I would like to display on the home page a list of questions (ArrayList) with the differents choices. I managed to display this list but I have a problem with ArrayList of the class Poll because only the first item is display but I want to display all the list of choice.
POLL CLASS
public class Poll{
String question;
String forename;
ArrayList<Choice> list_choices;
public String getQuestion() {
return question;
}
public void setQuestion(String question) {
this.question = question;
}
public String getForename() {
return forename;
}
public void setForename(String forename) {
this.forename = forename;
}
public ArrayList<Choice> getListChoice() {
return list_choices;
}
public void setListChoice(ArrayList<Choice> list_choices) {
this.list_choices = list_choices;
}
}
CHOICE CLASS
public class Choice {
int id;
String choice;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getChoice() {
return choice;
}
public void setChoice(String choice) {
this.choice = choice;
}
}

}

Man, the one and origin solution is:
Set your parent ListView item WRAP_CONTENT height. Next, set fixed height of your included ListView item. Then in getView() method set the height of your included ListView the height equals to parent_array_list.size() * child_list_view_item_height. It might be help you.
Code example:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, (int) (listPolls.size() * TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, child_list_view_item_height, displayMetrics)));
holder.ChoiceView.setLayoutParams(params);

UnsupportedOperationException in creating custom ListView in Android

i wanted to have a custom listView so I did this:
Created an Activity:
public class PRS_MainList_Act extends ListActivity {
MainListAdapter mladp;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_prs__main_list_);
ArrayList<MainMenuItem> menuItems = new ArrayList<MainMenuItem>();
menuItems.add(new MainMenuItem(getResources().getString(R.string.main_list_connectivity), getResources().getString(R.string.main_list_connectivityDesc)));
this.mladp = new MainListAdapter(this, R.layout.man_list_item, R.id.textView1, menuItems);
setListAdapter(mladp);
}
}
Create a class for menu items:
public class MainMenuItem {
private String itemText;
private String itemDescription;
private String itemIMG;
private int itemWeight;
private String itemAssociatedActivity;
public MainMenuItem(String itemText, String itemDescription) {
this.itemText = itemText;
this.itemDescription = itemDescription;
}
public String getItemText() {
return itemText;
}
public void setItemText(String itemText) {
this.itemText = itemText;
}
public String getItemIMG() {
return itemIMG;
}
public void setItemIMG(String itemIMG) {
this.itemIMG = itemIMG;
}
public int getItemWeight() {
return itemWeight;
}
public void setItemWeight(int itemWeight) {
this.itemWeight = itemWeight;
}
public String getItemAssociatedActivity() {
return itemAssociatedActivity;
}
public void setItemAssociatedActivity(String itemAssociatedActivity) {
this.itemAssociatedActivity = itemAssociatedActivity;
}
public String getItemDescription() {
return itemDescription;
}
public void setItemDescription(String itemDescription) {
this.itemDescription = itemDescription;
}
}
Custom array adapter:
public class MainListAdapter extends ArrayAdapter<MainMenuItem> {
ArrayList<MainMenuItem> menuItems;
public MainListAdapter(Context context, int resource,
int textViewResourceId, ArrayList<MainMenuItem> menuItems) {
super(context, resource, textViewResourceId, menuItems);
this.menuItems = menuItems;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (convertView == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.man_list_item, parent);
}
MainMenuItem it = menuItems.get(position);
if (it != null) {
TextView titleTV = (TextView) view.findViewById(R.id.textView1);
TextView descriptionTV = (TextView) view.findViewById(R.id.textView2);
ImageView iconIV = (ImageView)view.findViewById(R.id.imageView1);
if (titleTV != null) {
titleTV.setText(it.getItemText());
}
if(descriptionTV != null){
descriptionTV.setText(it.getItemDescription());
}
if(iconIV != null){
if(it.getItemText().equals(getContext().getResources().getString(R.string.main_list_connectivity)))
iconIV.setImageResource(R.drawable.network_connections);
}
}
return view;
}
}
and here are my activity layout and item layout:
<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"
tools:context=".PRS_MainList_Act" >
<ListView android:id="#android:id/list"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</LinearLayout>
Item Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:src="#drawable/ic_launcher" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"

</LinearLayout>
I got this error saying: java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView
Thanks in advance for your help.

You can't use this version of the inflate method:
view = vi.inflate(R.layout.man_list_item, parent);
because this will add the inflated View to the parent, which isn't allowed in a ListView. Instead use this version:
view = vi.inflate(R.layout.man_list_item, parent, false);
which will inflate the view but will not add it to the parent. This version is important because it will provide the proper LayoutParams for your inflated view.
