This is my Adapter class.in this we want to set diffrent value of all child and parent field but same value set on all field.
you can see the the output in this image..
enter image description here
How can i solve this problem, I can not understant.
please help.
Please correct getChildView method gand etGroupView method. The code will be as follows.
public View getChildView(int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
String slNo = _slNo.get(_userID.get(groupPosition)).get(0);
String childName = _name.get(_userID.get(groupPosition)).get(0);
String childCity = _city.get(_userID.get(groupPosition)).get(0);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this._context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_item, null);
}
TextView txtListChildslno = (TextView) convertView.findViewById(R.id.lblListItemslno);
TextView txtListChildname = (TextView) convertView.findViewById(R.id.lblListItemname);
TextView txtListChildcity = (TextView) convertView.findViewById(R.id.lblListItemcity);
txtListChildslno.setText(slNo);
txtListChildname.setText(childName);
txtListChildcity.setText(childCity);
return convertView;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater infalInflater=(LayoutInflater)this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.list_group, null);
}
TextView lblListHeaderuserid = (TextView) convertView.findViewById(R.id.lblListHeaderuserid);
TextView lblListHeaderjoindate = (TextView) convertView.findViewById(R.id.lblListHeaderjoindate);
lblListHeaderuserid.setText(headerTitle);
lblListHeaderjoindate.setText(_joiningDate.get(groupPosition));
return convertView;
}
Hope that you can understand what was your mistake..
I tested the code, it will work.

I have put tabs insilde a expandablelistview adapter and due to its getCHildView method tabs are generating multiple times in on parent click. How to resolve this .
This is an example of what I need to implement.
http://i.stack.imgur.com/rvPZe.png
In left side image there is list of expandable view to be shown to user. Once user click on any of the expandable view i need to display tabs inside childlistview of expandable list view as shown in right image.

After doing little amount of research I got to know that the problem is with convert view which you are reusing for the child once it gets created once. But not for the TabHost. You are creating the TabHost every time even if the view is already gets created and also tabhost setup is also done for the same child.I have just edited adapter class and for research one method prepareListData(). SO here is the edited code:-
MyExpandableListAdapter.java
public class MyExpandableListAdapter extends BaseExpandableListAdapter {
private Context _context;
private Button b;

// child data in format of header title, child title

Well, easy one.
You have imagebutton in groupview that is intercepting touch event. Add these parameters:
android:focusable="false"
android:focusableInTouchMode="false"
And do same for childview. You have exactly the same case there.
P.S. why are you using imagebuttons anyway? you could use imageviews instead
You need to do this one.
expandableListView = (ExpandableListView)view.findViewById(R.id.expd_list_view);
SubjectAdapter adapter = new SubjectAdapter(getActivity(),subjectName,topicName);
expandableListView.setAdapter(adapter);
expandableListView .setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
#Override
public boolean onGroupClick(ExpandableListView expandableListView, View view, int groupPosition, long l) {
expandableListView.expandGroup(groupPosition);
return false;
}
});
Hope this will help you.
Try to pass your ExpandableListView in the adapter:
SubjectAdapter adapter = new SubjectAdapter(getActivity(),subjectName,topicName, expandableListView);
Then youe adapter should look like:
...
ExpandableListView expandableListView;
public SubjectAdapter(Context context, ArrayList<String> subjectName, HashMap<String, ArrayList<String>> topicName, ExpandableListView expandableListView) {
this.context = context;
this.topicName = topicName;
this.subjectName = subjectName;
this.expandableListView = expandableListView;
}
In your group view add following:
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
expandableListView.expandGroup(groupPosition);
}
});
I have no idea what's wrong with this code my onChildClickListener() is not called I have seen some answers in which they said override isChildSelected and return true; i tried that too but still it's not getting called. Can anybody help me in this. Any help would be appreciated. Thanks.

It is possible that your ImageView and possibly TextViews in the child layout are intercepting the click events. In your XML, try adding android:focusable="false" to all those elements.
I implement an ExpandableList in my app.
when i finish it work totally wrong.
List have only one row and in it display child data in row title view,
Here is my code :
My list adpater :
public class JoinUsAdapter extends BaseExpandableListAdapter {
public static final String DESCRIPTION_TG = "description";
public static final String TITLE_TG = "title";
private Context mContext;
private List<Map<String, String>> mData;
private LayoutInflater inflater;
private ViewHolder vholder;
public JoinUsAdapter(Context context, List<Map<String, String>> data) {
this.mContext = context;
this.mData = data;
inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getGroupCount() {
return mData.size();
}
#Override
public int getChildrenCount(int groupPosition) {
return 1;
}
#Override
public Map<String , String> getGroup(int groupPosition) {
return mData.get(groupPosition);
}
#Override
public String getChild(int groupPosition, int childPosition) {
return mData.get(groupPosition).get(DESCRIPTION_TG);
}
#Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return 1;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.row_title_join_us, null);
vholder = new ViewHolder();
vholder.txtTitle = (TextView) convertView.findViewById(R.id.txtNewsTitle);
vholder.txtShortDesc = (TextView) convertView.findViewById(R.id.txtNewsShortDesc);
convertView.setTag(vholder);
}
else {
vholder = (ViewHolder) convertView.getTag();
}
Map item = getGroup(groupPosition);
vholder.txtTitle.setText(item.get(TITLE_TG).toString());
vholder.txtTitle.setText(truncate(item.get(DESCRIPTION_TG).toString(),35)+" ...");
return convertView;
}
#Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.row_detail_join_us, null);
}
TextView txtLongDesc =(TextView) convertView.findViewById(R.id.txtLongDescription);
txtLongDesc.setText(getChild(groupPosition,childPosition));
return convertView;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;
}
And here is my Layouts :
title(as list row view) :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:id="#+id/txtNewsTitle"

I cant find where is my mistake :/
Update:
My method for create fake data :
public void getData() {
dataList = new ArrayList<Map<String, String>>();
Map<String, String> item = new HashMap<String, String>();
String fake = "We asked respondents how satisfied they are with their current job or jobs. 76% of developers report being at least satisfied with their job, and 36% love their job. Developers are generally more fulfilled by work than most employees.\n" +
"\n" +
"And developers in Iran are more satisfied with their jobs than developers anywhere else. Stack Overflow Careers may not have any jobs available in Iran, but you can still move there and apply for one of our many available remote jobs.";
for(int i=0; i<10; i++) {
item.put(JoinUsAdapter.TITLE_TG,"Title "+i);
item.put(JoinUsAdapter.DESCRIPTION_TG,fake);
dataList.add(item);
}
