I want to handle onclick on groups of a custom ExpandableListView. With this code I am getting the number of group when clicking on it:
exList.setOnGroupClickListener(new OnGroupClickListener() {
#Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
Log.i("group position", groupPosition + "");
return false;
}
});
I am adding the simplified code. I hope you can figure out what the problem might be:

However, when I click it again, the group closes, BUT i don't get the group number. I only get it, when I open a group.
If I use
exList.setOnGroupClickListener(new OnGroupClickListener() {
#Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
if (groupPosition > 0){
return true;
}
return false;
}
});
I get the group number both times, but then the groups are not opening.
Any ideas?
In onCreate() your setting up your ExpListView (findViewById, adapter, group/child listener etc.). But in refresh() your setting up your ExpListView without setting the listener...you only call findViewById and set the adapter. You have to do the same like youd did in onCreate().
However I don't think it's neccessary that you "reinitialize" your ExpListView in refresh() and you should probably review your code. If you want to I would suggest that you define your ExpListView as member variable and in refresh you remove the line
ExpandableListView exList = (ExpandableListView) findViewById(R.id.layoutExListView);
in your refresh method
However the onGroupClickListener is not working properly, I have found another solution. I used setOnGroupExpandListener and setOnGroupCollapseListener and they are working magically!

listview is working properly
i just inflate cardview in listview.
when using this code image cannot displaying. only dispaly last image in list view
params.height = totalHeight
+ (myListView.getDividerHeight() * (myListAdapter
.getCount() - 1));
my problem is: In listview only displaying last image
check this image:
Try adding your ImageView to Holder class and use like viewholder.img.setImageBitmap(new LoadImage().execute(urll)) and change the return type to Bitmap
Use BaseAdapter instead of ArrayAdapter. Load and show image with UIL, Picasso or other image loader library.
public class ImageAdapter extends BaseAdapter {
private List<ImageBean> list;
private ArrayList<ImageBean> arraylist;
private LayoutInflater inflater;
public ImageAdapter(Context context, List<ImageBean> list) {
this.list = list;
inflater = LayoutInflater.from(context);
this.arraylist = new ArrayList<>();
}
#Override
public int getCount() {
return list.size();
}
#Override
public ImageBean getItem(int position) {
return list.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override

holder.ivImage = (ImageView) convertView.findViewById(R.id.ivImage);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();

// Loading image with UIL example

NewsData_data cannot be resolved to a variable
You need to declare your array outside of the try block so that it is visible to the ArrayAdapter constructor.
As corsair922 mentioned, you'll want to declare your NewsData_data array outside your try catch block, otherwise you won't have access to it from outside the block. Additionally, you want to initialize your array once, and populate the array elements as you go as opposed to reinitializing your array each time:
Edit, I would also recommend you spend some time getting familiar with the Java coding conventions. They will make your code easier to maintain/tidier and will allow other people to better understand your code (http://www.oracle.com/technetwork/java/codeconv-138413.html).

I am working with Section list view in Android to show Call details according to date.
Means under a particular date number of call details. But when I get 2 calls under the same date, the last date is visible only and the list does not show the rest of the calls of that date.
Calls under different dates are shown correctly but calls under same date are not shown correctly, only the last call is shown.

I had query title column from database and want to set it in TextView in GridView.
How?

because you are getting all titles inside model_Inserts List you will need to pass this List to Custom BaseAdapter for showing in TextView as :
Change ShowAllContent() method as:
public void ShowAllContent() {
GridView gridView1 = (GridView) findViewById(R.id.grid_all);
gridView1.setAdapter(new ImageAdapter(TopActivity.this, placeList,model_Inserts));
}
and ImageAdapter constructor as :
public class ImageAdapter extends BaseAdapter {
private ArrayList<HashMap<String, String>> MyArr =
new ArrayList<HashMap<String,String>>();
List<Model_Insert> model_Inserts=null;
public ImageAdapter(Context c,
ArrayList<HashMap<String, String>> myArrayList,
List<Model_Insert> model_Inserts){
context = c;
MyArr = myArrayList;
this.model_Inserts=model_Inserts;
}
///your code here...
now use model_Inserts for getting Title to show inside getView
