A problem that I am facing which is, When I am changing the ImageView Resource inside the ExpandableListView child. I am setting different Child for Different parent and then I am handling the button click inside one of the parent-child as (Here I am doing all this in groupPosition ==3):

Please help me out.
The view which you want to change should be declared inside childView method and if you want to change ImageSwitcher View on click of Button then you can define it as Final variable inside childView method.
So childView Method would be like below
public View getChildView(int groupPosition, int childPosition, boolean b, View convertView, ViewGroup viewGroup) {
LayoutInflater infalInflater = (LayoutInflater) this.mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
String headerTitle = (String) getGroup(groupPosition);
int childType = getChildType(groupPosition, childPosition);
String parent = ((String) getGroup(groupPosition));
if(convertView == null){
switch (childType){
case CHILD_TYPE_1:
convertView = infalInflater.inflate(R.layout.booking_status_child_layout, null);
convertView.setTag(childType);
break;
case CHILD_TYPE_2:
convertView = infalInflater.inflate(R.layout.filterby_child_layout, null);
convertView.setTag(childType);
break;
case CHILD_TYPE_3:
convertView = infalInflater.inflate(R.layout.transfer_status_child_layout, null);
convertView.setTag(childType);
break;
case CHILD_TYPE_4:
convertView = infalInflater.inflate(R.layout.sort_by_date_child_layout, null);
convertView.setTag(childType);
break;
default:
break;
}
}
switch (childType){
case CHILD_TYPE_1:
break;
case CHILD_TYPE_2:
break;
case CHILD_TYPE_3:
break;
case CHILD_TYPE_4:
btm = (Button) convertView.findViewById(R.id.btm);
btm1 = (Button) convertView.findViewById(R.id.btm1);
final ImageSwitcher bookedonImage= (ImageSwitcher) convertView.findViewById(R.id.booedOnImage);
btm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
bookedonImage.setImageResource(R.drawable.ascending_active);
}
});
btm1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
bookedonImage.setImageResource(R.drawable.decending_active);
}
});
break;
}
return convertView;
}
