Step 1: Place the on click listeners after this line(viewHolder = (ViewHolder)convertView.getTag())
Step 2: In onclick method remove view creations/delete logics. Change the model value("In your case current Item flag") and call notifyDataset changed method
@Override
public void onClick(View view) {
//Set the flag based on your view click
((DOT_Common_Model) getItem( int position)).setFlag(0);
notifyDatasetChanged();
}
Step 3: Change the view based on your model value("flag value")
if(((DOT_Common_Model) getItem( int position)).getFlag()==0){
view1.setVisibility(View.VISIBLE);
view2.setVisibility(View.GONE);
view3.setVisibility(View.GONE);
}else if(((DOT_Common_Model) getItem( int position)).getFlag()==1){
view1.setVisibility(View.GONE);
view2.setVisibility(View.VISIBLE);
view3.setVisibility(View.GONE);
}else if(((DOT_Common_Model) getItem( int position)).getFlag()==2){
view1.setVisibility(View.GONE);
view2.setVisibility(View.GONE);
view3.setVisibility(View.VISIBLE);
}else{
view1.setVisibility(View.VISIBLE);
view2.setVisibility(View.VISIBLE);
view3.setVisibility(View.VISIBLE);
}
Note: List view only binds the data and it never changes the viewholder view object for every data value, we need to change the views visibility/background based on the data value. If you use "if condition" then "else" must be there.
