Question

How can I retrieve the View at the position X in a ListView? I dont want to inflate a new one, just retrieve the cell visible in the screen for change some parameters programmatically

Found a dirty solution:

1. You should be able of identify each row generated. For example adding a TextView with visibility=gone and writing a unique value there when generating (or recycling the row)
2. In the listactivity call to getListView.setSelection(position) to the desired cell

3. Survey the listview list for the row (until displayed)

   lv=getListView();
   for (int i=0;i <lv.getChildCount();i++){
      if (((TextView)lv.findViewById(R.id.my_hidden_textview)).getText.equals(mykey)){
      // view found
      } else {
      // schedule another survey "soon"
      }
    }
   

   For the schedule you can use something like:

   final int RETRY_DELAY=100;
   new Handler(){
       public void handleMessage(Message msg){
          if (msg.what<0) return; //something went wrong and retries expired
                  lv=getListView();
          for (int i=0;i <lv.getChildCount();i++){
            if (((TextView)lv.findViewById(R.id.my_hidden_textview)).getText.equals(mykey)){
               //result = lv.findViewById(R.id.my_hidden_textview);
            } else {
               this.sendEmptyMessageDelayed(msg.what-1,RETRY_DELAY);
            }
          }     
       }
   }.sendEmptyMessageDelayed(10,RETRY_DELAY);
   

As I said is a very ugly solution but it works
