Display the size of an arraylist to a textview

I want to display the size of ArrayList to a textview.

Textview textView;
ArrayList<Integer> mList = new ArrayList<>();
if(mList.size() < 7)
      {
         mList.add(1);
         mList.add(2);
         mList.add(3);
      }
textView.setText(mList.size());

It is giving me Exception:

android.content.res.Resources$NotFoundException: String resource ID #0x2
Solution

  • you may use..

    textView.setText(""+mList.size());

    or

    textView.setText(String.valueOf(mList.size()));

    or

    textView.setText(mList.size().toString());

    mark my answer accepted.
