Question

    LayoutInflater inflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View row=inflater.inflate(R.layout.single_row, parent, false);
    ImageView myImage= (ImageView) row.findViewById(R.id.imageView);
    TextView myNames= (TextView) row.findViewById(R.id.contact_name);
    TextView myNumbers= (TextView) row.findViewById(R.id.contact_num);
    Button btn= (Button) row.findViewById(R.id.caller_button);
    myImage.setImageResource(images[position]);
    myNames.setText(nameArray[position]);
    myNumbers.setText(numberArray[position]);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

        }
    });
    return row;
}
}

Answer 1

Here is what I do:

private class MyAdapter extends BaseAdapter {
   private ListView listView;
   ...
   @Override
   public View getView(int i, View view, ViewGroup viewGroup) {
      this.listView = (ListView) viewGroup;

and then in each View.OnClickListener I can get the position of the clicked item by

@Override
public void onClick(View view) {
   ...
   MyAdapter.this.listView.getPositionForView((View) view.getParent()));
