Use your OnClickListener() in your activity after .setAdapter() method, not in your adapter class.

gridView.setAdapter(adapter);
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
    Toast.makeText(GridViewActivity.this, "" + position,
             Toast.LENGTH_SHORT).show();
    }
});
