Попробуйте это:

trailer.setOnClickListener(new View.OnClickListener() {             
    @Override
    public void onClick(View v) {
          Intent webIntent = new Intent(Intent.ACTION_VIEW,
          Uri.parse(MovieDB.geturl(movieNames[position])));
      try {
         MainActivity.this.startActivity(webIntent);
      } catch (ActivityNotFoundException ex) {
      }
   }
});
