How Communicate Between Adapter And Activity

I'm not sure what's the best way to communicate from an Adapter to the corresponding Activity. My activity has a layout with a WebView and a Gallery on top of it:

Solution 1:

Instead creating Imageview's click listener, use gallery's setOnItemClickListener

 yourGallery.setOnItemClickListener(new OnItemClickListener() 
 {
     @Override
     publicvoidonItemClick(AdapterView<?> arg0, View arg1,int position, long arg3) {

         system.out.println("position"+position);               

     }
 });

Solution 2:

Use the setOnItemClickListener method of your Gallery object in the activity.
