        lstView1.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView<?> parent, View v,
				int position, long id) {
				
                View layout = inflater.inflate(R.layout.custom_fullimage_dialog,
                        (ViewGroup) findViewById(R.id.layout_root));
