4) and Finally Create Activity for show Image on listview:-

public class Ecard extends Activity {


private Bundle ext;
private ImageButton back;
private TextView title;
private GridView grid_main;
public ListAdapter imgadp;
private AdView adView;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
   getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
   ext=getIntent().getExtras();
   setContentView(R.layout.ecard);
   grid_main = (GridView)findViewById(R.id.gridView1);
   getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.header1);
        back=(ImageButton)findViewById(R.id.header_left_btn);
        //next=(ImageButton)findViewById(R.id.header_right_btn);
        title=(TextView)findViewById(R.id.header_text);
        title.setText(ext.getString("title"));
        new AddTask().execute();
        back.setOnClickListener(new OnClickListener(){


public void onClick(View arg0) {
// TODO Auto-generated method stub
finish();
}
       
        });
    
grid_main.setOnItemClickListener(new GridView.OnItemClickListener()
{         public void onItemClick(AdapterView<?> a, View v, int i, long l)
{          
  try
  {        
   
       Intent t = new Intent();
               t.setClass(Ecard.this,Ecardfull.class);
               Bundle b=new Bundle();
b.putString("title", "Full Wallpaper");
b.putInt("index", i);
t.putExtras(b);
                startActivity(t);


}          
catch(Exception e)
{  
e.printStackTrace();
System.out.println("Nay, cannot get the selected index");             }  
}    
});
