            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            	
            	switch( position )
                {
                   case 0:  Intent newActivity0 = new Intent(getApplicationContext(), comosellamelatuya.class);     
                            startActivity(newActivity0);
                            break;
                   case 1:  Intent newActivity1 = new Intent(getApplicationContext(), comosellamelatuya.class);     
                            startActivity(newActivity1);
                            break;
                   case 2:  Intent newActivity2 = new Intent(getApplicationContext(), comosellamelatuya.class);     
                            startActivity(newActivity2);
                            break;
                   case 3:  Intent newActivity3 = new Intent(getApplicationContext(), comosellamelatuya.class);     
                            startActivity(newActivity3);
                            break;
                   case 4:  Intent newActivity4 = new Intent(getApplicationContext(), comosellamelatuya.class);     
                            startActivity(newActivity4);
                            break;
                
            	}
