Thanks to sam he point out error; Now i want to display text below every image. so i am trying to implement relative layout and following code but it does not working.

Here is my code

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.cfragment, container, false);
    }
@Override
public void onStart() {
    super.onStart();
    /** Setting the multiselect choice mode for the listview */
    initfrag();
}
private void initfrag() {
    RelativeLayout layout = new RelativeLayout(getActivity());
     TextView tv1 = new TextView(getActivity());
     tv1.setText("xyzxyzyxyzxyz"); tv1.setId(1);
     TextView tv2 = new TextView(getActivity());
     tv2.setText("xyzxyzyxyzxyz");tv2.setId(2);
     RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
             RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
     lp.addRule(RelativeLayout.BELOW, tv1.getId());
     layout.addView(tv1);        
     layout.addView(tv2, lp);
    final LinearLayout linearlayout1 = (LinearLayout)getView().findViewById(R.id.container);
    LinearLayout linearlayout2 = (LinearLayout)getView().findViewById(R.id.container2);
    LinearLayout linearlayout3 = (LinearLayout)getView().findViewById(R.id.container3);
    for (int i = 0; i < 15; i++) { 
        iv = new ImageView(getActivity());
        iv.setPadding(20, 5, 5, 5);
        iv.setId(i);
         iv.setImageResource(R.drawable.test_play_image);
         linearlayout1.addView(iv, 200, 220);
         ImageView iv2 = new ImageView(getActivity());
         iv2.setPadding(20, 5, 5, 5);
         iv2.setImageResource(R.drawable.test_play_image);
         linearlayout2.addView(iv2, 200, 220);

         ImageView iv3 = new ImageView(getActivity());
            iv3.setPadding(20, 5, 5, 5);
             iv3.setImageResource(R.drawable.test_play_image);
             linearlayout3.addView(iv3, 200, 220);
             iv.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    int s =iv.getId();
                    Toast t = Toast.makeText(getActivity(), "id is "+s, Toast.LENGTH_SHORT);
                    t.show();
                }
            });

You want to get the id of the View that you just clicked, not the last View created in your loop. So simply change the variable in your OnClickListener from iv :

int s =iv.getId();

To v , the View passed to onClick() :

int s = v.getId();
