How to move the first position of image to second position in ListView on Button click,so that last position of image will comes to first position.

my tried codes below;

public class MainActivity extends AppCompatActivity {

private int[] images = {R.drawable.img1,R.drawable.img2,R.drawable.img3,R.drawable.img4,R.drawable.img5};
ArrayList<ImageModel> imageModels;

@Override
protected void onCreate (Bundle savedInstanceState) {
    super.onCreate (savedInstanceState);
    setContentView (R.layout.activity_main);

    imageModels = new ArrayList<ImageModel> ();
    for (int i = 0; i < images.length; i++) {
        ImageModel imgMode = new ImageModel ();
        imgMode.setImageId (images[i]);
        imageModels.add (imgMode);
        Log.d ("chk",""+images[i]);
    }

    ListView lstView = (ListView)findViewById (R.id.lst_view);
    lstView.setAdapter (new BaseAdapterr(MainActivity.this,imageModels));

    Button btnClick = (Button)findViewById (R.id.btn_click);
    btnClick.setOnClickListener (new View.OnClickListener () {
        @Override
        public void onClick (View v) {
           for (int i=0 ;i < imageModels.size ();i++){
           }
        }
    });
}}

Try using getting the object index and then use setIndex or sth like that for changing index.

Tarik.
