Question

I am developing an android application in which I want to slide images with finger touch. I have implemented an onClickListener with which I can slide images but I don’t know how to implement finger touch functionality.

Please suggest me any method how to slide images with finger touch. Any Suggestion or any tutorial or method will be helpful.

You can use onTouchListner method instead of onClickListner. Below onTouchListners example is given..

public class abc extends Activity implements OnTouchListener 
{
     ImageView img;
     protected void onCreate(Bundle savedInstanceState) 
     {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.one);

                img = (ImageView) findViewById(R.id.imageView1);
                img.setOnTouchListener(this);
     }

        public boolean onTouch(View v, MotionEvent event) 
    {
        switch (event.getAction())
        {
            case MotionEvent.ACTION_DOWN:
            {       
                  // Here u can write code which is executed after the user touch on the screen 
                     break; 
            }
            case MotionEvent.ACTION_UP:
            {             
                   // Here u can write code which is executed after the user release the touch on the screen    
                 break;
            }
            case MotionEvent.ACTION_MOVE:
            {  
               // Here u can write code which is executed when user move the finger on the screen   
                break;
            }
        }
        return true;
    }
