推荐答案

您可以使用onTouchListner方法，而不是onClickListner。下面onTouchListners例说明。

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;
    }
