implement GestureDetector for an ImageView

android, gesturedetector, imageview

Solution

public class TestImageView extends ImageView  implements OnGestureListener{
    public TestImageView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub

        setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // TODO Auto-ge`enter code here`nerated method stub
                return false;
            }
        });
    }

    @Override
    public boolean onDown(MotionEvent e) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public void onLongPress(MotionEvent e) {
        // TODO Auto-generated method stub

    }

    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
            float distanceY) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public void onShowPress(MotionEvent e) {
        // TODO Auto-generated method stub

    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        // TODO Auto-generated method stub
        return false;
    }
}

Now you can use TestImageView in your xml instead of just ImageView.

Problem

Good moorning : I have an ImageView in my Activity and I setted the OntOuchListner() to my ImageView, which means that I implemented that interface for my ImageView like this : ``` public class mapActivity extends Activity { //-------------------------------------- private ImageView imageView; /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageView = (ImageView) this.findViewById(R.id.imageView1); AddImageViewEvents(); } private void AddImageViewEvents() { imageView.setOnTouchListener(new ImageView.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int action, pointerCount, i; action = event.getAction(); pointerCount = event.getPointerCount(); switch (action) { case MotionEvent.ACTION_DOWN: //code here break; case MotionEvent.ACTION_MOVE: //code here break; default: break; } return true; } } ``` I want by the same way set the GestureDetector to my ImageView, I don't know if this is possible. Thanks.
