Filter for Axis Y on MotionEvent object

Question

Is there a way to create a new object from a MotionEvent object that extract only the X axis movement (gesture) ?

@Override
public boolean onTouchEvent(MotionEvent event) {
MotionEvent xMotionEvent = filterYMotion(event);
return super.onTouchEvent(xMotionEvent);
}

Thanks.

if you want to "zero" y values use transform() – pskink Dec 05 '13 at 19:57 — pskink, Dec 05 '13 at 19:57

You could use this code to only extract the x value:

event.getX();

@Override
    public boolean onTouchEvent(MotionEvent event) {
        Matrix matrix = new Matrix();
        matrix.setScale(1, 0);
        event.transform(matrix);
        return super.onTouchEvent(event);
    }
