I have a bitmap I'd like to "fling". I'm struggling to get it to fling with ontouchlistener due to it being a bitmap and I'm not sure how to proceed.
To clarify, I don't know how to "fling" the object and what I have doesn't work and I'm asking how to do it for a specific object on the screen rather than the whole screen or an item menu.
Current code Gesture Code:
package com.main.shapes;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;
public class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
//From Right to Left
return true;
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
//From Left to Right
return true;
}
if (e1.getY() - e2.getY() > SWIPE_MIN_DISTANCE && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
//From Bottom to Top
return true;
} else if (e2.getY() - e1.getY() > SWIPE_MIN_DISTANCE && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
//From Top to Bottom
return true;
}
return false;
}
@Override
public boolean onDown(MotionEvent e) {
//always return true since all gestures always begin with onDown and<br>
//if this returns false, the framework won't try to pick up onFling for example.
return true;
}
}
I have the "ball" created in my MainActivity class, how would I call the onFling event of the ball? i.e, add the gesture listener to the ball (or each object randomly generated)?
