推荐答案

您可以像这样在主视图上检测投掷手势:

You can detect fling gestures on your main view like this:

final GestureDetector detector = new GestureDetector(new GestureDetector.SimpleOnGestureListener() {
    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        if(velocityX > 0) {
            selectnextImage();
        }
        else {
            selectpreImage();
        }
        return true;
    }
});

view.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getPointerCount() == 1) {
            if(mimage.getScale() == 1f) {
                detector.onTouchEvent(event);
                return true;
            }
            else {
                return false;
            }
        }
        else {
            return false;
        }
    }
});
