android中自定义对话框的滑动动作

public class CustomDialog extends Dialog {
    private GestureDetector gestureDetector;

    public CustomDialog(Context context) {
        super(context);
        // 初始化GestureDetector
        gestureDetector = new GestureDetector(context, new GestureListener());
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // 将触摸事件传递给GestureDetector处理
        return gestureDetector.onTouchEvent(event);
    }

    private class GestureListener extends GestureDetector.SimpleOnGestureListener {
        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY) && Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        // 向右滑动
                        // 执行相应操作
                    } else {
                        // 向左滑动
                        // 执行相应操作
                    }
                    result = true;
                }
            } catch (Exception exception) {
                exception.printStackTrace();
            }
            return result;
        }
