EditText没有捕获ViewFlipper flings？

ViewFlipper viewFlipper = findViewById(R.id.viewFlipper);
EditText editText = findViewById(R.id.editText);

viewFlipper.setOnTouchListener(new View.OnTouchListener() {
    private float startX;
    private float startY;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                startX = event.getX();
                startY = event.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                float endX = event.getX();
                float endY = event.getY();
                float distanceX = Math.abs(endX - startX);
                float distanceY = Math.abs(endY - startY);
                if (distanceX > distanceY) {
                    // 用户水平滑动，拦截事件
                    viewFlipper.requestDisallowInterceptTouchEvent(true);
                }
                break;
            case MotionEvent.ACTION_UP:
                viewFlipper.requestDisallowInterceptTouchEvent(false);
                break;
        }
        return false;
    }
});
