OnTouch事件在底部导航视图上不起作用

Question

OnTouch事件适用于我项目中的Coordinator布局，但不适用于底部导航视图。我不知道为什么，它应该适用于视图，并且底部导航视图是FrameLayout的子类，而FrameLayout是查看。
onTouchListener的代码：

bottomNavigationView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if(motionEvent.getAction() == MotionEvent.ACTION_UP){ //if the thumb is pulled up from the screen
                    // Do what you want
                    Log.d(TAG, "onTouch: up");
                    return true;
                }
                else if(motionEvent.getAction() ==MotionEvent.ACTION_DOWN){ 
                    Log.d(TAG, "onTouch: down");
                    // Construct a rect of the view's bounds
                    rect = new Rect(view.getLeft(), view.getTop(), view.getRight(), view.getBottom());
                    return true;
                }


                if(motionEvent.getAction() == MotionEvent.ACTION_MOVE){
                    if(!rect.contains(view.getLeft() + (int) motionEvent.getX(), view.getTop() + (int) motionEvent.getY())){
                        // User moved outside bounds
                        Log.d(TAG, "onTouch: out of bound");
                    }
                }
                return false;
            }

        });

这是xml布局，其中包含协调器布局和底部导航视图：
