Activity——ViewGroup——View

1、默认情况
Activity：

@Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        Log.d("MainActivity","MainActivity dispatchTouchEvent");
        return super.dispatchTouchEvent(ev);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()){
            case MotionEvent.ACTION_DOWN:
                Log.d("MainActivity","MainActivity onTouchEvent down");
                break;
            case MotionEvent.ACTION_UP:
                Log.d("MainActivity","MainActivity onTouchEvent up");
                break;
            default:
                break;
        }
        return super.onTouchEvent(event);
    }

ViewGroup:

@Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        Log.d("MyViewGroup","MyViewGroup dispatchTouchEvent");
        return super.dispatchTouchEvent(ev);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        Log.d("MyViewGroup","MyViewGroup onInterceptTouchEvent");
        return super.onInterceptTouchEvent(ev);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()){
            case MotionEvent.ACTION_DOWN:
                Log.d("MyViewGroup","MyViewGroup onTouchEvent down");
                break;
            case MotionEvent.ACTION_UP:
                Log.d("MyViewGroup","MyViewGroup onTouchEvent up");
                break;
            default:
                break;
        }
        return super.onTouchEvent(event);
    }

View:

 @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        Log.d("MyView","MyView dispatchTouchEvent");
        return super.dispatchTouchEvent(ev);
    }


    @Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()){
            case MotionEvent.ACTION_DOWN:
                Log.d("MyView","MyView onTouchEvent down");
                break;
            case MotionEvent.ACTION_UP:
                Log.d("MyView","MyView onTouchEvent up");
                break;
            default:
                break;
        }
        return super.onTouchEvent(event);
    }
