如何在Fragment中监听触摸事件

How to handle Touch Events on a Fragment?

直接对根布局进行监听

View view = inflater.inflate(R.layout.fragment_test, container, false);

    view.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {

                if(event.getAction() == MotionEvent.ACTION_MOVE){
                    //do something
                }
                return true;
            }
    });

//here the rest of your code

return view;

打开百度搜索，翻来覆去就是一篇文章的复制，使用根Activity注册监听到Fragment。
