分享为什么searchView的子控件是TextView不是EditText？
searchView是一个搜索栏，里面的文字当然是用户可编辑的
老板让我能在屏幕中间输入，搞了一周了，我希望是 popup或者dialog这样，可以点在屏幕外面就删除的
找了好几个模板，但是人家都是最多给你封装为EditText，没有TextView的
我觉得searchView可以看作一个ViewGroup，里面包含的成员变量R.id.search_src_text
但它就是个TextView，真奇怪

谢谢，不知为什么我这里fvbi(search_src_text)返回instanceof 可以是TextView而不是EditText
大概我用了androidX

真正的输入框是 AutoCompleteTextView 是从EditText派生的

SearchView 从LinearLayout派生的。有源码直接看就行了
