        //1.默认经典头布局

//        PtrClassicDefaultHeader defaultHeader = new PtrClassicDefaultHeader(this);

//        给Ptr添加头布局

//        ptrFrameLayout.setHeaderView(defaultHeader);

//        使头布局的状态和刷新状态同步

//        ptrFrameLayout.addPtrUIHandler(defaultHeader);

        //2.模仿MD风格的头布局

//        MaterialHeader materialHeader = new MaterialHeader(this);
