移动到上一个片段而不重新加载，同时单击当前片段的后退按钮

Question

我有两个片段。示例FragmentOne和FragmentTwo。在我的     FragmentOne有地图，标记和一个布局。最初的布局状态是     无形。当我点击标记时，一个布局在同一个中可见     分段。当我点击布局时，点击事件会重定向到另一个     片段名称称为FragmentTwo。

now i am in FragmentTwo. my FragmentTwo have a back Button. when i click a 
back button i need to move to FragmentOne. it is working fine. but the 
FragmentOne  shows only the map and marker. i can't able to see the layout.

FragmentOne.

 FragmentOne while redirect from FragmentTwo.

将状态保存在全局变量或其他持久数据中，然后在onResume()中重新加载。 在任何时候Android S.O.将需要卸载片段1，因为建议以这种方式进行。
