Android - How to end a Fragment
提问by user222786
In my application I have a navigation drawer, and the way my app works is there is only one activity and if you select something from the Navigation drawer it starts/replaces the current fragment. How Can I make it so that when something is selected from the navigation drawer and a new fragment starts the old fragment ends
在我的应用程序中，我有一个导航抽屉，我的应用程序的工作方式是只有一个活动，如果您从导航抽屉中选择某些内容，它会启动/替换当前片段。我如何才能做到当从导航抽屉中选择某些内容并且新片段开始时旧片段结束
I cant do
我做不到
@Override
public void onPause() {
// TODO Auto-generated method stub
super.onPause();
getActivity().finish();
}
because that would kill the app since there is only one activity.
因为这会杀死应用程序，因为只有一项活动。
How do I kill the fragment?

If you are using dynamic fragments, set up via a FragmentTransaction, you could run a transaction to replace()the old fragment with the new one.
如果您使用的是通过 设置的动态片段，则FragmentTransaction可以replace()使用新片段对旧片段运行事务。
