从片段内访问ActionBar [英] Access the ActionBar from within a Fragment

问题描述

如何从片段(android.support.v4.app.Fragment)中访问ActionBar.我正在使用Android支持库v4和v7.我没有使用Sherlock库的.

How do you access the ActionBar from within a Fragment (android.support.v4.app.Fragment). I am using the Android Support Library v4 and v7. I'm not using the Sherlock library's.

承载该片段的活动是一个ActionBarActivity.

The activity hosting the fragment is an ActionBarActivity.

我已经阅读了Android帮助部分片段，这也导致了我的getActivity ()，但没有getSupportActionBar()方法.

I have read the Android help section Fragment which led me too getActivity() but there is no getSupportActionBar() method.

ActionBar actionBar = getActivity().getSupportActionBar()

推荐答案

我已经阅读了Android帮助片段Fragment，它也导致了我getActivity()，但没有getSupportActionBar()方法.

I have read the Android help section Fragment which led me too getActivity() but there is no getSupportActionBar() method.

您需要将getActivity()的结果强制转换为ActionBarActivity，在其上可以找到getSupportActionBar().

You will need to cast the result of getActivity() to be an ActionBarActivity, on which you will find getSupportActionBar().
