在Android中获取Fragment中的应用程序上下文? [英] Get the Application Context In Fragment In Android?

问题描述

我通过在一个活动中使用应用程序上下文将一些数据存储到全局类.后来我必须在片段中检索这些值.我已经做了这样的事情来存储在全局类中.

I have stored some data to a Global Class By using the Application Context In One Activity. Later I have to Retrieve those values in A Fragment. I have done something like this to store in Global Class.

AndroidGlobalClass  AGC = ((AndroidGlobalClass) getApplicationContext());
AGC.setUser_access("XYZ");
AGC.setFirst_name("ABC");

在我已经完成的清单中:

And In the Manifest I have done :

<application
    android:name=".AndroidGlobalClass"
    android:theme="@style/AppTheme" >
    <activity
       android:name="abc.SignInActivity"
       android:label="@string/app_name" >
       <intent-filter>
          <action android:name="android.intent.action.MAIN" />
          <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>
    </activity>
</application>

现在，当我尝试使用此获取应用程序上下文时...我没有获取上下文...

Now When I am Trying to Get the Application Context Using this... I am not getting the Context...

AndroidGlobalClass  AGC = ((AndroidGlobalClass) getApplicationContext());

这是我的片段活动

public class Fragment_NewsFeed extends Fragment {
    public Fragment_NewsFeed() {
    }

    RestImplimentationMethods RIM;
    AndroidGlobalClass AGC;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_newsfeed, container, false);
        return rootView;
    }
}

推荐答案

您可以使用getActivity().getApplicationContext();
