无法从活动调用getSupportFragmentManager（） [英] Cannot call getSupportFragmentManager() from activity

问题描述

我有其中有一个片段的活动。​​

I have an activity which has a fragment.

XML：

 <fragment android:name="com.example.androidcalculator.ResultFragment"
            android:id="@+id/result_fragment"
            android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

和我想从活动的方法调用从ResultFragment的方法，但getSupportFragmentManager不存在：

And I want to call a method from ResultFragment from a method in the Activity, but getSupportFragmentManager "doesn't exist":

FragmentManager fragMan = getSupportFragmentManager();

我该如何解决此问题？

How can I resolve this?

推荐答案

您的活动不会延长<一个href="http://developer.android.com/reference/android/support/v4/app/FragmentActivity.html">FragmentActivity从支持库，因此该方法不是present在超

Your activity doesn't extend FragmentActivity from the support library, therefore the method is not present in the superclass

如果你的目标API 11或以上，你可以使用<一个href="http://developer.android.com/reference/android/app/Activity.html#getFragmentManager%28%29">Activity.getFragmentManager代替。

If you are targeting api 11 or above, you could use Activity.getFragmentManager instead.
