android.support.v4.app.FragmentActivity扩展了什么？
[英]What does android.support.v4.app.FragmentActivity extend?
问题描述
The webpage with the following address states that the class FragmentActivity extends the class Activity: 
具有以下地址的网页指出FragmentActivity类扩展了Activity类：
https://developer.android.com/reference/android/support/v4/app/FragmentActivity.html https://developer.android.com/reference/android/support/v4/app/FragmentActivity.html
However, when I bring up the documentation for the android.support.v4.app.FragmentActivity class within Android Studio, it states that FragmentActivity extends android.support.v4.app.BaseFragementActivityHoneycomb. 但是，当我调出Android Studio中android.support.v4.app.FragmentActivity类的文档时，它指出FragmentActivity扩展了android.support.v4.app.BaseFragementActivityHoneycomb。
What is the reason for the discrepancy and which is correct? 出现差异的原因是什么，哪个是正确的？

This goes up to BaseFragmentActivityDonut . 这取决于BaseFragmentActivityDonut 。 These base fragments are just an implementation detail of FragmentActivity and should not concern you at all. 这些基本片段只是FragmentActivity的实现细节，完全不关心您。 In the library I use, FragmentActivity directly extends BaseFragmentActivityJB . 在我使用的库中， FragmentActivity直接扩展BaseFragmentActivityJB 。 In the future there might be something like BaseFragmentActivityM or some compatibility layer for even newer platforms. 将来可能会出现诸如BaseFragmentActivityM类的BaseFragmentActivityM或者甚至对于较新的平台也可能会有一些兼容性层。
For your programming just assume it extends Activity only, like the documentation states. 对于您的编程，只需假设它像文档说明中那样仅扩展了Activity 。
