错误 InflateException Android 6.0

Question

当我尝试运行我的应用程序时出现错误。我尝试使用导入将类更改为extends Fragment 和extends FragmentActivity，但没有奏效。 因为我在我的清单中添加了一些额外的信息，我认为您可能有一些可能导致报告的问题。

我认为您应该使用 android:name="com.google.android.gms.maps.SupportMapFragment" 而不是 android:name="com.google.android.gms.maps.MapFragment"，因为您正在使用 SupportLibraries AppCompatActivity。

出于同样的原因，我认为您也应该将getFragmentManager() 替换为getSupportFragmentManager()。

在支持库和常规 API 中使用相同的类有时真的很痛苦，因为您始终必须确保使用正确的类。
