错误InflateException Android 6.0

Question

我试着运行我的应用程序时出错。我试图通过导入将类更改为扩展片段和扩展片段活动，但没有成功。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。

我认为在使用SupportLibraries AppCompatActivity时，应该使用android:name=“com.google.android.gms.maps.SupportMapFragment”，而不是android:name=“com.google.android.gms.maps.MapFragment”。

出于同样的原因，我认为您还应该将getFragmentManager（）替换为getSupport portFragmentManager（）。

在支持库和常规API中拥有相同的类有时真的很麻烦，因为您必须始终确保使用正确的类。
