我尝试了以下解决方案，没有人为我工作。
1）When inflating fragment which was previously inflated app crashes
2）android.view.InflateException: Binary XML file line #20: Error inflating class fragment我认为没有嵌套片段
我在第一次完成后运行应用程序时遇到崩溃Error inflating class fragment。
当Open App第一次一切都很好。当打开应用程序第二次崩溃。当第三次打开然后app工作正常。等等。
以下是我的Activity片段
<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->

android:layout_gravity="left" instead.

您可以尝试替换此行：
`android:name="com.taazi.Fragments.NavigationDrawerFragmentLeft"`
与
class = "com.fragment.NavigationDrawerFragment"
