Question

下面的代码在5.0上工作正常，但在4.4.4上它会运行到

D/AndroidRuntime﹕ Shutting down VM
W/dalvikvm﹕ threadid=1: thread exiting with uncaught exception (group=0xb0d42b20)
E/AndroidRuntime﹕ FATAL EXCEPTION: main
Process: com.example.xxx.xxx, PID: 2352
android.view.InflateException: Binary XML file line #6: Error inflating class <unknown>

    NavigationDrawerFragment drawerFragment = (NavigationDrawerFragment)
      getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
    drawerFragment.setUp(R.id.fragment_navigation_drawer,(DrawerLayout)findViewById(R.id.drawer_layout), toolbar);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
  }

  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
      return true;
    }

    return super.onOptionsItemSelected(item);
  }
}

    android:layout_gravity="start"
    app:layout="@layout/fragment_navigation_drawer"
    tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>

为什么这个错误只会出现在KitKat而不是Lollipop上？据我所知，我的导入都是android.support.v4或.v7，应该适用于4.4。

对于答案你可能已经太迟了而且你已经解决了，但作为回应我最近遇到了同样的问题，结果发现＆＃39; Theme.AppCompat ... ＆＃39;以我的风格导致棒棒糖前的膨胀异常并将其更改为＆＃39; android：Theme.Holo ... ＆＃39;让问题消失了。

对于解决方案，您应该对样式中的所选主题执行某些操作。

希望有所帮助。

4.4.4上的android.view.InflateException，而5.0则没问题
