我编写了一个navigationdrawer并为其创建了一个新样式，然后在片段中放置了一个recyclerview现在我得到了以下错误：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.myfood.app/com.myfood.app.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

没有回收站，一切正常。

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener
