Java 如何将ScrollView添加到导航抽屉

我想将ScrollView添加到导航抽屉中，我第一次尝试在ScrollView下创建线性布局，但当我打开片段时，导航抽屉显示在片段下。我想让我的片段保持不变，而导航抽屉现在显示在片段后面，导航抽屉有滚动视图

public class drawer_home extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {


private DrawerLayout drawer;
Toolbar toolbar;

TextView mStartDate, mEndDate, mPlan, mDays;
FirebaseAuth firebaseAuth;
FirebaseUser user;
FirebaseDatabase firebaseDatabase;
DatabaseReference databaseReference;

            R.string.navigation_drawer_open, R.string.navigation_drawer_close);

        drawer.closeDrawer(GravityCompat.START);
    } else {
        super.onBackPressed();
    }


}

}

xml:

当主要内容可滚动时，它显示在第一个片段下



我想你必须

<com.google.android.material.navigation.NavigationView
    ...
    android:fitsSystemWindows="true"
    android:isScrollContainer="true"
    ... />

我想您必须设置

<com.google.android.material.navigation.NavigationView
    ...
    android:fitsSystemWindows="true"
    android:isScrollContainer="true"
    ... />

得到了很多帮助并解决了这个问题

添加scrollview以分离片段并合并到onCreate中
