android-studio - 如何在抽屉导航中添加切换按钮

Question

我想使用抽屉导航中的开关按钮从主布局中添加和删除片段。

这是我的代码-
菜单项.xml`

<group
    android:id="@+id/drawer_group1"
    android:checkableBehavior="single">
    <item
        android:id="@+id/nav_timer"
        android:icon="@drawable/ic_timer"
        android:title="Timer">

    </item>

    <item
        android:id="@+id/addFragment_Bt"
        app:actionViewClass="android.widget.Switch"
        android:title="Most Used" />
    <item
        android:id="@+id/nav_settings"
        android:icon="@drawable/ic_settings"
        android:title="Settings">

    </item>
</group>`

主Activity.class

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
    switch (menuItem.getItemId()) {
        switch (menuItem.getItemId()) {
            case R.id.addFragment_Bt:

                Switch switchCompat = findViewById(R.id.addMostUsed_Bt);
                switchCompat.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                    @Override
                    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                        FragmentManager fragmentManager = getSupportFragmentManager();
                        Fragment fragment = fragmentManager.findFragmentById(R.id.Most_Used_Fragment_container);
                        if (isChecked == true) {
                            if (fragment != null) {
                                fragmentManager.popBackStack();
                            }

                        }
                    }
                });
                break;
        }
    }
    mDrawerLayout.closeDrawer(GravityCompat.START);
    return true;

    }
}

现在我只是想删除已经添加的片段。

menuitem.xml

<item android:id="@+id/nav_switch"
            app:actionLayout="@layout/switch_menu"
            android:title="Send"
            android:icon="@drawable/ic_menu_send"/>

switch_menu switch_menu 是 switch 的布局。

switch_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v7.widget.SwitchCompat
        android:id="@+id/switch_id"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:text=""/>
</LinearLayout>

接入开关进入事件:--

SwitchCompat switch_id;

switch_id =  actionView.findViewById(R.id.switch_id);
        switch_id.setChecked(true);
        switch_id.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), switch_id.isChecked()? "is checked!!!" : "not checked!!!",Toast.LENGTH_SHORT).show();
            }
        });

使用上述代码的输出是:
