как убрать переключатель на домашнем экране?

Question

Так что в настоящее время мой домашний экран выглядит так:

! [Введите описание изображения здесь] [1]

однако, хотя в моем навигационном ящике у меня уже есть переключатель, созданный внутри. Следовательно, поэтому я хотел бы спросить, есть ли способ гарантировать, что единственным переключателем, который у меня будет, будет тот, который находится внутри моего навигационного ящика?

, вот мой layout_switch.xml файл

<?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">

    <Switch
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:id="@+id/btnSwitch"/>

</LinearLayout>

вот мой drawable_menu файл

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/signIn"
        android:icon="@drawable/ic_account_circle_black_24dp"
        android:title="Sign In" />
    <item
        android:id="@+id/Mode"
        app:actionLayout="@layout/layout_switch"
        android:icon="@drawable/ic_brightness_4_black_24dp"
        android:title="Dark Mode" />

</menu>

, а это мой activity_main файл

<?xml version="1.0" encoding="utf-8"?>

* Обновлено , так что теперь, очевидно, я смог получить возможность переключения переключите его в темный режим после внесения некоторых корректировок в мою функцию MainActivity, но, тем не менее, хотя этот переключатель может работать именно тот, который вы видите в ss, но не тот, который есть в моем навигационном ящике. Почему?

Answer 1

Чтобы решить проблему перекрытия новостей на панели инструментов, замените панель инструментов xml на приведенный ниже код. Если решено, примите и этот ответ, пожалуйста.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

<androidx.appcompat.widget.Toolbar
    android:id="@+id/toolbar_top"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="@color/action_bar_bkgnd"
    app:theme="@style/ToolBarTheme" >


     <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Toolbar Title"
        android:layout_gravity="center"
        android:id="@+id/toolbar_title" />

    </androidx.appcompat.widget.Toolbar>

</LinearLayout>

Answer 2

Сначала удалите переключатель из макета Activity_main

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
       >


        <Switch
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/btnSwitch"
            android:text=""/>



    </LinearLayout>

Затем добавьте это в MainActivity и настройте то, что вам нужно. Это точно сработает. Я проверил

Menu menu = navigationView.getMenu();
MenuItem menuItem = menu.findItem(R.id.btnSwitch);
View actionView = MenuItemCompat.getActionView(menuItem);
actionView.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

  }
});
