Android 如何将微调器添加为导航抽屉中的项目

我想在导航抽屉中添加微调器作为项目。我应该将微调器作为项目放在哪里？在哪里为微调器的布局充气？在哪里初始化微调器？我希望它看起来像这样：

这是我添加项目的地方：

<menu xmlns:android="http://schemas.android.com/apk/res/android">

<group
    android:id="@+id/group1"
    android:checkableBehavior="single">
    <item
        android:id="@+id/nav_login"
        android:icon="@drawable/ic_login"
        android:title="@string/login_menu_item"/>
    <item
        android:id="@+id/nav_signup"
        android:icon="@drawable/ic_signup"
        android:title="@string/signup_menu_item"/>
    </group>

<item android:title="@string/language">
    <menu>
        <item
            android:id="@+id/nav_eng"
            android:title="@string/english">
        </item>

        <item
            android:id="@+id/nav_heb"
            android:title="@string/hebrew">
        </item>
    </menu>

我将指导您如何在工具栏中制作自定义微调器，以便您可以从这里获得想法

步骤1添加支持库并创建工具栏布局

toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"
    android:minHeight="?attr/actionBarSize"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
     >

    <Spinner
        android:id="@+id/spinner_nav"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</android.support.v7.widget.Toolbar>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#c9c9c9"
    android:orientation="vertical" >

    <include
        android:id="@+id/toolbar"
        layout="@layout/spintoolbar" />


</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
   android:background="@drawable/spinner_selector"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tvCategory"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:textSize="18sp"
        />

</RelativeLayout>

<resources xmlns:android="http://schemas.android.com/apk/res/android">

<style name="AppTheme" parent="AppTheme.Base" />

<style name="AppTheme.Base" parent="Theme.AppCompat.NoActionBar">
    <!-- your app branding color for the app bar -->
    <item name="colorPrimary">@color/md_teal_500_primary</item>

    <!-- darker variant for the status bar and contextual app bars -->
    <item name="colorPrimaryDark">@color/md_teal_700</item>

    <!-- theme UI controls like checkboxes and text fields -->
    <item name="colorAccent">@color/md_teal_900</item>


</style>

第1步。请在menu.xml中添加项目

 <item
            android:id="@+id/navigation_drawer_item3"
            android:icon="@android:drawable/ic_menu_share"
            android:title=""
            app:actionLayout="@layout/spinner"/> 



第二步。请为微调器视图创建布局

<?xml version="1.0" encoding="utf-8"?>
<Spinner xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/spinner"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center_vertical"
    android:gravity="center_vertical" />



第三步。在活动文件中设置微调器数据

Spinner spinner = (Spinner) navigationView.getMenu().findItem(R.id.navigation_drawer_item3).getActionView();
    spinner.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,language));
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {  
          Toast.makeText(MainActivity.this,language[position],Toast.LENGTH_SHORT).show();
        }
        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });

Spinner-Spinner=（Spinner）navigationView.getMenu（）.findItem（R.id.navigation\u drawer\u item3.getActionView（）；
setAdapter（新的ArrayAdapter（这个，android.R.layout.simple_spinner_dropdown_item，language））；
spinner.setOnItemSelectedListener（新的AdapterView.OnItemSelectedListener（）{
@凌驾
已选择公共无效项（AdapterView父项、视图、整型位置、长id）{
Toast.makeText（MainActivity.this，语言[position]，Toast.LENGTH_SHORT.show（）；
}
@凌驾
未选择公共无效（AdapterView父级）{
}
});

第四步。如果需要，请将android支持设计库添加到项目中。
感谢您的努力，但我已经有了这个，几乎完全相同，而且功能也一样。：）现在，我如何才能将这种类型的微调器作为项目添加到导航抽屉中？与您添加到活动中的方式相同，我不能以我在活动中添加微调器的方式添加它，因为这次微调器需要位于导航视图中，而导航视图使用的是
app:menu=“@menu/activity\u home\u drawer”
。但我无法将旋转器作为一个项目添加。亲爱的@kapoor，目前它的工作方式与预期一致。但是，微调器仅与其中的文本一样大。是否有方法使其变大/变小？为微调器创建自定义行，并更改微调器导航视图的样式。getMenu（）不正确。
