Question

在我的导航栏中，我的列表视图图标如下所示check image。所以这意味着我已经在后台施加了图标。

我知道通过Frame Layout，我可以将图标放在图像上，但我很困惑，当它在res/menu文件夹中声明时我怎么能这样做

menu.xml文件

    <menu xmlns:android="http://schemas.android.com/apk/res/android">
    <group android:checkableBehavior="single">
           <item
            android:id="@+id/nav_home"
            android:icon="@drawable/ic_home_white_24dp"
            android:title="@string/nav_item_home" />

        <item
            android:id="@+id/appointment_history"
            android:icon="@drawable/appointment_icon"
            android:title="@string/nav_history" />
        <item
            android:id="@+id/contact_us"
            android:icon="@drawable/contact_us_icon"
            android:title="@string/nav_contact_us" />

        <item
            android:id="@+id/nav_settings"
            android:icon="@drawable/setting_icon"
            android:title="@string/nav_setting" />
    </group>
</menu>

Answer 1

首先，您需要将图标色调设置为空。

navigationView.setItemIconTintList(null);

然后你可以像这样创建一个xml drawable，在这个例子中我将它命名为rounded_corner_home。

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item >
    <shape android:shape="rectangle">
        <solid android:color="#007f12" />
        <corners android:radius="4dp" />
    </shape>
    </item>
    <item>
        <bitmap android:src="@drawable/ic_home_white_24dp"/>
    </item>
</layer-list>

然后更改菜单项的图标适用性。

<item
    android:id="@+id/nav_home"
    android:icon="@drawable/rounded_corner_home"
    android:title="@string/nav_item_home" />

结果截图：Screen

Using this code you can change the color of drawer icon : 

o NavigationView (it is located in activity_main.xml layout file) The default tint is black but you can use an even darker shade of black by using #000000

 <android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_main"
    app:itemIconTint="#000000"
    app:menu="@menu/activity_main_drawer" />

设置导航抽屉图标的背景
