在res文件夾下創(chuàng)建一個menu的文件夾，里面放navigation.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/navigation_message"
        android:icon="@drawable/unselect_message"
        android:title="@string/tv_message" />
    <item
        android:id="@+id/navigation_friends"
        android:icon="@drawable/unselect_friends"
        android:title="@string/tv_friend" />
    <item
        android:id="@+id/navigation_mine"
        android:icon="@drawable/unselect_mine"
        android:title="@string/tv_mine" />
</menu>

在drawable創(chuàng)建color_navigation_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/deepskyblue" android:state_checked="true" />
    <item android:color="@color/gainsboro" android:state_checked="false" />
</selector>
