为Android组设置不同的背景-Android

我想要一些菜单项有不同的背景。例如，我希望nav_hesabim的背景为红色。我希望导航用户在背景中是黄色的。所以我想使用不同颜色的菜单项背景。我正在使用NavigationView。我该怎么做

活动\u main 2\u抽屉

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

    <group android:checkableBehavior="single"
        android:id="@+id/group1">
        <item
            android:id="@+id/nav_hesabim"
            android:icon="@mipmap/avatar"
            android:title="@string/menu_hesabim" />

    </group>

    <group android:checkableBehavior="single"
        android:id="@+id/groupsss">
    <item
            android:id="@+id/nav_usersss"
            android:icon="@mipmap/sss3"

            android:title="@string/menu_userSss" />
    </group>
</menu>

下面的代码对我来说很好 我的导航视图：-

<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"
    android:background="@color/nav.background"
    app:menu="@menu/menu_drawer"
    app:itemBackground="@drawable/nav_item_background"
    app:itemTextColor="@drawable/nav_item_text"/>

可绘制/nav_item_background.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true" android:drawable="@color/nav.item.background" />
  <item android:state_checked="true" android:drawable="@color/nav.item.background" />
  <item android:state_focused="true" android:drawable="@color/nav.item.background" />
  <item android:state_activated="true" android:drawable="@color/nav.item.background" />
  <item android:drawable="@color/nav.item.background.default" />
</selector>

可绘制/nav_item_text.xml

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

谢谢。

我不想在选择菜单项时改变背景。我希望group1的背景菜单是红色的，groupsss是黄色的。我想用不同的背景，所以你必须用这种方式。查看以下链接：-

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true" android:drawable="@color/nav.item.background" />
  <item android:state_checked="true" android:drawable="@color/nav.item.background" />
  <item android:state_focused="true" android:drawable="@color/nav.item.background" />
  <item android:state_activated="true" android:drawable="@color/nav.item.background" />
  <item android:drawable="@color/nav.item.background.default" />
</selector>

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