导航视图+选择器+涟漪效果状态选择不起作用

Question

我搜索了所有的东西并进行了实验,但没有运气NavigationView.

itemIconTint,itemTextColor并itemBackground有效地工作ripple.但问题state selected不起作用selector drawable

我也创造drawable-v21并投入ripple_navigation_selector.xml

我的目标是当再次打开抽屉时,之前选择的项目应为黄色,例如.通知项目

NavigationView 在main_layout.xml中

  <android.support.design.widget.NavigationView
    android:id="@+id/navigation_view"
    android:layout_width="250dp"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    android:background="@color/black"
    app:headerLayout="@layout/header"
    app:itemIconTint="@drawable/navigation_view_icon_tint_selector"
    app:itemTextColor="@drawable/navigation_view_text_selector"
    app:menu="@menu/drawer"
    app1:itemBackground="@drawable/ripple_navigation_selector"
     />

ripple_navigation_selector.xml 内 drawable-v21

<item
    android:id="@android:id/mask"
    android:drawable="@drawable/navigation_selector"/>
<item android:drawable="@drawable/navigation_selector"/>

navigation_selector.xml 内 drawable-v21

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

颜色字符串命名 left_light_yellow

<color name="left_light_yellow">#F6CE20</color>

我认为你必须让你的菜单项可检查

<item
        android:id="@+id/wishlist"
        android:checkable="true"
        android:title="Wishlist" />
