android - NavigationView:使用 app:actionLayout 自定义项目布局如何？

Question

根据最近的 Ian Lake 帖子

And if you haven't looked at NavigationView recently, it actually got quite an update in version 23.1.0 [1] with the addition of app:actionLayout support for custom view support.

如何在 NavigationView 中使用 app:actionLayout？

使用

<group android:checkableBehavior="single">
    <item
        android:id="@+id/navigation_drawer_item_1"
        android:icon="@drawable/ic_menu_1"
        android:title="@string/navigation_drawer_item_1"
        app:actionLayout="@layout/menu_test_1"
        />
    <item
        android:id="@+id/navigation_drawer_item_2"
        android:icon="@drawable/ic_menu_2"
        android:title="@string/navigation_drawer_item_2"
        app:actionLayout="@layout/menu_test_1"
        />
</group>

与

<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:menu="@menu/activity_main_drawer">

这是行不通的。它在项目的右侧显示 actionLayout。同时删除 android:icon 和 android:title 似乎不起作用。

我该如何解决？

谢谢问候

我通过从 android:title 中删除任何文本来解决这个问题。

导航 View :

<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:menu="@menu/activity_main_drawer" />

菜单代码(activity_main_drawer):

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

    <group android:checkableBehavior="single">
        <item android:id="@+id/nav_item1"
            app:showAsAction="always"
            android:title=""
            app:actionLayout="@layout/menu_item_layout" />
    </group>
</menu>

菜单项布局:

<?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="match_parent">

    <TextView android:id="@+id/item_text"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_vertical"
        android:text="Item text" />
</RelativeLayout>
