我在通知中工作,我有工具栏,我想显示两个菜单图标,即myicon\u clearnotifications和/myicon\u goback,但当我单击“仅通知”时,工具栏上没有显示这两个菜单项。我真的很累,要解决这个问题,我该怎么办。
xml工具栏代码
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorWhite"
tools:context="Activities.AllNotifications">
<androidx.appcompat.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/allNotifications_tollbar"
android:layout_alignParentTop="true"
android:background="#5A6E64"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
/>
<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:id="@+id/allNotifications_RecyclerView"/>
</RelativeLayout>
我的菜单项代码
<?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">
<item
android:id="@+id/allNotifications_item_clear"
android:title="CLEAR"
android:icon="@drawable/myicon_clearnotifications"
android:checkable="true"
app:showAsAction="always"
/>
<item
android:id="@+id/allNotifications_item_goBack"
android:title="GO BACK"
android:icon="@drawable/myicon_goback"
android:checkable="true"
app:showAsAction="always"
/>
</menu>
