代碼，我是充氣

<?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/inflating_comment_menu" 
    android:actionLayout="@layout/new_comment_menu" 
    android:title="" 
    app:showAsAction="always" /> 
</menu> 

是在動作設計上使用

和佈局是

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

Answer 1

您應該使用app:actionLayout="@layout/inflating_comment_menu"代替android:actionLayout="@layout/inflating_comment_menu"
