android - 如何将 RelativeLayout 添加为菜单项 - Android

Question

我有一个带有 item 和 group 的菜单 XML。我打算在 XML 中添加一个 RelativeLayout 作为菜单项，这样它看起来像:

<menu>
    <item1/>
    <item2
         <RelativeLayout>
               <TextView1/>
               <TextView2/>
         <RelativeLayout>
    />
</menu>

这可以在布局 XML 中完成，还是以编程方式完成？如果没有，解决方法会有所帮助。谢谢。

用你想要的 View 创建一个布局文件，然后像这样使用它 -

<item
    android:id="@+id/menu_refresh"
    android:title="@string/refresh"
    yourapp:showAsAction="never"
    android:actionLayout="@layout/my_custom_layout"/>

编辑 TextView -

@Override
public boolean onPrepareOptionsMenu(Menu menu) {

    //Get a reference to your item by id
    MenuItem item = menu.findItem(R.id.menu_refresh);

    //Here, you get access to the view of your item, in this case, the layout of the item has a RelativeLayout as root view but you can change it to whatever you use
    RelativeLayout rootView = (RelativeLayout)item.getActionView();

    //Then you access to your control by finding it in the rootView
    TextView textview1 = (TextView) rootView.findViewById(R.id.text1);

    //And from here you can do whatever you want with your text view

    return true;
}
