大佬教程收集整理的这篇文章主要介绍了android – 如何在AppCompatActivity中显示图标和文本的菜单项，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我在xml文件中尝试了不同的组合：

<menu xmlns:android="http://scheR_106_11845@as.android.com/apk/res/android"
    xmlns:app="http://scheR_106_11845@as.android.com/apk/res-auto"
    xmlns:tools="http://scheR_106_11845@as.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_create_alarm"
        android:icon="@drawable/ic_action_accept"
        android:orderInCategory="100"
        android@R_261_6964@="@String/menu_create_alarm"
        app:showAsAction="ifRoom|withText" />
</menu>

要么

<menu xmlns:android="http://scheR_106_11845@as.android.com/apk/res/android"
    xmlns:app="http://scheR_106_11845@as.android.com/apk/res-auto"
    xmlns:tools="http://scheR_106_11845@as.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_create_alarm"
        android:icon="@drawable/ic_action_accept"
        android:orderInCategory="100"
        android@R_261_6964@="@String/menu_create_alarm"
        app:showAsAction="always|withText" />
</menu>

要么

<menu xmlns:android="http://scheR_106_11845@as.android.com/apk/res/android"
    xmlns:app="http://scheR_106_11845@as.android.com/apk/res-auto"
    xmlns:tools="http://scheR_106_11845@as.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_create_alarm"
        android:icon="@drawable/ic_action_accept"
        android:orderInCategory="100"
        android@R_261_6964@="@String/menu_create_alarm"
        app:showAsAction="withText" />
</menu>

要么

<menu xmlns:android="http://scheR_106_11845@as.android.com/apk/res/android"
    xmlns:app="http://scheR_106_11845@as.android.com/apk/res-auto"
    xmlns:tools="http://scheR_106_11845@as.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_create_alarm"
        android:icon="@drawable/ic_action_accept"
        android:orderInCategory="100"
        android@R_261_6964@="@String/menu_create_alarm"
        android:showAsAction="always|withText" />
</menu>

我试图用编程方式设置它

@Override
    public void onCreateOptionsMenu(Menu menu,MenuInflater inflater){
        MenuItem item = menu.add(R.String.menu_create_alarm);
        item.setShowAsAction(MenuItem.SHOW_AS_ACTION_WITH_TEXT|MenuItem.SHOW_AS_ACTION_IF_ROOM);
        item.setIcon(R.drawable.ic_action_accept);
        item.setOnMenuItemClickListener(
            new OnMenuItemClickListener(){

                @Override
                public Boolean onMenuItemClick(MenuItem item){
                    saveAlarm();
                    return true;
                }
            }
        );


//      inflater.inflate(R.menu.menu_create_alarm,menu);
        super.onCreateOptionsMenu(menu,inflater);

    }

要么

<menu xmlns:android="http://scheR_106_11845@as.android.com/apk/res/android"
    xmlns:app="http://scheR_106_11845@as.android.com/apk/res-auto"
    xmlns:tools="http://scheR_106_11845@as.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_create_alarm"
        android:icon="@drawable/ic_action_accept"
        android:orderInCategory="100"
        android@R_261_6964@="@String/menu_create_alarm"
        android:showAsAction="always|withText"
        app:showAsAction="always|withText" />
</menu>

但是,仅显示图标.并且有植物的房间,因为我没有设置工具栏标题.删除菜单并用工具栏中的按钮来替换它们不是可切换的.
如何显示文字？

解决方法

你需要添加工具：context =“你的类”到菜单标签

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://scheR_106_11845@as.android.com/apk/res/android"
   xmlns:app="http://scheR_106_11845@as.android.com/apk/res-auto"
   xmlns:tools="http://scheR_106_11845@as.android.com/tools"
   tools:context=".activities.baseActivity">


   <item
       android:id="@+id/action_notification1"
       android:icon="@drawable/three"
       android@R_261_6964@="action_notification"
       app:showAsAction="always">
       <menu>
           <item
               android:id="@+id/profile"
               android:icon="@drawable/profile"
               android:orderInCategory="100"
               android@R_261_6964@="PROFILE" />

           <item
               android:id="@+id/c"
               android:icon="@drawable/correct_tick"
               android:orderInCategory="100"
               android@R_261_6964@="COMPLETED TRIPS" />

           <item
               android:id="@+id/app"
               android:icon="@drawable/report_issue"
               android:orderInCategory="100"
               android@R_261_6964@="REPORT ISSUES" />
           <item
               android:id="@+id/r"
               android:icon="@drawable/correct_tick"
               android:orderInCategory="100"
               android@R_261_6964@="REACHED CENTER" />


           <item
               android:id="@+id/pdf"
               android:icon="@drawable/pdf_image"
               android:orderInCategory="100"
               android@R_261_6964@="BAG INFO" />
           <item
               android:id="@+id/l"
               android:icon="@drawable/logout"
               android:orderInCategory="100"
               android@R_261_6964@="logoUT" />
       </menu>
   </item>


</menu>



     @Override 
         public Boolean onCreateOptionsMenu(Menu menu) {

         getMenuInflater().inflate(R.menu.main,menu); 
         menu.getItem(0).getSubMenu().getItem(3).setVisible(false);
         menu.getItem(0).getSubMenu().getItem(4).setVisible(true);
         return super.onCreateOptionsMenu(menu);

         }
