我需要在选项菜单中显示布局。

menu.xml文件 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/action_likes"
        android:showAsAction="never"
        android:actionLayout="@layout/likes_layout"/>

    <item
        android:id="@+id/settings"
        android:showAsAction="never"
        android:title="Settings"
        />
</menu>

shape_notification.xml 

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <stroke android:color="#080808" android:width="2dp"/>
    <corners android:radius="5dp" />
    <solid android:color="#85ea32"/>
</shape>

likes_layout.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="3"
        android:id="@+id/likes"
        android:linksClickable="false"
        android:text="Likes"
        android:gravity="center_vertical|center_horizontal"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="5"
        android:layout_gravity="center"
        android:id="@+id/notif_count"
        android:background="@drawable/shape_notification"
        android:text="0"
        android:textSize="16sp"
        android:gravity="center"
        android:padding="2dp"
        android:singleLine="true"
        android:layout_margin="5dp"
        android:textColor="#fff"/>
</LinearLayout>

MainActivity.java 

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);

        return true;
    }
}

选项列表可见。设置项目可见但喜欢布局为空白。

是否有人为隐藏物品做过动作布局？请帮帮我

将android:actionLayout更改为app:actionLayout，以便您的菜单项声明应为

  <item
    android:id="@+id/action_likes"
    app:showAsAction="never"
    app:actionLayout="@layout/likes_layout"/>

已更新：

您必须使用PopupWindow创建自定义下拉菜单。需要实现以存档它的代码：

menu.xml文件 

<menu 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"
tools:context="project.com.example.MainActivity"

>
<item
    android:id="@+id/item1"
    android:title="@string/action_settings"
    android:icon="@drawable/ic_launcher"
    app:actionViewClass="android.widget.ImageButton"
    app:showAsAction="always">

<menu>
</menu>
</item>

</menu>

MainActivity.java 

   @Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    locButton = (ImageButton) menu.findItem(R.id.action_settings).getActionView();
    locButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            PopupWindow popupwindow_obj = popupDisplay();
            popupwindow_obj.showAsDropDown(locButton, -40, 18);
        }
    });
    return true;
}
  public PopupWindow popupDisplay()
{

    final PopupWindow popupWindow = new PopupWindow(this);

    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View view = inflater.inflate(R.layout.listViewLayout, null);
    ListView listView=(ListView)view.findViewById(R.id.list);
    // populate listview with custom view which will be shown in drow down menu 
    popupWindow.setFocusable(true);
    popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
    popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
    popupWindow.setContentView(view);

    return popupWindow;
}

希望它有所帮助。

可以使用 自定义弹出窗口 来完成。
