推荐答案

okey，那么您需要手动创建图标菜单栏以对其进行完全控制.

okey then you need to create your icon menu bar manually to have full control on it.

首先在 activity.xml

<android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"                
            app:popupTheme="@style/AppTheme.PopupOverlay" >
            <!-- set any fixed size for 'width' but DO NOT set wrap_content-->
            <RelativeLayout
                android:layout_width="48dp"
                android:layout_height="wrap_content">

                <ImageView
                    android:id="@+id/icon_image_view"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="[YOUR ICON]"/>
                <!-- you can set any attributes you want (background-fixed position .. etc) 
                     and you can also remove alignParentBottom , alignParentEnd .. 
                     i just add it to be clear -->
                <TextView
                    android:id="@+id/notification_text_view"
                    android:layout_width="wrap_content"
                    android:layout_alignParentBottom="true"
                    android:layout_alignParentEnd="true"
                    android:layout_height="wrap_content" />

            </RelativeLayout>


        </android.support.v7.widget.Toolbar>

然后，如果您使用活动，则可以直接访问它们.如果您使用片段，则请执行以下步骤.

then you can access to them directly if you use activity .. if you use fragment then do these steps.

:为image_icon和text_notification添加设置器

in Fragment Class : add setter for both image_icon and text_notification

private ImageView iconImageView;
private TextView textNotificationView;


public void setIconImageView(ImageView iconImageView){
    this.iconImageView= iconImageView;
}
public void setTextNotificationView(TextView textNotificationView){
    this.textNotificationView= textNotificationView;
}

然后您需要手动设置片段. 在活动课程

then you need to set your fragment manually. In Activity Class

if(savedInstanceState == null) { // for rotation
        [FragmentClass] fragment = new [FragmentClass]();
        fragment.setIconImageView( (ImageView)findViewById(R.id.child_list_search_edit_view))
        fragment.setTextNotificationView( (TextView)findViewById(notification_text_view))

        getSupportFragmentManager().beginTransaction()
                .add(R.id.fragment, fragment, [Fragment TAG]).commit();
    }else{

        [FragmentClass] childActivityFragment =([FragmentClass]) getSupportFragmentManager()
                .findFragmentByTag([Fragment TAG]);

        fragment.setIconImageView( (ImageView)findViewById(R.id.child_list_search_edit_view))
        fragment.setTextNotificationView( (TextView)findViewById(notification_text_view))

    }

现在，您可以根据需要添加通知.

Now you can add your notifications as you want.
