将TextView添加到工具栏的元素

问题描述:

我制作了一个材质设计工具栏.菜单项包括一个购物车.我希望在显示购物车图标的同时显示一个数字,以指示购物车中存在的物品数量.

I have made a material design toolbar. The menu item includes a cart. I want a number to be shown along with the cart icon indicating the number of items present in the cart.

toolbar.xml

toolbar.xml

 <?xml version="1.0" encoding="utf-8"?>
 <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Light"
android:id="@+id/tool_bar"
android:elevation="6dp">

menu_cart.xml

menu_cart.xml

<?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/action_cart" android:icon="@drawable/bag"
    android:title="Cart"
    android:orderInCategory="100" app:showAsAction="always" />
    </menu>

也许在购物车图标顶部应该可以看到该文本视图.不能作为购物车图标旁边的文本视图.

The textview should be visible on top of the cart icon hiding it a bit,maybe. Not as a textview beside the cart icon.

            android:src="@drawable/bag"
            android:layout_alignParentLeft="true"
            android:layout_centerInParent="true"></ImageView>

        <ImageView
            android:id="@+id/arrow"
            android:layout_width="48dp"
            android:layout_height="wrap_content"
            android:src="@drawable/usability_bidirectionality_guidelines_when3"
            android:layout_alignParentRight="true"></ImageView>

        <ImageView
            android:id="@+id/number"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:src="@drawable/one"
            android:layout_alignTop="@+id/shopping_bag"
            android:layout_alignRight="@+id/shopping_bag"/>

    </RelativeLayout>

它看起来像:
