java 安卓在一个布局上有多个AddView，其中一个xml可绘制

Question

我试图在布局上获得一个可绘制形状的多个副本，但每次都要更改颜色。我不知道第二个imageview是否刚好落在第一个imageview的顶部。我无法将它们放置在不同的位置以进一步排除故障。每个实例都需要自己的参数吗

@drawable/circle（circle.xml）

<shape
xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
安卓:shape="oval">

<solid
    安卓:color="#FF888888"/>

<size
    安卓:width="60dp"
    安卓:height="60dp"/>
</shape>

主要活动。xml

<RelativeLayout xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
xmlns:tools="http://schemas.安卓.com/tools"    
安卓:layout_width="match_parent"
安卓:layout_height="match_parent" 
安卓:paddingLeft="@dimen/activity_horizontal_margin"
安卓:paddingRight="@dimen/activity_horizontal_margin"
安卓:paddingTop="@dimen/activity_vertical_margin"
安卓:paddingBottom="@dimen/activity_vertical_margin" 
tools:context=".MainActivity"
安卓:id="@+id/root">

</RelativeLayout>
