在android中的语音泡沫

Question

您好我想用语音气泡作为我的应用的背景图片。我在这里发布了这个

Android drawable speech bubble

这个例子从正确的方向开始，我想在我试过的相反方向实现这个目标

    <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:top="30dp">
        <rotate
            android:fromDegrees="-45"
            android:pivotX="0%"
            android:pivotY="0%"
            android:toDegrees="0" >
            <shape android:shape="rectangle" >
                <solid android:color="#CCC" />
            </shape>
        </rotate>
    </item>
    <item android:right="10dp">
        <shape android:shape="rectangle" >
            <solid android:color="#CCC" />

            <corners android:radius="5dp" />
        </shape>
    </item>

</layer-list>

但我无法让它发挥作用，我们将非常感谢任何帮助！
