**Android渐变GradientDrawable叠加组合环ring**

写一个Android环形shape之间的叠加组合形成新图像的例子。  
代码：

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item>
            <shape
                android:shape="ring"
                android:thickness="50dp"
                android:useLevel="false">
    
                <gradient
                    android:angle="0"
                    android:centerColor="@android:color/holo_orange_dark"
                    android:endColor="@android:color/holo_blue_dark"
                    android:startColor="@android:color/holo_red_dark" />
            </shape>
        </item>
    
        <item>
            <shape
                android:shape="ring"
                android:thickness="20dp"
                android:useLevel="false">
    
                <solid android:color="@android:color/holo_red_light" />
    
            </shape>
        </item>
    
        <item>
            <shape
                android:shape="ring"
                android:thickness="10dp"
                android:useLevel="false">
    
                <solid android:color="@android:color/holo_orange_light" />
    
            </shape>
        </item>
    
        <item>
            <shape
                android:shape="ring"
                android:thickness="2dp"
                android:useLevel="false">
    
                <solid android:color="@android:color/holo_blue_light" />
    
            </shape>
        </item>
    
    </layer-list>

结果：
