您好，我尝试创建一个具有多渐变形状的可绘制 XML 文件。

我想要这样的东西，左上角是红色，右上角是黄色，底部是蓝色，如 3 个区域。 在此处输入图像描述

我能找到的最接近的事情是这里的其他问题。 多渐变形状 用户已通过使用修复它layer-list。我已经尝试过了，但这不起作用，我能理解的是我会这样做但不起作用。（这是button_real_world.xml文件）

<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android"
>
    <item>
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle"
        >
            <stroke android:width="4dp" android:color="#FFFF7700" /> 
            <padding android:left="7dp" android:top="7dp" 
                     android:right="7dp" android:bottom="7dp" /> 
            <corners android:radius="15dp" /> 

            <gradient
                android:angle="45"
                android:startColor="#FF63a34a"
                android:endColor="#FF477b36"
                android:type="linear"
                />    
        </shape>
    </item>
    <item>
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle"
        >
            <stroke android:width="4dp" android:color="#FFFF7700" /> 
            <padding android:left="7dp" android:top="7dp" 
                     android:right="7dp" android:bottom="7dp" /> 
            <corners android:radius="15dp" /> 
            <gradient
                android:angle="250"
                android:startColor="#FF63a34a"
                android:endColor="#ff477b36"
                android:type="linear"
                />    
        </shape>            
    </item>
</layer-list>

但这只会给我一个运行时错误，（在模拟器中运行，Windows）

尝试使用这个。提示：设置角度时，请使用 45 的倍数。
