带有渐变的Android形状边框

Question

我想为线性布局创建一个边框。所以我决定创建一个形状。我希望边框有渐变。以下不做。它填充矩形，然后创建一个笔触。我不想要一个填充的矩形，只是中风。我想将渐变应用到笔画。

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

    <gradient
        android:angle="360"
        android:centerColor="#e95a22"
        android:endColor="#ff00b5"
        android:gradientRadius="360"
        android:startColor="#006386"
        android:type="sweep" />

    <stroke
        android:width="2dp"
        android:color="#ff207d94" />

</shape>

试试这样的:

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

    <item>
        <shape android:shape="rectangle" >
            <gradient
                android:angle="360"
                android:centerColor="#e95a22"
                android:endColor="#ff00b5"
                android:gradientRadius="360"
                android:startColor="#006386"
                android:type="sweep" />

            <stroke
                android:width="2dp"
                android:color="#ff207d94" />
        </shape>
    </item>
    <item
        android:bottom="2dp"
        android:left="2dp"
        android:right="2dp"
        android:top="2dp">
        <shape android:shape="rectangle" >
            <solid android:color="#fff" />
        </shape>
    </item>

</layer-list>
