如何在android中创建发光背景？

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient
        android:type="radial"
        android:centerColor="#00FFFFFF"
        android:endColor="#FF00FF00"
        android:gradientRadius="200"
        android:angle="0" />
    <solid android:color="#00000000" />
    <corners android:radius="100dp" />
    <stroke
        android:color="#FF00FF00"
        android:width="2dp"
        android:dashWidth="5dp"
        android:dashGap="5dp" />
</shape>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/glowing_background">
    <!-- 其他视图组件 -->
</LinearLayout>
