android - Notification Builder setSmallIcon "background"颜色

Question

我正在处理通知。我会使用下面的代码设置通知图标，但无法设置图标的背景颜色(突出显示的圆形紫色)。如果有人愿意分享这个方法，那就太好了。

    notificationBuilder.setContentTitle(title);
    notificationBuilder.setContentText(summaryText);      
    notificationBuilder.setSmallIcon(R.drawable.icon);
    notificationBuilder.setContentIntent(clickIntent);
    notificationBuilder.setDeleteIntent(deleteIntent);

[后续]嗯……我已经尝试了帖子中建议的方法，但是……图标的背景颜色仍然是“白色”......我不会设置颜色...

You can probably create drawable to set icon background and set that as icon 

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="@dimen/margin_10dp" android:left="@dimen/margin_10dp" android:top="@dimen/margin_10dp" android:bottom="@dimen/margin_10dp">
    <shape android:shape="rectangle">
        <solid android:color="@color/purple"/>
        <padding android:bottom="@dimen/margin_10dp" android:right="@dimen/margin_10dp" android:left="@dimen/margin_10dp" android:top="@dimen/margin_10dp"/>
    </shape>
</item>
    <item android:drawable="@mipmap/logo" >
    </item>

</layer-list>
