android - 在 Android Wear 上设置背景

Question

我正在尝试为 Android Wear 上的通知设置背景，但出现错误

setBackground in android.support.v4.app.NotificationCompat.WearableExtender cannot be applied to (int)

我已经尝试了一段时间，但我被难住了。

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("Code Received")
            .setContentText("Your Orange Wednesday code is " + orangeCode)
            .extend(new NotificationCompat.WearableExtender().setBackground(R.drawable.orangebg));

如果有人能够指出我正确的方向，那将不胜感激。谢谢

Answer 1

如文档中所示，该方法需要位图作为输入。

https://developer.android.com/reference/android/support/v4/app/NotificationCompat.WearableExtender.html#setBackground(android.graphics.Bitmap)

public NotificationCompat.WearableExtender setBackground (Bitmap background)

Set a background image to be displayed behind the notification content. Contrary to the NotificationCompat.BigPictureStyle, this background will work with any notification style.

Parameters

background - the background bitmap

R.drawable.XXX 是框架用于查找您的实物 Assets 的整数标识符。使用 BitmapFactory.decodeResource(context.getResources(), R.drawable.XXX) 从您的 Assets 中检索位图并稍后应用。
