我看不到 Android Wear 模拟器的背景

Question

我的问题是我在 Android Wear 模拟器中看不到背景，我用经过验证的图像声明 .setBackgroung 但是当我运行应用程序并向我发送通知时背景不显示。

有什么帮助吗？

public class NotificationService extends FirebaseMessagingService {
    public static final String TAG = "FIREBASE";
    public static final int NOTIFICATION_ID = 001;
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //super.onMessageReceived(remoteMessage);
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        enviarNotificacion(remoteMessage);
    }

    public void enviarNotificacion(RemoteMessage remoteMessage){
        Intent i = new Intent();
        i.setAction("TOQUE_ANIMAL");
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
        Uri sonido = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Action action =
                new NotificationCompat.Action.Builder(R.drawable.ic_full_poke,
                        getString(R.string.texto_accion_toque), pendingIntent)
                .build();

        NotificationCompat.WearableExtender wearableExtender =
                new NotificationCompat.WearableExtender()
                .setHintHideIcon(true)
                .setBackground(BitmapFactory.decodeResource(getResources(),
                        R.drawable.bk_androidwear_notification))
                .setGravity(Gravity.CENTER_VERTICAL);

        NotificationCompat.Builder notificacion = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notificacion)
                .setContentTitle("Notificacion")
                .setContentText(remoteMessage.getNotification().getBody())
                .setAutoCancel(true)
                .setSound(sonido)
                .setContentIntent(pendingIntent)
                .extend(wearableExtender.addAction(action))
                //.addAction(R.drawable.ic_full_poke, getString(R.string.texto_accion_toque), pendingIntent)
                ;

        NotificationManagerCompat notificationManager =
                NotificationManagerCompat.from(this);
        notificationManager.notify(NOTIFICATION_ID, notificacion.build());
    }
}

您可以参考此 SO post. Try to use setBackground(Bitmap) method from WearableExtender instead of setLargeIcon(Bitmap). You may also check this tutorial 如何为 Android Wear 创建表盘。

为 Android Wear 通知设置背景图片的额外参考：Background image for android wear notification

The resolution for square watch faces as of right now is 280x280, whereas the circular watch face has a resolution of 320x320 (although some of this will be cut off, obviously).

However, Android Wear implements a sort of parallax scrolling by default for larger images, so it can handle larger images with great ease, and it is even recommended that you do so (see this previous answer). So you really shouldn't worry about the size of the image, unless you were trying to create a static, full-screen image with specific areas of interaction as a substitute for custom UI elements (which you can do, I might add, although Google recommends you have only one area of interaction per screen on the watch to keep things simple).

If you want to see a good example of multiple images being used for backgrounds with parallax scrolling, I recommend you check out the GridViewPager sample project, which can be found in the SDK samples in the wearable subfolder for API level 20.

希望对您有所帮助！
