Different text for the wear device and the mobile device

问题

Is it possible to have a notification that shows a different text (content title and content text) in the Android wear device and in the mobile device?

回答1:

Not at the moment. However, you can achieve this effect in the following way:

post a notification on the phone with setLocalOnly(true)
post a DataItem using a DataAPI that describes the notification and changed text
when the wearable receives the DataItem, post the notification with different text, again setting setLocalOnly(true)
on each notification alse call setDeleteIntent so you know, when there are dismissed
when on of the notifications gets dismissed, delte the DataItem from point 2.
when the DataItem gets deleted, you will receive a callback; delete the remaining notification

There might be some corner cases here I don't see immediately, but the general approach should allow you to achieve what you want.

Yes, it's possible now with little tricky and bug on Android wear which help's us. More Over this trick doesn't need Android wear API, just a normal Notification with RemoteViews is enough.

NotificationCompat.Builder mBuilder;
    mBuilder = new NotificationCompat.Builder(context)
    .setSmallIcon(R.drawable.ic_launcher)
    .setAutoCancel(true)
    .setContentText("This msg won't display in your phone, only on wear you can see.")
    .setContentTitle("Hello")

    .setContentIntent(
            PendingIntent.getActivity(context, 10,intent,PendingIntent.FLAG_ONE_SHOT));

    NotificationManager mNM = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = mBuilder.build();

    RemoteViews contentView = new RemoteViews(context.getPackageName(),
    R.layout.notification_layout);

    contentView.setTextViewText(R.id.noti_text,"This message won't display in your wear device, only on phone you can see.");
    contentView.setImageViewResource(R.id.noti_image,R.drawable.ic_launcher);
    notification.contentView = contentView;

    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    mNM.notify(50, notification);

Now run the app on your device and check the notification on both watch and phone, the content inside the RemoteViews won't display in your watch but on phone it will display and if you remove the .setContentTitle() & .setContentText(), then the RemoteViews content will be displayed on both watch and phone too.
