Change background of linearlayout in livecard

Question

I'm trying to change the color of a linearview when a certain state happens in my live card. I added the colors I want in my colors.xml and I'm able to set them in the live card layout itself.

but is there a way to set the background from code? I saw that there is no .setbackground or anything like this.

So is there a way to do this or would I need to go with images?

You can try to give the layout id in the xml and then:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (mLiveCard == null) {
        mLiveCard = new LiveCard(this, LIVE_CARD_TAG);

        RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.live_card);
        remoteViews.setInt(R.id.my_layout, "setBackgroundResource", android.R.color.holo_red_dark);            
        mLiveCard.setViews(remoteViews);

        // Display the options menu when the live card is tapped.
        Intent menuIntent = new Intent(this, LiveCardMenuActivity.class);
        mLiveCard.setAction(PendingIntent.getActivity(this, 0, menuIntent, 0));
        mLiveCard.publish(PublishMode.REVEAL);
    } else {
        mLiveCard.navigate();
    }
    return START_STICKY;
}

xml:

<LinearLayout
android:id="@+id/my_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="@dimen/card_margin"
tools:context=".LiveCardService">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />
</LinearLayout>
