I've a problem changing my Background-Color with the Application-Theme.
NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this);
TypedValue typedValue = new TypedValue();
getTheme().resolveAttribute(R.attr.colorPrimary, typedValue, true);
int iPrimaryColor = typedValue.data;
getTheme().resolveAttribute(R.attr.colorPrimaryDark, typedValue, true);
int iPrimaryDarkColor = typedValue.data;
Intent notIntent = new Intent(getApplicationContext(), MainActivity.class);
notIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent notOpenOnClick = PendingIntent.getActivity(getApplicationContext(), 0, notIntent, PendingIntent.FLAG_UPDATE_CURRENT);
RemoteViews smallContentView = new RemoteViews(getPackageName(), R.layout.notification_small);
RemoteViews bigContentView = new RemoteViews(getPackageName(), R.layout.notification_expanded);
nBuilder.setSmallIcon(R.drawable.not_icon)
.setOngoing(true)
.setContentTitle(getCurrentSong().getTitle())
.setContentIntent(notOpenOnClick);
Notification not = nBuilder.build();
smallContentView.setInt(R.id.not_linLayout, "setBackgroundColor", iPrimaryColor);
smallContentView.setInt(R.id.not_imvDivider, "setBackgroundColor", iPrimaryDarkColor);
bigContentView.setInt(R.id.not_linLayout, "setBackgroundColor", iPrimaryColor);
bigContentView.setInt(R.id.not_imvDivider, "setBackgroundColor", iPrimaryDarkColor);
setListeners(smallContentView);
setListeners(bigContentView);
not.contentView = smallContentView;
not.bigContentView = bigContentView;
if (isPlaying()) {
not.contentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_pause_48dp);
not.bigContentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_pause_48dp);
}
else {
not.contentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_play_48dp);
not.bigContentView.setImageViewResource(R.id.not_btnPlayPause, R.drawable.ic_play_48dp);
}
I already tried this, but the Background of my Notification is still white. The ID's are correct, the View linLayout is a LinearLayout.
Please keep in mind: The whole codes is invoked in a Service!
Thanks!
Much of this can be easier done by taking advantage of NotificationCompat.MediaStyle. It pulls the background color from the setColor() call on pre-API 24 devices (and uses that color as an accent on API 24+ devices). This also means you don't need to write any custom RemoteViews code anymore as it relies solely on the actions you add to your notification for media controls:
NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this);
nBuilder.setSmallIcon(R.drawable.not_icon)
.setContentTitle(getCurrentSong().getTitle())
.setContentIntent(notOpenOnClick);
// This is what sets the background color on <N devices
// It is an accent color on N+ devices
nBuilder.setColor(getResources().getColor(R.color.colorPrimary));
// Add actions via nBuilder.addAction()
// Set the style, setShowActionsInCompactView(0) means the first
// action you've added will be shown the non-expanded view
nBuilder.setStyle(new NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0));
You should definitely read over all of the methods available for MediaStyle and reivew the Best Practices in media playback I/O 2016 talk for example code and best practices around using notifications. Specifically at 30 minutes into the talk
