Changing notification icon background on Lollipop
AndroidAndroid NotificationsAndroid 5.0-LollipopAndroid Problem Overview
I was going through the Notifications design pattern, and didn't find anything that talks about notification icon background. As you probably noticed, there is only a light grey background for custom notifications. But apps like Hangouts, or simply the USB Debugging notification has a custom color for their notification icon background.
Is there any possibility to change that grey into something else? (that specific circle's color programmatically)
Android Solutions
Solution 1 - Android
###1) Obtain Color
int color = 0xff123456;
int color = getResources().getColor(R.color.my_notif_color);
int color = ContextCompat.getColor(context, R.color.my_notif_color);
###2) Set the Color to the Notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
...
builder.setColor(color);
Notification notif = builder.build();
The color is respected only on Lollipop and only affects background of the small icon. If a large icon is shown its contents are entirely your responsibility.
Solution 2 - Android
if you've defined color in colors.xml then in your NotificationBuilder add value as
.setColor(getResources().getColor(R.color.<YOUR_COLOR>))
That should solve your problem. It only affect to background of the icon.
Solution 3 - Android
getColor(int)
has been deprecated on Resources
We should now use one of these alternatives:
Resources
's getColor(int, Theme)ContextCompat
's getColor(Context context, int id)
