How to change the text colour of Android Notification

We are using Foreground Service with Notification. A very simple use-case requires us to change the text-colour of the notification's body and title text. After a quick search, I was enlighten with setColor() method of NotificationCompat.Builder.
However, using it only changes the tint colour of the small icon and not the notification title or body text. I also wanted the text 0/7 files have been uploaded and 7 pending to be coloured desirably. This is how it looks currently,
How can I change the text colour of the notification title and body text?

you can't change this, this is system style for Notification, don't have option for setting text color... but you can introduce your own layout for this purpose, but be aware that across different Android distributions there are different default Notification styles (made by manufacturers) and you won't provide one universal style with only-text-color-changed style, which will fit into system styling (same look as other notifications)

android notification background color is not white on lollipop

As we known that Android lollipop force set the notification background color to white, so we can set the style of TextView according to different sdk version by putting style.xml in folder values-v21.
So here comes my question, on some third party ROMs, for example, the EMUI developed by Huawei tech co., the background of notification is not white(nearly black), by setting style to
android:TextAppearance.Material.Notification.Title
the color of the text is almost black, as a result, we cannot see the text clearly. I had been searching the internet for almost two days but find nothing helps.
I am trying to get the color of the notification background and set the text color dynamically, but I don't know how to accomplish this.
Need your help, thanks a lot.

Ok, so I just use the official API to set the notification info, that would inflate the default notification layout (status_bar_latest_event_content.xml）instead of my custom layout.
The rom changed the default background and text-color of the status_bar_latest_event_content.xml, but it wouldn't (or can't) change the custom layout.
mBuilder.setLargeIcon(combineBitmap).setContentText(notifyString).setSubText("fff");

remove the android:targetSdkVersion="21" from manifest.xml. it will work! and from this there is no prob at all in your apk it just a trick i apply this and i found colorful icon in notification and all features will remain same which u earlier use

Normal view Android Notification with Buttons

I read that we can add buttons to the Big view of notifications that is available from 4.1. I want the same layout with buttons in 4.0. I want to know if I use custom view for notification containing the buttons, Will that work in 4.0 ?
Thanks.

The notifications before 4.1 were limited which is why Big View notifications were introduced in 4.1
It isn't possible to have custom views before 4.1 unfortunately
One of the reasons for this is the height of the notification, its is limited so it doesn't fill up the screen.

Android L - Icon background color

I'm trying to color the icon's background of my notifications on Android L. I think I saw an API during GoogleIO and the attached image actually shows a green background, but I can't find anything on the documentation.
Can you point me to something?
BONUS QUESTION: How about the background color for Wear Notification? Does it use the same API?

This color can be changed like this:
.setColor(context.getResources().getColor(R.color.theme_primary))

Getting default icon background with custom status bar notifications

I'm currently creating a custom status bar notification to notify the user of progress through an event. I have the custom notification working fine, but having a progress bar requires that I pass my own set of RemoteViews to the notification through the contentView field.
This is fine, except that I want to be able to base this layout off the default one. I am targeting API 10, and so it must work with both Gingerbread and ICS. Gingerbread is fine, as I can just put an icon on the left of the layout and the notification fits in with other default ones. In ICS however, the notification icons all have the striped square on the left that contains the icon (it effectively forms a UI "handle" to help indicate that the notification can be swiped to dismiss it).
Does anyone know how I can either get the default layout in code, and then edit it (this is hard with remoteViews), or somehow get access to default layout view (probably during runtime), then copy it, and substitute the notification text for my progress bar?

I have seen examples where people have created a notification and cloned the layout, but to do anything useful with that you have to know quite a lot about the layout. I would rather get the layout files from the android versions you are interested in. Here you have the JB one, you should not have any problems finding the others.

If the only reason you want a custom layout is to get a progress bar, you could look at
NotificationCompat.Builder.setProgress(). It'll be easier than playing with custom notification layouts. If you do decide to use custom layouts, they changed only slightly between API v14 and API v17, and I have no idea what they're like for Honeycomb but they're unlikely to be much different. What that means is that you should be able to use one custom notification layout in a layout-v11 folder, and one in your default layout folder, and you'll catch most cases (except for the icon background from Honeycomb upwards, I haven't gotten that part working in my own custom notifications yet) and only have to maintain two different layouts. See the answer above for the location of the default layout; note that it's called status_bar_latest_event_content.xml in earlier versions of Android.
Since setProgress() is available from Honeycomb upwards at least, and it looks like it works on earlier versions too (the docs don't say otherwise), then you should probably use that if you don't have any other custom requirements.
