How to set a hex color to an ImageView inside a notification?

Question

I'm trying to set a color as an image to an ImageView that exists inside a custom notification. I can give it predefined colors by writing this line:

remoteViews.setImageViewResource(R.id.imageView, R.color.Green);

But i want to be able to give it hex color values, and set that as the color. I tried setting the color as the background of the ImageView, but i couldn't get access to it, and the only options i have to access the ImageView are these:

remoteViews
    .setImageViewResource()
    .setImageViewBitmap()
    .setImageViewIcon()
    .setImageViewUri()

Is there a way to pass in a color by parsing the hex value to any of these? I think if I was able to create a bitmap and set the bitmap to the image view, it could be done, so i wrote the code bellow to create the bitmap:

    int[] colors = {Color.parseColor("#64DD17"), Color.parseColor("#D32F2F")};
    Bitmap bitmap = Bitmap.createBitmap(colors, 10, 10, Bitmap.Config.RGB_565);

, but i get a java.lang.ArrayIndexOutOfBoundsException . I tried with one element in the colors array too, but same error. What is my error here?

Answer 1

The int[] is your image; so you create an image 2px wide, since that's the length of your array. However, you call createBitmap and specify that the image is in fact 10px x 10px ; this is why the ArrayIndexOutOfBoundsException is thrown, as Android starts looking for pixels that aren't there.

Using Bitmap bitmap = Bitmap.createBitmap(colors, 2, 1, Bitmap.Config.RGB_565); would solve this problem, albeit generate a very tiny image!

Answer 2

Simple solution: generate png images(or use svg) to put inside the image view, instead of the color you want.

but, if u want to use that approach, you can create a colored bitmap using something like that:

Bitmap image = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
  image.eraseColor(android.graphics.Color.GREEN);
