C#, Android: Create bitmap with single color
1
I want to create a bitmap that is filled with only one color (#eeeeee).
I managed to create a bitmap and set it to its viewholder but I cannot seem to find the right way to fill it entierely with my desired color. The output is always only a white rectangle. But it needs to be greyish as in #eeeeee. This is my effort:
Bitmap greyBitmap = Bitmap.CreateBitmap(1000, 500, Bitmap.Config.Argb8888);
Bitmap mutableBitmap = greyBitmap.Copy(Bitmap.Config.Argb8888, true);//<–true makes copy mutable
Canvas canvas = new Canvas(mutableBitmap);
Paint paint = new Paint();
paint.Color = new Color(Color.ParseColor("#eeeeee"));
canvas.DrawRect(1000, 500, 1000, 500, paint);
vh.dr = new BitmapDrawable(mutableBitmap);
Chances are, I am taking too many steps... Feel free to correct me on this.

The coordinates you have inDrawRect()are off. The first two should be0, 0. Anyway, there's a much simpler way to do that. Just calleraseColor()with your color value on the mutableBitmap.

Oh, I'm good. Just a couple simple suggestions. :-) Please feel free to post your own answer. This would be a handy duplicate target in the future for users asking specifically for C# code. Btw, I just double checked, and that particularBitmap.CreateBitmap()overload returns a mutableBitmapalready, so there's no need to copy it first. You can do the whole thing in two lines. Anyhoo, thanks for the offer. I appreciate it. Glad you got it working. Cheers!
