Change color of one LinearLayout to two colors by using canvas

Question

I'm trying to change background color of one LinearLayout to two colors for some reasons like the following pic:

I'm writing this code but the problem this LinearLayout take third different color for the two parts like this pic:

What is the problem in the logic of my code I don't know or I can not do something like that in Android?

Code:

c = (LinearLayout) findViewById(R.id.cell);
c.setBackgroundColor(getColor(container.get(0)));
c.setBackgroundColor(getColor(container.get(1)));
int width = c.getWidth(), height = c.getHeight();
if (width == 0 || height == 0) {
    width = 100;
    height = 100;
}
Bitmap bitmap;
try {

    bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
} catch (Exception e) {
    e.printStackTrace();
    return;
}

Canvas canvas = new Canvas(bitmap);

Path path = new Path();
path.moveTo(0, height);
path.lineTo(0, 0);
path.lineTo(width, 0);
path.lineTo(0, height);
path.close();

Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL_AND_STROKE);
paint.setColor(getColor(container.get(0)));
canvas.drawPath(path, paint);

path = new Path();
path.moveTo(width, 0);
path.lineTo(width, height);
path.lineTo(0, height);
path.lineTo(width, 0);
path.close();

paint = new Paint();
paint.setStyle(Paint.Style.FILL_AND_STROKE);
paint.setColor(getColor(container.get(1)));
canvas.drawPath(path, paint);

I solved my problem, the problem was in the way of parsing color in setColor method I replaced this one:

paint.setColor(getColor(container.get(1)));

by:

paint.setColor(ResourcesCompat.getColor(getResources(),getColor(container.get(1)), null));

and everything is ok now.
