How to set a stroke color for drawing a rectangle on canvas?

Question

I want to draw a round rectangle that is blue and its fill is red, but I cannot find a method in the Paint class to set the color of the stroke. How can i do this?

    mCanvas.drawColor(mBackgroundColor, PorterDuff.Mode.CLEAR);
    mCanvas.setDrawFilter(mPaintFlagsDrawFilter);

    mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
    mPaint.setColor(Color.RED);
    mPaint.setStrokeWidth(2);
    mPaint.setStrokeCap(Paint.Cap.ROUND);
    mRectF.set(0, 0, mWidth, mHeight);
    mCanvas.drawRoundRect(mRectF, 10, 10, mPaint);

Paint allows only one color at a time.

mCanvas.drawColor(mBackgroundColor, PorterDuff.Mode.CLEAR);
mCanvas.setDrawFilter(mPaintFlagsDrawFilter);

mFillPaint.setStyle(Paint.Style.FILL);
mFillPaint.setColor(Color.RED);
mStrokePaint.setStyle(Paint.Style.STROKE);
mStrokePaint.setColor(Color.BLUE);
mStrokePaint.setStrokeWidth(2);
mStrokePaint.setStrokeCap(Paint.Cap.ROUND);
mRectF.set(0, 0, mWidth, mHeight);
mCanvas.drawRoundRect(mRectF, 10, 10, mFillPaint);
mCanvas.drawRoundRect(mRectF, 10, 10, mStrokePaint);

If you find that your rounded rectangle does not look right, you can crop it within the boundaries of the view. Adjust RectF to allow half StrokeWidth:

mRectF.set(1, 1, mWidth - 1, mHeight - 1);
