Border over a bitmap with rounded corners in Android

I used the below to make a bitmap with rounded corners. Now I want to draw a line around the bitmap.

private BitmapDrawable roundCornered(BitmapDrawable scaledBitmap, int i) {

        Bitmap bitmap = scaledBitmap.getBitmap();

        result = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(),
                Bitmap.Config.ARGB_8888);
        canvas = new Canvas(result);

        color = 0xff424242;
        paint = new Paint();
        rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
        rectF = new RectF(rect);
        roundPx = i;
        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.BLUE);
        canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);
        BitmapDrawable finalresult = new BitmapDrawable(result);
        return finalresult;
    }

I got the image below, but my actual need is that I must draw a border around the image.

I put the following together for myself.

public static Bitmap getRoundedCornerBitmap(Bitmap bitmap, int color, int cornerDips, int borderDips, Context context) {
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(),
            Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(output);

    final int borderSizePx = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, (float) borderDips,
            context.getResources().getDisplayMetrics());
    final int cornerSizePx = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, (float) cornerDips,
            context.getResources().getDisplayMetrics());
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
    final RectF rectF = new RectF(rect);

    // prepare canvas for transfer
    paint.setAntiAlias(true);
    paint.setColor(0xFFFFFFFF);
    paint.setStyle(Paint.Style.FILL);
    canvas.drawARGB(0, 0, 0, 0);
    canvas.drawRoundRect(rectF, cornerSizePx, cornerSizePx, paint);

    // draw bitmap
    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);

    // draw border
    paint.setColor(color);
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth((float) borderSizePx);
    canvas.drawRoundRect(rectF, cornerSizePx, cornerSizePx, paint);

    return output;
}

How about to prepare 9-patch image like below and set it as a background by using android:background

I use BitmapShader and drawRoundRect do it and it work for me, look at the screenshot

RectF roundRect; // the Rect you have to draw into
Paint mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);

// draw the border at bottom
mPaint.setStyle(Paint.Style.FILL);
mPaint.setColor(mBorderColor);
canvas.drawRoundRect(roundRect, mRadius, mRadius, mPaint);

// ------------------ draw scheme bitmap
roundRect.set(itemRect.left + mBorderSize, itemRect.top + mBorderSize, itemRect.right - mBorderSize, itemRect.bottom - mBorderSize);
Shader shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mPaint.setShader(shader);
canvas.drawRoundRect(roundRect, mRadius, mRadius, mPaint);
mPaint.setShader(null);
