Ohk, i got a little success using given code (and it works fine):
Bitmap borderedBitmap = addBorderToBitmap(originalBitmap, 5, Color.WHITE);
private Bitmap addBorderToBitmap(Bitmap srcBitmap, int borderWidth, int borderColor) {
Bitmap dstBitmap = Bitmap.createBitmap(
srcBitmap.getWidth() + borderWidth * 2, // Width
srcBitmap.getHeight() + borderWidth * 2, // Height
Bitmap.Config.ARGB_8888 // Config
);
Canvas canvas = new Canvas(dstBitmap);
Paint paint = new Paint();
paint.setColor(borderColor);
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeWidth(borderWidth);
paint.setAntiAlias(true);
Rect rect = new Rect(
borderWidth / 2,
borderWidth / 2,
canvas.getWidth() - borderWidth / 2,
canvas.getHeight() - borderWidth / 2,
);
canvas.drawRect(rect, paint);
canvas.drawBitmap(srcBitmap, borderWidth, borderWidth, null);
srcBitmap.recycle();
// Return the bordered circular bitmap
return dstBitmap;
}
But there's some confusion,i'm using paint.setAntiAlias(true);
to make border paint looks smooth, even with this option, border looks rough, is there any solution for this?
