There are several **easy** ways to do that. One involves using a ShapeDrawable (xml). Another one involves using a 9 patch (png). Then there are the **hard** ways to do that... programmatically.

I think you should use GradientDrawable.

here is an example :

GradientDrawable gdDefault = new GradientDrawable();
ColorDrawable cd = new ColorDrawable(0xFFFF6666);
gdDefault.setColor(bgColor);
gdDefault.setCornerRadius(cornerRadius);
gdDefault.setStroke(strokeWidth, strokeColor);
yourView.setBackgroundDrawable(cd);

How can i get button previous attributes and appear them again in this solution? Like background,color and etc.. – Dec 06 '14 at 12:34
I think you can just `setCornerRadius` and don't use other methods in my example and then you don't need previous attributes ;) – Mohammad Rahchamani Dec 06 '14 at 12:36
I used just setCornerRadius ,but my previous background attribute in xml layout missed with this code – Dec 06 '14 at 12:37

if your background was `transparent` it should be ok but if you are setting custom background to your view, use `gdDefault.setBackgroundDrawable(view.getBackgroundDrawable());` – Mohammad Rahchamani Dec 06 '14 at 12:39
I've just edited my answer for your use. see it again :) – Mohammad Rahchamani Dec 06 '14 at 12:41

You can do it using GradientDrawable.

 GradientDrawable shape =  new GradientDrawable();
 shape.setCornerRadius(8);

 ImageButton ivButton = (ImageButton) findViewById( R.id.ivbtn );
 ivButton.setBackgroundDrawable(shape);

Enjoy!!!

Use setBackgroundDrawable instead of setBackground. – Ganesh Katikar Dec 06 '14 at 13:39
