I have designed an activity in which i have two radio button but those size are more than enough i want to decrease it i am using text size that decreases only text if lay
visit this page http://android-holo-colors.com/ , select Radio and download the output resources (zip file contains a "res" folder), That contains all images for all posible radio button states, replace images with your custom but keeping the size of the download files. If you think it has too much states simply erase from selector in xml drawable theme.
