Answer 1

For this you can use a Selector

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/1" 
    android:state_pressed="true"/>  
<item android:drawable="@drawable/2" 
    android:state_checked="true"/>  
<item android:drawable="@drawable/3" 
    android:state_focused="true" />
<item android:drawable="@drawable/4" />  
</selector> 

and in the radiobutton tag you can add

android:button="@drawable/above"
android:layout_height="20dp"
android:layout_width="wrap_content"

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.
