Answer 1

You can define a selector for your radio button as described in this answer:

Answer 2

Just create a selector xml file in drawable folder

checkbox_background.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
      <item android:state_checked="true" android:drawable="@color/checkbox_active" />
      <item android:state_checked="false" android:drawable="@color/checkbox_inactive" />
</selector>

And apply this background to your radio buttons

 <RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/checkbox_background" />

Answer 3

Use

android:gravity="center"

for the radio button. This will center the text.
