How to use apply a custom drawable to RadioButton?

Question

It looks like we can use the following in a RadioButton:

android:button="@drawable/myCustomStateBackground" 

but that drawable only occupies the spot where the radio drawable would normally go. Ideally I want my entire button background to be stateful. So when pushed, I want the entire button to look like its stuck in the pressed state. To do that, I was hoping I could do something like:

android:button="null" android:background="@drawable/myCustomStateBackground" 

but then the background drawable doesn't know about push state, like the button attribute does. Is there a way around it?

Answer 1

Give your radiobutton a custom style:

<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">     <item name="android:button">@drawable/custom_btn_radio</item> </style> 

custom_btn_radio.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_checked="true" android:state_window_focused="false"           android:drawable="@drawable/btn_radio_on" />     <item android:state_checked="false" android:state_window_focused="false"           android:drawable="@drawable/btn_radio_off" />      <item android:state_checked="true" android:state_pressed="true"           android:drawable="@drawable/btn_radio_on_pressed" />     <item android:state_checked="false" android:state_pressed="true"           android:drawable="@drawable/btn_radio_off_pressed" />      <item android:state_checked="true" android:state_focused="true"           android:drawable="@drawable/btn_radio_on_selected" />     <item android:state_checked="false" android:state_focused="true"           android:drawable="@drawable/btn_radio_off_selected" />      <item android:state_checked="false" android:drawable="@drawable/btn_radio_off" />     <item android:state_checked="true" android:drawable="@drawable/btn_radio_on" /> </selector> 

Replace the drawables with your own.

You should set android:button="@null" instead of "null".
