Question

Is it possible to create a button like radio button without using images?
Would like to have a pressed state upon selection. Then back to normal state when I click other options.

Answer 1

simply include the respective drawables of the radio button in different states (i.e. focused, pressed, checked, or normal). Include these in a selector.xml to specify the looks of the button for the respective states, and include that xml in the android:background attribute of your button. That should do it all…! 🙂

Check this link to understand the method better: Change how a CheckBox looks
(it is given for a CheckBox, but similar stuff will work for button as a radio button as well).

Edit:

Define round_button.xml as below:

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

    <item android:state_checked="false" android:state_focused="true"
        android:drawable="@drawable/roundbutton_off_background_focus_yellow" />

    <item android:state_checked="false" 
        android:drawable="@drawable/roundbutton_off_background" />

    <item android:state_checked="true"
        android:drawable="@drawable/roundbutton_on_background" />
</selector>

Then, wherever you need to include that button, just add the following:

<Button android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/round_button"
    android:checked="true"/>

[P.S.: Don’t forget to include the drawables for a round button, you’ll have to search them yourself, or get from the default files (.android), which is given in the link]
