I have many RadioButtons in my app. The RadioButtons are too big for me. Is there any way to make them smaller?

Can't be done, the radio button is a built-in control component and as such its size is fixed.

How to change Radio Button size in Android, just select the radio group and then drag how long u want to make small. This is done by modifying the paddingLeft attribute on the RadioButton.The default padding is enough to make the button clear the text, as shown in your first image. I'd start with android:paddingLeft="0dp" which will put the button on top of the text, and experiment from there.

One quick hacky solution is to scale the button down:

<RadioButton
  android:scaleX="0.5"
  android:scaleY="0.5" />

This works great for going smaller.

For going larger, this tends to cause some clipping from the container View, so you'll likely have to hardcode the height/width of the RadioGroup to fit the scaled buttons. The button drawable can also get noticeably pixelated the larger you go, so it's not really great if you want something 3x larger...

        android:checked="true"
        style="@style/ToggleButtonStyle"
        android:button="@null"
        android:textOn="@string/btnTitle"
        android:textOff="@string/btnTitle"/>

and style:

<style name="ToggleButtonStyle">
    <item name="android:background">@drawable/background_radiobutton</item>
    <item name="android:textColor">@color/selector_text_radiobutton</item>

  • I guess you could write your own control, but keep in mind that making the controls too small could make it harder for some users to hit the control accurately when in touch mode. This would reduce usability of your app.
