You can give android:layout_height="wrap_content" for each RadioButton. But your question title and the question are a bit different. In your title, you ask about how to decrease the size of image displayed, but in your question and code, you don't seem to use any image. Please re-frame your question. – Faeroese

yes i want to decrease size of default image not new image – Ossification

My question: Where's the image, mate? – Faeroese

No.. It;s not possible to change the size of default radio button's image.... If you want you can set your own image to radio button and adjust its size.. that will be the better solution to achieve your goal rather than wasting time to change radio button's image.... – Oliveira

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"

The correct way is to use your custom drawables for radio button's state. To decrease the image size for custom drawables check THIS out.

Exactly duplicate of @Alish Answere – Ossification

No sir, its different. When you use a custom drawable its a great pain to reduce its size on the radio button. Yes, it doesn't satisfy your need of not using a new image ,but, for any one who has faced difficulty reducing the size of the custom drawable ,just as I did , it works wonderfully well. – Fuegian

And by the way for FYI, @Alish's answer tells you to reduce the size of the radio button but what I am talking about is to reduce the size of image on radio button – Fuegian

Answer 5

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.
