Question

can we decrease the size of radio button in android ??

Answer 1

As far as i know the radio button can be done but not like the other EditText or TextView..

Try this code..

<RadioGroup android:layout_width="fill_parent"               
            android:layout_height="50dp"           
            android:orientation="horizontal"         
            android:checkedButton="@+id/first">  

 <RadioButton android:id="@+id/first"        
      android:width="50dp"        
      android:height="50dp"        
      android:button="@drawable/button_radio"/> 

   <RadioButton android:id="@+id/second"        
      android:width="50dp"     
      android:height="50dp"     
      android:button="@drawable/button_radio"/>

   <RadioButton android:id="@+id/third"
      android:width="50dp"
      android:height="50dp"
      android:button="@drawable/button_radio"/>

   <RadioButton android:id="@+id/fourth"                                          
      android:width="50dp"              
      android:height="50dp"           
      android:button="@drawable/button_radio"/>           
</RadioGroup>
