i unable uncheck radio buttons. have posted java code , xml code.thanks in advance.

do not try checked , unchecked radiobutton pragmatically ...just put radio button in 1 radiogroup in xml row layout file.

  <linearlayout             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:orientation="vertical"             android:padding="@dimen/marginten" >              <radiogroup                 android:id="@+id/radiogroup1"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content" >                  <radiobutton                     android:id="@+id/radiobutton1"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="radiobutton" />                  <radiobutton                     android:id="@+id/radiobutton2"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="radiobutton" />                  <radiobutton                     android:id="@+id/radiobutton3"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:text="radiobutton" />             </radiogroup>         </linearlayout>
