</RelativeLayout>

Iam facing a hard time to arrange them horizontally.Any help is appreciated.

Solution 1:

To place a radiogroup (or any other view) above other just do:

android:layout_above="@+id/view_below"

To change the orientation just set:

android:orientation="horizontal"

And to give equal width to items make use of layout_weight:

<RadioGroup
    android:id="@+id/radio_group"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_above="@+id/view_below" >

    <RadioButton
        android:id="@+id/radio1"
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:checked="true"
        android:text="First" />

    <RadioButton
        android:id="@+id/radio2"
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Second" />
</RadioGroup>

Solution 2:

You can use table layout instead of relative layout. Insert row into into table layout and place radio buttons inside table row..

For equal spacing follow following procedure

<TableRow
        android:id="@+id/tableRow2"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="50dp" >

        <RadioButton
            android:id="@+id/button2"
            android:layout_width="5dp"
            android:layout_height="60dp"
            android:layout_weight="1"
            android:text="@string/btnReject"
            android:onClick="onCallRejectButton" />

        <RadioButton
            android:id="@+id/button1"
            android:layout_width="5dp"
            android:layout_height="60dp"
            android:layout_weight="1
            android:onClick="onCallAcceptButton"
            android:text="@string/btnAccept" />

    </TableRow>
