Align radio buttons inside radio group

Question

I'm developing an Android 3.1 Tablet application and asking this here because I haven't found any working answer (or example) in my code.

I have the following piece of code:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1" >

    <LinearLayout
        android:id="@+id/materialsLayout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >
                                                <!-- 0 . Título del fragment -->
        <TextView

            android:layout_height="200dip" />
</LinearLayout>
</ScrollView>

I'm trying to center radio buttons inside radiogroup but I don't know how to do it.

I have tried this code:

 <RadioGroup
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
   <RadioButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_weight="1"
       android:layout_gravity="center|left"/>
   <RadioButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_gravity="center|right" />
    </RadioGroup>

But it doesn't work.

How can I do it?

It might help to try this: Align your radio group to center

<RadioGroup
                android:id="@+id/rGroupResSzOnline"
                android:layout_width="0dip"
                android:layout_height="match_parent"
                android:layout_weight=".07"
                android:gravity="center"
                android:orientation="horizontal" >

                <RadioButton
                    android:id="@+id/rResSzOnlineYes"
                    android:layout_width="wrap_content"
                    android:layout_height="match_parent"
                    android:text="Yes" />

                <RadioButton
                    android:id="@+id/rResSzOnlineNo"
                    android:layout_width="wrap_content"
                    android:layout_height="match_parent"
                    android:text="No" />
            </RadioGroup>

What if i want one radio button on left side, other on right side and another at top...?? — Devashish Prasad, Feb 26 '18 at 16:55

Since RadioGroup overrides linearlayout, you can align the radiobutton similar to child views of linear layout.

if you want to align all child radiobuttons to centre: <RadioGroup.... android:gravity="centre" ...>
if you want one radio button at start another at end:
<RadioButton1... android:layout_weight="1".../>
<RadioButton2... android:layout_weight="1".../>
it will assign equal space to both RadioButtons if you want to force align RadioButton2 to extreme end, just do not assign layout_weight to it.

Have you tried to nest a LinearLayout or RelativeLayout inside the RadioGroup and put the RadioButton within it? I haven't tried myself so I don't know if it works.

If you do like this, RadioGroup will not work, because RadioButtons must be direct children of RadioGroup; – Serhii Nadolynskyi Jan 17 '14 at 13:03
