android - Center two buttons horizontally

Question

I try to arrange two buttons (with images on them which work fine) next to each other and to center them horizontally. That's what I have so far:

<LinearLayout android:orientation="horizontal" android:layout_below="@id/radioGroup"
              android:layout_width="wrap_content" android:layout_height="wrap_content"
              android:layout_gravity="center_horizontal|center">
    <Button
            android:id="@+id/allow"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/radioGroup"
            android:layout_gravity="center_horizontal"
            android:drawableLeft="@drawable/accept_btn"
            android:text="Allow"/>
    <Button
            android:id="@+id/deny"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@id/allow"
            android:layout_below="@id/radioGroup"
            android:layout_gravity="center_horizontal"
            android:drawableLeft="@drawable/block_btn"
            android:text="Deny"/>
</LinearLayout>

Unfortunately they are still aligned to the left side. Any help is appreciated! Yves

Edit:

Unfortunately none of the comments or suggestions work so far. That's why I try to provide a simplified, full layout now with a RelativeLayout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="fill_parent" android:layout_height="wrap_content"
            android:layout_centerHorizontal="true">
    <TextView android:text="@+id/TextView01" android:id="@+id/TextView01"
          android:layout_width="wrap_content" android:layout_height="wrap_content"/>
    <Button
        android:id="@+id/allow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/TextView01"
        android:text="Allow"/>
    <Button
        android:id="@+id/deny"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/allow"
        android:layout_alignTop="@id/allow"
        android:text="Deny"/>
</RelativeLayout>

I've tried all combinations of attributes in the LinearLayout and on the Button elements without luck. Any other ideas?

This is my solution:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:layout_centerHorizontal="true">

    <TextView
        android:text="@+id/SomeText"
        android:id="@+id/TextView01"
        android:layout_width="wrap_content" android:layout_height="wrap_content" />

    <LinearLayout
        android:orientation="horizontal"
        android:background="@android:drawable/bottom_bar"
        android:paddingLeft="4.0dip"
        android:paddingTop="5.0dip"
        android:paddingRight="4.0dip"
        android:paddingBottom="1.0dip"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:layout_below="@+id/TextView01">

        <Button
            android:id="@+id/allow"
            android:layout_width="0.0dip" android:layout_height="fill_parent"
            android:text="Allow"
            android:layout_weight="1.0" />

        <Button
            android:id="@+id/deny"
            android:layout_width="0.0dip" android:layout_height="fill_parent"
            android:text="Deny"
            android:layout_weight="1.0" />

    </LinearLayout>
</RelativeLayout>
