Main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    >

    <Button 

        android:id="@+id/on_btn"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="Turn Flash ON" />

</LinearLayout>

Set textview and 2 buttons in a android layout

You use this relativeLayout, that the first Button (Your left button) has to be set after set the second button(Your right button). This only works, if the button, that should be right, still exists before setting the left button.

<?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="fill_parent"
    android:orientation="vertical"
    android:padding="10dip" >

    <RelativeLayout
        android:id="@+id/upperView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/darker_gray"
        android:orientation="vertical"
        android:padding="10dip" >

        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_centerVertical="true"
            android:text="Hello.."
            android:textColor="@android:color/white" />

        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:text="Button 1" />

        <Button
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toLeftOf="@+id/button1"
            android:text="Button 2" />
    </RelativeLayout>

    <ListView
        android:id="@+id/listView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/upperView" />

</RelativeLayout>
