This is the code I am using and it is not working:

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

    <TextView android:text="TextView" android:id="@+id/textView1"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:gravity="right">
    </TextView>

</LinearLayout>

Answer 1

Try to add empty View inside horizontal LinearLayout before element that you want to see right, e.g.:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <View
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_weight="1" />                

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>
