If you want to center an item in the center of the screen use a Relativelayout because linear layout is use for displaying items in a row.

Like This

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

<Button
    android:id="@+id/stage1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:background="#65f077cc"
    android:text="S T A G E" />


</RelativeLayout>

If you want to center an item in the center of a row use the below sample.

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

<Button
    android:id="@+id/stage1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:background="#65f077cc"
    android:text="S T A G E" />

</LinearLayout>

Although if you are strict with linear layout ONLY than you can try this.

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

<Button
    android:id="@+id/stage1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#65f077cc"
    android:text="S T A G E" />

</LinearLayout>

First remove things that might affect it. Orientations is best to be define at as high level as possible, like in your parent LinearLayout. From Button, remove (for now, add later if you still think you want them) android:orientation="horizontal", and android:layout_gravity="right|center_vertical".

Also fix the height of the button to be android:layout_height="wrap_content".

To LinearLayout, add

android:gravity="center"

Here is a good read on the differences of gravity and layout_gravity: http://sandipchitale.blogspot.fi/2010/05/linearlayout-gravity-and-layoutgravity.html

Additionally, fill_parent is deprecated, so you should switch to match_parent instead, where appropriate.

Edit: the final layout

    <LinearLayout
        android:id="@+id/table"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:orientation="horizontal" >
        <Button
            android:layout_width="98"
            android:layout_height="58"
            android:text="S T A G E"
            android:id="@+id/stage1"
            android:background="#65f077cc" />
