Show TextView always on top

In my app, I´ve got 20 buttons that cover the whole display. Always one of them is visible and every second another one is shown.
This should be a little game.

Now, I need to add a score

TextView
so that the user knows, how much points he has at the moment. What is the best way to realize that? Like I said, the whole display is covered with the 20 buttons.

Here´s the first Row of my TableLayout:

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"


android:background="@drawable/bg">


<TableRow
android:id="@+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >

<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/te"
/>

<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="70dp"


android:background="@drawable/te"
/>

<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="140dp"
android:background="@drawable/te"
/>

<Button
android:id="@+id/button4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="210dp"

android:background="@drawable/te"
/>


</TableRow>

Answer

Use FrameLayout to set TextView over your buttons or RelativeLayout.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">

   <LinearLayout ...>
   // YOUR LAYOUT WITH BUTTONS 
   </LinearLayout>

   <TextView
   android:text="TEXT OVER BUTTONS"
   android:layout_height="wrap_content"
   android:layout_width="wrap_content"
   android:gravity="center"/>
</FrameLayout>
