try should work,

add android:gravity="center" @+id/tr_header_p1 , @+id/tr_header like,

<tablerow     android:id="@+id/tr_header_p1"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:gravity="center"     android:padding="5dp"> 

and

<tablerow     android:id="@+id/tr_header"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:gravity="center"     android:padding="5dp"> 

this might helps you

edit 1

or need mention android:layout_weight="1" textview.

 <textview         android:id="@+id/player2_name"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:gravity="center"         android:layout_weight="1"         android:text="player 2"         android:textcolor="#000000"         android:textsize="24sp" />
