[android help] Android: included layout not filling parent width

I have a main layout in which I include two inner layouts. I am specifying the width of the included layouts to match_parent but they don't occupy the entire width of the parent.

See example below: main_layout.xml

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingTop="5dp"
    android:baselineAligned="false"
    android:orientation="vertical" >

            android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.95" >

                    android:id="@+id/tableRow1"
            android:layout_weight="0.8"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp" >

                            android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        

                    android:id="@+id/tableRow2"
            android:layout_weight="0.2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp" >

                            android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        
    

             android:layout_width="match_parent"
         android:layout_height="50dp"
         android:layout_weight="0.05"
         android:gravity="center"
         android:orientation="vertical">  

                   android:layout_width="80dp"
           android:layout_height="40dp"
           android:textSize="14sp"
           android:textStyle="bold"
           android:text="Bottom" />
    

child_layout

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

            android:id="@+id/leftLayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:orientation="vertical" >

                    android:layout_width="80dp"
            android:layout_height="40dp"
            android:textSize="14sp"
            android:textStyle="bold"
            android:text="Left" />
    

            android:id="@+id/rightLayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:orientation="vertical" >

                  android:layout_width="80dp"
           android:layout_height="40dp"
           android:textSize="14sp"
           android:textStyle="bold"
           android:text="Right" />
    

Notice that the left and right buttons are overlapped in the image.. How do I expand the included layout to fill the entire width of the parent so that the left and right buttons appear on left and right. Thank You.
