[android] Vertical line using XML drawable

add this in your styles.xml

        <style name="Divider">
            <item name="android:layout_width">1dip</item>
            <item name="android:layout_height">match_parent</item>
            <item name="android:background">@color/divider_color</item>
        </style>

        <style name="Divider_invisible">
            <item name="android:layout_width">1dip</item>
            <item name="android:layout_height">match_parent</item>
        </style>

then wrap this style in a linear layout where you want the vertical line, I used the vertical line as a column divider in my table. 

     <TableLayout
                android:id="@+id/table"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="horizontal"
                android:stretchColumns="*" >

                <TableRow
                    android:id="@+id/tableRow1"
                    android:layout_width="fill_parent"
                    android:layout_height="match_parent"
                    android:background="#92C94A" >

                    <TextView
                        android:id="@+id/textView11"
                        android:paddingBottom="10dp"
                        android:paddingLeft="5dp"
                        android:paddingRight="5dp"
                        android:paddingTop="10dp" />
    //...................................................................    

                    <LinearLayout
                        android:layout_width="1dp"
                        android:layout_height="match_parent" >

                        <View style="@style/Divider_invisible" />
                    </LinearLayout>
        //...................................................................
                    <TextView
                        android:id="@+id/textView12"

                        android:paddingLeft="5dp"
                        android:paddingRight="5dp"
                        android:paddingTop="10dp"
                        android:text="@string/main_wo_colon"
                        android:textColor="@color/white"
                        android:textSize="16sp" />
  //...............................................................  
                    <LinearLayout
                        android:layout_width="1dp"
                        android:layout_height="match_parent" >

                        <View style="@style/Divider" />

                        android:textColor="@color/white"

                </TableRow>

                <!-- display this button in 3rd column via layout_column(zero based) -->

                <TableRow
                    android:id="@+id/tableRow2"
