Try this...this will definitly solve your problem..

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

<Chronometer
    android:id="@+id/chrono"
    android:textColor="#4169E1"
    android:textSize="20sp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
   android:layout_alignParentTop="true"
    android:text="Chronometer"
/>

<TableLayout 
    android:id="@+id/parentLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/chrono"
    >
</RelativeLayout>

Answer 2

First Stick Chronometer to bottom android:layout_alignParentBottom="true" then take TableLayout on above of Chronometer

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/firstLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TableLayout
        android:id="@+id/parentLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/chrono" >
    </TableLayout>

    <Chronometer
        android:id="@+id/chrono"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:text="Chronometer"
        android:textColor="#4169E1"
        android:textSize="20sp" />

</RelativeLayout>

Answer 3

Your TableLayout takes over all space (match_parent) and draws over the Chronometer. RelativeLayout children are laid out in order they are declared. I don't know what you want exactly, but you can start by switching the order of the two in your layout so that the Chronometer draws over the TableLayout.

Answer 4

finally i got the way to display the chronometer. Thanks to everyone who tried to help me, the answers were really close to my solution which is:

<Chronometer
android:id="@+id/chrono"
android:textColor="#4169E1"
android:textSize="20sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="Chronometer"
/>
<TableLayout 
android:id="@+id/parentLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/chrono"
>
