you can try this :

 <RelativeLayout android:layout_width="fill_parent" 
    android:layout_height="fill_parent" >
  <Button android:id="@+id/btnSubmit" android:layout_width="wrap_content"
          android:text="Submit"
          android:layout_height="wrap_content" android:layout_alignParentTop="true"
          android:layout_alignParentRight = "true" android:padding = "4dp" />

  <EditText android:id="@+id/txtEdit" android:layout_width="fill_parent" 
          android:layout_toLeftOf="@id/btnSubmit"
          android:layout_height="wrap_content" android:layout_alignTop="@id/btnSubmit"
          android:layout_alignBottom = "@id/btnSubmit" android:padding = "4dp" />

 </RelativeLayout>

i m done with that adding a weight= 1 did my work.

<LinearLayout android:id="@+id/rl1" android:orientation="horizontal" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_below="@+id/message" >

<EditText android:id="@+id/search_bar" android:singleLine="true" android:hint="Search"
    android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="wrap_content"></EditText>
<Button android:id="@+id/search_submit" android:layout_height="wrap_content" android:layout_width="wrap_content"
    android:layout_alignParentRight="true" android:text="Search"></Button>
</LinearLayout>
