Answer 2

Try this, Have you tried this one?. Add windowSoftInputMode attribute in particular activity

android:windowSoftInputMode="adjustPan"

In your xml. add android:layout_alinParentTop="true" in your top relativelayout

 <RelativeLayout
android:id="@+id/topLay"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/jam_alert_topbar"
android:layout_alinParentTop="true"
 >
</RelativeLayout>
