Can any one of you point the problem please?

Thanks.

A: 

Views don't scroll by default, except for a few exceptions like TextView. You have to use ScrollView - place your stuff in a LinearLayout and then place that inside the ScrollView.

It looks you only posted part of your layout. I will try to help anyway:

<ScrollView ....>

    <LinearLayout android:orientation="vertical" ...>

     YOUR SCROLLABLE CONTENT HERE

    <LinearLayout>

</ScrollView>
