This Layout contains three GridViews. I am making Parent RelativeLayouts of GridViews visible with logic and adding inflated ImageView + TextView to GridView.

Its looking fine. but no scrolling is there.

yeah what is the point of having three different GridView. Just Create a single GridView as parent and have an separate layout for GridItem so you can style it the way you need to.

UPDATE

isn't something like this will work for you???

one layout with following code

        <GridView 
            android:id="@+id/gridTomorrow" 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content" 
            android:layout_alignParentBottom="true" 
            android:layout_alignParentLeft="true" 
            android:layout_below="@+id/FrameLayout1" 
            android:layout_weight="1" 
            android:numColumns="3" > 
        </GridView>

and another Layout for GridItem

        <FrameLayout   
            android:id="@+id/FrameLayout1"   
            android:layout_width="match_parent"   
            android:layout_height="wrap_content"   
            android:layout_alignParentLeft="true"   
            android:layout_alignParentTop="true" >   

            <ImageView   
                android:id="@+id/ImageView01"   
                android:layout_width="wrap_content"   
                android:layout_height="wrap_content"   
                android:src="@drawable/gridframe" />   

            <FrameLayout   
                android:layout_width="wrap_content"   
                android:layout_height="wrap_content"   
                android:layout_gravity="right"   
                android:layout_marginRight="10dp"   
                android:layout_marginTop="10dp"   
                android:background="@drawable/calender" >   

                <TextView   
                    android:id="@+id/txtDateTomorrow"   
                    android:layout_width="wrap_content"   
                    android:layout_height="wrap_content"   
                    android:layout_gravity="center"   
                    android:gravity="center"   
                    android:text="28" />   
            </FrameLayout>   

            <TextView   
                android:id="@+id/TextView02"   
                android:layout_width="wrap_content"   
                android:layout_height="wrap_content"   
                android:layout_marginLeft="10dp"   
                android:layout_marginTop="3dp"   
                android:text="Tomorrow"   
                android:textColor="#000" />   
        </FrameLayout> 

using an GridAdapter Inflate your GridItems into grid
