Scroll at the bottom of the activity on onclick listener

In my Android app, I have a few views (Buttons, EditTexts etc.) not visible initially. These are visible only on a particular button click event. I wish to move the scrollview to the end of these views so that these are visible to the user. The relevant portion of the layout file: ``` <ScrollView...> <RelativeLayout android:id="@+id/RelDevDet" android:layout_width="fill_parent" android:layout_height="wrap_content"> . . . <ImageButton android:id="@+id/ibRateApp" android:layout_toRightOf="@id/tvRateApp" android:layout_alignTop="@id/tvRateApp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/arrow_up" android:clickable="true" android:layout_marginRight="5dp" android:paddingBottom="10dp" /> <RatingBar android:id="@+id/rtApp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/tvRateApp" android:layout_marginLeft="5dp" android:visibility="gone"/> <EditText android:layout_width="fill_parent" android:id="@+id/etRateApp" android:layout_height="wrap_content" android:lines="3" android:layout_below="@+id/rtApp" android:layout_marginRight="5dp" android:layout_alignLeft="@+id/tvDevWeb" android:visibility="gone" /> <Button android:id="@+id/btSubRat" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/etRateApp" android:layout_margin="5dp" android:text="Submit" android:visibility="gone"/> </RelativeLayout> </ScrollView> ``` The onclicklistener for the button is: ``` public void onClick(View v) { if(v.getId()== R.id.ibRateApp){ Log.d("amit","scroll end"); rtApp.setVisibility(View.VISIBLE); etRateApp.setVisibility(View.VISIBLE); //How to get the scrollview move to the end of the page here?? } } ```
