I think, you can use a ListView insted of scroll view. and add list items from the chat text value dynamically. call notifydatasetchanged() every time when you add a new item to it.

<TextView
    android:id="@+id/username"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:gravity="center_vertical"
    android:layout_alignParentTop="true"
    android:textColor="#000000"
    android:text="aakash"
    android:background="#c0c0c0"
/>

<ListView
                android:id="@+id/listView_chats"
                android:layout_width="match_parent"
                android:layout_height="100dp"
                >
            </ListView>


<EditText
    android:id="@+id/chattxt"
    android:layout_width="230dp"
    android:layout_height="45dp"
    android:hint="type here"
    android:inputType="textMultiLine" />

<Button
    android:id="@+id/sendbtn"
    android:layout_width="75dp"
    android:layout_height="45dp"

    android:text="Send" />

</LinearLayout>

Write a custom adapter for the listView and add the code to manage the list data.
