title: Android: Using EndlessScrollListener in listview just keeps on loading data when scrolled up
body: <p>This is my EndLessScrollListener.java. Does anyone have faced this issue wherein you scroll up and it keeps on scrolling right to the top of the list.I am building a app similar to hangouts for chat messages wherein the latest message is right at the bottom. So to view the older chat messages the user scrolls up and it keeps on scrolling right to the top. Please help. FYI I am using these two attributes in my listView:
          android:stackFromBottom="true"
          android:transcriptMode="normal"</p>
