title: Pagination listview in large data loading in Android
body: <p>I have a database and am loading data from that to a listview. I write to get 20 items from the database after the user scrolls the listview to the end to get another 20 items from the database and add to the listview, but there is a problem on loadinging one or two items in loading to the listview; I can't see any data in the listview. My code is:</p>
  
  <pre><code>private ListviewAdapter adapter;
  list.setOnScrollListener(new OnScrollListener() {
      @Override
      public void onScrollStateChanged(AbsListView arg0, int arg1) {
  
      }
  
      @Override
      public void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, final int totalItemCount) {
          if (totalItemCount &gt; 0)
          {
              int lastInScreen = firstVisibleItem + visibleItemCount;
              if(lastInScreen == totalItemCount)
              {
                  Parcelable state = list.onSaveInstanceState();
  
                  //Fill my_array
                  adapter = new ListviewAdapter(MainActivity.this, my_array);
                  list.setAdapter(adapter);
                  list.onRestoreInstanceState(state);
              }
          }
      }
  });
  </code></pre>
  
  <p>When the data loaded is larger than the screen, it works fine, but when the loaded data is smaller than the screen, I don't see anything in the listview.</p>
  
  <p>How can I fix this problem?</p>
