Answer 1

在ListView監聽器實現OnScrollListener您ListView

@Override 
public void onScroll(AbsListView absListView, int firstVisible, int visibleCount, int totalCount) { 
    //firstvisible is your first visible item in the list 
} 

Answer 2

覆蓋的OnScrollListener方法

list.setOnScrollListener(new OnScrollListener() { 

     @Override 
     public void onScrollStateChanged(AbsListView view, int scrollState) { 




     } 

     @Override 
     public void onScroll(AbsListView view, int firstVisibleItem, 
       int visibleItemCount, int totalItemCount) { 

      if (list.getLastVisiblePosition() == totalItemCount - 1 
        ) { 

       Toast.makeText(getActivity(), "Last", Toast.LENGTH_SHORT) 
         .show(); 


       try { 

       } catch (Exception e) { 
       } 

      } 

     } 
    });
