ListView数据动态加载

  list.setOnScrollListener(new OnScrollListener() {

               //添加滚动条滚到最底部，加载余下的元素

                  public void onScrollStateChanged(AbsListView view, int scrollState) {
//             if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {//此方法可以用，但滚动条滚动到顶端，也触发
//              Toast.makeText(TestListScroll.this, "OK", Toast.LENGTH_SHORT).show();
//              bindViewData();bindViewData
//             }
          

          //此方法正好满足需求：滚动到低端，加载数据
          if(view.getLastVisiblePosition() == (view.getCount() -1)){
           bindViewData();//加载数据的方法
          }
         }

 

 

//下面的方法，可以实现滚动加载，每滚动一条，则在底端加载一条。

public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
          //滚动加载
////          Toast.makeText(TestListScroll.this, "OK" + firstVisibleItem + "|" + visibleItemCount + "|" + totalItemCount, Toast.LENGTH_SHORT).show();
//          int lastItem = firstVisibleItem + visibleItemCount;
////          Toast.makeText(TestListScroll.this, "OK" + listItem.size() + firstVisibleItem + visibleItemCount + lastItem , Toast.LENGTH_SHORT).show();
//            if (listItem.size() == lastItem && listItemAdapter.getCount() > 0) {
//             start = end;
//             end = end + 1;
//            
//             bindViewData();
//            }
         }
         });
