ListView 滚动翻页/滚动加载(类似Android Market的列表)

1.滚动加载

 

listView.setOnScrollListener(new OnScrollListener() {
    //添加滚动条滚到最底部，加载余下的元素
    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
        if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {
            loadRemnantListItem();
        }
    }
    @Override
    public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {}
    });


listView.setOnItemSelectedListener(new OnItemSelectedListener() {
    //按键选择List中的item，焦点落在最下面的view上加载余下的item
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        if(footerView == view) {
            loadRemnantListItem();
            listView.setSelection(position - 1);
        }
    }
    @Override
    public void onNothingSelected(AdapterView<?> parent) {}
    });

private void loadRemnantListItem() {//滚到加载余下的数据
    //动态的改变listAdapter.getCount()的返回值
    //使用Handler调用listAdapter.notifyDataSetChanged();更新数据
}

2.滚动翻页

//listView监听器代码相同
private void loadRemnantListItem() {//滚到加载余下的数据
    //重新listView.setAdapter(newsAdapter);
    //使用Handler调用listAdapter.notifyDataSetChanged();更新数据
}
