ListView滚动加载(类似Android Market的列表)

ListView滚动加载(类似Android Market的列表)?

?listView.setOnScrollListener(new OnScrollListener() {

??? @Override
??? public void onScrollStateChanged(AbsListView view, int scrollState) {}
??? @Override
??? public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
??????? //滚动条滚到最底部，加载余下的元素
??????? if (firstVisibleItem + visibleItemCount == totalItemCount)
??????????? loadRemnantListItem();
??? }
});
private void loadRemnantListItem() {//滚到加载余下的数据
??? //动态的改变listAdapter.getCount()的返回值
??? //调用listAdapter.notifyDataSetChanged();更新数据
}

?

至上下两个端，可以用

?

@Override

public void onScrollStateChanged(AbsListView view, int scrollState) {

if (scrollState == OnScrollListener.SCROLL_STATE_IDLE ) {

loadApprovalListItem();

}

}

判断，也是setOnScrollListener的方法
