如何在 Android 中实现分页列表视图 [英] How to implement Paginated List View in Android

问题描述

我想在 android 中实现分页列表视图，所以当我向下滚动到最后时，每次应该将更多项目添加到我的列表中，目前我正在从 Web 服务中获取 10 个项目并将它们显示在列表视图中，现在我当用户向下滚动到列表末尾时，想要再添加 10 个项目.有什么办法吗?

I want to implement Paginated list View in android so when I scroll down to the end, each time more items should add to my list, currently I am fetching 10 items from web service and showing them in a list View, now I want add 10 more Items when user scroll down to the end of the list. Is there any way to do it?

public class EndlessScrollListener implements OnScrollListener {

    private int visibleThreshold = 5;
    private int currentPage = 0;
    private int previousTotal = 0;
    private boolean loading = true;

    public EndlessScrollListener() {
    }
    public EndlessScrollListener(int visibleThreshold) {
        this.visibleThreshold = visibleThreshold;
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem,
            int visibleItemCount, int totalItemCount) {
        if (loading) {
            if (totalItemCount > previousTotal) {
                loading = false;
                previousTotal = totalItemCount;
                currentPage++;
            }
        }
        if (!loading && (totalItemCount - visibleItemCount) <= (firstVisibleItem + visibleThreshold)) {
            // I load the next page of gigs using a background task,
            // but you can call any function here.
            new LoadGigsTask().execute(currentPage + 1);
            loading = true;
        }
    }

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