Question

我正在浏览git hub中提供的Infinite Scroll Listview代码。 https://github.com/weixiao1984/Android-Infinite-Scroll-Listview。我发现，超级关键词在Android Studio和Eclipse中显示为错误，完全没问题。请检查下面的代码，其中使用了超级关键字。 InfiniteScrollListView.super 行显示错误。由于此错误，我无法在Android Studio中构建项目。请帮我解决Android Studio的问题。提前谢谢。

 @Override
public void setAdapter(ListAdapter adapter) {
    // Force the list view to accept its own type of adapter
    if (!(adapter instanceof InfiniteScrollListAdapter)) {
        throw new IllegalArgumentException(InfiniteScrollListAdapter.class.getSimpleName() + " expected");
    }
    // Pass information to adaptor
    InfiniteScrollListAdapter infiniteListAdapter = (InfiniteScrollListAdapter) adapter;
    infiniteListAdapter.setLoadingMode(loadingMode);
    infiniteListAdapter.setStopPosition(stopPosition);
    infiniteListAdapter.setInfiniteListPageListener(this);
    this.setOnScrollListener(infiniteListAdapter);
    // Workaround to keep spaces for header and footer
    View dummy = new View(getContext());
    addLoadingView(InfiniteScrollListView.super,dummy);
    super.setAdapter(adapter);
    removeLoadingView(InfiniteScrollListView.super, dummy);
}

添加加载方法

 //Add loading view method
private void addLoadingView(ListView listView, View loadingView) {
    if (listView == null || loadingView == null) {
        return;
    }
    // Avoid overlapping the header or footer
    if (!loadingViewVisible) {
        if (loadingMode == LoadingMode.SCROLL_TO_TOP) {
            // Add loading view to list view header when scroll up to load
            listView.addHeaderView(loadingView);
        } else {
            // Add loading view to list view footer when scroll down to load
            listView.addFooterView(loadingView);
        }
        loadingViewVisible = true;
    }
}

Answer 1

根据评论中的讨论。方法addLoadingView(ListView listView, View loadingView);需要ListView。如果您有InfiniteScrollListView的实例。您可以将其传递给此方法。因为InfiniteScrollListView 是A ListView。
