标签: android listview footer indexoutofboundsexception

我有一个listview,当使用onscroll listener达到20rh listitem时会加载更多的listitems

我想添加一个页脚,说明在加载更多列表项时加载更多

当我到达第20个列表项时,应用程序崩溃说idex超出了logct

我的活动

public class InterActivity extends Activity 
{

SwipeMenuListView listview;
//ListView listview;

答案 0 :(得分:0)

创建footer_view.xml,然后尝试onCreate

View footerView =  ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
list.addFooterView(footerView);
