06-07 …我的代码有问题.我想listview用以下代码删除自定义中的所有项目:
public void delete_all()
{
int count = getCount();
if(count>0)
{
for (int i = 0; i < count; i++)
{
data.remove(data.get(i));
}
notifyDataSetChanged();
}
}
public Object getItem(int position)
{
return position;
}
但结果,只有项目可见删除的地方,例如:有count = 5项,结果只有3 项可见被删除,2项未被删除,
data.remove(data.get(i));
我试着改变data.remove(i);
同样的结果;
