答案 0 :(得分：0)
你可能会做这样的事情
//get your ListView with attached SimpleAdapter
ListAdapter adapter = listView.getAdapter();
for(int i = 0; i < adapter.getCount(); i++) {
String value = ((HashMap<String, String>)adapter.getItem(i)).get("Your_key");
}
但我不确定我是否正确理解了这个问题，你想要完成什么呢？我很抱歉在这里提出问题，但我还不准发表评论：/

onTextChangedMethod中，写一个if条件 - edittext值在列表视图中正在膨胀的列表中，如果是，则将该edittext值添加到另一个列表并将该列表设置为适配器。例如，这是我的代码： - （只关注ListView，ArrayList和TextWatcher。别介意其他代码）
