我有一个listview，列表视图的每个项目都有两个edittext ..我正在尝试在edittext上实现addTextChangedListener，但它不起作用，我认为它与一些焦点问题有关，listview需要当我点击一个edittext时焦点..任何人都有同样的问题??

Answer 1

尝试添加焦点检查，如下所示：

if (receiverName.hasFocus()) {
    currentItem.setName(String.valueOf(s));
    ((BookingDetailActivity)).updateReceiverInformation(position);
    notifyDataSetChanged();
}

addTextChangedListener（）不在listview android中工作
