如何从listview中存储和检索editText，每行有2个editText？
使用此代码，当我向一个editText写入内容时，它会将值复制到所有其他内容。
public class CheckoutAdapter extends BaseAdapter{
private Context mContext;

this.mContext = context;
this.mObjs = objs;

for (int i = 0; i < mObjs.size(); i++) {
arrayFirstName.add("");
arrayLastName.add("");
}
}

编辑：删除了setId和JSON。
答案 0 :(得分：0)
你的持有人是你班上的一员，这是错的。 从这个地方删除它。列表视图的每一行都有自己的持有者。 这个持有者通过setTag方法“贴在”视图上。
在使用holder的侦听器中，您必须从发送事件的视图中获取持有者。 为此，以下代码应该起作用：
private View.OnFocusChangeListener FirstNameFocusChangeListener(final int position) {
return new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus){
ViewHolder holder = (ViewHolder ) v.getTag();
viewID = holder.position;
}
}
};
}
