ListView中的EditText具有重复的光标位置android

Question

我有一个listview，其中有一个edittext。当我点击edittext的第一个位置并在其上写一些内容时，相同的文本将写在listview的不同位置的edittext的相同字段id的另一个edittext中。

过去12个小时我一直被困在这里。我试图搜索每个地方，但我没有找到任何答案。

这是我的适配器类代码

公共类AttendanceSheetAdapter扩展了ArrayAdapter {

Activity activity;
LayoutInflater inflater;
String trip, vehicleNo, msg;
ArrayList<Datalist> datalists;
int a;
boolean b;

public AttendanceSheetAdapter(Activity activity, int resource, ArrayList<Datalist> datalists) {
    super(activity, resource, datalists);
    this.activity = activity;
    this.datalists = datalists;

}

@Override
public int getCount() {
    return datalists.size();
}

@Override

我已编辑您的代码尝试使用以下代码并检查它是否有效：

    Activity activity;
        LayoutInflater inflater;
        String trip, vehicleNo, msg;
        ArrayList<Datalist> datalists;
        int a;
        boolean b;

        public AttendanceSheetAdapter(Activity activity, int resource, ArrayList<Datalist> datalists) {
            super(activity, resource, datalists);
            this.activity = activity;
            this.datalists = datalists;

        }

        @Override
        public int getCount() {
            return datalists.size();
        }

        @Override
