在滚动时更改的ListView EditText值也采用重复条目

请帮助解决我的问题!!

在活动中有一个列表视图和一个按钮

ListView Row包含一个TextView，它显示Serial No和3 Edittexts（其中将输入值）

该按钮向List添加另一行。

我使用了自己的类MemberEntry。

问题是在列表视图中，数据输入顺畅但滚动时输入 textview值（序列号）仍然很好但是 edittext（全部3）更改的值（列表中某些其他Edittext的值取代另一个）。 我使用this并发现了一些不错的结果。但不准确。

代码

活动

的OnCreate 

 MemberEntry m = new MemberEntry();
 memberEntries = new ArrayList<>();
 memberEntries.add(m);


 adapter = new CustomListViewAdapter3(this, R.layout.row_entry_member, memberEntries);
 LVMembers.setAdapter(adapter);

点击按钮

public void fab(View view) {
    memberEntries.add(new MemberEntry());//memberEntries and adapter are global
    adapter.notifyDataSetChanged();
}

适配器

public class CustomListViewAdapter3 extends ArrayAdapter<MemberEntry> {
Context context;
int layoutResourceId;
public String[] Current;
ArrayList<MemberEntry> data = new ArrayList<>();
public static HashMap<Integer,String> myListOfNames=new HashMap<Integer,String>();


public CustomListViewAdapter3(Context context, int layoutResourceId,
                              ArrayList<MemberEntry> data) {
    super(context, layoutResourceId, data);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    Current=new String[50];
    this.data = data;
    Log.d("CustomListViewAdapter", "Data = " + data + "\n Data Length = " + data.size() + "\n getCount=" + getCount());
    for(int i=0;i<50;i++)
