为什么在listview上只显示一行，不论list有几个数据，都只显示第一行的

Question

而且在app inspection里查看数据库，显示nodebuggable process detected

dataBase.getAll();
            Cursor cursor=dataBase.getReadableDatabase().query(DataBase.TABLE1,null,null,null,null,null,null);
            useradapter useradapter=new useradapter(this,cursor);
            userview.setAdapter(useradapter);

public ArrayList<User> getAll() {
        ArrayList<User>list=new ArrayList<User>();
        SQLiteDatabase db = getReadableDatabase();
        Cursor cursor = db.query(TABLE1, null, null, null, null, null, null);
      while (cursor.moveToNext()){
          do {
              @SuppressLint("Range") User user=new User(
                      cursor.getString(cursor.getColumnIndex(COLUMN_NAME)),
              cursor.getInt(cursor.getColumnIndex(COLUMN_AGE)),
              cursor.getInt(cursor.getColumnIndex(COLUMN_WEIGHT))
              );list.add(user);
              //Toast.makeText(mcontext, user.getName()+user.getAge()+user.getWeight(), Toast.LENGTH_SHORT).show();
//              Log.i("",user.getName()+user.getAge()+user.getWeight());
          }while (cursor.moveToNext());
      }cursor.close();
      return list;
    }

 @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        Viewuser viewuser;
        if (convertView==null){
            viewuser=new Viewuser();
            convertView=LayoutInflater.from(context).inflate(R.layout.listview2,null);
            viewuser.name=convertView.findViewById(R.id.name);
            viewuser.age=convertView.findViewById(R.id.age);
            viewuser.weight=convertView.findViewById(R.id.weight);
            convertView.setTag(viewuser);
        }else viewuser=(Viewuser) convertView.getTag();
        if (cursor.getCount()!=0){
            if (cursor.moveToPosition(position)){
                viewuser.name.setText(DataBase.slh(context).getName(cursor));
                viewuser.age.setText(DataBase.slh(context).getAge(cursor));
                viewuser.weight.setText(DataBase.slh(context).getWeight(cursor));
            }
        }
        return convertView;
    }

检查ListView适配器是否正确绑定所有数据。
