在不同的文本视图中设置数据库值

Question

我有两个class.add和addmark。 在添加类中，我向数据库中提交了Id，姓名和电话号码。在addmark类中，当我从自动完成textview（通过添加类提交的数据库）中选择名称时，我想在两个不同的文本视图中设置Id和电话号码？

     DatabaseHandler db = new DatabaseHandler(this);

     for (StudentInfo cn : studentInfo){ 

      t1.setText("Id:"+(cn.getID()+1));

      String s2=e2.getText().toString(); 
      String s3=e3.getText().toString(); 

      if(s2.trim().equals("")||s3.trim().equals("")){ 

       Toast.makeText(getApplicationContext(), "Please Submit Student Information",Toast.LENGTH_SHORT).show(); 

       }

Answer 1

我觉得这个代码将做到这一点

a1.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
        long arg3) { 
       String id = studentInfo.get(arg2).getId(); 
       String phone = studentInfo.get(arg2).getPhone(); 
       t1.setText(id); 
       t2.setText(phone); 
      } 
     });
