移植ListView多維的ArrayList

Question

我想填充的ListView，如http://www.tutorialspoint.com/android/android_list_view.htm 它工作正常（見下面的代碼）

//字符串數組... 的String [] mobileArray = {「機器人「，」iPhone「，」WindowsMo​​bile「，」Blackberry「，」WebOS「，」Ubuntu「，」Windows7「，」Max OS X「};

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    ArrayAdapter adapter = new ArrayAdapter<String>(this, R.layout.activity_listview, mobileArray); 

    ListView listView = (ListView) findViewById(R.id.mobile_list); 
    listView.setAdapter(adapter); 
} 

現在，而不是這個mobileArray（一個維數組），我想用一個ArrayList

我已經填充的ArrayList名爲學生

但是當我填充它爲：

ArrayAdapter adapter = new ArrayAdapter<Student>(this, R.layout.activity_listview,Students); 

     ListView listView = (ListView) findViewById(R.id.listView); 
     listView.setAdapter(adapter); 

和運行，我得到一個奇怪的輸出

abc.mycom.com.collectionsample.Students@e3c94gh 
abc.mycom.com.collectionsample.Students@erdgdhdf 
abc.mycom.com.collectionsample.Students@eyfgbgfb 

其實學生有3行......但是，沒有價值觀，如e3c94gh

請幫我用最少的代碼改變這一點 - 我的意思是 -

我的目標就是與學生們進行替換mobileArray（用最少的代碼改變）

ArrayList population code is here: 

List<Student> Students = new ArrayList(); 


     Student student1 = new Student(); 

     student1.setStudentName("student 1"); 
     student1.setStudentNo("N0001"); 
     student1.setEmail("student1@student.com"); 
     student1.setYear(1991); 

     Students.add(student1); 


     Student student2 = new Student(); 

     student2.setStudentName("Student 2"); 
     student2.setStudentNo("N0002"); 
     student2.setEmail("student2@student.com"); 
     student2.setYear(1992); 

     Students.add(student2); 


     Student student3 = new Student(); 

     student3.setStudentName("Student 3"); 
     student3.setStudentNo("N0003"); 
     student3.setEmail("student3@student.com"); 
     student3.setYear(1993); 

     Students.add(student3); 

Answer 1

它應該是：

ArrayAdapter<Student> adapter = new ArrayAdapter<Student>(this, R.layout.activity_listview,Students); 

哪裏是你的Stude nts arrayList ???
