Android：數組適配器和ListView，拋出一些奇怪的引用錯誤？

Question

我正在嘗試創建一個自定義消息應用程序。只是基本的東西，但我得到了一些我從未聽說過的錯誤。試了兩天來修復它，所以我想我會打擾你們。這是代碼：

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    ListView messages = (ListView) findViewById(R.id.messages); 
    msgList = getSMS(); 
    for(int i = 0; i<msgList.size(); i++) { 
     System.out.println(msgList.get(i)); 
    } 
    adapter = new ArrayAdapter<String>(MainActivity.this, 0, R.layout.list_item, msgList); 
    **messages.setAdapter(adapter);** 
    messages.setOnItemClickListener(new OnItemClickListener() 
    { 
     public void onItemClick(AdapterView<?> parent, View view, int pos,long id) 
     { 
       SmsManager m = SmsManager.getDefault(); 
       String destinationNumber=(String) ((TextView) view).getText();    
       m.sendTextMessage(destinationNumber, null, destinationNumber, null, null); 
     }   
    }); 
} 

public List<String> getSMS() {  
    List<String> messages = new ArrayList<String>(); 
    Uri uri = Uri.parse("content://sms/inbox"); 
    Cursor c = null; 
    try{ 
     c = getApplicationContext().getContentResolver().query(uri, null, null ,null,null); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 
    try{ 
     for (boolean hasData = c.moveToFirst(); hasData; hasData = c.moveToNext()) { 
      final String address = c.getString(c.getColumnIndex("address")); 
      final String body = c.getString(c.getColumnIndexOrThrow("body")); 
      messages.add("Number: " + address + ". Message: " + body); 
     } 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 
c.close(); 
return messages; 
} 

這裏是錯誤：

我知道當我設置適配器的錯誤發生，但我已經檢查正在獲取的信息很好，我不能似乎找到錯誤發生的地方。 關於錯誤的任何想法非常感謝！

編輯：是的，對不起，這裏是list_item.xml。如果有幫助，我有一個類似的程序在2.1手機上工作，但在2.2上拋出此錯誤。然而，在2.1上沒有嘗試過這個應用程序。

<?xml version="1.0" encoding="UTF-8"?> 
<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:padding="15dp" 
    android:textSize="22sp" > 
</TextView>

試着改變你的ArrayAdapter的構造線：

adapter = new ArrayAdapter<String>(this, R.layout.list_item, msgList); 

在原來的線，你告訴一個ArrayAdapter到爲0的ID膨脹的佈局（不存在），然後找到一個ID爲R.id.list_item的TextView。您的TextView沒有設置ID，因此您需要使用只接受TextView資源ID的構造函數。另一個構造函數可用於更復雜的ListView項目，其中可能有多個視圖。

或者，你可以給你的TextView的ID，如 「@ + ID /文本」，然後使用：

adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.text, msgList);
