字段槽0，-1的錯誤請求。 numRows行= 164，爲numColumns = 63

Question

你好我試圖通過ContentProvider的擺脫聯繫人表的數據，但它崩潰每次當我開始我的應用程序，

這裏是我的源代碼：

public class WebpreneurActivity extends ListActivity { 



     private DBHandler dbHelper; 

      private Cursor phones; 
      ImageButton imageButton; 
      public static long rowId; 
      @Override 
      protected void onCreate(Bundle savedInstanceState) { 
       Log.d("database1" ,"0"); 
       Log.d("Your Location4", "ok4:"); 
       super.onCreate(savedInstanceState); 
       Log.d("database1" ,"1"); 
       setContentView(R.layout.activity_webpreneur); 
       Log.d("database1" ,"2"); 
       //dbHelper = new DBHandler(this); 
       Log.d("database1" ,"3"); 
      // dbHelper.open(); 
        phones = getContentResolver().query(
          ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
          ContactsContract.Contacts._ID, null, 
          ContactsContract.Contacts.DISPLAY_NAME + " ASC"); 
        if (phones.getCount() > 0) { 
         while (phones.moveToFirst()) { 

          if (Integer.parseInt(phones.getString(phones 
              .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 


            String name = phones 
              .getString(phones 
                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 

            String phoneNumber = phones 
              .getString(phones 
                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
            String contactId = phones 
              .getString(phones 
                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID)); 
            System.out.println("contactId="+ contactId+ ", name=" + name + ", phoneNumber=" + phoneNumber); 

          } 

         } 
         phones.close(); 

        }}} 

而且我logcat的是：

Answer 1

只要不傳遞到ContactsContract.Contacts._ID要求query()：

phones = getContentResolver().query(
          ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
          null, null, 
          ContactsContract.Contacts.DISPLAY_NAME + " ASC"); 

更新： 其實有在你的代碼

了其他幾個問題中有ContactsContract.CommonDataKinds.Phone表中沒有ContactsContract.Contacts.HAS_PHONE_NUMBER列。你應該只需要ContactsContract.CommonDataKinds.Phone.NUMBER並檢查它是否不是空的。

而且你應該使用的while (phones.moveToNext())代替while (phones.moveToFirst())

請試試這個代碼：

phones = getContentResolver().query(
      ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
      null, null, 
      ContactsContract.Contacts.DISPLAY_NAME + " ASC"); 
    if (phones.getCount() > 0) { 
     while (phones.moveToNext()) { 

      String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      if (!TextUtils.isEmpty(phoneNumber)) { 


        String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
        String contactId = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID)); 
        System.out.println("contactId="+ contactId+ ", name=" + name + ", phoneNumber=" + phoneNumber); 

      } 

     }
