當閱讀聯繫人時應用程序崩潰

我試圖讀取用戶的聯繫人時發生崩潰，我以爲是因爲模擬器，但我想三重檢查，因爲我沒有基於android的手機。 Logcat提供了一個錯誤，它不能讀取「id」行我錯誤地命名該字符串？當閱讀聯繫人時應用程序崩潰

最後，我將如何實現一個對話框，以查看用戶是否希望應用程序讀取聯繫人？

非常感謝:) 代碼：

private void checkandImportContacts() { 
    // TODO Auto-generated method stub 
    SharedPreferences sp = getSharedPreferences(PREFS_CHECK, 0); 
    String checkfirstime = sp.getString("key3", null); 
    if(checkfirstime !=null && equals("sdhdasudafdsugdiasgdas38ey98d1diass")) { 
     finish(); 
    } else { 
     Cursor cursor = getContacts(); 
      while (cursor.moveToNext()) { 
       String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME)); 
       Toast.makeText(getApplicationContext(), displayName, Toast.LENGTH_LONG).show(); 
     } 
} 
    } 




private Cursor getContacts() { 
    Uri uri = ContactsContract.Contacts.CONTENT_URI; 
    String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME }; 
    String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ‘" + ("1") + "’"; 
    String[] selectionArgs = null; 
    String sortOrder = ContactsContract.Contacts.DISPLAY_NAME+ " COLLATE LOCALIZED ASC"; 
    return managedQuery(uri, projection, selection, selectionArgs, sortOrder); 
}

的logcat：

你需要什麼？名稱，號碼和其他 – 2012-04-23 16:56:13

更改'''爲''' – zapl 2012-04-23 16:56:57

@ Zapi我會盡力和其他答案。謝謝。 – TheBlueCat 2012-04-23 17:12:46

您使用了錯誤的字符在查詢

Caused by: android.database.sqlite.SQLiteException: no such column: ‘1’

的SQLite試圖解釋‘1’爲列名稱，因爲它不是原始值。 SQLite中的值由'包圍，列名稱由"包圍或不包含任何內容。

如果該組的事情是動態做這樣的：

int group = 1; 
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ?"; 
String[] selectionArgs = new String[] { String.valueOf(group) };

值會自動包裝在' &然後逃走。如果該值是靜態的，你可以簡單地做

String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = 1"; 
String[] selectionArgs = null;

聯繫人不顯示在烤麪包上？我試圖做一個日誌，但這也不起作用。 – TheBlueCat 2012-04-23 17:25:31

如果你沒有得到任何錯誤，那麼你的查詢可能有其他錯誤（例如，沒有與'IN_VISIBLE_GROUP = 1'的聯繫人），或者你根本沒有聯繫。 – zapl 2012-04-23 17:47:58

我不這樣做，因爲它是模擬器，我也沒有安卓手機。 – TheBlueCat 2012-04-23 17:49:57

private void getDetails(){ 
     Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; 
     ContentResolver cr = getContentResolver(); 
     Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); 
     String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, 
         ContactsContract.CommonDataKinds.Phone.NUMBER }; 
     Cursor names = getContentResolver().query(uri, projection, null, null, null); 

     int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME); 
     int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); 
     names.moveToFirst(); 
     do { 

      String name = names.getString(indexName); 
      Log.e("Name new:", name); 
      String number = names.getString(indexNumber); 
      Log.e("Number new:","::"+number); 

     } while (names.moveToNext()); 
    }

以上retrun所有的號碼和名字從你的聯繫人數據庫..
