Android應用程序的問題讀取電話號碼

我試着去閱讀一個聯繫人的電話號碼，但我不能得到它的工作...Android應用程序的問題讀取電話號碼

我的代碼是完全一樣的here

ContentResolver cr = getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null); 

    if (cur.getCount() > 0) 
    { 
     contacts = new String[cur.getCount()]; 
     numbers = new String[cur.getCount()]; 
     int index = 0; 
     while (cur.moveToNext()) 
     { 
      String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
      String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

      contacts[index] = name;    
      MyListAdapter listAdapt = new MyListAdapter(MeetUp.this, R.layout.row, contacts); 
      MeetUp.this.setListAdapter(listAdapt); 


      if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
      { 
       Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id}, null); 
       while(pCur.moveToNext()); 
       { 
        numbers[index] = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));    
       } 
      } 
      index++; 
     } 
    }

我logcat的輸出：

它未能肯定有一些，但d後的接觸ebugging我認爲pCur沒有數字列。任何想法爲什麼會發生這種情況？在此先感謝 - 麥克

我發現了什麼問題！ while循環，特別是moveToNext（）調用使它崩潰。如果你擺脫循環，很好！

pCur.moveToFirst(); 
numbers[index] = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

我想你可能需要一個cursor.moveToFirst()調用，然後再開始枚舉。

K Nope！這沒有奏效，但無論如何感謝！ – mixkat 2011-03-25 17:14:45

代碼中的哪一行導致異常被拋出？ – 2011-03-25 17:28:02

K這一個：numbers [index] = pCur.getString（pCur.getColumnIndex（ContactsContract.CommonDataKinds.Phone.NUMBER））; – mixkat 2011-03-25 17:29:55

試試這個代碼檢索聯繫人：

 ContentResolver cr1 = getContentResolver(); 
    String[] projection = new String[] {People._ID,People.NAME,People.NUMBER}; 
    Uri contacts = People.CONTENT_URI; 
    // Make the query. 
    Cursor managedCursor = cr1.query(contacts, projection, null, null, People.NAME + " ASC"); 
     if (managedCursor.moveToFirst()) { 
      String contactname; 
      String cphoneNumber; 
      int nameColumn = managedCursor.getColumnIndex(People.NAME); 
      int phoneColumn = managedCursor.getColumnIndex(People.NUMBER); 
      do { 
       // Get the field values 
       contactname = managedCursor.getString(nameColumn); 
       cphoneNumber = managedCursor.getString(phoneColumn); 
       if((cphoneNumber!= "" && cphoneNumber!=null)|| (contactname!="" && contactname!=null)){ 
        c_Name.add(contactname); 
        c_Number.add(cphoneNumber); 
       } 
      } while (managedCursor.moveToNext()); 
     }

這將retreive的姓名和號碼...

是的，我自己碰到類似的教程，但這是使用不贊成使用的API，我試圖避免這種情況！其他解決方案？ – mixkat 2011-03-25 17:29:14
