从您的联系人列表中获取号码

Question

我正在尝试通过Intent访问我的联系人列表以获取号码，但我正在创建一个例外。

java.lang.IllegalStateException：无法从CursorWindow读取行0，col -1。在从中访问数据之前，确保Cursor已正确初始化。

这是我的代码：

// In some function 
     Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); 
     startActivityForResult(intent, Constants.PICK_CONTACT); 
    } 

    public void onActivityResult (int requestCode, int resultCode, Intent data) { 
    Cursor cursor = null; 
    if (resultCode == RESULT_OK && requestCode == Constants.PICK_CONTACT){ 
     try { 

      Uri contactData = data.getData(); 
      Cursor c = getContentResolver().query(contactData, null, null, null, null); 
      if (c.moveToFirst()) { 
       String number = c.getString(c.getColumnIndex(ContactsContract.PhoneLookup.NUMBER)); 
       // do some stuff 
      } 
     } catch (Exception e) { 
      StringWriter errors = new StringWriter(); 
      e.printStackTrace(new PrintWriter(errors)); 
      Log.i("Excepetion", errors.toString()); 
     } finally { 
      if (cursor != null) { 
       cursor.close(); 
      } 
     } 
    } 
} 

堆栈跟踪为这一个：

Answer 1

事情是，我见过的热代码工作，但所有的联系人都显示出来，我只需要选中。在这里，同样的问题，该代码为我工作：

Get selected phone number from contacts list without READ_CONTACTS permission

Answer 2

首先，确保你选择一个联系人的联系number.This可以通过将完成android.provider.ContactsContract.Contacts.HAS_PHONE_NUMBER有关resolver.query（）的第三个参数。

其次尝试ContactsContract.CommonDataKinds.Phone.NUMBER代替ContactsContract.PhoneLookup.NUMBER。
