选择从联系人列表中的联系人崩溃的应用程序

Question

我想从我的联系人列表中我的应用程序中的联系人：

public void selecionar_contato(View view) { 
     Intent intent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI); 
     startActivityForResult(intent, CONTACT_PICKER_RESULT); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

     if (resultCode == RESULT_OK) { 
      switch (requestCode) { 
      case CONTACT_PICKER_RESULT: 
       Uri dados = data.getData(); 
       Cursor c = getContentResolver().query(dados, new String[]{ 
         ContactsContract.CommonDataKinds.Phone.NUMBER, 
         ContactsContract.CommonDataKinds.Phone.TYPE }, null, null, null); 
       if(c.moveToFirst()){ 
        String num = c.getString(0); 
        int type = c.getInt(1); 
        mostarToast(type,num); 
       } 
       break; 
      } 

     } else { 
      // gracefully handle failure 
      Log.w("Erro", "Warning: ac"); 
     } 
    } 

    private void mostarToast(int type, String num) { 
     Toast.makeText(this, type + ": " + num, Toast.LENGTH_LONG).show(); 

    } 

但是，当我选择联系人，我的应用程序崩溃：

09-21 17:44:40.897: E/AndroidRuntime(17432): FATAL EXCEPTION: main 
09-21 17:44:40.897: E/AndroidRuntime(17432): Process: com.example.pacixmobile, PID: 17432

我必须覆盖onActivityResult方法吗？我错过了什么？

Answer 1

您请求的列不能直接用于您正在使用的Uri。您选择了一个联系人。你还没有选择一个电话号码。联系人可能有零个，一个或多个电话号码。

鉴于Uri摘自ContactsContract.Contacts，您可以检索列available on ContactsContract.Contacts。

Answer 2

我有这个在一个活动，它的工作正常，在手机和平​​板电脑测试。 我首先得到选择的内容，然后是她/他的电话号码。我需要一个手机号码，如果它存在的话，它也是9位数（西班牙号码），去掉+34或任何国家代码。

    long contactId = -1; 
    // get display name from the contact

        null); 
     if (cursor.moveToFirst()) 
     { 
      String name = cursor.getString(1);

      }

    finally 
    {

    } 
}
