从android中的已发送列表中删除短信

Question

我正在开发Android应用程序。我需要删除发送后立即发送的短信。我尝试使用以下代码删除短信，但发送的框仍会在列表中显示此消息，但单击时不会打开。

public void sendSMS(View view){
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage("9XXXXXXXXX2", null, "CON", null, null);       
    Uri sentURI = Uri.parse("content://sms/sent/");                                 
    String[] reqCols = new String[] { "thread_id","_id", "address", "body" };
    ContentResolver cr = getContentResolver();                                  
    Cursor cursor = cr.query(sentURI, reqCols, null, null, null);
    //Cursor cursor = cr.query(sentURI, reqCols, "address like ?", new String[]{"9673479788"}, null);
    String id =null;
    String thread_id =null;
    long threadId=0;
    int count;
    if (cursor != null) {
        try {
              count = cursor.getCount();
              if (count > 0) {
                cursor.moveToFirst();
                threadId = cursor.getInt(1);                      
                System.out.println("\n THREADID : "+String.valueOf(threadId));
                Uri thread = Uri.parse("content://sms/sent/" + threadId);
                //Uri thread = Uri.parse("content://sms/sent/" + threadId);
                getContentResolver().delete(thread, null, null);
              } else{
                  System.out.println("\n NOTHING DELETED");
            }
        } finally {
                  cursor.close();
        }
    }
    System.out.println("\n THREADID : "+St`enter code here`ring.valueOf(threadId));
}

我仍然可以在已发送的框中看到该消息，但在单击时它不会打开。请帮忙。需要从已发送的短信列表中删除。
