Android - 查询 SMS ContentProvider？

Question

我目前在以下 URI“content://sms/”上注册了一个内容观察器，以监听正在发送的传入和传出消息。

这似乎工作正常，我也尝试从短信数据库中删除，但我只能从以下 URI“content://sms/conversations/”中删除整个线程

这是我使用的代码

String url = "content://sms/"; 
        Uri uri = Uri.parse(url); 
        getContentResolver().registerContentObserver(uri, true, new MyContentObserver(handler));                    

}

class MyContentObserver extends ContentObserver { 

    public MyContentObserver(Handler handler) { 

        super(handler); 

    }

@Override public boolean deliverSelfNotifications() { 
    return false; 
    }

@Override public void onChange(boolean arg0) { 
    super.onChange(arg0);

     Log.v("SMS", "Notification on SMS observer"); 

    Message msg = new Message(); 
    msg.obj = "xxxxxxxxxx";

    handler.sendMessage(msg);

    Uri uriSMSURI = Uri.parse("content://sms/");
    Cursor cur = getContentResolver().query(uriSMSURI, null, null,
                 null, null);
    cur.moveToNext();
    String protocol = cur.getString(cur.getColumnIndex("protocol"));
    if(protocol == null){
           Log.d("SMS", "SMS SEND"); 
           int threadId = cur.getInt(cur.getColumnIndex("thread_id"));

           Log.d("SMS", "SMS SEND ID = " + threadId); 
           Cursor c = getContentResolver().query(Uri.parse("content://sms/outbox/" + threadId), null, null,
                   null, null);
           c.moveToNext();
           int p = cur.getInt(cur.getColumnIndex("person"));
           Log.d("SMS", "SMS SEND person= " + p); 
           //getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadId), null, null);

    }
    else{
        Log.d("SMS", "SMS RECIEVE");  
         int threadIdIn = cur.getInt(cur.getColumnIndex("thread_id"));

         getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadIdIn), null, null);
    }

 }


} 

但是我希望能够从 SMS Content Provider 获取接收者和消息文本，谁能告诉我该怎么做？

还有如何删除一条消息而不是整个线程？

Answer 1

这已经讨论过了。

要从内容提供者检查读取短信: - android-1-5-reading-sms-messages

检查这个线程:

• delete-sms-in-android-1-5
• how-to-delete-sms-from-inbox-in-android-programmatically
• can-we-delete-an-sms-in-android-before-it-reaches-the-inbox

关于您说您要删除整个线程而不是单个短信的评论:你试过了吗this code ？
