I am working on an ANdroid application.In my app I have to list all the conversations and i did that part.Each conversation is containing all sms to that number. So i have to differtiate inbox and sentsms from all sms.I know about the following api's can use to find inbox and sent.

content://sms/inbox
content://sms/sent

但我不希望使用的API来使用this.I列出的所有短信

But i don't want to use this.I listed all sms by using the api

content://sms/

I tested with the columnindex's type,address but it always gives the same result for inbox and outbox.And my sample code is

Uri SMS_INBOX = Uri.parse("content://sms");
        c = getContentResolver().query(SMS_INBOX, null, "thread_id" + " = "
                        + "3", null,
                        "date" + " ASC");
        if(c.moveToFirst()){
            count.add(c.getCount());
            for(int j=0;j<c.getCount();j++){
                System.out.println(c.getString(c.getColumnIndexOrThrow("body")).toString());
                System.out.println("new   person=="+c.getColumnIndex("person")+"type=="+c.getColumnIndexOrThrow("type"));
                c.moveToNext();
            }
        }
        c.close();

请帮我。

推荐答案

您可以使用ContentObserver这里来跟踪发送和接收消息，

You can use ContentObserver here to track sent and received message,

ContentObserver 的覆盖的onChange（）方法，并得到短信类型和相应的工作。伪code可以如下图所示。

Override onChange() method of ContentObserver and get the sms type and work accordingly. Psuedo code can be as below.

Cursor cursor = mContext.getContentResolver().query(Uri
                             .parse("content://sms"), null, null, null, null);

String type = cursor.getColumnIndex("type");
if(cursor.getString(type).equalsIgnoreCase("1")){
    // sms received
 }
 else if(cursor.getString(type).equalsIgnoreCase("2")){
    //sms sent
 }

注册 ContentObserver 短信，

ContentResolver observer = this.getContentResolver();
observer.registerContentObserver(Uri.parse("content://sms"), 
                               true, new MySMSObserver(new Handler(),this));

其中， MySMSObserver 将是你的类扩展 ContentObserver 与构造具有参数作为处理程序和上下文，

Where MySMSObserver will be your class extending ContentObserver with Constructor having argument as Handler and Context,

public MySMSObserver(Handler handler, Context context) {
        super(handler);
        this.context = context;
}
