我开发，将存储所有传入和传出的短信在SD卡上的文本文件的应用程序。

I am developing an application which will store all the incoming and outgoing sms in a text file in SD card.

我能听使用广播接收传入的消息。我发现很难听传出的短信。

I am able to listen incoming messages using broadcast receiver. I am finding it very difficult to listen to outgoing SMS.

我知道，在一定程度上，需要在发件箱或者发件箱内容观察员进行设置，但我不知道该怎么做。

I know to some extent that a content observer on the sent box or outbox needs to be set, but I don't know how to do it.

如何才能做到这一点？

推荐答案

基本上，你必须注册内容的观察者......是这样的：

Basically, you have to register a content observer... something like this:

ContentResolver contentResolver = context.getContentResolver(); contentResolver.registerContentObserver(Uri.parse("content://sms/out"),true, yourObserver);

yourObserver 是一个对象（新YourObserver（新处理器（）））可能是这样的：

yourObserver is an object (new YourObserver(new Handler())) that could look like this:

class YourObserver extends ContentObserver { public YourObserver(Handler handler) { super(handler); } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); // save the message to the SD card here } }

那么，究竟你明白了短信的内容？您必须使用光标：

// save the message to the SD card here Uri uriSMSURI = Uri.parse("content://sms/out"); Cursor cur = this.getContentResolver().query(uriSMSURI, null, null, null, null); // this will make it point to the first record, which is the last SMS sent cur.moveToNext(); String content = cur.getString(cur.getColumnIndex("body")); // use cur.getColumnNames() to get a list of all available columns... // each field that compounds a SMS is represented by a column (phone number, status, etc.) // then just save all data you want to the SDcard :)
