最近有个需求,不去调用系统界面发送彩信功能。做过发送短信功能的同学可能第一反应是这样:
不使用 StartActivity,像发短信那样,调用一个类似于发短信的方法
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneCode, null, text, null, null);
可以实现吗? 答案是否定的,因为android上根本就没有提供发送彩信的接口,如果你想发送彩信,对不起,请调用系统彩信app界面,如下:
Java代码
Intent sendIntent = new Intent(Intent.ACTION_SEND, Uri.parse("mms://"));
sendIntent.setType("image/jpeg");
String url = "file://sdcard//tmpPhoto.jpg";
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url));
startActivity(Intent.createChooser(sendIntent, "MMS:"));
Intent sendIntent = new Intent(Intent.ACTION_SEND, Uri.parse("mms://"));
sendIntent.setType("image/jpeg");
String url = "file://sdcard//tmpPhoto.jpg";
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url));
startActivity(Intent.createChooser(sendIntent, "MMS:"));
但是这种方法往往不能满足我们的需求,能不能不调用系统界面,自己实现发送彩信呢?经过几天的努力,终于找到了解决办法。
第一步:先构造出你要发送的彩信内容,即构建一个pdu,需要用到以下几个类,这些类都是从android源码的MMS应用中mms.pdu包中copy出来的。你需要将pdu包中的所有类
都拷贝到你的工程中,然后自己酌情调通。
Java代码
final SendReq sendRequest = new SendReq();
final PduBody pduBody = new PduBody();
final PduPart part = new PduPart();//存放附件,每个附件是一个part,如果添加多个附件,就想body中add多个part。
pduBody.addPart(partPdu);
sendRequest.setBody(pduBody);
final PduComposer composer = new PduComposer(ctx, sendRequest);
final byte[] bytesToSend = composer.make(); //将彩信的内容以及主题等信息转化成byte数组,准备通过http协议//发送到 ”http://mmsc.monternet.com”;
final SendReq sendRequest = new SendReq();
final PduBody pduBody = new PduBody();
final PduPart part = new PduPart();//存放附件,每个附件是一个part,如果添加多个附件,就想body中add多个part。
pduBody.addPart(partPdu);
sendRequest.setBody(pduBody);
final PduComposer composer = new PduComposer(ctx, sendRequest);
final byte[] bytesToSend = composer.make(); //将彩信的内容以及主题等信息转化成byte数组,准备通过http协议//发送到 ”http://mmsc.monternet.com”;
第二步:发送彩信到彩信中心。
构建pdu的代码:
Java代码
String subject = "测试彩信";
String recipient = "接收彩信的号码";//138xxxxxxx
final SendReq sendRequest = new SendReq();
final EncodedStringValue[] sub = EncodedStringValue.extract(subject);
if (sub != null && sub.length > 0) {
sendRequest.setSubject(sub[0]);
}
final EncodedStringValue[] phoneNumbers = EncodedStringValue.extract(recipient);
if (phoneNumbers != null && phoneNumbers.length > 0) {
sendRequest.addTo(phoneNumbers[0]);
}
final PduBody pduBody = new PduBody();
final PduPart part = new PduPart();
part.setName("sample".getBytes());
part.setContentType("image/png".getBytes());
String furl = "file://mnt/sdcard//1.jpg";
final PduPart partPdu = new PduPart();
partPdu.setCharset(CharacterSets.UTF_8);//UTF_16
partPdu.setName(part.getName());
partPdu.setContentType(part.getContentType());
partPdu.setDataUri(Uri.parse(furl));
pduBody.addPart(partPdu);
sendRequest.setBody(pduBody);
final PduComposer composer = new PduComposer(ctx, sendRequest);
final byte[] bytesToSend = composer.make();
Thread t = new Thread(new Runnable() {
@Override
public void run() {
try {
HttpConnectInterface.sendMMS(ctx, bytesToSend);
//
} catch (IOException e) {
e.printStackTrace();
}
}
});
t.start();
发送pdu到彩信中心的代码:

至此,彩信的发送算是完成了。
总结:android的彩信相关操作都是没有api的,包括彩信的读取、发送、存储。这些过程都是需要手动去完成的。想要弄懂这些过程,需要仔细阅读android源码中的mms这个app。还有就是去研究mmssms.db数据库,因为彩信的读取和存储其实都是对mmssms.db这个数据库的操作过程。而且因为这个是共享的数据库,所以只能用ContentProvider这个组件去操作db。
总之,想要研究彩信这块(包括普通短信),你就必须的研究mmssms.db的操作方法,多多了解每个表对应的哪个uri,每个uri能提供什么样的操作,那些字段代表短信的那些属性等。
最后推荐个好用的sqlite查看工具:SQLite Database Browser。
