Android 接受短信和发送短信

1.android发送短信
android API 中提供了smsManager类处理短信。其中的sendTextMessage(num, null, content, pend, null)函数就是发送
短信的方法。第一个参数为目标者手机号、第二个参数为短信中心地址 null为默认地址、
第三个参数短信的文本内容、第四个参数是一个intent会把发送结果带回。第五个参数不知，一般为null。

一个应用程序要具备发送短信功能，需要在androidManifest.xml中加入android.permission.SEND_SMS权限。

在模拟器中发送中文会接收方出现乱码的问题，但是在真机中，就不会出现乱码的情况了。所以
开发者只需要正常开发短信功能，不需要编码转换。

接收短信也是比较方便的，主要是继承BroadcaseReceiver 类 ,覆盖onReceive 函数：

1:相关类：
android.content.BroadcastReceiver
android.telephony.gsm.SmsMessage;

2:example code.

public class MessageDemo extends BroadcastReceiver {
private static final String strACT = "android.provider.Telephony.SMS_RECEIVED";

public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(strACT)) {
StringBuilder sb = new StringBuilder();
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] msg = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
for (SmsMessage currMsg : msg) {
sb.append("From:");
sb.append(currMsg.getDisplayOriginatingAddress());
sb.append("\nMessage:");
sb.append(currMsg.getDisplayMessageBody());
}
}
}

}
}
3: 相关的配置

修改AndroidManifest.xml，在Activity下添加receiver节点：
<receiver android:name="MessageDemo">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
随后在application下添加节点：
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

4:使用BroadReceiver的弊端
查看BroadReceiver sdk reference , 可以了解到所有的BroadReceiver对短信的接收是无顺序的状态，即使是使用了Ordered broadcasts对于同等优先级别的BroadReceiver ,也会产生无顺序的行为。
所以下面介绍另一种接收短信的行为，包括其中可以进行短信的删除。

5：从数据库端监听sms的收发
//如下主要用于内部数据库改变，向外面的界面(Activity)做反应
class SMSHandler extends Handler
{
public void handleMessage(Message msg)
{
//Handle message
}
}

// 对收到短消息后，做出的处理,这里直接删除，并没有反应到界面，所以上面的handleMessage是空的。
class SMSObserver extends ContentObserver
{
private Handler m_handle = null;

public SMSObserver(Handler handle)
{
super(handle);
m_handle = handle;
}

public void onChange(boolean bSelfChange)
{
super.onChange(bSelfChange);

//Send message to Activity
Message msg = new Message();
msg.obj = "xxxxxxxxxx";
m_handle.sendMessage(msg);

String strUriInbox = "content://sms/inbox";
Uri uriSms = Uri.parse(strUriInbox); //If you want to access all SMS, just replace the uri string to "content://sms/"
Cursor c = mContext.getContentResolver().query(uriSms, null, null, null, null);
// delete all sms here when every new sms occures.
while (c.moveToNext())
{
//Read the contents of the SMS;
for(int i; i < c.getColumnCount(); i++)
{
String strColumnName = c.getColumnName(i);
String strColumnValue = c.getString(i);
}

//Delete the SMS
String pid = c.getString(1); //Get thread id;
String uri = "content://sms/conversations/" + pid;
mContext.getContentResolver().delete(Uri.parse(uri), null, null);

}

}
}

//把基本类功能性地应用起来
ContentResolver contentResolver = getContentResolver();// Context 环境下getContentResolver()
Handler handler = new SMSHandler();
ContentObserver m_SMSObserver = new SMSObserver(handler);
contentResolver.registerContentObserver(Uri.parse("content://sms/inbox"),true, m_SMSObserver);
//Register to observe SMS in outbox,we can observe SMS in other location by changing Uri string, such as inbox, sent, draft, outbox, etc.)

// some Available Uri string for sms.
/*
String strUriInbox = "content://sms/inbox";//SMS_INBOX:1
String strUriFailed = "content://sms/failed";//SMS_FAILED:2
String strUriQueued = "content://sms/queued";//SMS_QUEUED:3
String strUriSent = "content://sms/sent";//SMS_SENT:4
String strUriDraft = "content://sms/draft";//SMS_DRAFT:5
String strUriOutbox = "content://sms/outbox";//SMS_OUTBOX:6
String strUriUndelivered = "content://sms/undelivered";//SMS_UNDELIVERED
String strUriAll = "content://sms/all";//SMS_ALL
String strUriConversations = "content://sms/conversations";//you can delete one conversation by thread_id
String strUriAll = "content://sms"//you can delete one message by _id
*/

REMEBER: must request following permission
1) Read SMS
<uses-permssion android:name="android.permission.READ_SMS" />
2) Delete/Modify/Send SMS
<uses-permssion android:name="android.permission.WRITE_SMS" />
in AndroidManifest.xml

Android数据库总结：

短信数据库
String strUriInbox = "content://sms";
Uri uriSms = Uri.parse(strUriInbox);
Cursor c_groups = managedQuery( uriSms , new String[] { "date","person" }, select, null, "date DESC");

strColumnName=_id strColumnValue=48 //短消息序号
strColumnName=thread_id strColumnValue=16 //对话的序号（conversation）
strColumnName=address strColumnValue=+8610086 //发件人地址，手机号
strColumnName=person strColumnValue=null //发件人，返回一个数字就是联系人列表里的序号，陌生人为null
strColumnName=date strColumnValue=1256539464222 //日期 long型，想得到具体日期自己转换吧！
