android接收和发送短信的xml配置

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-permissionandroid:name="android.permission.SEND_SMS"></uses-permission>
<uses-permissionandroid: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(Messagemsg)
??? {
??????? //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(booleanbSelfChange)
??? {
??????? 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 changingUri 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 bythread_id
? String strUriAll ="content://sms"//you can delete one message by _id
*/

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