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
