接收短信起步相应服务

接收短信启动相应服务
1.首先是在配置文件中申明一个Receiver:
 

 <receiver android:name=".SMSReceiver" android:enabled="true">
 <intent-filter>
 <action android:name="android.provider.Telephony.SMS_RECEIVED" />
 </intent-filter>
 </receiver>

2.实现继承BroadcastReceiver的类:
 

public class SMSReceiver extends BroadcastReceiver {
	/* 当收到短信时，就会触发此方法 */
	public void onReceive(Context context, Intent intent) {
		Bundle bundle = intent.getExtras();
		Object messages[] = (Object[]) bundle.get("pdus");
		SmsMessage smsMessage[] = new SmsMessage[messages.length];
		for (int n = 0; n < messages.length; n++) {
			smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
		}
		// 产生一个Toast
		Toast toast = Toast.makeText(context,
				"短信内容wewewewew: " + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG);
		// 设置toast显示的位置
		// toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 200);
		// 显示该Toast
		toast.show();
	}
}
