Define Action for broadcast receivers:
private static final String TAG ="SmsService";
/**
* Message sending status broadcast
*/
private static final String ACTION_SMS_SEND = "com.SmsService.send";
/**
* Message receiving status broadcast
*/
private static final String ACTION_SMS_DELIVERY = "com.SmsService.delivery";
/**
* Message reception broadcast
*/
private static final String ACTION_SMS_RECEIVER = "android.provider.Telephony.SMS_RECEIVED";
Define and register broadcast receivers, either dynamically or statically:
class SmsReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
int resultCode = getResultCode();
if (intent.getAction().equals(ACTION_SMS_RECEIVER)){
Log.i(TAG, "SmsReceiver->onReceive");
SmsMessage sms = null;
Bundle bundle = intent.getExtras();// To obtain intent The contents of the
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");// To obtain bundle What's in there
for (Object obj : pdus) {
// The following two lines of text messages are taken and added message In the
sms = SmsMessage.createFromPdu((byte[]) obj);
}
}
mHandler.obtainMessage(MSG_SMS_RECEIVE,sms).sendToTarget();
// Receive message send status
}else if (intent.getAction().equals(ACTION_SMS_SEND)){
switch (resultCode) {
case Activity.RESULT_OK:
Log.i(TAG, " SMS sent successfully ");
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Log.i(TAG, " Text message sending failed :GENERIC_FAILURE");
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Log.i(TAG, " Text message sending failed :NO_SERVICE");
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Log.i(TAG, " Text message sending failed :NULL_PDU");
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Log.i(TAG, " Text message sending failed :RADIO_OFF");
break;
}
// Receive information receive status
}else if (intent.getAction().equals(ACTION_SMS_DELIVERY)){
switch (resultCode) {
case Activity.RESULT_OK:
Log.i(TAG, " SMS received successfully ");
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Log.i(TAG, " Message reception failed :GENERIC_FAILURE");
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Log.i(TAG, " Message reception failed :NO_SERVICE");
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Log.i(TAG, " Message reception failed :NULL_PDU");
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Log.i(TAG, " Message reception failed :RADIO_OFF");
break;
}
}
}
}
In this way, the text message automatic reply function can be realized, of course, also can realize receiving the text message automatically dial back the call. Here provides a SMS receiving function:
public void doReceiveSms(Intent intent) {
Object[] pdus = (Object[]) intent.getExtras().get("pdus");
SmsMessage [] messages = new SmsMessage[pdus.length];
for(int i=0; i<pdus.length; i++){
byte[]pdu = (byte[]) pdus[i];
// from pud Created in the 1 A message
messages[i] = SmsMessage.createFromPdu(pdu);
}
for(SmsMessage msg: messages){
// Get the content of the message
String content = msg.getMessageBody();
// Get the person who sent it
String sender = msg.getOriginatingAddress();
// Time to get text messages
long timer = msg.getTimestampMillis();
// Converts a millisecond number to a date format
Date date = new Date(timer);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-DD HH-MM-SS");
String time = sdf.format(date);
String smsContent = time + ": " + sender + ": " + content;
// Call the method that sends the SMS
sendSmsMessage("5556", smsContent);
}
}
SMS sending:
public void sendSmsMessage(String phoneNumber, String content){
SmsManager smsManager = SmsManager.getDefault();
// Determine the length of the message, if the length is greater than 70 It's going to go wrong, so this is important
if(content.length() >= 70){
List<String> list = smsManager.divideMessage(content);
for(String mMsg: list){
smsManager.sendTextMessage(phoneNumber, null, mMsg, null, null);
}
}else{
smsManager.sendTextMessage(phoneNumber, null, content, null, null);
}
}
