1. send a text message and prompt for a successful delivery and whether the recipient is receiving
   
   

    Packagecom.javen.utils;Importjava.util.ArrayList;Importandroid.app.Activity;Importandroid.app.PendingIntent;ImportAndroid.content.BroadcastReceiver;ImportAndroid.content.Context;Importandroid.content.Intent;ImportAndroid.content.IntentFilter;ImportAndroid.telephony.SmsManager;ImportAndroid.widget.Toast;/** * @authorJaven **/ Public classSendmessageutil {/**send and receive broadcasts **/    Private StaticString sent_sms_action = "Sent_sms_action"; Private StaticString delivered_sms_action = "Delivered_sms_action"; /*** Implement SMS *@paramContext *@paramtext text message content *@paramPhoneNumber Mobile phone number*/     Public Static voidSendMessage (Context context, string text, String phonenumber) {Context.registerreceiver (Sendmessag E,NewIntentfilter (sent_sms_action)); Context.registerreceiver (receiver,NewIntentfilter (delivered_sms_action)); //Create the Sentintent parameterIntent sentintent =NewIntent (sent_sms_action); Pendingintent SENTPI= Pendingintent.getbroadcast (context, 0, sentintent,0); //Create the Deilverintent parameterIntent deliverintent =NewIntent (delivered_sms_action); Pendingintent Deliverpi= Pendingintent.getbroadcast (context, 0,deliverintent, 0); Smsmanager Smsmanager=Smsmanager.getdefault (); //if the word count exceeds 5, it needs to be split into multiple SMS messages.        if(Text.length () > 70) {ArrayList<String> msgs =smsmanager.dividemessage (text);  for(String msg:msgs) {smsmanager.sendtextmessage (PhoneNumber,NULL, MSG, SENTPI, Deliverpi); }        } Else{smsmanager.sendtextmessage (PhoneNumber,NULL, text, SENTPI, DELIVERPI); }    }    Private StaticBroadcastreceiver SendMessage =NewBroadcastreceiver () {@Override Public voidOnReceive (Context context, Intent Intent) {//determine if the text message was sent successfully            Switch(Getresultcode ()) { CaseActivity.RESULT_OK:Toast.makeText (Context,"SMS sent Successfully", Toast.length_short). Show ();  Break; default: Toast.maketext (Context,"Send Failed", Toast.length_long). Show ();  Break;    }        }    }; Private StaticBroadcastreceiver receiver =NewBroadcastreceiver () {@Override Public voidOnReceive (Context context, Intent Intent) {//the Fangcheng received a text message .Toast.maketext (Context, "Recipient succeeds", Toast.length_long). Show (); }    };}

   
   
2. Get SMS content via SMS database
   
   

    PackageCom.example.message;ImportJava.util.regex.Matcher;ImportJava.util.regex.Pattern;Importandroid.app.Activity;ImportAndroid.content.ContentResolver;ImportAndroid.content.Context;ImportAndroid.database.ContentObserver;ImportAndroid.database.Cursor;ImportAndroid.net.Uri;ImportAndroid.os.Bundle;ImportAndroid.os.Handler;ImportAndroid.widget.Toast; Public classMainactivityextendsActivity {PrivateSmsobserver Smsobserver; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); Smsobserver=NewSmsobserver ( This, Smshandler); Getcontentresolver (). Registercontentobserver (Sms_inbox,true, Smsobserver); }     PublicHandler Smshandler =NewHandler () {//This is where callbacks can be done.//TODO         Public voidhandlemessage (android.os.Message msg) {System.out.println ("Smshandler carried out ...");    };    }; PrivateUri Sms_inbox = Uri.parse ("content://sms/");  Public voidGetsmsfromphone () {contentresolver CR=Getcontentresolver (); string[] Projection=NewString[] {"Body", "address", "person"};//" _id", "Address",//"Person", "date" ,//the TypeString where = "date >" + (System.currenttimemillis ()-10 * 60 * 1000); Cursor cur= Cr.query (Sms_inbox, projection, where,NULL, "Date desc"); if(NULL==cur)return; if(Cur.movetonext ()) {String number= Cur.getstring (Cur.getcolumnindex ("Address"));//Phone numberString name = cur.getstring (Cur.getcolumnindex ("person"));//Contact person Name ListString BODY = cur.getstring (Cur.getcolumnindex ("Body")); System.out.println (">>>>>>>>>>>>>>>> Phone Number:" +Number ); System.out.println (">>>>>>>>>>>>>>>> Contact Name list:" +name); System.out.println (">>>>>>>>>>>>>>>> SMS Content:" +body); //here I'm going to get the verification code in my SMS service number ~ ~Pattern pattern = Pattern.compile ("[A-za-z0-9]{5}"); Matcher Matcher= Pattern.matcher (body);//String body= "Test verification Code 2346ds";            if(Matcher.find ()) {String res= Matcher.group (). substring (0, 5);//get the content of a text messageShowtoast (RES);            System.out.println (RES); }        }    }    protected voidshowtoast (String text) {Toast.maketext (mainactivity. This, text, Toast.length_long). Show (); }    classSmsobserverextendsContentobserver { PublicSmsobserver (Context context, Handler Handler) {Super(handler); } @Override Public voidOnChange (BooleanSelfchange) {            Super. OnChange (Selfchange); //whenever a new message arrives, use our method of getting a short messageGetsmsfromphone (); }    }}
