MainActivity.java的代码

packagecom.czg.com.learnsendsms;

importandroid.support.v7.app.AppCompatActivity;

importandroid.os.Bundle;

importandroid.telephony.SmsManager;

importandroid.view.View;

importandroid.widget.Button;

importandroid.widget.EditText;

importandroid.widget.Toast;

publicclassMainActivityextendsAppCompatActivity{

ButtonsendSmsBtn;

EditTexttoPhoneNumber;

EditTextsmsMessageET;

@Override

protectedvoidonCreate(BundlesavedInstanceState){

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

sendSmsBtn=(Button)findViewById(R.id.btnSendSMS);

toPhoneNumber=(EditText)findViewById(R.id.editTextPhoneNo);

smsMessageET=(EditText)findViewById(R.id.editTextSMS);

sendSmsBtn.setOnClickListener(newView.OnClickListener(){

@Override

publicvoidonClick(Viewv){

sendSms();

}

});

}

privatevoidsendSms(){

StringtoPhone=toPhoneNumber.getText().toString();

StringsmsMessage=smsMessageET.getText().toString();

try{

SmsManagersmsManager=SmsManager.getDefault();

smsManager.sendTextMessage(toPhone,null,smsMessage,null,null);

Toast.makeText(this,"短信已发送",Toast.LENGTH_LONG).show();

}catch(Exceptione){

e.printStackTrace();

}

}

}

创建一个SmsBroadcastReceiver广播接收器用于接收系统发出收到短信的广播

SmsBroadcastReceiver.java

packagecom.czg.com.learnsendsms;

importandroid.content.BroadcastReceiver;

importandroid.content.Context;

importandroid.content.Intent;

importandroid.os.Bundle;

importandroid.telephony.SmsMessage;

importandroid.widget.Toast;

importjava.text.SimpleDateFormat;

importjava.util.Date;

/**

*CreatedbyAdministratoron2016/1/22.

*/

publicclassSmsBroadcastReceiverextendsBroadcastReceiver{

publicstaticfinalStringSMS_BUNDLE="pdus";

@Override

publicvoidonReceive(Contextcontext,Intentintent){

BundleintentExtras=intent.getExtras();

if(intentExtras!=null){

Object[]sms=(Object[])intentExtras.get(SMS_BUNDLE);

StringsmsMessageStr="";

for(inti=0;i<sms.length;i++){

SmsMessagesmsMessage=SmsMessage.createFromPdu((byte[])sms[i]);

StringsmsBody=smsMessage.getMessageBody().toString();

Stringaddress=smsMessage.getOriginatingAddress();

longtimeMillis=smsMessage.getTimestampMillis();

Datedate=newDate(timeMillis);

SimpleDateFormatformat=newSimpleDateFormat("dd/MM/yy");

StringdateText=format.format(date);

smsMessageStr+=address+"at"+"\t"+dateText+"\n";

smsMessageStr+=smsBody+"\n";

}

Toast.makeText(context,smsMessageStr,Toast.LENGTH_SHORT).show();

}

}

}
