短信程序不断向同一个电话号码发送相同的内容

Question

我必须执行一个计划短信程序，一切正常，除了唯一的一个：在我第二次尝试发送短信时，该程序将与第一次相同的内容发送到与第一次相同的电话号码第一次。 这是我的代码：

main_activity, sendBtn:

sendBtn.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            try { 
                Intent myIntent = new Intent(main_activity.this, MyAlarmService.class);

                String smsNumber = phoneNo.getText().toString();
                String smsText = edit.getText().toString();

                if (smsNumber.length() != 0 && smsText.length() != 0){


                    Bundle bundle = new Bundle();
                    bundle.putCharSequence("extraSmsNumber", smsNumber);
                    bundle.putCharSequence("extraSmsText", smsText);
                    myIntent.putExtras(bundle);
                    String text = mTimeDisplay.getText().toString() + " " + mDateDisplay.getText().toString();


                    DateFormat formatter ; 
                    Date date ; 
                    formatter = new SimpleDateFormat("HH:mm dd/MM/yyyy");
                    date = (Date)formatter.parse(text);


                    Calendar setCalendar = Calendar.getInstance();
                    setCalendar.setTime(date);


                    pendingIntent = PendingIntent.getService(main_activity.this, 0, myIntent, 0);

                    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

                    Calendar calendar = Calendar.getInstance();                

                    calendar.setTimeInMillis(System.currentTimeMillis());
                    alarmManager.set(AlarmManager.RTC_WAKEUP, setCalendar.getTimeInMillis(), pendingIntent);

                    Toast.makeText(main_activity.this,
                            "Start Alarm with \n" +
                            "smsNumber = " + smsNumber + "\n" +
                            "smsText = " + smsText + "\n Contain : " + text,
                            Toast.LENGTH_LONG).show();

                }
                else {
                    showDialog(ALERT_DIALOG_ID);
                }
            }
            catch (ParseException e)
            {Toast.makeText(main_activity.this,"Error!!!",Toast.LENGTH_LONG).show();    }
        }
    }
    );

MyAlarmService:

import android.app.Service;
import android.content.Intent;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.SmsManager;
import android.widget.Toast;

public class MyAlarmService extends Service {

String smsNumberToSend, smsTextToSend;

@Override
public void onCreate() {
    // TODO Auto-generated method stub

    Toast.makeText(this, "MyAlarmService.onCreate()", Toast.LENGTH_LONG).show();
}

@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    Toast.makeText(this, "MyAlarmService.onBind()", Toast.LENGTH_LONG).show();
    return null;
}

@Override
public void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    Toast.makeText(this, "MyAlarmService.onDestroy()", Toast.LENGTH_LONG).show();
}

@Override
public void onStart(Intent intent, int startId) {
    // TODO Auto-generated method stub
    super.onStart(intent, startId);

    Bundle bundle = intent.getExtras();
    smsNumberToSend = (String) bundle.getCharSequence("extraSmsNumber");
    smsTextToSend = (String) bundle.getCharSequence("extraSmsText");

    sendSMS(smsNumberToSend, smsTextToSend);
}

private void sendSMS(String phoneNumber, String message)
{   
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);    

}

@Override
public boolean onUnbind(Intent intent) {
    // TODO Auto-generated method stub
    Toast.makeText(this, "MyAlarmService.onUnbind()", Toast.LENGTH_LONG).show();
    return super.onUnbind(intent);
}

}

我真的需要帮助，请帮助我尽快找到解决方案，非常感谢

您的问题在于：

pendingIntent = PendingIntent.getService(main_activity.this, 0, myIntent, 0);

首先您需要添加一个标志，以便创建的 PendingIntent 不会每次都被重用。

然后你需要添加一些唯一的请求代码，如果没有，之前的PendingIntent将被取消并替换。即，如果您安排发送两条短信，则只会发送最后一条。

pendingIntent = PendingIntent.getService(main_activity.this, SOMETHING_UNIQUE, myIntent, PendingIntent.FLAG_ONE_SHOT);
