Android設定アラームでアクティビティの特定の部分を実行する

Question

私はJavaを初めて使いました。これは私の最初の投稿ですので、誰かが助けてくれることを願っています。私は運がないとこれに対する答えを見つけるためにGoogleに来たすべてのウェブサイトをチェックした。だから私は設定された時間から24時間ごとに乱数を生成する繰り返しアラームを設定しようとしています。私はアラームマネージャを使用しており、アラームマネージャを使用してアクティビティやサービスを開始するコード例しか見つからないようです。私がしたいのは、すでにアクティビティの中にある単純なコマンドを実行するためにアラームマネージャを使用することです。ここで

は私が持っているものの一例であり、私がやりたいすべてがgenerateNumber（）メソッドを呼び出して何イム

import java.util.Calendar; 
import java.util.Random; 
import android.app.Activity; 
import android.app.AlarmManager; 
import android.app.PendingIntent; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 

public class ExampleCode extends Activity 
{ 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.example); 

     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);   // Here I want to set an alarm  

     Calendar twentyFourHourCalendar = Calendar.getInstance();  


     twentyFourHourCalendar.set(Calendar.HOUR_OF_DAY, 24);         // At midnight 
     twentyFourHourCalendar.set(Calendar.MINUTE, 0); 
     twentyFourHourCalendar.set(Calendar.SECOND, 0); 

     Intent someIntent = new Intent("com.example.SomeOtherProcess");      // Instead of an activity I want it to run the generateRandom() method below 

     someIntent.putExtra("NotifID", 1);         

     PendingIntent displayIntent = PendingIntent.getActivity(
      getBaseContext(), 0, someIntent, 0);    

     alarmManager.set(AlarmManager.RTC_WAKEUP, 
       twentyFourHourCalendar.getTimeInMillis(), displayIntent); 

     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, twentyFourHourCalendar    // I want it to generate a random number every midnight without any user interaction 
       .getTimeInMillis(), 24 * 60 * 60 * 1000, displayIntent);   

    } 



    public void generateRandom()                // This is the method that I want to repeat 
    { 
     Random generator = new Random(); 
      int randomNumber = generator.nextInt(2); 
    } 



    } 

を達成しようとしている（これを行うにはtheresの別の方法場合は私に知らせてください） 24時間ごとにソリューションが非常にシンプルであると確信しています。私はコードを見て長すぎてLOLを理解できないと思います。どんな助けでも大歓迎です!!!
