Android標準Timer和標準LOGFile的MVC架構寫法

Timer(透過m_intID來分辨哪個UI並執行對應TIMER，不但可把所有控制寫在一起但UI又可獨立工作不互相干擾)MVC–>C
LOGFile(具有時間序的標準記錄方式)MVC–>M

MVC—>V

package com.example.android_timer_logfile;

import com.UITimer;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.widget.TextView;
//MVC——->V
public class MainActivity extends Activity {
   public UITimer m_Timer;
   public TextView m_TV01;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       m_TV01=(TextView)this.findViewById(R.id.textView1);
       m_Timer=new UITimer((Context)this,1000,0);
       m_Timer.SetTimer();
   }

   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
       // Inflate the menu; this adds items to the action bar if it is present.
       getMenuInflater().inflate(R.menu.main, menu);
       return true;
   }

}

MVC—>C

package com;
import java.util.Calendar;

import com.example.android_timer_logfile.MainActivity;
//MVC——->C
import android.content.Context;
import android.os.Handler;

public class UITimer {
   public Handler m_HandlerTimer;
   public Context m_Context;
   public int m_intID;
   public int m_intSleep;
   public void MainActivity_fun1()
   {
       MainActivity Ma=(MainActivity)m_Context;

Calendar dt = Calendar.getInstance();
int thisYear = dt.get(Calendar.YEAR);
int thisMonth = dt.get(Calendar.MONTH)+1;
int thisDate = dt.get(Calendar.DAY_OF_MONTH);
int thisHour = dt.get(Calendar.HOUR_OF_DAY);
int thisMin = dt.get(Calendar.MINUTE);
int thisSec = dt.get(Calendar.SECOND);
       Ma.m_TV01.setText(Integer.toString(thisHour)+”:” + Integer.toString(thisMin)+”:” + Integer.toString(thisSec));

       String FileName = String.format(“%d%02d%02d.log”, thisYear,thisMonth,thisDate);
       LogFile.WriteData2File(“ATL”, FileName, “Timer_Run”);

       SetTimer();
   }
   private final Runnable TimerRun = new Runnable()
   {
       public void run()
       {
           if(m_intID==0)
           {
               MainActivity_fun1();
           }
       }
   };
   public void SetTimer()
   {
       m_HandlerTimer.postDelayed(TimerRun, m_intSleep);//啟動Timer
   }
   public UITimer(Context Context,int sleep,int ui)
   {
       m_intID=ui;
       m_Context=Context;
       m_intSleep=sleep;
       m_HandlerTimer=new Handler();
       LogFile.CreateAppFloder(“ATL”);
   }
}

MVC—>M

package com;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
//MVC——->M
import android.os.Environment;

public class LogFile {
   public static void CreateAppFloder(String StrDir) // 建立APP 資料夾
   {
       File sd=Environment.getExternalStorageDirectory();
       String path=sd.getPath()+”/”+StrDir;
       File floder=new File(path);
       String logpath=sd.getPath()+”/”+StrDir+”/”+StrDir+”.log”;
       File logfile=new File(logpath);
       if(!floder.exists())
       {
           floder.mkdir();
       }
       else
       {
           if(logfile.exists())
           {
               logfile.delete();
           }
       }

   }
   public static void WriteData2File(String StrDir,String FileName,String StrMsg)//
   {

       File sd=Environment.getExternalStorageDirectory();
       String Dir=StrDir;
       CreateAppFloder(Dir);
       String logpath=sd.getPath()+”/”+Dir+”/”+FileName;
       try
       {
           FileWriter out = new FileWriter(logpath,true);

       SimpleDateFormat formatter;
       formatter = new SimpleDateFormat (“HH:mm:ss”);
       Calendar cal = Calendar.getInstance();
       String ctime = formatter.format(cal.getTime());
       StrMsg=ctime+”_”+StrMsg;

       out.write((StrMsg+”\n”));
           out.close();
       }
       catch(IOException ioe){
           System.out.print(ioe);
       }
   }
}
