copied!<p>Here a simple clock i developed using methods used in android native DigitalClock.java and AnalogClock.Java classes.<strong>this clock supports for events that triggered for each second or minute</strong>,so you can use those events and run your code.</p> <blockquote> <ol> <li>StartTickPerSecond() method uses the method used in DigitalClock.java to get the tick per second.</li> <li>StartTickPerMinute() method uses the method used in AnalogClock.java to get the tick per minute</li> </ol> </blockquote> <p>this still may require some modifications..but hope this will be something you to start with.. <br> <br> <strong>Clock.java</strong></p> <pre><code>package com.sample.data; import java.util.*; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.content.IntentFilter; import android.os.Handler; import android.os.SystemClock; import android.text.format.Time; public class Clock { public static final int TICKPERSECOND=0; public static final int TICKPERMINUTE=1; private Time Time; private TimeZone TimeZone; private Handler Handler; private List<OnClockTickListner> OnClockTickListenerList = new ArrayList<OnClockTickListner>(); private Runnable Ticker; private BroadcastReceiver IntentReceiver; private IntentFilter IntentFilter; private int TickMethod=0; Context Context; public Clock(Context context) { this(context, Clock.TICKPERMINUTE); } public Clock(Context context,int tickMethod) { this.Context=context; this.TickMethod=tickMethod; this.Time=new Time(); this.Time.setToNow(); switch (TickMethod) { case 0: this.StartTickPerSecond(); break; case 1: this.StartTickPerMinute(); break; default: break; } } private void Tick(long tickInMillis) { Clock.this.Time.set(Clock.this.Time.toMillis(true)+tickInMillis); this.NotifyOnTickListners(); } private void NotifyOnTickListners() { switch (TickMethod) { case 0: for(OnClockTickListner listner:OnClockTickListenerList) { listner.OnSecondTick(Time); } break; case 1: for(OnClockTickListner listner:OnClockTickListenerList) { listner.OnMinuteTick(Time); } break; } } private void StartTickPerSecond() { this.Handler=new Handler(); this.Ticker = new Runnable() { public void run() { Tick(1000); long now = SystemClock.uptimeMillis(); long next = now + (1000 - now % 1000); Handler.postAtTime(Ticker, next); } }; this.Ticker.run(); } private void StartTickPerMinute() { this.IntentReceiver= new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Tick(60000); } }; this.IntentFilter = new IntentFilter(); this.IntentFilter.addAction(Intent.ACTION_TIME_TICK); this.Context.registerReceiver(this.IntentReceiver, this.IntentFilter, null, this.Handler); } public void StopTick() { if(this.IntentReceiver!=null) { this.Context.unregisterReceiver(this.IntentReceiver); } if(this.Handler!=null) { this.Handler.removeCallbacks(this.Ticker); } } public Time GetCurrentTime() { return this.Time; } public void AddClockTickListner(OnClockTickListner listner) { this.OnClockTickListenerList.add(listner); } } </code></pre> <p><strong>OnClockTickListner.java</strong></p> <pre><code>public interface OnClockTickListner { public void OnSecondTick(Time currentTime); public void OnMinuteTick(Time currentTime); } </code></pre> <p><strong>How to use</strong></p> <pre><code>public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.clock_list_item); Clock c=new Clock(this); c.AddClockTickListner(new OnClockTickListner() { @Override public void OnSecondTick(Time currentTime) { Log.d("Tick Test per Second",DateFormat.format("h:mm:ss aa ", currentTime.toMillis(true)).toString()); } @Override public void OnMinuteTick(Time currentTime) { Log.d("Tick Test per Minute",DateFormat.format("h:mm aa", currentTime.toMillis(true)).toString()); } }); } } </code></pre>
