Android Countdown implementation

New product details, to the special sale to increase the countdown function:

Using the Countdowntimer of the Android system, this class

About the usage of this class:

* Schedule a countdown until a time in the

* Regular notifications on intervals along the.

*

* Example of showing a second countdown in a text field:

*

* <pre class= "Prettyprint" >

* New Countdowntimer (30000, 1000) {

*

* public void OnTick (long millisuntilfinished) {

* Mtextfield.settext ("seconds remaining:" + millisuntilfinished/1000);

*     }

*

* public void OnFinish () {

* Mtextfield.settext ("done!");

*     }

*}.start ();

Two methods were added to the Time tool class:

/**

* Get the countdown time interval

*

* @param datestr

* @return

*/

public static long Getcountdowninterval (String datestr) {

Long interval = 0;

if (Stringutils.isblank (DATESTR)) {

return interval;

}

Date countdowndate = new Date ();

try {

Countdowndate = Db_date_format.parse (DATESTR);

} catch (ParseException e) {

Logutils.loge ("Dateutils", "Problem with date format");

}

Date now = new Date ();

Interval = Countdowndate.gettime ()-now.gettime ();

if (Interval < 0)

return 0;

return interval;

}

/**

* @param createtime

* @return Returns the time interval from the current moment, described in Chinese form

*/

public static int[] Getcountdownintervaldetails (long intervalsec) {

int[] countdownintervaldetals = new Int[4];

Intervalsec = intervalsec/1000;//First turn into seconds

Days

int day = (int) (INTERVALSEC/(24 * 3600));

Countdownintervaldetals[0] = day;

Intervalsec = Intervalsec-day * (24 * 3600);

When

int hour = (int) (intervalsec/3600);

Countdownintervaldetals[1] = hour;

intervalsec = Intervalsec-hour * 3600;

Score of

int min = (int) (INTERVALSEC/60);

Countdownintervaldetals[2] = min;

INTERVALSEC = intervalsec-min * 60;

COUNTDOWNINTERVALDETALS[3] = (int) intervalsec;

return countdownintervaldetals;

}

Finally, assemble a control:

/**

* Countdown Control

*/

public class L_countdownblock implements Y_uiblock {

Private Context Mcontext;

Private View container;

Private Countdowntimer CDT;

Private TextView Tv_countdown_day;

Private TextView Tv_countdown_hour;

Private TextView tv_countdown_min;

Private TextView tv_countdown_sec;

protected int[] intervaldetails;

Public L_countdownblock (view view) {

This.container = view;

This.mcontext = Container.getcontext ();

}

/**

* Set End time

*

* @param datestr

*/

private void SetDate (String datestr) {

Long interval = Dateutils.getcountdowninterval (DATESTR);

CDT = new Countdowntimer (interval, 1000) {

@Override

public void OnTick (long millisuntilfinished) {

Intervaldetails = Dateutils

. Getcountdownintervaldetails (millisuntilfinished);

Tv_countdown_day.settext (Intervaldetails[0] + "");

Tv_countdown_hour.settext (Intervaldetails[1] + "");

Tv_countdown_min.settext (intervaldetails[2] + "");

Tv_countdown_sec.settext (Intervaldetails[3] + "");

}

@Override

public void OnFinish () {

TODO adds a countdown to the end of the logic

}

};

Cdt.start ();

}

/**

* Cancel Countdown

*/

private void Cancelcountdown () {

if (null! = CDT) {

Cdt.cancel ();

}

}

@Override

Public <T> void update (T t) {

Tv_countdown_day = (TextView) container

. Findviewbyid (R.id.tv_countdown_day);

Tv_countdown_hour = (TextView) container

. Findviewbyid (R.id.tv_countdown_hour);

Tv_countdown_min = (TextView) container

. Findviewbyid (R.id.tv_countdown_min);

Tv_countdown_sec = (TextView) container

. Findviewbyid (R.ID.TV_COUNTDOWN_SEC);

SetDate ((String) t);

}

@Override

Public View Getcontentview () {

return container;

}

}
