這裏我找到輸入日期和當前日期之間的差異。我的意思是我試圖找到兩個日期之間的天數。如果兩個日期都在同一個月內,如果日期在不同的月份,我會得到正確的值,但差異值不正確。我沒有得到如何糾正這一問題。Android中當前日期和輸入日期之間的差異
任何人都可以幫助我得到這個嗎?
這是我的代碼:
public class MyService extends Service {
String dayDifference;
NotificationManager manager;
Notification myNotication;
@Override public IBinder onBind(Intent intent) {
return null;
}//End of onBind method
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
try {
//Dates to compare
String CurrentDate;
String FinalDate = "08/24/2016";
Date date1 = new Date();
Date date2;
SimpleDateFormat dates = new SimpleDateFormat("mm/dd/yyyy");
//Setting dates
date1.setTime(System.currentTimeMillis());
CurrentDate = dates.format(date1);
date2 = dates.parse(FinalDate);
date1 = dates.parse(CurrentDate);
//Comparing dates
long difference = Math.abs(date1.getTime() - date2.getTime());
long differenceDates = difference/(24 * 60 * 60 * 1000);
//Convert long to String
dayDifference = Long.toString(differenceDates);
Log.e("HERE.................", "HERE: " + dayDifference);
System.out.println("..............difference date " + dayDifference);
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Intent targetIntent = new Intent(this, Mnst.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, targetIntent, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setAutoCancel(true);
builder.setTicker("Predictor");
builder.setContentTitle("Miisky Notification");
builder.setContentText(
"You have " + dayDifference + " days left. Click on notification to know more..");
builder.setSmallIcon(R.drawable.miilogo);
builder.setSound(soundUri);
builder.setContentIntent(pendingIntent);
builder.setOngoing(true);
//builder.setSubText("Your vault number is " + s.vault_no); //API level 16
builder.setNumber(100);
builder.build();
//noinspection deprecation
myNotication = builder.getNotification();
builder.setAutoCancel(true);
manager.notify(11, myNotication);
Toast.makeText(getApplicationContext(), " " + dayDifference + " Days Left ",
Toast.LENGTH_LONG).show();
} catch (Exception exception) {
Log.e("DIDN'T WORK............", "exception " + exception);
}
}
}
這裏輸入的日期是「2016年8月24日」和當前日期是「2016年9月28日」。我得到4結果是不正確的。我認爲我必須使用日曆或東西,但沒有得到確切的方式來做那個..
看到這個鏈接http://stackoverflow.com/questions/21285161/android-difference-between-two-dates –
我使用這種格式mm/dd/yyyy ..並且我沒有使用hh:mm:ss ..但是在那個鏈接中,它計算基於小時數的天..我沒有使用hh:mm:ss。 –
