beim Lesen von Kalenderereignissen, wie Datum in Datum Monat Jahr zu trennen und in drei Variablen zu speichern

Question

Dies ist mein Code und ich versuche, Kalenderereignisse zu lesen und nur das Datum, Monat und Jahr des Ereignisses in drei separate Variablen zu erhalten .

public void read_calendar(){ 
    ContentResolver cr = getContentResolver(); 
    Cursor cursor = cr.query(Uri.parse("content://com.android.calendar/events"), new String[]{ "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }, null, null, null); 
    //Cursor cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "name" }, null, null, null); 
    String add = null; 
    cursor.moveToFirst(); 
    String[] CalNames = new String[cursor.getCount()]; 
    int[] CalIds = new int[cursor.getCount()]; 
    for (int i = 0; i < CalNames.length; i++) { 
     CalIds[i] = cursor.getInt(0); 
     CalNames[i] = ""+new Date(cursor.getLong(3))+"\n"+ cursor.getString(1); 
     if(add == null) 
      add = CalNames[i]; 
     else{ 
      add += CalNames[i]; 
     } 
     textView3.setVisibility(View.VISIBLE); 
     textView3.setText(add); 

     cursor.moveToNext(); 
    } 
    cursor.close(); 
} 

Answer 1

Dies, wie Sie in der Lage können Datum Monat und Jahr nach Split.

 CalNames[i] = "" + new Date(cursor.getLong(3)); 
       DateFormat sdf; 

       try { 


        // Tue Jan 27 00:00:00 GMT+05:30 2016 
        sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH); 
        Date date = sdf.parse(CalNames[i]); 
        //sdf = new SimpleDateFormat("EEEE MMM yyy", Locale.ENGLISH); 
sdf = new SimpleDateFormat("dd MM yyyy", Locale.ENGLISH); 
        CalNames[i] = sdf.format(date); 
        String[] datesArray = CalNames[i].split(" "); 
        String _date = datesArray[0]; 
        String _month = datesArray[1]; 
        String _year = datesArray[2]; 
    //    Log.e("DATE S:", ":" + CalNames[i]); 
        Log.d("DATE S:", _date + "\n" + _month + "\n" + _year); 

       } catch (ParseException e) { 
        e.printStackTrace(); 
       }

// I have Formatted the date object as per requirement. 
// eg 26-09-2016 
public void read_calendar(){ 
    ContentResolver cr = getContentResolver(); 
    Cursor cursor = cr.query(Uri.parse("content://com.android.calendar/events"), new String[]{ "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }, null, null, null); 
    //Cursor cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "name" }, null, null, null); 
    String add = null; 
    cursor.moveToFirst(); 
    String[] CalNames = new String[cursor.getCount()]; 
    int[] CalIds = new int[cursor.getCount()]; 
    for (int i = 0; i < CalNames.length; i++) { 
     CalIds[i] = cursor.getInt(0); 
     Date dateObj = new Date(cursor.getLong(3)); 
     String sdfCalDate = new SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH).format(dateObj); 

     CalNames[i] = ""+ sdfCalDate+"\n"+ cursor.getString(1); 
     if(add == null) 
      add = CalNames[i]; 
     else{ 
      add += "\n \n"+CalNames[i]; 
     } 
     textView3.setVisibility(View.VISIBLE); 
     textView3.setText(add); 

     cursor.moveToNext(); 
    } 
    cursor.close(); 
}
