how to convert a date dd / mm / yyyy to yyyy-MM-dd HH:mm:ss Android
提问by Douglas Mesquita
How can I convert a date in dd / mm / yyyy to a format that supports sqlite yyyy-MM-dd'T'HH: mm: ss
如何将 dd / mm / yyyy 中的日期转换为支持 sqlite yyyy-MM-dd'T'HH: mm: ss 的格式
for example:
例如：
public static String convertStringToData(String stringData)
throws ParseException {
SimpleDateFormat sdf = new SimpleDateFormat("dd/mm/aaaa");//yyyy-MM-dd'T'HH:mm:ss
SimpleDateFormat output = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date data = sdf.parse(stringData);
String formattedTime = output.format(data);
return formattedTime;
}

public static String formatDate (String date, String initDateFormat, String endDateFormat) throws ParseException {
Date initDate = new SimpleDateFormat(initDateFormat).parse(date);
SimpleDateFormat formatter = new SimpleDateFormat(endDateFormat);
String parsedDate = formatter.format(initDate);
return parsedDate;
}
This will return the parsed date as a String, with the format (both initial and end) as parameters to the method.
这会将解析后的日期作为字符串返回，格式（初始和结束）作为方法的参数。

SimpleDateFormat originalFormat = new SimpleDateFormat("dd MM yyyy");
SimpleDateFormat targetFormat = new SimpleDateFormat("yyyy MM dd HH:mm:ss" );
Date date;
try {
date = originalFormat.parse("21 6 2013");
System.out.println("Old Format : " + originalFormat.format(date));
System.out.println("New Format : " + targetFormat.format(date));
} catch (ParseException ex) {
// Handle Exception.
}
Old Format : 21 06 2013
旧格式：21 06 2013
New Format : 2013 06 21 00:00:00
新格式：2013 06 21 00:00:00

Date initDate = new SimpleDateFormat("dd/MM/yyyy").parse("10/12/2016");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String parsedDate = formatter.format(initDate);
System.out.println(parsedDate);

public static final String DATE_DASH_FORMAT = "yyyy-MM-dd";
public static final String DATE_FORMAT = "MM/dd/yyyy";
public static String prepareYearMonthDateFromString( String dateStr ){
try
{
Date date = new SimpleDateFormat( DATE_FORMAT , Locale.ENGLISH ).parse( dateStr );
DateFormat formatter = new SimpleDateFormat( DATE_DASH_FORMAT , Locale.getDefault() );
dateStr = formatter.format( date.getTime() );
}
catch( ParseException e )
{
e.printStackTrace();
}
return dateStr;
}
