1、文件大小格式化:
Log.d(TAG, Formatter.formatFileSize(this, 100));
//100 B
Log.d(TAG, Formatter.formatFileSize(this, 1024*2));
//2.00 KB
Log.d(TAG, Formatter.formatFileSize(this, 10000000));
//9.54 MB
2、日期格式化:
int flagsDate = DateUtils.FORMAT_SHOW_DATE;
int flagsTime = DateUtils.FORMAT_SHOW_TIME ;
int flagsWeek = DateUtils.FORMAT_SHOW_WEEKDAY;
int flags_time = DateUtils.FORMAT_SHOW_TIME | DateUtils.FORMAT_24HOUR;
String dateStr = (String)DateUtils.formatDateTime(this, System.currentTimeMillis(), flagsDate);
//7月8日
String timeStr = (String)DateUtils.formatDateTime(this, System.currentTimeMillis(), flagsTime);
//下午1:33
String weekStr = (String)DateUtils.formatDateTime(this, System.currentTimeMillis(), flagsWeek);
//星期二
String amPmStr = DateUtils.getAMPMString(Calendar.getInstance().get(Calendar.AM_PM));
//下午
String datetime = DateFormat.format("yyyy:MM:dd kk:mm:ss", System.currentTimeMillis()).toString();
//2014:07:08 13:33:23
String time = (String)DateUtils.formatDateTime(this, System.currentTimeMillis(), flags_time);
//13:33
boolean isToday = DateUtils.isToday(System.currentTimeMillis());
//true
