  // 获取当前日期，设置日期编辑框默认显示当前日期
Calendar cal = Calendar.getInstance();
year = cal.get(Calendar.YEAR);
month = cal.get(Calendar.MONTH) + 1;
day = cal.get(Calendar.DAY_OF_MONTH);
dateEdit.setText(year + "-" + month + "-" + day);
SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

Log.i("zy", "-dateFormat.format(date)--------"+dateFormat.format(date));
Log.i("zy", "dateFormat.format(时间戳)------------"+dateFormat.format(java.lang.System.currentTimeMillis()));
