Android获取当前时间戳（四种方法）

//获取时间戳

long timecurrentTimeMillis = System.currentTimeMillis();

long timeGetTime =new Date().getTime();

long timeSeconds = System.currentTimeMillis();

long timeMillis = Calendar.getInstance().getTimeInMillis();

Log.d("test", "  当前时间戳1->:"+timecurrentTimeMillis);

Log.d("test", "  当前时间戳2->:"+timeGetTime);

Log.d("test", "  当前时间戳3->:"+timeSeconds);

Log.d("test", "  当前时间戳4->:"+timeMillis);

---

//转为yyyy年MM月dd日

SimpleDateFormat sdf =new SimpleDateFormat("yyyy年MM月dd日",Locale.getDefault());

String time1 = sdf.format(timecurrentTimeMillis);

String time2 = sdf.format(timeGetTime);

String time3 = sdf.format(timeSeconds);

String time4 = sdf.format(timeMillis);

Log.d("test", timecurrentTimeMillis +"  现在的时间1->:" + time1);

Log.d("test", timeGetTime +"  现在的时间2-->:" + time2);

Log.d("test", timeSeconds +"  现在的时间2-->:" + time3);

Log.d("test", timeMillis +"  现在的时间2-->:" + time4);

---

//转为yyyy年MM月dd日HH时mm分ss秒E

SimpleDateFormat sdfTwo =new SimpleDateFormat("yyyy年MM月dd日HH时mm分ss秒E",Locale.getDefault());

String time11 = sdfTwo.format(timecurrentTimeMillis);

String time22 = sdfTwo.format(timeGetTime);

String time33 = sdfTwo.format(timeSeconds);

String time44 = sdfTwo.format(timeMillis);

Log.d("test", timecurrentTimeMillis +"  现在的时间11->:" + time11);

Log.d("test", timeGetTime +"  现在的时间22-->:" + time22);

Log.d("test", timeSeconds +"  现在的时间33-->:" + time33);

Log.d("test", timeMillis +"  现在的时间44-->:" + time44);
