android获取系统当前年月日时分秒的时间

packageitokit.com;importandroid.app.Activity;importandroid.os.Bundle;importandroid.text.format.Time;importandroid.widget.TextView;publicclassShowTimeextendsActivity{/**Calledwhentheactivityisfirstcreated.*/@OverridepublicvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.main);TextViewmyTextView=(TextView)findViewById(R.id.myTextView);Timetime=newTime("GMT+8");time.setToNow();intyear=time.year;intmonth=time.month;intday=time.monthDay;intminute=time.minute;inthour=time.hour;intsec=time.second;myTextView.setText("当前时间为："+year+"年"+month+"月"+day+"日"+hour+"时"+minute+"分"+sec+"秒");}}

唯一不足是取出时间只有24小时模式.

========================================================================================

long time=System.currentTimeMillis();
final Calendar mCalendar=Calendar.getInstance();
mCalendar.setTimeInMillis(time);
取得小时：mHour=mCalendar.get(Calendar.HOUR);
取得分钟：mMinuts=mCalendar.get(Calendar.MINUTE);

如何获取Android系统时间是24小时制还是12小时制
ContentResolver cv = this.getContentResolver();
String strTimeFormat = android.provider.Settings.System.getString(cv,
android.provider.Settings.System.TIME_12_24);

if(strTimeFormat.equals("24"))

{
Log.i("activity","24");
}

Calendar c = Calendar.getInstance();
取得系统日期:year = c.get(Calendar.YEAR)
month = c.grt(Calendar.MONTH)
day = c.get(Calendar.DAY_OF_MONTH)
取得系统时间：hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE)

利用Calendar获取
Calendar c = Calendar.getInstance();
取得系统日期:year = c.get(Calendar.YEAR)
month = c.grt(Calendar.MONTH)
day = c.get(Calendar.DAY_OF_MONTH)
取得系统时间：hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE)
Calendar c = Calendar.getInstance();
取得系统日期:year = c.get(Calendar.YEAR)
month = c.grt(Calendar.MONTH)
day = c.get(Calendar.DAY_OF_MONTH)
取得系统时间：hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE)
