android获取系统当前年月日时分秒的时间

package itokit.com;   
  
import android.app.Activity;   
import android.os.Bundle;   
import android.text.format.Time;   
import android.widget.TextView;   
  
public class ShowTime extends Activity {   
    /** Called when the activity is first created. */  
    @Override  
    public void onCreate(Bundle savedInstanceState) {   
        super.onCreate(savedInstanceState);   
        setContentView(R.layout.main);   
           
        TextView myTextView = (TextView)findViewById(R.id.myTextView);   
        Time time = new Time("GMT+8");    
        time.setToNow();   
        int year = time.year;   
        int month = time.month;   
        int day = time.monthDay;   
        int minute = time.minute;   
        int hour = time.hour;   
        int sec = 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)
