关于安卓开始实现最简单地获取系统时间

 1 package lianxi;

 2 

 3 import com.example.jichu_lianxi.R;

 4 

 5 import android.app.Activity; 

 6 

 7 import android.os.Bundle; 

 8 

 9 import android.text.format.Time; 

10 

11 import android.widget.TextView; 

12 import android.widget.Toast;

13 

14 public class GetTime extends Activity { 

15 

16 /** Called when the activity is first created. */ 

17 

18 @Override 

19 

20 public void onCreate(Bundle savedInstanceState) { 

21 

22 super.onCreate(savedInstanceState); 

23 

24 setContentView(R.layout.gettime); 

25 

26 TextView myTextView = (TextView)findViewById(R.id.getTime); 

27 Time time = new Time("GMT+8"); 

28 time.setToNow(); 

29 int year = time.year;           //获取年份

30 int month = time.month;         //获取月份

31 int day = time.monthDay;        //获取日号

32 int hour = time.hour;           //获取小时，注意，这里的小时是24制的

33 int minute = time.minute;       //获取分钟

34 int sec = time.second;          //获取秒

35 String time_s = "当前时间为：" + year + "年 " + month + "月 " + day + "日 " + hour + "时 " + minute + "分 " + sec + "秒"; 

36 Toast.makeText(GetTime.this,time_s, Toast.LENGTH_SHORT).show();

37 

38 

39 } 

40 

41 } 

第二种方法：

package lianxi;



import com.example.jichu_lianxi.R;



import android.app.Activity; 



import android.os.Bundle; 



import android.text.format.Time; 



import android.widget.TextView; 

import android.widget.Toast;



public class GetTime extends Activity { 



/** Called when the activity is first created. */ 



@Override 



public void onCreate(Bundle savedInstanceState) { 



super.onCreate(savedInstanceState); 



setContentView(R.layout.gettime); 



 Calendar c = Calendar.getInstance();

                int year = c.get(Calendar.YEAR);   //获取年份 

                int month = c.get(Calendar.MONTH);  //获取月份

                int day = c.get(Calendar.DAY_OF_MONTH);  //获取日期

                int hour = c.get(Calendar.HOUR_OF_DAY);  //获取小时

                int minute = c.get(Calendar.MINUTE); //获取分钟
String time_s = "当前时间为：" + year + "年 " + month + "月 " + day + "日 " + hour + "时 " + minute + "分 ";
Toast.makeText(GetTime.this,time_s, Toast.LENGTH_SHORT).show();





} 



}
