一个获取当前时间的类:
1 import android.annotation.SuppressLint; 2 import android.os.Handler; 3 import android.os.Message; 4 import android.util.Log; 5 import android.widget.TextView; 6 7 import com.acmeinte.idl.sample.common.Constants; 8 import com.acmeinte.idl.sample.common.EventMsg; 9 import com.acmeinte.idl.sample.manager.DBFileManager; 10 import com.acmeinte.idl.sample.manager.DataMessage; 11 12 import org.greenrobot.eventbus.EventBus; 13 14 import java.text.SimpleDateFormat; 15 import java.util.Calendar; 16 import java.util.Date; 17 import java.util.TimeZone; 18 19 //*** 20 //更新时间类 21 //*** 22 public class ThreadTime extends Thread { 23 public TextView tvDate; 24 private int msgKey1 = 22; 25 26 public ThreadTime(TextView tvDate) { 27 this.tvDate = tvDate; 28 } 29 30 @Override 31 public void run() { 32 do { 33 try { 34 Thread.sleep(1000); 35 Message msg = new Message(); 36 msg.what = msgKey1; 37 mHandler.sendMessage(msg); 38 } catch (InterruptedException e) { 39 e.printStackTrace(); 40 } 41 } while (true); 42 } 43 44 45 @SuppressLint("HandlerLeak") 46 private Handler mHandler = new Handler() { 47 @SuppressLint("SetTextI18n") 48 @Override 49 public void handleMessage(Message msg) { 50 super.handleMessage(msg); 51 switch (msg.what) { 52 case 22: 53 SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss"); 54 String date = sdf.format(new Date()); 55 tvDate.setText(deviceTime() + date + " " + getWeek()); 56 65 break; 66 default: 67 break; 68 } 69 } 70 }; 71 72 /** 73 * 获取今天星期几 74 * 75 * @return 76 */ 77 public static String deviceTime() { 78 Calendar calendar = Calendar.getInstance(); 79 calendar.setTimeZone(TimeZone.getTimeZone("GMT+8:00")); 80 String year; 81 String month; 82 String day; 83 String deviceTime; 84 85 year = String.valueOf(calendar.get(Calendar.YEAR)); 86 month = String.valueOf(calendar.get(Calendar.MONTH) + 1); 87 day = String.valueOf(calendar.get(Calendar.DATE)); 88 deviceTime = year + "-" + month + "-" + day + " "; 89 90 return deviceTime; 91 } 92 93 /** 94 * 获取今天星期几 95 * 96 * @return 97 */ 98 public static String getWeek() { 99 Calendar calendar = Calendar.getInstance(); 100 int i = calendar.get(Calendar.DAY_OF_WEEK); 101 switch (i) { 102 case 1: 103 return "周日"; 104 case 2: 105 return "周一"; 106 case 3: 107 return "周二"; 108 case 4: 109 return "周三"; 110 case 5: 111 return "周四"; 112 case 6: 113 return "周五"; 114 case 7: 115 return "周六"; 116 default: 117 return ""; 118 } 119 } 120 121 131 }
然后再UI界面修改txt参数实现时间显示:
1 //时间
2
3 TextView time_device ;
4 time_device = findViewById(R.id.txt_time_device);
5 ThreadTime threadTime = new ThreadTime(time_device);
6 threadTime.start();
