我做了一个计时器，如果按秒，100毫秒为单位计时，则时间显示的很流畅。
如果改为10毫秒为单位，在模拟器上显示也很流畅，但安装到手机里后反应就缓慢了，有延迟，时间每次不是0.01秒的显示，而是中间有很大间隔
如果改为1毫秒为单位，在模拟器上显示都不流畅了，在手机上更不行了。
该怎么解决呢？
我的实现方法为：
1.设置计时器，时间间隔mlTimerUnit根据用户的设置设置不同的值
按秒计时，则为1000
按100毫秒计时，则为100
按10毫秒计时，则为10
按1毫秒计时，则为1
- Java code
if (null == timer) { if (null == task) { task = new TimerTask() { @Override public void run() { // TODO Auto-generated method stub if (null == msg) { msg = new Message(); } else { msg = Message.obtain(); } msg.what = 1; handler.sendMessage(msg); } }; } timer = new Timer(true); timer.schedule(task, mlTimerUnit, mlTimerUnit); // set timer duration }2.显示计时时间的方法
- Java code
// Handle timer message handler = new Handler(){ @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub switch(msg.what) { case 1: mlCount++; int totalSec = 0; int yushu = 0; if (SETTING_SECOND_ID == settingTimerUnitFlg) { // second totalSec = (int)(mlCount); } else if (SETTING_100MILLISECOND_ID == settingTimerUnitFlg) { // 100 millisecond totalSec = (int)(mlCount / 10); yushu = (int)(mlCount % 10); } else if (SETTING_10MILLISECOND_ID == settingTimerUnitFlg) { // 10 millisecond totalSec = (int)(mlCount / 100); yushu = (int)(mlCount % 100); } else if (SETTING_MILLISECOND_ID == settingTimerUnitFlg) { // 1 millisecond totalSec = (int)(mlCount / 1000); yushu = (int)(mlCount % 1000); } // Set time display int min = (int)(totalSec / 60); int sec = (int)(totalSec % 60); try{ if (SETTING_SECOND_ID == settingTimerUnitFlg) { // second(1000ms) tvTime.setText(String.format("%1$02d:%2$02d", min, sec)); } else if (SETTING_100MILLISECOND_ID == settingTimerUnitFlg) { // 100 millisecond tvTime.setText(String.format("%1$02d:%2$02d:%3$d", min, sec, yushu)); } else if (SETTING_10MILLISECOND_ID == settingTimerUnitFlg) { // 10 millisecond tvTime.setText(String.format("%1$02d:%2$02d:%3$02d", min, sec, yushu)); } else if (SETTING_MILLISECOND_ID == settingTimerUnitFlg) { // 1 millisecond tvTime.setText(String.format("%1$02d:%2$02d:%3$03d", min, sec, yushu)); } } catch(Exception e) { tvTime.setText("" + min + ":" + sec + ":" + yushu); e.printStackTrace(); Log.e("MyTimer onCreate", "Format string error."); } break; default: break; } super.handleMessage(msg); } };
