跟踪倒数计时器每分钟 [英] Track each minute in countdown timer
本文介绍了跟踪倒数计时器每分钟的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想告诉每个minute.I完成现在用的倒数计时器后祝酒消息，并显示定时器在文本view.Please帮我把这个problem.Following理清我的code
@覆盖
保护无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.track_me_mode）;
计数器=新mycount的（长度，10）;
counter.start（）;
}
}）;
公共类mycount的扩展CountDownTimer {
语境mContext;
公共mycount的（长millisInFuture，长countDownInterval）{
超（millisInFuture，countDownInterval）;
}
公共无效onTick（长millisUntilFinished）{
timerView.setText（formatTime（millisUntilFinished））;
}
公共无效onFinish（）{
}
}
公共字符串formatTime（long millis）来{
输出=;
长秒=米利斯/ 1000;
长分=秒/ 60;
长时间=分钟/ 60;
秒=秒％60;
分钟=分钟％60;
小时=小时％60;
字符串secondsD =将String.valueOf（秒）;
字符串minutesD =将String.valueOf（分钟）;
字符串hoursD =将String.valueOf（小时）;
的System.out.println（minutesD）;
如果（秒-1，10）
secondsD =0+秒;
如果（分钟小于10）
minutesD =0+分钟;
如果（小时小于10）
hoursD =0+小时;
输出= hoursD +：+ minutesD +：+ secondsD;
返回输出;
}
}
解决方案
好了，您需要更改code点点，
- 您需要更改秒变量一流水平
-
您需要更改区间如下，
从
计数器=新mycount的（3600000,10）;到计数器=新mycount的（3600000,1000）;，因为第二个参数是毫秒。我已经做了所有的变化，跌破code，公共类MainActivity扩展活动 { TextView的timerView; 按钮结束，SOS; 字符串输出; mycount的计数器; INT长; //路西法更改 长秒; @覆盖 保护无效的onCreate（包savedInstanceState） { super.onCreate（savedInstanceState）; 的setContentView（R.layout.activity_main）; timerView =（TextView中）findViewById（R.id.tv_timer_track_me）; //计数器=新mycount的（3600000,10）; 计数器=新mycount的（3600000,1000）; counter.start（）; } 公共字符串formatTime（long millis）来 { 输出=; 秒=米利斯/ 1000; 长分=秒/ 60; 长时间=分钟/ 60; 秒=秒％60; 分钟=分钟％60; 小时=小时％60; 字符串secondsD =将String.valueOf（秒）; 字符串minutesD =将String.valueOf（分钟）; 字符串hoursD =将String.valueOf（小时）; 如果（秒-1，10） secondsD =0+秒; 如果（分钟小于10） minutesD =0+分钟; 如果（小时小于10） hoursD =0+小时; 输出= hoursD +：+ minutesD +：+ secondsD; 返回输出; } 公共类mycount的扩展CountDownTimer { 语境mContext; 公共mycount的（长millisInFuture，长countDownInterval） { 超（millisInFuture，countDownInterval）; } 公共无效onTick（长millisUntilFinished） { timerView.setText（formatTime（millisUntilFinished））; 如果（秒== 0） { Toast.makeText（getApplicationContext（），完成，Toast.LENGTH_LONG）.show（）; } } 公共无效onFinish（）{} } @覆盖 公共无效的onDestroy（） { super.onDestroy（）; counter.cancel（）; } }
I want to show a toast message after completion of each minute.I am using the count down timer and show the timer in a text view.Please help me to sort out this problem.Following is my code.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.track_me_mode);
counter = new MyCount (length,10);
counter.start();
}
});
public class MyCount extends CountDownTimer {
Context mContext;
public MyCount(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
public void onTick (long millisUntilFinished) {
timerView.setText ( formatTime(millisUntilFinished));
}
public void onFinish() {
}
}
public String formatTime(long millis) {
output = "";
long seconds = millis / 1000;
long minutes = seconds / 60;
long hours=minutes/ 60;
seconds = seconds % 60;
minutes = minutes % 60;
hours=hours%60;
String secondsD = String.valueOf(seconds);
String minutesD = String.valueOf(minutes);
String hoursD=String.valueOf(hours);
System.out.println(minutesD);
if (seconds < 10)
secondsD = "0" + seconds;
if (minutes < 10)
minutesD = "0" + minutes;
if (hours < 10)
hoursD = "0" + hours;
output = hoursD+" : "+minutesD + " : " + secondsD;
return output;
}
}
解决方案
Ok, You need to change your code little bit,
- You need to change your Seconds variable to class level
You need to change your interval as follows,
from
counter = new MyCount (3600000,10);tocounter = new MyCount (3600000,1000);because second argument is millisecond. I have done all the changes in below code,public class MainActivity extends Activity { TextView timerView; Button end,SOS; String output; MyCount counter; int length; // Change by Lucifer long seconds; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); timerView=(TextView)findViewById(R.id.tv_timer_track_me); // counter = new MyCount (3600000,10); counter = new MyCount (3600000,1000); counter.start(); } public String formatTime(long millis) { output = ""; seconds = millis / 1000; long minutes = seconds / 60; long hours=minutes/ 60; seconds = seconds % 60; minutes = minutes % 60; hours=hours%60; String secondsD = String.valueOf(seconds); String minutesD = String.valueOf(minutes); String hoursD=String.valueOf(hours); if (seconds < 10) secondsD = "0" + seconds; if (minutes < 10) minutesD = "0" + minutes; if (hours < 10) hoursD = "0" + hours; output = hoursD+" : "+minutesD + " : " + secondsD; return output; } public class MyCount extends CountDownTimer { Context mContext; public MyCount(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); } public void onTick (long millisUntilFinished) { timerView.setText ( formatTime(millisUntilFinished)); if ( seconds == 0 ) { Toast.makeText( getApplicationContext(), "Done", Toast.LENGTH_LONG ).show(); } } public void onFinish() {} } @Override public void onDestroy() { super.onDestroy(); counter.cancel(); } }
