天文台重置
我正在尝试完全重新启动 Chronometer,但它不起作用。相反,它正在暂停。基本上我想做的是在计时器计数到 10 时做一些事情。完成后我们提示用户重试。在这种情况下,我们希望从 1 秒重新计数到 10 秒。但是计时器从暂停时间开始,而不是从 0 开始。
代码如下:
_cutOfTime = 10; // constant
每次按下按钮时,startRecording()
都应该启动计时器,而不是停止/暂停它,但确实如此相反
protected void startRecording(){
this._watch = (Chronometer) findViewById(R.id.chrono);
if (this._watch != null)
this._watch.setOnChronometerTickListener(new OnChronometerTickListener() {
@Override
public void onChronometerTick(Chronometer chronometer) {
long countUp = (SystemClock.elapsedRealtime() - chronometer.getBase()) / 1000;
Log.i(_tag, "time now: " + String.valueOf(countUp));
if(countUp > _cutOfTime)
{
Log.i(_tag, "stop recording!!: ");
_watch.stop();
stopRecordWav();
launchPromptWithResults();
}
long sec = countUp % 60;
String asText = "" + sec;
_textView.setText("Recorded: " + asText);
}
});
if (_watch != null)
_watch.start();
}
有没有办法重置计时器,使其不暂停而是完全停止?
I am trying to completely restart Chronometer and its does not work. Instead it is being paused. Basically what I am trying to do is to do something while chronometer is counting till 10. After its done we prompt the user to try again. In which case we want to redo the count from 1 to 10 sec. But the Chronometer starts from the paused time instead of starting 0.
here is the code:
_cutOfTime = 10; // constant
every time button is pressed do startRecording()
it should always initiate the Chronometer instead of stop/pause it, but it does the opposite
protected void startRecording(){
this._watch = (Chronometer) findViewById(R.id.chrono);
if (this._watch != null)
this._watch.setOnChronometerTickListener(new OnChronometerTickListener() {
@Override
public void onChronometerTick(Chronometer chronometer) {
long countUp = (SystemClock.elapsedRealtime() - chronometer.getBase()) / 1000;
Log.i(_tag, "time now: " + String.valueOf(countUp));
if(countUp > _cutOfTime)
{
Log.i(_tag, "stop recording!!: ");
_watch.stop();
stopRecordWav();
launchPromptWithResults();
}
long sec = countUp % 60;
String asText = "" + sec;
_textView.setText("Recorded: " + asText);
}
});
if (_watch != null)
_watch.start();
}
Is there a way to reset the chronometer so it does not pause but completely stop?

当我不久前使用计时器时,我只是在调用 start() 之前使用 setBase() 方法将基准设置为当前时间。根据您的具体需求,您可能需要在启动之前添加一些关于是否重置计时器的逻辑。
When I played with the chronometer awhile back I just used the setBase() method to set the base to the current time just before calling start(). Depending on your exact needs you may need to add some logic around whether to reset the chronometer or not before starting it.
