我在以色列擔任足球(足球)裁判員,我被要求編寫一個應用程序來模擬即將到來的賽季的健身測試。 該測試是一個間隔測試,用戶可以輸入他跑了多少次,走多少次以及多少次。 每次啓動/停止運行時都會發出蜂鳴聲(beep
變量的類型爲MediaPlayer
)。每次完成跑步/行走時,計時錶應該重置。android天文臺時間間隔和重置
下面的代碼幾乎工程 - 嗶聽到聲音在正確的時間和集數權後停止,但畫面卡住的計時錶開始之後...
我會很感激你善意的幫助! 謝謝,Yaad
private void testLoop() {
int i = 0;
boolean flag = true; //true = running, false = walking
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.start();
//run, walk, rep = integers that are set by user input
beep.start();
tvRunWalk.setText("Running");
tvRepNum.setText(String.format("Repetition Number: %d", i + 1));
while (i < rep) //rep = number of repetitions
{
if (SystemClock.elapsedRealtime() - chronometer.getBase() == run * 1000 && flag) //if running time is over and you are now running
{
chronometer.setBase(SystemClock.elapsedRealtime());
flag = false;
tvRunWalk.setText("Walking");
beep.start();
}
else if (SystemClock.elapsedRealtime() - chronometer.getBase() == walk * 1000 && !flag) //if walking time is over and you are now walking
{
chronometer.setBase(SystemClock.elapsedRealtime());
flag = true;
i++;
tvRunWalk.setText("Running");
tvRepNum.setText(String.format("Repetition Number: %d", i + 1));
beep.start();
}
}
