我希望在每分钟完成后显示一个Toast消息.我正在使用倒计时器并在文本视图中显示计时器.请帮我解决这个问题.以下是我的代码.

    @OverrIDeprotected 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;  }}

解决方法:

好的,你需要稍微改变你的代码,

>您需要将Seconds变量更改为类级别
>您需要更改您的间隔,如下所示,

来自counter = new MyCount(3600000,10); to counter = new MyCount(3600000,1000);因为第二个参数是毫秒.我在下面的代码中完成了所有更改,

public class MainActivity extends Activity{TextVIEw timerVIEw;button end,SOS;String output;MyCount counter;int length;// Change by Luciferlong seconds;@OverrIDeprotected 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() {}}@OverrIDepublic voID onDestroy(){    super.onDestroy();    counter.cancel();}}
