Una forma agradable y sencilla de crear una pausa / reanudar para su CountDownTimer es crear un método separado para su temporizador comienzo, pausa y reanudar como sigue:
public void timerStart(long timeLengthMilli) {
timer = new CountDownTimer(timeLengthMilli, 1000)
@Override
public void onTick(long milliTillFinish)
milliLeft=milliTillFinish;
min = (milliTillFinish/(1000*60));
sec = ((milliTillFinish/1000)-min*60);
clock.setText(Long.toString(min)+":"+Long.toString(sec));
Log.i("Tick", "Tock");
timer.start();
El timerStart tiene un parámetro largo ya que será reutilizado por el reanudar() método a continuación. Recuerde almacenar su milliTillFinished (arriba como miliLeft) para que pueda enviarlo en su reanudar() método. Pausar y reanudar los métodos siguientes, respectivamente:
public void timerPause()
timer.cancel();
private void timerResume()
Log.i("min", Long.toString(min));
Log.i("Sec", Long.toString(sec));
timerStart(milliLeft);
Aquí está el código para el botón FYI:
startPause.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(startPause.getText().equals("Start"))
Log.i("Started", startPause.getText().toString());
startPause.setText("Pause");
timerStart(15*1000);
else if (startPause.getText().equals("Pause"))
Log.i("Paused", startPause.getText().toString());
startPause.setText("Resume");
timerPause();
else if (startPause.getText().equals("Resume"))
startPause.setText("Pause");
timerResume();
Bueno, no hay API para pausarlo o reanudarlo. Lo que debes hacer es cancel() el temporizador y almacenar el tiempo restante en una variable. Cuando vuelva a presionar el botón de reanudar, reinicie el temporizador con el valor de la variable.
Sabe que los cronómetros pueden ser de su interés.
