I have a countdown timer, I have a button that pause it, but I need that when you click on button, continue to countdown. I search but couldn't a function related this. How can do it? This is my code, I only managed to restart it, but not continue:
private TextView cuentaRegresiva;
private Button btnEmpezar;
private CountDownTimer countDownTimer;
private boolean timerHasStarted = false;
private long startTime = 30 * 1000;
private final long interval = 1 * 1000;
private long restante;
@Override
protected void onCreate(Bundle savedInstanceState) {
...
btnEmpezar.setOnClickListener(iniciar);
}
OnClickListener iniciar=new OnClickListener() {
@Override
public void onClick(View arg0) {
if (!timerHasStarted && !pausado) {
countDownTimer.start();
timerHasStarted = true;
btnEmpezar.setText("Pause");
pausado=false;
}
else if(timerHasStarted && !pausado){
countDownTimer.cancel();
timerHasStarted = false;
btnEmpezar.setText("Restart");
pausado=true;
}
else if(!timerHasStarted && pausado){
countDownTimer2.start();
timerHasStarted = true;
btnEmpezar.setText("Pause");
pausado=false;
}
}
};
public class MyCountDownTimer extends CountDownTimer {
public MyCountDownTimer(long startTime, long interval) {
super(startTime, interval);
}
@Override
public void onFinish() {
cuentaRegresiva.setText("Tiempo!");
}
@Override
public void onTick(long millisUntilFinished) {
cuentaRegresiva.setText("" + millisUntilFinished / 1000);
}
}
public class MyCountDownTimer2 extends CountDownTimer {
public MyCountDownTimer2(long restante, long interval) {
super(restante, interval);
}
@Override
public void onFinish() {
cuentaRegresiva.setText("Tiempo!");
}
@Override
public void onTick(long millisUntilFinished) {
cuentaRegresiva.setText("" + millisUntilFinished / 1000);
}
}
I thought about taking millisUntilFinished to a variable, but didn't work. Anyway I guess the way is close to that.
You can try saving the seconds until finish, and then you can start the new countdown timer with that seconds.
// -----------------------
Cuando presionas el boton de pausa, guarda los segundos que le faltan al timer para que termine. Entonces, cuando volves a apretar play, creas un nuevo CountDownTimer con esos segundos que te faltaban.
UPDATE
I did an example:
public class MainActivity extends Activity {
private static final int TIMER_TIME = 10000; // in millis
private Button btnCountdown;
private TextView tvTimeUntilFinish;
private boolean mIsPaused = true;
private long mMillisUntilFinish;
private CountDownTimer mTimer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMillisUntilFinish = TIMER_TIME;
btnCountdown = (Button) findViewById(R.id.btnCountdown);
tvTimeUntilFinish = (TextView) findViewById(R.id.tvTimeUntilFinish);
btnCountdown.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
if (mIsPaused) {
btnCountdown.setText("Pause");
initTimer();
} else {
btnCountdown.setText("Play");
cancelTimer();
}
mIsPaused = !mIsPaused;
}
});
}
private void cancelTimer() {
if (mTimer != null) {
mTimer.cancel();
mTimer = null;
}
}
private void initTimer() {
mTimer = new CountDownTimer(mMillisUntilFinish, 1000) {
public void onTick(long millisUntilFinished) {
tvTimeUntilFinish.setText("seconds remaining: " + millisUntilFinished / 1000);
mMillisUntilFinish = millisUntilFinished;
}
public void onFinish() {
}
}.start();
}
}
