I tried to build a contdown timer with pause button, for making timer to pause I tried to build a new timer with the left time, below is my code, but the problem is that it works just once, after pressing pause button for twice, old timer does not get cancel and wotks with the new one, what can I do?
pauseB.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (!timerHasPaused) {
startTime = (long) (temp * 1000);
countDownTimer.cancel();
countDownTimer = new MyCountDownTimer(startTime, interval);
timerHasPaused = true;
pauseB.setText("Play");
} else {
PcountDownTimer.start();
timerHasStarted = false;
pauseB.setText("Pause");
}
}
});

How can I pause the countdownTimer if a dialog need to appear first. What can I do so that the timer will not start until I click the ok button.
countDownTimer = new CountDownTimer(320000, 1200) {
#Override
public void onTick(long l) {
timeText.setText(String.valueOf(timeValue));
timeValue = timeValue - 1;
if (timeValue == -1){
FLAG = 3;
playAudio.setAudioforEvent(FLAG);
timerDialog.timerDialog();
countDownTimer.cancel();
dbHandler.addScore2(tag,Integer.parseInt(txtCorrect.getText().toString()));
}
}
#Override
public void onFinish() {
// timerDialog.timerDialog();
}
}.start();
This is the dialog that will appear first.
public void fillDialog(){
fillDialog = new Dialog(mnContext);
fillDialog.setContentView(R.layout.activity_instruction_fill);
final Button btdialog = (Button) fillDialog.findViewById(R.id.ok_btn_fill);
btdialog.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
fillDialog.dismiss();
}
});
You can use the countdownTimer.cancel() method to pause the countdown timer. When the dialog appears, call this method to pause the timer. When the user clicks the "OK" button on the dialog, you can then call the countdownTimer.start() method to resume the timer from where it left off.
Alternatively, you can also use countdownTimer.pause() and countdownTimer.resume() to pause and resume the timer.
It would be good to keep in mind that countdownTimer is a android class and you need to call the above methods from your activity class
I am using following code for using a button. I works.(sendBtn is a button in a fragment)
sendText = view.findViewById(R.id.send_text);
View sendBtn = view.findViewById(R.id.send_btn);
sendBtn.setOnClickListener(v -> send(sendText.getText().toString()));
Now i want to disable the button for 1 sec after a click
I found following solution but above code works "without onClick(View v)"method and without implementing View.OnClickListener in class. How to provide delay in such case..How code is working without onClick method.
#Override
public void onClick(View v) {
((Button) findViewById(R.id.click)).setEnabled(false);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
((Button) findViewById(R.id.click))
.setEnabled(true);
}
}, 1000);
}
});
Use this method when you want to interrupt user clicks:
private static long mLastClickTime = 0L;
public static boolean isOpenRecently() {
if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) {
return true;
}
mLastClickTime = SystemClock.elapsedRealtime();
return false;
}
Usage:
if (v.getId() == R.id.sendBtn) {
if (isOpenRecently()) return;
// Your logic
}
Basically you are using lambda in your code, where v->{} represents the onCLick(View v) function.
sendBtn.setOnClickListener(v -> send(sendText.getText().toString()));
You can do the following to disable the button for 1 second
void doOnSendButtonClick(View v){
//Send the message (your logic here)
send(sendText.getText().toString());
//Disable button
sendBtn.setEnabled(false);
//enable button after 1000 millisecond
new Handler(Looper.getMainLooper()).postDelayed(() -> {
sendBtn.setEnabled(true);
}, 1000);
}
And call this method when user clicks on the button
sendButton.setOnClickListener(view -> doOnSendButtonClick(view));
You could use a CountDownTimer.
CountDownTimewr timer = new CountDownTimer(1000, 1000) {
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
// enable button
((Button) findViewById(R.id.click)).setEnabled(true);
}
}
#Override
public void onClick(View v) {
// disable btn and start timer of one second in millis
((Button) findViewById(R.id.click)).setEnabled(false);
timer.start();
}
});
Please try this way
Handler(Looper.getmainLooper()) and remove callback after you done your task inside runnable thread...also try to put this logic in any method outside in this class and call from setonclicklistener
Try the Timer.shedule with timertask
you can use runOnUIThread method inside where you can update UI.
you can also try to check the time difference of click and enable again in looping like while.
I am trying to create a countdown timer that will increases its speed after a button press I uses the counter also to adjust a progress bar.
Right now I am adjusting the speed (increasing) after the button is pressed but it does not start from the beginning. For example, when I start my program the timer start from the beginning and decreases progressively, which is fine. However, when I press the button the counter does not start from the beginning like this:
I want just to make it run faster after each button press, not to decrease the length.
this is my code:
mTrueBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//is the user right? if pressing True button
if(isMathProblemTrue == 1){
//user is correct
Toast.makeText(MainActivity.this,"Correct!",Toast.LENGTH_SHORT).show();
generateMathProblem();
timer_length *= 0.8;
timer_interval *= 0.8;
Log.d(TAG,"time length:"+timer_length);
Log.d(TAG,"time interval:"+timer_interval);
mCountDownTimer.cancel();
createNStartTimer();
//restartTimer();
}else{
//user is incorrect
transferUserToStartScreen();
//reset the timer
mCountDownTimer.cancel(); // cancel
}
}
});
private void createNStartTimer() {
mCountDownTimer = new CountDownTimer(timer_length,timer_interval) {
#Override
public void onTick(long millisUntilFinished) {
Log.d(TAG,"Mil until finish:"+millisUntilFinished);
int progress = (int) (millisUntilFinished/100);
mProgressBar.setProgress(progress);
}
#Override
public void onFinish() {
mProgressBar.setProgress(0);
transferUserToStartScreen();
}
}.start();
}
create 2 global constants outside the functions
int totalMillisUntilFinished = 0;
bool firstTime = true;
we initialize the totalMillisUntilFinished when onTick is called for the time, so update your your onTick function:
private void createNStartTimer() {
firstTime = true;
mCountDownTimer = new CountDownTimer(timer_length,timer_interval) {
#Override
public void onTick(long millisUntilFinished) {
if(firstTime){totalMillisUntilFinished = millisUntilFinished; firstTime = false;}
Log.d(TAG,"Mil until finish:"+millisUntilFinished);
int progress = (int) (millisUntilFinished*100/totalMillisUntilFinished);
mProgressBar.setProgress(progress);
}
Personally, I use Handlers and Runnables, which I would definitely suggest looking into instead.
So I have this "hack" to have a toast duration a little bit longer:
// Toast...
zanimivosti = new Toast(getApplicationContext());
zanimivosti.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
zanimivosti.setView(layout);
new CountDownTimer(4000, 1000) {
public void onTick(long millisUntilFinished) {
zanimivosti.show();
}
public void onFinish() {
zanimivosti.show();
}
}.start();
PROBLEM: When a user go to another intent, it can happen that the toast reaper again in new intent.
In my case CountDownTimer.cancel(); won't work
ALTERNATIVE:
In my toast I am displaying news every time the user lunch the app. I would also take in consideration a better solution whit a toast that when a user click on it disappear or when new intent is called also disappear.
Should I use a pop up dialog? Can I make it disappear when user clicks on it?
At the end I did it like this:
Toast zanimivosti;
int cas = 4000;
int perioda = 1000;
boolean boolean_toast = true;
CountDownTimer timer;
timer = new CountDownTimer(time, perioda) {
public void onTick(long millisUntilFinished) {
zanimivosti.show();
}
public void onFinish() {
if (boolean_toast == true) {
zanimivosti.show();
} else {
}
}
}.start();
And stoping the timer with stopping/cancelling all the possible things:
boolean_toast = false;
time = 0;
perioda = 0;
timer.cancel();
zanimivosti.cancel();
Okay, so I have a countdown timer, and my app requires the user to tap a button numerous times, however the timer starts ON that button tap. My problem is:
I have a 10 second countdown timer that starts at the press of the button, but instead of just continuing down to 0, it restarts at 10 everytime the user taps the button. How do I make it so when the user taps it the first time, it keeps counting down?
My code:
private Button tapBtn;
TextView cm;
tapBtn = (Button) findViewById(R.id.Tap);
cm = (TextView) findViewById(R.id.Timer);
final CountDownTimer aCounter = new CountDownTimer(10000, 1000) {
public void onTick(long millisUntilFinished) {
cm.setText("Time Left: " + millisUntilFinished / 1000);
}
public void onFinish() {
cm.setText("Time's Up!");
}
};
aCounter.cancel();
tapBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
scr = scr - 1;
TextView Score = (TextView) findViewById(R.id.Score);
Score.setText(String.valueOf(scr));
aCounter.start();
}
});
}
Are you trying to make it so that if the user has already started the timer, subsequent button presses don't restart it from the first tap? If so, all you should have to do is put an if statement in your onclick that checks to see if the timer is still counting down, i.e. check and see if the current time is greater than 0 on the counter.
Edit: here's code
final CountDownTimer aCounter = new CountDownTimer(10000, 1000) {
private long timeLeft;
public long getTimeLeft() {
return timeLeft;
}
public void onTick(long millisUntilFinished) {
timeLeft = millisUntilFinished / 1000;
cm.setText("Time Left: " + timeLeft);
}
public void onFinish() {
cm.setText("Time's Up!");
}
};
aCounter.cancel();
tapBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (aCounter.getTimeLeft() == 0) {
scr = scr - 1;
TextView Score = (TextView) findViewById(R.id.Score);
Score.setText(String.valueOf(scr));
aCounter.start();
}
}
});
}
one way to do it is to create a flag that gets set on the first tap and have the onclick event flip the flag on the first click, and put the timer start inside of an if statement that only occurs if the flag hasn't been set.
