I have a problem with countdown timer.I try some of solutions and articles in this site but they never worked for me. so, please read my codes...
also I used
handler.postDelayed(new Runnable() {
before and it was not my solution but it just worked correctly.
Main question is:
I want to do something like below:
(button pressed)
do some codes1
delay1
do other codes2
delay2
go back to *do some codes1* again.
In short, this is my real code:
itimesec--;
setdelay();
irepeat--;
setrelax();
and this is in my functions:
public void setrelax(){
CountDownTimer yourCountDownTimer1 = new CountDownTimer(50000, 1000) {
public void onTick(long millisUntilFinished1) {
itotalsnozee--;
TextToSpeechFunction(" "+itotalsnozee);
}
public void onFinish() {
itotalsnozee=fitotalsnozee;
isrelax=false;
TextToSpeechFunction("do again");
}
}.start();
yourCountDownTimer1.cancel();
}
I tried to use a variable insted of 50000 but it was not useful anyway.
I tried to put setrelax funtion codes directly into oncreate but it never worked.
it just jumped to
}.start();
yourCountDownTimer1.cancel();
every times and go out.
I tried all the codes without any delay function and they runned correctly.
what is my wrong please...
You need to remember that your code won't be executed sequentially when using the CountDownTimer
because it's working asynchronously (via Handler).
Let's dissect your code. Your following code here:
public void setrelax(){
// 1. Creating CountDownTimer
CountDownTimer yourCountDownTimer1 = new CountDownTimer(50000, 1000) {
public void onTick(long millisUntilFinished1) {
// 2. onTick called
...
}
public void onFinish() {
// 3. onFinish called
...
}
}.start();
// 4. CountDownTimer is cancelled.
yourCountDownTimer1.cancel();
}
will be running in the following sequences:
- Creating CountDownTimer
- CountDownTimer is cancelled.
- onTick called 49 times repeatedly (50000/1000 = 50 - 1 ).
- onFinish called
So, change your algorithm to something like this:
do some codes1
delay1
--> When delay finished, do other codes2. Then do delay2
You need to call the next code in the CountDownTimer.onFinish()
I looked at your code and I could not find any big mistakes but try this instead
Instead of
.start();
use
yourCountDownTimer1.start();
and remove yourCountTimer1.cancel();
like this :
public void setrelax(){
CountDownTimer yourCountDownTimer1 = new CountDownTimer(50000, 1000) {
public void onTick(long millisUntilFinished1) {
itotalsnozee--;
TextToSpeechFunction(" "+itotalsnozee);
}
public void onFinish() {
itotalsnozee=fitotalsnozee;
isrelax=false;
TextToSpeechFunction("do again");
}
};yourCountDownTimer1.start();
}
Hope it helps.
below is the code for running otp timer in our code.you can copy paste i have mentioned the comments please follow the same.
CountDownTimer countDownTimer; //define countDownTimer
countDownTimer.start(); // start countdown timer on some event like on click
String x="Your code will expire In";
String y="mins";
counttimer(); call the method counttimer which includes all the code of timer
public void counttimer(){
countDownTimer = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
String text = String.format(Locale.getDefault(), x+" %02d : %02d "+y,
TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished) % 60,
TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) % 60);
phonever_timer.setText(text); //set timer into textview object
}
public void onFinish() {
phonever_timer.setText("Otp Expired..!");
}
};
