Get variable from countdown and set it to TextView

I need your help to get a variable from the countdown and set that value to text view. Suppose if countdown stopped at 0:40 sec and I want to put that number to text view.

So I'm using Seekbar to update the time with progress and a textview. And suppose I stopped at a certain number, next time I start again, let the number start from when it stopped. I have uploaded the image of output. Thanks

I learned to create this app from udemy online tutorial. Its called Complete android developer course- Build 23 Apps!!. Its lesson 38- App Egg timer.

This is my MainActivity.java file

public class MainActivity extends AppCompatActivity {
TextView timerTv;
SeekBar timerSeekBar;
Button startBtn;
CountDownTimer countDownTimer;
boolean counterisActive = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
timerTv = (TextView) findViewById(R.id.countdowntimertextview);
timerSeekBar = (SeekBar) findViewById(R.id.timerSeekBar);
startBtn = (Button) findViewById(R.id.startBtn);
timerSeekBar.setMax(300);
timerSeekBar.setProgress(20);
timerSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
updateTimer(progress);
Log.i("Seekbar changes", String.valueOf(progress), null);
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
public void resetTimer(){
//This is where I want to set the text.
timerTv.setText("Trying to get text from countdown!!");
startBtn.setText("START!");
timerSeekBar.setEnabled(true);
countDownTimer.cancel();
timerSeekBar.setProgress(20);
counterisActive = false;
}
public void buttonClicked(View view){
if(counterisActive){
resetTimer();
}else {
counterisActive =  true;
timerSeekBar.setEnabled(false);
startBtn.setText("STOP!");
Log.i("Button Clicked", "Clicked");
countDownTimer = new CountDownTimer(timerSeekBar.getProgress() * 1000 + 100, 1000) {
@Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
}
@Override
public void onFinish() {
MediaPlayer mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.templebell);
mediaPlayer.start();
Log.i("Timer Finished", "Done!!");
resetTimer();
}
}.start();
}
}
public void updateTimer(int secondLefts){
int minutes = secondLefts / 60;
int seconds = secondLefts - (minutes * 60);
String secondString = Integer.toString(seconds);
if(seconds <= 9) {
secondString = "0" + seconds;
}
timerTv.setText(minutes + " : " + secondString );
}
}

I think you need to pause the timer.
First create a global long variable in your activity;

long timerProgress;

Change your restProgress() method like below, or you can add new method pauseTimer().

public void restTimer(){
//This is where I want to set the text.
updateTimer((int) timerProgress/1000);
startBtn.setText("START!");
timerSeekBar.setEnabled(true);
countDownTimer.cancel();
timerSeekBar.setProgress((int) timerProgress/1000);
counterisActive = false;
}

Know add this line to your override method onTick.

@Override
public void onTick(long millisUntilFinished) {
updateTimer((int) millisUntilFinished / 1000);
// add this line for store progress timer.
timerProgress = millisUntilFinished;
}

• You can add another button one for pause and other for rest Timer.

Try replacing timerTv.setText(minutes + " : " + secondString ); with

runOnUiThread(new Runnable() {
@Override
public void run() {
timerTv.setText(minutes + " : " + secondString );
}
});

If you try to update the UI mid-thread, it will wait until the current thread has finished before updating the text.
