Comment utiliser timeLeft pour reprendre countdowntimer sur Android?

Question

timeLeft fonctionne pour la lecture de fichiers musicaux, mais comment travailler avec onResume? Je peux donc mettre l'activité en pause, puis reprendre avec la minuterie de gauche.

Voici mon code:

public void countdownTimer() { 

    final TextView mTextField = (TextView)findViewById(R.id.timer); 
    Count = new CountDownTimer(TIMER, 1000) { 
     public void onTick(long millisUntilFinished) { 

      mTextField.setText("" +(millisUntilFinished/60000)); 
      long timeLeft = millisUntilFinished/1000; 
      if(timeLeft <= 4 && timeLeft >=2 && tgbutton.isChecked()) 
      { 
       mSoundPool.play(sixthMusicFile, 1f, 1f, 1, 0, 1f); 
      } 
      if(timeLeft <= 1 && tgbutton.isChecked()) 
      { 
       mSoundPool.play(seventhMusicFile, 1f, 1f, 1, 0, 1f); 
       vibrate(); 
      } 

     } 
     public void onFinish() { 
      Count.setText("done!"); 
     } 
     }.start(); 
} 

ÉDITÉ: Enfin, je me suis une réponse. Code de travail ici: Android CountDown Timer with Pause, Resume and Cancel button. Un grand merci à tous ceux qui m'aident avant.

essayer cette activité:

public class MyActivity extends AppCompatActivity { 

        long TIMER = 1000000; 
        long timeLeft = 0; 
        private CountDownTimer Count; 
        SharedPreferences sharedPreferences; 

        @Override 
        protected void onCreate(@Nullable Bundle savedInstanceState) { 
         super.onCreate(savedInstanceState); 
         sharedPreferences = getSharedPreferences("App_shared_preferenced", Context.MODE_PRIVATE); 

        } 

        @Override 
        protected void onResume() { 
         super.onResume(); 
         timeLeft= sharedPreferences.getLong("leftTime",0); 
         if(timeLeft>0) 
         countdownTimer(timeLeft); 
         else countdownTimer(TIMER); 
        } 

        @Override 
        protected void onPause() { 
         super.onPause(); 
         sharedPreferences.edit().putLong("leftTime",timeLeft).commit(); 
         if(Count != null){                 
          Count.cancel(); 
         } 
        } 

        public void countdownTimer(long t) { 
          if(Count != null) Count.cancel(); 
         final TextView mTextField = null;// Your text view 
         Count = new CountDownTimer(t, 1000) { 
          public void onTick(long millisUntilFinished) { 

           mTextField.setText("" + (millisUntilFinished/60000)); 
           timeLeft = millisUntilFinished/1000; 
           if (timeLeft <= 4 && timeLeft >= 2 && tgbutton.isChecked()) { 
            mSoundPool.play(sixthMusicFile, 1f, 1f, 1, 0, 1f); 
           } 
           if (timeLeft <= 1 && tgbutton.isChecked()) { 
            mSoundPool.play(seventhMusicFile, 1f, 1f, 1, 0, 1f); 
            vibrate(); 
           } 
          } 

          public void onFinish() { 
           Count.setText("done!"); 
           timeLeft = 0; 
          } 
         }.start(); 
        } 
       }
