How To Pause And Start The Timer In Android?

I am working on android applications. In my project I have 3 pages. The first page consists of 1 button. The second page is consists of the timer code. The third page consis

Solution 1:

You can always store the timeLeft which is s1 and use it again like this, Read the comments too

1) While calling timer,check if you have any stored time

    Page1.java       
    rowTextView.setOnClickListener(newOnClickListener() { 
      publicvoidonClick(View v) { 
        SharedPreferencessp= PreferenceManager.getDefaultSharedPreferences(this);
        longtime= sp.getLong("time", 0); // get saved time of timesIntentmyIntent=newIntent(v.getContext(),Page3.class); 
        myIntent.putExtra("time", time); // send it to page2
        startActivity(myIntent); 
        finish();                                        
      } 
    }); 

2) Use the time to start time if it's not 0.

    Page2.java 

    publicclassTimeractivitybestActivityextendsActivity {
        EditText e1;
        MyCount counter;
        Long s1;

        @OverridepublicvoidonCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            longtime=this.getIntent().getLongExtra("time", 0); // get// saved// time
            time = (time != 0) ? time : 1500;
            e1 = (EditText) findViewById(R.id.editText1);
            counter = newMyCount(time, 1000); // start with saved time
            counter.start();
        }

        publicvoidmethod(View v) {

            switch (v.getId()) {

            case R.id.button1:
                counter.cancel();
                break;
            case R.id.button2:
                counter = newMyCount(s1, 1000);
                counter.start();
            }
        }

        publicclassMyCountextendsCountDownTimer {
            publicMyCount(long millisInFuture, long countDownInterval) {
                super(millisInFuture, countDownInterval);
            }

            @OverridepublicvoidonFinish() {
                e1.setText("DONE");
            }

            @OverridepublicvoidonTick(long millisUntilFinished) {
                s1 = millisUntilFinished;
                e1.setText("left:" + millisUntilFinished / 1000);
            }
        }

        publicvoidonPause() {
            SharedPreferencessp= PreferenceManager
                    .getDefaultSharedPreferences(this);
            Editoret= sp.edit();
            et.putLong("time", s1); // save time SharedPreference in onPause
            et.commit();
        }

    }

3) no change in page 3, I suppose.

    Page3.java 

    publicvoidgobacktopage1(View v){ 
            Intent myIntent = newIntent(v.getContext(),Page1.class); 
            startActivity(myIntent); 
            finish(); 
        } 

Solution 2:

publicclassTimerActivityextendsActivity{

EditText e1;
MyCount counter;
Long s1;
/** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    e1=(EditText)findViewById(R.id.editText1);
    counter= newMyCount(5000,1000);
    counter.start();
}
publicvoidasdf(View v)
{
    switch(v.getId())
    {
        case R.id.button1:         counter.cancel();
        break;
        case R.id.button2:         counter= newMyCount(s1,1000);
        counter.start();
    }
}
publicclassMyCountextendsCountDownTimer
{
    publicMyCount(long millisInFuture, long countDownInterval)
    {
        super(millisInFuture, countDownInterval);
    }
    @OverridepublicvoidonFinish()
    {
        e1.setText("DONE");
    }
    @OverridepublicvoidonTick(long millisUntilFinished)
    {
        s1=millisUntilFinished;
        e1.setText("left:"+millisUntilFinished/1000);
    }
}

}

Solution 3:

this is how it works...

MyCount counter;
Long s1;

     counter= newMyCount(300000,1000);
    counter.start();

publicvoidasdf(View v){  <---- method for onclick of buttons pause and resuming timer

    switch(v.getId()){



    case R.id.button1:<-- for pause

        counter.cancel();
        break;
    case R.id.button2:<--- for resume
        counter= newMyCount(s1,1000);
         counter.start();
    }
}
publicclassMyCountextendsCountDownTimer{
    publicMyCount(long millisInFuture, long countDownInterval) {
    super(millisInFuture, countDownInterval);
    }
    @OverridepublicvoidonFinish() {
    mediaplayer.stop();
   mediaplayer.release();
    }
    @OverridepublicvoidonTick(long millisUntilFinished) {
        s1=millisUntilFinished;

    }
    }

case R.id.button1:<-- for pause

        counter.cancel();

this the one which is used to pause the timer and start again...

and in ur case

public void gobacktopage1(View v) { Intent myIntent = new Intent(v.getContext(),Page1.class); startActivity(myIntent); finish(); }

write a method in that add counter.cancel(); in that method and call that method...
