How do i exit runnable and switch another activity

Question

I have a textview timer, i want it stops after 10 seconds of showing on display and after 10 seconds that my current activity jumps to an other activity

Runnable runnable = new Runnable()
    {
        @Override
        public void run()
        {
            while(Running)
            {
                try{
                Thread.sleep(1000);
            }catch(InterruptedException e)
            {
                e.printStackTrace();
            }
                handler.post(new Runnable()
                {
                    @Override
                    public void run()
                    {
                        number+=1;
                        tvTimer.setText(String.valueOf(number)); //With setting value of number on textfield ITS POSSIBLE TO SEE THE TIMER
                        if(number==10)
                        {
                            Running = false;
                            handler.removeCallbacks(this);//that does not works for me to stop 

                            Intent i = new Intent(getApplicationContext(), SonucMenu.class); 
                            startActivity(i); //Starting my second class

                        }
                    }

                });

            }

        }

My Second activity starts but the layout from second activity comes more than one time, what i want is that it comes only one time, and i think this problem depends on that i cant stop runnable

Runnable stops, when it reaches the last line of `run`. Which `run` method do you think does not stops and why? — Smutje, Oct 19 '14 at 00:00
I want when variable number (counter) stops when it is 10, that case is in my inner run method which starts with number+=1 — tuna, Oct 19 '14 at 00:09

Nitesh Singh · Accepted Answer · 2014-10-19T12:19:39.803

I think for this you can use following code , It worked for me.
It will start your activity after 10 seconds.

new Handler().postDelay(new Runnable() {          
@Override
public void run() {

Start Your activity here.

    }
}, 10000);

but one of the best solution will be (I just found it from develoer site):

new CountDownTimer(10000, 1000) {

 public void onTick(long millisUntilFinished) {
     mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
 }

 public void onFinish() {
     strat your activity here.
 }

}.start();

Use View.post(Runnable) and View.postDelayed(Runnable, long), no need to create additional thread.

private TextView tvTimer;
private final Runnable mCountDownRunnable = new Runnable() {
    private int mCount = 0;
    @Override
    public void run() {
        mCount++;
        if (mCount < 10) {
            tvTimer.setText(Integer.toString(mCount));
            tvTimer.postDelayed(this, 1000);
        } else {
            Intent i = new Intent(YourActivity.this, SonucMenu.class);
            YourActivity.this.startActivity(i);
        }
    }
};

to start runnable, call tvTimer.post(mCountDownRunnable);

this code looks good but while starting " YourActivity.this.startActivity(i);" app shuts down – tuna Oct 19 '14 at 11:01
rename `YourActivity` with the class name of your activity. – biegleux Oct 19 '14 at 11:11
That i have done too in my case MainActivity.this.startActivity(i); unfortunately it doesnt work :( – tuna Oct 19 '14 at 11:28
post logcat or more code, did you define runnable as a member of your activity? what about `SonucMenu`? – biegleux Oct 19 '14 at 11:30
I posted complete original Code over – tuna Oct 19 '14 at 11:55
why `SonucMenu` extends `MainActivity`? – biegleux Oct 19 '14 at 12:02
it was not an intention to do extends MainActivity, i used it before when i was challenging with multiactivity but now i know extends MainActivity is not useful, i must needed to add SonucMenu.java to AndroidManifest.xml, thank u for help – tuna Oct 19 '14 at 15:32

How do i exit runnable and switch another activity
