Splash screen stuck to the screen - intent to the main activity is not starting

Question

I was creating a splash screen in android using Thread.sleep(). (I know the another method - using handler, but I have to use this method for now.)

My code is as follows:

public class SplashScreen extends Activity { 
   Thread t;
             @Override
                protected void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.activity_spash_screen);

            new myclass();
        }
            class myclass implements Runnable{

                myclass()
                {
                t = new Thread();
                t.start();
                }

                public void run()
                {
                    try{
                        Thread.sleep(1000);
                    Intent i = new Intent(getApplicationContext(), MainActivity.class);
                       startActivity(i);
                       finish();
                    }
                    catch(InterruptedException e){
                    System.out.println("thread interrupted");

                    }
                    }

                }
            }

It does not show any error, but splash screen stuck to the screen.

After 1s, it did not start another intent.

If you know the mistake then please help me.

Try this,I always use this code in my Splash Activities.

 public class SplashScreen extends Activity
   {
private Thread mSplashThread;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash_screen);

    mSplashThread = new Thread()
    {
        @Override
        public void run()
        {
            try
            {
                synchronized (this)
                {
                    wait(2000);
                }
            }
            catch(InterruptedException ex) {
                ex.printStackTrace();
            }
            finish();
            startActivity(new Intent(getApplicationContext(),MainActivity.class));
        }
    };
    mSplashThread.start();
}

@Override
public boolean onTouchEvent(MotionEvent evt)
{
    if (evt.getAction() == MotionEvent.ACTION_DOWN)
    {
        synchronized (mSplashThread)
        {
            mSplashThread.notifyAll();
        }
    }
    return true;
}
    }

run method of runnable is not called because you are not passing runnable to Thread constructor. so pass it as:

            t = new Thread(this);
