How to "wait" a Thread in Android

private void startGameTimeElapseThread(){
    new Thread(new Runnable() {
        Date d = new Date();
        public void run() {
            while (gameOn){
                Log.d(TAG,""+d.getTime()+" "+gameStatus.getLastTimeUpdated());

                postInvalidate(795, 150, 1024, 300);
                try {
                    synchronized (this) {
                        wait(1000); 
                    }
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    Log.d(TAG, "Waiting didnt work!!");
                    e.printStackTrace();
                }
            }
        }
    }).start();
}

Here I wanted to make call the "Log.d" and "postInvalidate" every one second. But when i check it from LogCat it seems loop runs faster than i want it to be. Why doesnt this loop just wait for 1000ms ?

Following are the output in LogCat. So you can see its not sleeping for a 1 second at all. I used Thread.sleep as well ( after you suggesting )
