Can I run timer at different intervals of time?

Actually i wanted to ask can i give value from database to a timer delay?

    Timer timer = new Timer();
    TimerTask timerTask = new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                  // whatever
                    }
                }
            });
        }
    };
    timer.schedule(timerTask,2000,**myDelay**); //here at my delay

Here at myDelay, can i give different values through database? Or it must be fixed?

If you are to change the time all the time with different values, I suggest you use

schedule(TimerTask task, long time)

Everytime you have a new time from DB, just create a new Timer() like so

time = getNewTimeFromDB();
createNewTask(time);
....
private void createNewTask(long time) {
    Timer timer=new Timer();
    TimerTask timerTask=new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // whatever
                }
            });
        }
    };
    timer.schedule(timerTask,time);
}

The good thing about this is you don't have to cancel the timer every single time because it is meant to run once.

May you should change your approach to the problem, create a function to return the time from the database FunctionToGetDelayFromDB();

Timer timer=new Timer();
long time = FunctionToGetTimeFromDB();
TimerTask timerTask=new TimerTask() {
    @Override
    public void run() {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                    // whatever
                    timer.schedule(timerTask, System.currentTimeMillis() + FunctionToGetDelayFromDB());
                }
            }
        });
    }
};
timer.schedule(timerTask, System.currentTimeMillis() + FunctionToGetDelayFromDB());

This should work for what you want to achieve...
