Customizing the Display Time of Toast

By default a toast is displayed for 1 or 2 seconds. We can customize this thime and can show the toast for longer time 5,10,20 seconds etc.

We use  CountDownTimer class for this purpose.


IT is an abstarct class you can see details  CountDownTimer

Display  Toast  for longer time

In this example we will show the toast for 20Seconds (20000 milliseconds)

public class ToastActivity extends Activity
    AlertDialog dialog;
     static CountDownTimer timer =null;
     Toast toast;
        public void onCreate(Bundle savedInstanceState)

                // creating toast and setting properties

                toast = new Toast(this);
                TextView textView=new TextView(this);
                textView.setText("This Toast will Display for 20 Seconds in Center of The Screen");
                toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);


               //    Toast Display tTime Settings

                // Create the CountDownTimer object and implement the 2 methods
                // show the toast in onTick() method  and cancel the toast in onFinish() method
                // it will show the toast for 20 seconds (20000 milliseconds 1st argument) with interval of 1 second(2nd argument)

                timer =new CountDownTimer(20000, 1000)
                    public void onTick(long millisUntilFinished)
                    public void onFinish()



We can also cancel our toast before specified tine of 20 Seconds  on a particular condition with following code

// Cancelling toast on a particular condition

                if(your conditinal expression)

  1. Where do you place the

    if(your conditinal expression)
    } ?

    I am new to Android programming.

  2. Thank you!!!! This saved me a TON of extra work.

  3. First, CountDownTimer is not really an abstract class. If it were, you would not be able to instantiate it with new, which you do in the code.
    Second, you need to show the toast you constructed before the timer is activated. Otherwise, the toast will be shown with approx. a 1-second delay, upon the first onTick() call.
    Finally, notice that if the duration is set to 5000 msec, you will only receive 3 onTick() callbacks, with just below 4, 3 and 2 seconds to finish (to prove this, insert a Log.d() statement into onTick() to print the remaining time). This means that the Toast has to sustain at least 2 seconds of showing by itself, which can be a problem with a default short duration setting. So, to be on the safe side, set the onTick interval to 500 not 1000 msec.
