How to Add a Delay to Execute a Code After Sometime in Android Studio? Handler Class

Hi there! I'm delighted to share with you today a cool approach I discovered for utilizing a Handler to add a delay to code execution in Android Studio. Now let's get started.

handler to delay a code

To begin with, why would we wish to introduce a delay in the way the code executes? Well, sometimes we have to hold off on running some code till a particular thing happens or until a certain condition is satisfied. Delays are useful in situations like that.

In Android Studio, we can achieve this using a Handler. Here's how:

Handler handler =  new Handler(); //Can also be called in class variables to use in different methods
handler.postDelayed(new Runnable() {
@Override
    public void run() {
        if (anyInt == 1 || !anyString.isEmpty){ //any condition of your choice
            //Execute the code Here
        }
    }
}, 1000);//Delay Time in Milliseconds, 1000 = 1 sec

Let's break it down step by step:

  1. We start by creating a new Handler object and calling its postDelayed method.

  2. Inside postDelayed, we pass a new Runnable object. This is where our delayed code will be executed.

  3. In the run method of the Runnable, we put the code that we want to execute after the delay.

  4. In this example, we're checking if the item count is equal to

  5. The 1000 parameter passed to postDelayed represents the delay in milliseconds. So in this case, our code will be executed after a 1000 millisecond (1 second) delay.

  6. And there you have it! Adding a delay in executing code using a Handler in Android Studio is as simple as that. Happy coding!
