Implementation Function Handler Android (show anything after a few second)

Hello world. Today its my second post, ya i wanna show you how to implementation function handler on the android programming. If you don't know about handler, handler is like function that you can use, if you want to show anything, with period. For example i wanna show snackbar or anything after 3 second. Lets do it.

Ahha, i've handler function like this.

private void handlerFunction(final View v){
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                Snackbar.make(v, "Hi i am show after  3 second", 
                        Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        }, 3000);
    }

On this function, i just 3000 millisecond its mean 3 second waiting. And after that snackbar will show like this "Hi i am show after 3 second". Like this picture.

If you want to show anything, you put inside run function. Just it. Write comment bellow if still confuse about my code, or comment on my Github page. I hope this is can help you little bit. Lol. Thanks.
