What I normally like to do is set the onClickListener programmatically

myButton.setOnClickListener(v -> handleMyButtonClick());

Since you are new to Java you may not be familiar with lambdas. So your code could also look more like is.

myButton.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
      // maybe call handleMyButtonClick();
    }
};

The onClickListener has to be set after the button has been initialized but before you actually click it.

  • Thanks for respond, I have a custom volume seekbar not button , Basically i need a code in which my seekbar works from any activity layout i have declared (xml layout) regardless of declaring repeatedly in all the activities. – user9330612 Nov 17 '21 at 06:15

You need to create object of your Activity, By using this Object you are able to use activity method.

Use this to call your Button's OnClick Action.
