kotlin & Java: How to hide the toolbar only for specific fragments


Since it is expected that we will continue to encounter implementations that do not display the toolbar only for specific fragments in Android development, we will summarize it below including a memorandum.

For kotlin


//I want to hide
(activity as AppCompatActivity?)!!.getSupportActionBar()!!.hide()

//I want to display
(activity as AppCompatActivity?)!!.getSupportActionBar()!!.show()

For Java


//I want to hide

//I want to display

That is all.

This is the article I referred to this time. Please refer to it for more details. (Java.) https://stackoverflow.com/questions/29128162/android-hide-toolbar-in-specific-fragment

We hope for your reference.
