I'm new to android studio and I'm trying to remove a button from my videos app

I have 4 buttons in my app Android : Recent,Featured,Popular,Random and Live.

I would like to delete the Live button, but I am not able to

If necessary I can take a screenshot of my android studio.

I don't necessarily need to remove the button if I have another way to just hide it, that would be a big help too

I followed my code:

If you know id of the button.

 view.findViewById(R.id.btn_firs).setVisibility(View.GONE);

From my understanding, you don't want to remove a classic button, but a Tab button used inside a TabLayout.

If you want to remove it , easiest way would be to remove the last condition in your if else statements that deal with displaying and handling this button.

From the code you posted should be

Here

{
            return getResources().getString(R.string.menu_live);
}

and here, as i think these two deal with the "Live" button.

{
            return Fragmentvideo.newInstance(ORDER_LIVE, FILTER_LIVE);
}

As well as reduce the value passed to the ViewPager Adapter "noOfItems" variable by 1. In your situation, I think the variable is "tabCount" and that should be set to 4 ( down from 5). I see it's used in many places and changing this should deal with all cases.

If hiding is also good, then this code should also work.

Just use it inside onCreateView(). The code is in Kotlin and works on a default TabLayout, but i am not sure if it will work as i see you use a custom one.

tabLayout?.getTabAt(4)?.view?.visibility = View.GONE

You need to pass the index of the tab you want to hide, so in your case, you have 5 tabs, so the index is 4.
