AlertDialog like permission dialog in Android TV (Leanback) App

Question

I'm working on an Android TV project which is a leanback project basically.

I want to show an alert dialog similar to the permission dialog in android tv apps. see the image.

I tried adding normal AlertDialog like this:

AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
alertBuilder.setCancelable(true);
alertBuilder.setTitle("Permission necessary");
alertBuilder.setMessage("External storage permission is necessary");
AlertDialog alert = alertBuilder.create();
alert.show();

but that doesn't help. Can anyone show me the way to show similar AlertDialog in Android TV app?

You probably need to use a custom layout for this – MatPag Aug 20 '19 at 07:59 — MatPag, Aug 20 '19 at 07:59

I didn't find a solution and created a custom DialogFragment, Look at github

And now I can create the dialog I need like this

val dialogExit = LeanbackDialogFragment(R.string.dialog_exit, R.string.dialog_exit_d, R.drawable.ic_exit)
dialogExit.addButton(R.string.yes) { dialog, which ->
    exitProcess(0)
}
dialogExit.addButton(R.string.no)
dialogExit.addButton("I don't know")
dialogExit.show(requireActivity().supportFragmentManager)

Result

This is great! I will check this solution in my sample repository and will accept the answer if this works well. – Keval Langalia Feb 14 '22 at 01:28
@Tiarait Can you please make a java version of the ```LeanbackDialogFragment.kt```? – Omar Hemaia Aug 08 '22 at 23:03
