Emoji Keyboard for Dialog Fragments

[eltos]

I tried to use EmojIconActions for a custom view in an AlertDialog, that I create during the onCreateDialog Method of DialogFragment.

I'm not sure what View to pass as the rootView parameter to the EmojIconActions constructor.
I tried using Fragment.getView(), but the keyboard does not shows up.
When using getActivity().findViewById(android.R.id.content) I can make the keyboard show up, but it appears in the dimmed background and also above the system-keyboard.

What view has to be passed as the rootView here?
