Resources$NotFoundException: Resource ID #0x0 in AlertDialog

Question

I have a RecyclerView, and in its adapter, I have created something similar to an OnLongClickListener, which I am calling an OnEntryLongClick

Answer 1

Change getBaseContext() in the AlertDialog.Builder instantiation to the current Activity instance. For example:

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

An AlertDialog requires certain resources whose values are provided by the themes and styles attached to the Context it uses. The Context returned by getBaseContext() doesn't have those attached, but the Activity does. Indeed, whenever a Context is needed for a UI component - e.g., Dialogs, Views, Adapters, etc. - the current Activity is usually what you want to use.
