Resources$NotFoundException: Resource ID #0x0 in AlertDialog

I have a RecyclerView, and in its adapter, I have created something similar to an OnLongClickListener, which I am calling an OnEntryLongClickListener to avoid confusion.

I am using an AlertDialog to display a dialog with list items for different actions. However, I am getting the following error:

E/AndroidRuntime: android.content.res.Resources$NotFoundException: Resource ID #0x0  
    at android.content.res.Resources.getValue(Resources.java:2345)  
    at android.content.res.Resources.loadXmlResourceParser(Resources.java:3910)  
    at android.content.res.Resources.getLayout(Resources.java:2161)  
    at android.view.LayoutInflater.inflate(LayoutInflater.java:413)  
    at android.view.LayoutInflater.inflate(LayoutInflater.java:366)  
    at android.support.v7.app.AlertController$AlertParams.createListView(AlertController.java:734)  
    at android.support.v7.app.AlertController$AlertParams.apply(AlertController.java:711)  
    at android.support.v7.app.AlertDialog$Builder.create(AlertDialog.java:883)
    at com.mycompany.myapp.ThisActivity$2.onEntryLongClick(ThisActivity.java:135)  
    at com.mycompany.myapp.adapter.RVAdapter$RVViewHolder.onLongClick(RVAdapter.java:41)   
    at android.view.View.performLongClick(View.java:5236)  

Below is the relevant code I am using:

adapter.setOnEntryLongClickListener(new RVAdapter.OnEntryLongClickListener() {
    @Override
    public void onEntryLongClick(View view, int position) {
        final MiniEntry thisEntry = entryList.get(position);
        AlertDialog.Builder builder = new AlertDialog.Builder(getBaseContext());
        builder.setTitle(thisEntry.getEntryName()););
        builder.setItems(R.array.quickActions, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // Other code here
            }
        });
        AlertDialog alert = builder.create(); // The error log points to this line
        alert.show();
    }
});
mRecyclerView.setAdapter(adapter);

As well as the XML I am using for the array:

<string-array name="quickActions">
    <item>Add to Favourites</item>
    <item>More information</item>
</string-array>

I'm not sure if it matters, but I am importing the AlertDialog from android.support.v7.app.AlertDialog (from the v7 Support Library).

How can I solve this problem?

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.

Try putting an style for your Dialog that extends Theme.AppCompat.Light.Dialog.Alert

<style name="MyDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert" />

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.MyDialogTheme);

This works for me.
