I'm having problems with running the code on my device [duplicate]

Answer 1

You are trying to cast a layout on a listview

add this @id into your LinearLayout and inflate it in your Activity

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@id/layout";
tools:context="com.delaroystudiuos.alarmreminder.MainActivity">

and then call it like this

LinearLayout ll = (LinearLayout) inflater.inflate(R.layout.layout, container, false);;

Answer 2

If you are trying to access your existing ListView item in the XML:

<ListView
android:id="@+id/list"
android:layout_below="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

You will need to instead use:

View view = inflater.inflate(R.layout.nav_events, container, false);    
eventListView = view.findViewById(R.id.list);

Answer 3

This is an issue:

eventListView = (ListView) inflater.inflate(R.layout.nav_events, container, false); 

You try to inflate listview but inflater returns you a LinearLayout a parent of all views. You need inflate the LinearLayout instead of listview and this is causes to cast exception.
