    super.onCreate(savedInstanceState);
    setContentView(R.layout.eventus_homeview);

    lstEvents = new ArrayList<>();
    lstEvents.add(new Events("Paramore Night","Concert","Paramore Covers",R.drawable.eve1));
    lstEvents.add(new Events("Paramore Night 1","Conference","Paramore Covers",R.drawable.eve2));
    lstEvents.add(new Events("Paramore Night 2.0","Camp","Paramore Covers",R.drawable.eve3));
    lstEvents.add(new Events("Paramore Night 2.5","Exhibit","Paramore Covers",R.drawable.eve4));

    lstEvents.add(new Events("Paramore Night 3.0","Concert","Paramore Covers",R.drawable.eve5));


    RecyclerView myrv = (RecyclerView)findViewById(R.id.recyclerViewEvents);
    RecyclerViewAdapter myAdapter = new RecyclerViewAdapter(this, lstEvents);
    myrv.setLayoutManager(new GridLayoutManager(this,3));
    myrv.setAdapter(myAdapter);

}

}

can you please help me how to deal with this? I've been stuck with this for an h our already.

Answer 1

If you have such long exceptions, always look at the last Caused bywhich will tell you the actual reason of the exception. There, it says:

Caused by: android.content.res.Resources$NotFoundException: Resource "com.example.jevaltamidles.eventus:drawable/rectangle_button" (7f06006d) is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f06006d a=-1 r=0x7f06006d}

That means that there's something wrong with your com.example.jevaltamidles.eventus:drawable/rectangle_button. In your xml, you are expecting the rectangle_button to be a drawable, but clearly it's not a drawable but something else.
