How to get rid of the resource not found exception when clicked on item view on recycler view and instead of data and activity lauch, it crashes app

Question

I have built an app to learn the use of adapter and recycler view. It contains a recycler view and adapter, it uses data class to show data on clicked to an item of the recycler view, but the app crashes on runtime whenever I click on an item of the recycler view and showing java resources not found exception, could any one please help me out from this because I am a newbie to learning and debugging this

You are trying to access non-existing resource `Resource ID #0xffffffff`. It's hex representation of value `-1` — xinaiz, Jul 24 '22 at 10:55

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.planetapp/com.example.planetapp.PlanetDetail}: android.content.res.Resources$NotFoundException: Resource ID #0xffffffff
Caused by: android.content.res.Resources$NotFoundException: Resource ID #0xffffffff

The error above tells you what is really happening.

You are trying to access a "resource" using findViewById(int id) when it's not existing at all.

I recommend double-checking your code that uses findViewById(...) especially the code that intercepts the onClick(View view) event.

For example if you have an xml element with an ID like this:

<... android:id="@+id/MY_EXCELLENT_ID" ... />

You might've typed it like this:

findViewById(R.id.MY_EXCELLEND_ID);
