Answer 1

This problem has solved.

I later changed var intent = Intent() into var intent = getIntent(), then CategoryDetailRecyclerViewActivity can get intent.

Answer 2

I am unsure what you mean by why StartActivity(intent) failed but based on your Logcat, it prints what I would expect from the code.

First of all it doesn't fail. You see in the Log that the code inside the onCreate() is executed. So the activity is started.

D/CategoryDetailRecyclerViewActivity: Intent:Intent {  } 
D/CategoryDetailRecyclerViewActivity: categoryDesignID: null

Here you see one of the problems: Your categoryDesignID is null. That is because you are not reading it from the right place. To get the data from the intent you used to start an Activity, you should ask for the intent instead of creating a new one.

Change your onCreate code to this and is should at least log the right id value:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_category_detail_recycler_view)

    // don't create an Intent instance, it is already available and contains what you have send via startActivity(intent)
    // var intent = Intent()
    Log.d(TAG, "Intent:$intent ");
    var categoryDesignID = intent.getStringExtra("categoryDesignID")
    Log.d(TAG, "categoryDesignID: $categoryDesignID");
}
