The exception guides you straight to the location where this error is coming from:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference
As per your code, there can be two ways to fix this,
keywordlist = findViewById(R.id.keywordlist);
Either, check that this keywordlist view has been inflated in the activity. Otherwise, if you are deep down in the hierarchy, try accessing this view from the view that your control is currently inside — happens with inflated views and layouts.

There are several other things that can go wrong, so best hands are still yours to find the bug, try debugging and seeing why is that object null.

java - Custom View children are null after inflating the view in Android - Stack Overflow
