Call Instance of View (Switch) located in Adapter's ViewHolder in the Activity that utilizes Adapter

[Adam Wentz]

Is there a way for me to get an instance of the switch in my Adapter, in my Activity?

I created an instance of my Adapter's ViewHolder in my Activity:

ApplicationsAdapter.ViewHolder viewHolder = new ApplicationsAdapter.ViewHolder();

Then I set up an onClickListener for the switch in my Activity's onCreate method:

viewHolder.appSwitch.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
 
                if (viewHolder.appSwitch.isChecked()) {
                    //do stuff
                } else {
                    //do other stuff
                }
            }
        });

However, I am getting a NullPointerException on the Switch. What am I missing?

You mean you want to use the switch in your Activity where the switch is declared in Adapter ?

Yes, the Switch is a View of the row layout for my RecyclerView. I want to be able to add an onClickListener to it in my Activity instead of doing it in the Adapter.
