Dialog throwing "Unable to add window — token null is not for an application” with getApplication() as context

Question

My Activity is trying to create an AlertDialog which requires a Context as a parameter. This works as expected if I use:

AlertDialog.Builder builder = new Al         


        

Answer 1

If your Dialog is creating on the adapter:

Pass the Activity to the Adapter Constructor:

adapter = new MyAdapter(getActivity(),data);

Receive on the Adapter:

 public MyAdapter(Activity activity, List dataList){
       this.activity = activity;
    }

Now you can use on your Builder

            AlertDialog.Builder alert = new AlertDialog.Builder(activity);
