java.lang.ClassCastException: android.app.ContextImpl cannot be cast to "Activity" on ImageButton Android

Question

I have an array adapter and inside it an Imagebutton listener calling an activity.

Above my ListView I have and a input search of a ListView item.

When I search for an item by typing the initial letters and Click on Image Button

viewHolder.discounts.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            Intent intent = new Intent(getContext(), DisplayDiscounts.class);
            intent.putExtra("CustomerId",String.valueOf(cu.getId()));
            ((Customers) getContext()).startActivity(intent);

        }
    });

I get java.lang.ClassCastException: android.app.ContextImpl cannot be cast to "ActivityName"

How I can fix this?

Can I stop the input search when item found?

Your cast here is the problematic part:

((Customers) getContext()).startActivity(intent);

just drop the cast and use getContext().startActivity(..) instead.

Now I get Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. – Mr Teacher Jul 08 '16 at 16:11
are you calling this from a service? what's the context? – Nima Jul 08 '16 at 16:13
from array adapter – Mr Teacher Jul 08 '16 at 16:15
but what if the single adapter is used in for multiple Activities? – Faisal Naseer Aug 15 '18 at 11:43

You can either pass an Activity reference to your activity or try ((Customers) v.getContext()).startActivity(intent);
