As you switch from your MainActivity context changes, you have to use your AdapterClass > ViewHolderClass > ViewHolder's constructor argument to get context for adapter.
Here is an example.
public MyViewHolder(final View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(itemView.getContext(),"Hi",Toast.LENGTH_LONG);
}
});
}
otherwise you can also pass context to a constructor argument for any other class not having activity.
example.
public class MyClass {
Context c;
public MyClass(Context context) {
c = context;
}}
Replace this line:
Toast.makeText(getApplication(), "Clicked Laugh Vote", Toast.LENGTH_SHORT).show();
with this line:
Toast.makeText(v.getContext(), "Clicked Laugh Vote", Toast.LENGTH_SHORT).show();
You can also use parent.getContext(), full code of toast is like below
Toast.makeText(parent.getContext(), "view clicked", Toast.LENGTH_SHORT).show();
