Being a begginer in android , i have been stuck while using Toast.makeText ,here is the code.
public class CustomOnSelectedListen implements OnItemSelectedListener{
public void onItemSelected(AdapterView<?> parent, View view,int pos,long id){
Toast.makeText(parent.getContext(),
"OnItemSelectedListener :" + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?> arg0){
Toast.makeText(CustomOnSelectedListen.this,"Please select place and class".toString(),Toast.LENGTH_SHORT).show();
}
}
and the error is
Error:(19, 15) error: no suitable method found for
makeText(CustomOnSelectedListen,String,int)
method Toast.makeText(Context,CharSequence,int) is not applicable
(argument mismatch; CustomOnSelectedListen cannot be converted to Context)
method Toast.makeText(Context,int,int) is not applicable
(argument mismatch; CustomOnSelectedListen cannot be converted to Context)
Here CustomOnSelectedListen cannot be converted, what might be wrong?
EDIT 1: Yes CustomOnSelectedListen was not an context instance , i need to display a message in the function onNothingSelected() using toast,what are the different ways to do it?

On your onNothingSelected
function:
Toast.makeText(CustomOnSelectedListen.this,"Please select place and class".toString(),Toast.LENGTH_SHORT).show();
First parameter (CustomOnSelectedListen.this
) is not a Context
instance.
