Toast context inside onFocusChangeListener

[Muhammad Imad Qureshi]

I am inside onFocusChangeListenerMethod inside my activity class. How do I get access to my activity object to use in Toast.makeText() method? What other ways are there to display an error message (user has entered incorrect text). Here is my code
I have commented the code in "else" part that I want to fix.

Thanks
Imad

    values.setOnFocusChangeListener(new View.OnFocusChangeListener() {
			
			@Override
			public void onFocusChange(View v, boolean hasFocus) {
				// TODO Auto-generated method stub
				if ( !hasFocus && ! values.getText().toString().equals("") ){
					if ( Utilities.areAllElementsNumeric(values.getText().toString()) ){
						attemptCalculation ();
						valuesEntered = true ;
						values.setBackgroundColor(Color.GRAY);
					}
					else{
						valuesEntered = false ;
						values.setBackgroundColor(Color.RED);

                                                //this wont work. it throws and exception and ends the program
						Toast.makeText(getApplicationContext(), "Invalid Value(s) Entered in \"Values\" Field", Toast.LENGTH_LONG).show();
					}
				}
			}
		});

Hi,Imad

Toast.makeText(getApplicationContext(), "Invalid Value(s) Entered in \"Values\" Field", Toast.LENGTH_LONG).show();

i hope your application is extending Activity (any of android activity) then, instead of writing getApplicationContext() try following this will work.

 Toast.makeText(this, "Invalid Value(s) Entered in \"Values\" Field", Toast.LENGTH_LONG).show();

"this" is not working because I am inside a listener.

Imad, can you show class code and Log (error) here,that will help us to find the problem solution.
one solution: create class variable Context and set it inside onCreate(); use this variable in your Toast.makeText(getApplicationContext(), "Invalid Value(s) Entered in \"Values\" Field", Toast.LENGTH_LONG).show();

Thanks for your reply. I resolved it with the following code. I think you are right. I should be able to use getApplicationContext() too. But this is what I did.

    
if ( !hasFocus && ! values.getText().toString().equals("") ){
					if ( Utilities.areAllElementsNumeric(values.getText().toString()) ){
						valuesEntered = true ;
						values.setBackgroundColor(Color.WHITE);
						attemptCalculation ();
					}
					else{
						valuesEntered = false ;
						values.setBackgroundColor(Color.RED);
						Toast.makeText(getOuterClassObject(), "Invalid Value(s) Entered in \"Values\" Field", Toast.LENGTH_LONG).show();
					}
				}

private MIRRActivity getOuterClassObject (){
		
		return this ;
