Java – Android dialog box and EditText value?

I have a problem saving the string value located in EditText

The dialog box shows that you can use edit text, OK, and cancel button

What I want to happen when I press the OK button is that the bar variable gets the string value from EditText

public void dialog(){

    final Dialog dialog = new Dialog(myClass.this);
    dialog.setContentView(R.layout.mydialog);
    dialog.setTitle("I'm soo smart. S-M-R-T. Smart.");
    dialog.setCancelable(true);
    dialog.show();
    Button okButton = (Button) dialog.findViewById(R.id.dialog_OK_BUTTON);
    okButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            try{

                LayoutInflater factory = LayoutInflater.from(Inloggning.this);
                final View textEntryView = factory.inflate(R.layout.myDialog,null);
                final EditText barText= (EditText) textEntryView.findViewById(R.id.dialog_FOO);


                // this gets returned empty.
                bar= barText.getText().toString();


                System.out.println("foo: "+bar);


                //call();
                dialog.hide();

            }
            catch(Exception e){

                // do whatever nessesary.
            }

        } 
    });

    Button cancelButton = (Button) dialog.findViewById(R.id.dialogbtn_cancel);
    cancelButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            dialog.dismiss();
        }
    });



}

Does anyone know anything about this?

Editor: This is the sample code The actual code does not have duplicate names on variables

2nd edit: delete duplicates

Solution

Check if bartext is null

What happens if it is declared from the onclick listener?

Maybe change:

final EditText barText= (EditText) textEntryView.findViewById(R.id.dialog_FOO);

To:

final EditText barText= (EditText) dialog.findViewById(R.id.dialog_FOO);
