Question

I have a custom dialog inside

public class NewPartnerDialog extends Dialog implements OnClickListener

And I call it from other class (activity)

private void showCustomDialog() {
    NewPartnerDialog customDialog = new NewPartnerDialog(this);
    customDialog.show();
}

And it works (it does show), but I have a little problem. In it I have 3 EditText fields. How can I retreieve those typed values and pass them into some other class construtor. Here is the code.

public class NewPartnerDialog extends Dialog implements OnClickListener {
public NewPartnerDialog(Context context) {
    super(context);
    mainContext = context;

    setContentView(R.layout.dialog_new_partner);
    setTitle("Dialog");

    finish = (Button) findViewById(R.id.finish);
    cancel = (Button) findViewById(R.id.finish);
    finish.setOnClickListener(this);
    cancel.setOnClickListener(this);

    name = (EditText) findViewById(R.id.name);
    address = (EditText) findViewById(R.id.address);
    city = (EditText) findViewById(R.id.city);
}

@Override
public void onClick(View v) {       
    if (v == finish) {
        Partner.addNewPartner(mainContext, name.getText().toString(), address.getText().toString(), city.getText().toString());
    } else if (v == cancel) {
        dismiss();
    }
}

private static EditText name;
private static EditText address;
private static EditText city;
private static Context mainContext;
private Button finish;
private Button cancel;

}

The error is obivusly here

if (v == finish) {
        Partner.addNewPartner(mainContext, name.getText().toString(), address.getText().toString(), city.getText().toString());
    }

because it says NullPointerException but how to fix it?

Answer 1

Try making name, address, and city final:

private static final EditText name, address, city;

Not certain that will do the trick, but you may try.

EDIT: You may need to make finish and cancel final as well.
