How to keep an alertdialog open after button onclick is fired?

The subject kinda says it all.. I'm requesting a PIN code from the user, if they enter it, click the OK Positive Button and the PIN is incorrect I want to display a Toast but keep the dialog open. At the moment it closes automatically.. Sure this is very trivial thing to correct but can't find the answer yet.

Thanks..

You can set an OnClickListener as follows to keep the dialog open:

public class MyDialog extends AlertDialog {
    public MyDialog(Context context) {
        super(context);
        setMessage("Hello");
        setButton(AlertDialog.BUTTON_POSITIVE, "Ok", (new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // this will never be called
            }
        });
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (ok) {
                    // do something
                    dismiss();
                } else {
                    Toast.makeText(getContext(), "when you see this message, the dialog should stay open", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }
}

Same problem for me in a FragmentDialog. Here's my criminal/elegant solution: Remove all buttons from the dialog (positive,negative,neutral). Add your buttons from the xml.eg.:

<LinearLayout
        android:layout_width="match_parent"
        android:orientation="horizontal"
        android:layout_height="wrap_content">
        <Button
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:id="@+id/button_cancel"
            style="@style/Widget.AppCompat.Button.Borderless.Colored"
            android:text="@android:string/cancel"
            android:layout_gravity="left"
            />
        <Button
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:id="@+id/button_ok"
            style="@style/Widget.AppCompat.Button.Borderless.Colored"
            android:text="@android:string/ok"
            android:layout_gravity="right"
            />
    </LinearLayout>

And then in your code handle it with:

view.findViewById(R.id.button_ok).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view2) {
                    if (wannaClose)
                        dismiss();
                    else
                        //do stuff without closing!
                }
            });

where view is the view assigned to the dialog!
