android - How can I create positive and negative buttons at custom dialogs

Question

I want to create a custom dialog. So i create a template 'dialog_change' and I open the dialog.

Dialog myDialog = new Dialog(Overview.this);
myDialog.setContentView(R.layout.dialog_change);
myDialog.setTitle("My Custom Dialog Title");
myDialog.show();

Now i want to add two button (one positive and one negative button), at the bottom. How can i do that?

I'd just make your own custom class to simulate an AlertDialog, this way you can use your own layout with no strings attached. (There are some weird issues where you can't fully get rid of the frame if you want a fully styled AlertDialog). Something like this, but you can expand this as fully as you want:

public class CustomDialog extends Dialog {
    private Button positive, negative;

    public CustomDialog(Context context) {
        super(context);
        initialize(context);
    }

    protected CustomDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
        initialize(context);
    }

    public CustomDialog(Context context, int theme) {
        super(context, theme);
        initialize(context);
    }

    private void initialize(Context c) {
        //Inflate your layout, get a handle for the buttons

        positive = (Button)layout.findViewById(R.id.positive):
        negative = (Button)layout.findViewById(R.id.negative):

        positive.setVisibility(View.GONE);
        negative.setVisibility(View.GONE);
    }

    public void setPositiveButton(String buttonText, View.OnClickListener listener) {
        positive.setText(buttonText);
        positive.setOnClickListener(listener);
        positive.setVisibility(View.VISIBLE);
    }

    public void setNegativeButton(String buttonText, View.OnClickListener listener) {
        negative.setText(buttonText);
        negative.setOnClickListener(listener);
        negative.setVisibility(View.VISIBLE);
    }
}
