/**
 * Dialog window to create a dialog with a custom view.
 *
 * <p>After pressed the OK button, the result will be returned 
 * inside a bundle under the key 'DIALOG_RESULT_VALUE'.
 * 
 * <p>This dialog will show your custom view inside a dialog with two buttons. 
 * The cancel button simply close the dialog, the OK button dismiss the dialog and
 * call your callback method (<code>DialogResultListener.onDialogDone</code>).
 * 
 * <p>Example:
 * 
 * <p><pre>
final EditText editText = new EditText(context);
