DialogFragment setCancelable属性不起作用

Question

我在一个android应用程序中工作，正在使用一个DialogFragment来显示一个对话框，我想让那个DialogFragment不可取消。我已经将对话框可取消属性设置为false，但它仍然不受影响。

请查看我的代码，并建议我一个解决方案。

public class DialogTest extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        return super.onCreateDialog(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.dialog_test, container, true);
        getDialog().requestWindowFeature(STYLE_NO_TITLE);
        getDialog().setCancelable(false);

        return view;
    }
 }

/**
 * Control whether the shown Dialog is cancelable.  Use this instead of
 * directly calling {@link Dialog#setCancelable(boolean)
 * Dialog.setCancelable(boolean)}, because DialogFragment needs to change
 * its behavior based on this.
 *
 * @param cancelable If true, the dialog is cancelable.  The default
 * is true.
 */
DialogFragment.setCancelable(boolean cancelable) {
    mCancelable = cancelable;
    if (mDialog != null) mDialog.setCancelable(cancelable);
}
