如何调用getDialog.dismiss从另一个类(非嵌套的)中的AsyncTask类中清除对话框片段？

public interface DialogDismissListener {
    void onDismissDialog();
}

public class YourDialogFragment extends DialogFragment implements DialogDismissListener {
    // 其他代码...

    @Override
    public void onDismissDialog() {
        if (getDialog() != null) {
            getDialog().dismiss();
        }
    }
}

public class YourAsyncTask extends AsyncTask<Void, Void, Void> {
    private DialogDismissListener dismissListener;

    public void setDismissListener(DialogDismissListener listener) {
        this.dismissListener = listener;
    }

    // 其他代码...
}

YourAsyncTask asyncTask = new YourAsyncTask();
YourDialogFragment dialogFragment = new YourDialogFragment();
asyncTask.setDismissListener(dialogFragment);

@Override
protected void onPostExecute(Void result) {
    // 其他代码...
    if (dismissListener != null) {
        dismissListener.onDismissDialog();
    }
}
