将结果(可序列化的类)从DialogFragment传递到片段

public interface OnResultListener {
    void onResult(Serializable result);
}

private OnResultListener onResultListener;

public void setOnResultListener(OnResultListener listener) {
    this.onResultListener = listener;
}

if (onResultListener != null) {
    onResultListener.onResult(result);
}

public class MyFragment extends Fragment implements OnResultListener {
    // ...

    @Override
    public void onResult(Serializable result) {
        // 处理传递的结果
    }
}

private void showDialogFragment() {
    MyDialogFragment dialogFragment = new MyDialogFragment();
    dialogFragment.setOnResultListener(this);
    dialogFragment.show(getFragmentManager(), "dialog");
}
