android - onActivityResult ResultCode 始终为 0

Question

我总是用下面的代码得到 ResultCode = 0。
这是我处理setResult

的代码

  @Override
        public void onResponse(Call<ResponseBody> call, retrofit2.Response<ResponseBody> response) {
            Debug.i("Response Status Complete " + response.code());
            if (response.code() == 200) {
                Debug.i("Response Status Complete " + response);

                mSectionTopic.isComplete = 1;
                mSectionTopic.status = "completed";

                Intent intent = new Intent();
                intent.putExtra(Util.getIntentName("sectionTopic"), mSectionTopic);
                intent.putExtra(Util.getIntentName("challengeId"), "AIzaSyBkSGK9geQ4QbnvXcQQ_m2JScd7r89xnJs");
                intent.putExtra(Util.getIntentName("position"), mPosition);

                setResult(Activity.RESULT_OK, intent);
                finish();

            } else {
                showError(getString(R.string.text_post_question_failed));
            }

但是如果代码 onBackPressed(); resultcode 工作正常。

我的代码有什么问题？

这是我的onActivityResult()

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQ_CODE && resultCode == Activity.RESULT_OK) {
        if (data == null) return;
        int position = data.getIntExtra(Util.getIntentName("position"), 0);
        mAdapter.setComplete(position);
        mAdapter.notifyDataSetChanged();

    }
}

您需要正确实现 startActivityForResult() 和 onActivityResult()。按照此处的说明进行操作 - Transfer data between two activities
