数据返回错误onActivityForResult（）

Question

我之前没有遇到任何问题，所以我可能错过了一些愚蠢的事情。

我正在尝试启动一个辅助活动，在我的数据库中创建一个新的所有者并返回所有者的ID。

在我的第一个活动中，我正在呼叫第二个活动：

Intent new_owner = new Intent(this, AddOwnerActivity.class);
startActivityForResult(new_owner, REQUEST_NEW_OWNER, null);
overridePendingTransition(R.anim.slide_in_bottom, R.anim.abc_fade_out);

然后在我的第二个Activity中我设置结果如下：

 Intent data = getIntent();
 Log.v("OWNER", "DATA sending: "+new_owner.getId()); // this logs a number like 13
 data.putExtra("owner_id", new_owner.getId() );
 setResult(RESULT_OK,data);
 onBackPressed();//this calls finish();

最后在我的第一个Activity中，我的onActivityResult看起来像这样：

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode == REQUEST_NEW_OWNER && resultCode == RESULT_OK && data!=null){
            Bundle bundle = data.getExtras();
            setUpOwnerSelector();
            Log.v("OWNER", "DATA received: " + bundle.getInt("owner_id"));//this is ALWAYS LOGGING 0
            selectOwnerWithId(bundle.getInt("owner_id"));
        }
    }

我可以看到我的新所有者是在数据库中成功创建的，而在我的辅助活动中，当我设置结果时，它正在记录正确的ID，但我的第一个活动是始终记录0作为额外的...

我必须要错过一些小东西......第二双眼睛会受到赞赏
