错误的requestCode从另一个活动返回了onActivityResult [英] Wrong requestCode returned onActivityResult from another Activity

问题描述

我有一个 Activity ，它调用了另一个 Activity ，又调用了其他 Activity .我发送到最后的 Activity 以获得结果，然后将结果发送回第一拳头 Activity .

I have an Activity that calls another Activity, that calls some other Activities. I send to the last Activity to get a result, and then i send back the result to the fist Activity.

流量真像

A -> B -> C -> D -> C -> B -> A

从 A 到 D 的流程由 startActivityForResult 组成，从 D 到的流程组成> A 由 onActivityResult 组成.

With the flow from A to D is made of startActivityForResult and the flow from D to A is made of onActivityResult.

从 D 到 B ， requestCode 始终相同(我决定的那个)，但是从 B 变成 A ，它突然从我的值变成了随机值(在这种情况下为196614).

From D to B the requestCode is always the same (the one I decided), but from B to A it suddenly change from my value to a random value (in this particular case 196614).

这是我用来从 activity A 调用 activity B 的代码:

This is the code I use to call the activity B from activity A:

filterByCatalogue.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), CatalogueContainerActivity.class);
            startActivityForResult(intent, Defines.FILTER_BY_CATALOGUE);
        }
    });

(使用 filterByCatalogue 作为 FrameLayout )

这是我用来调用活动A 的代码:

This is the code I use to call back the activity A:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == Defines.FILTER_BY_CATALOGUE) {
            if (resultCode == RESULT_OK) {
                Intent intent = new Intent();
                intent.putExtra("article", data.getStringExtra("article"));
                setResult(RESULT_OK, intent);
                finish();
            }
        }
    }

我已经搜索了很多，但是找不到错误的地方....

I've searched a lot but I can't find where I go wrong....

推荐答案

只需替换

startActivityForResult(intent, Defines.FILTER_BY_CATALOGUE);

使用

getActivity().startActivityForResult(intent, Defines.FILTER_BY_CATALOGUE);

它肯定会工作.:)
