onActivityResult 中的请求代码错误 [英] Wrong requestCode in onActivityResult

问题描述

我正在从我的 Fragment 开始一个新的活动

I'm starting a new Activity from my Fragment with

startActivityForResult(intent, 1);

并希望在 Fragment 的父 Activity 中处理结果:

and want to handle the result in the Fragment's parent Activity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult, requestCode: " + requestCode + ", resultCode: " + resultCode);
    if (requestCode == 1) {
        // bla bla bla
    }
}

问题是我从来没有收到我刚刚发布到 startActivityForResult() 的 requestCode.

The problem is that I never got the requestCode I've just posted to startActivityForResult().

我得到了类似 0x40001、0x20001 等的东西，并设置了一个随机的较高位.文档对此没有任何说明.有什么想法吗?

I got something like 0x40001, 0x20001 etc. with a random higher bit set. The docs don't say anything about this. Any ideas?

推荐答案

您正在从您的 Fragment 调用 startActivityForResult().执行此操作时，requestCode 将被拥有 Fragment 的 Activity 更改.

You are calling startActivityForResult() from your Fragment. When you do this, the requestCode is changed by the Activity that owns the Fragment.

如果你想在你的活动中获得正确的resultCode，试试这个:

If you want to get the correct resultCode in your activity try this:

变化:

startActivityForResult(intent, 1);

致:

getActivity().startActivityForResult(intent, 1);
