You can simply override BaseActivity onActivityResult on fragment baseActivity.startActivityForResult . On BaseActivity add interface and override onActivityResult. private OnBaseActivityResult baseActivityResult; public static final int BASE_RESULT_RCODE = 111; public interface OnBaseActivityResult{ void onBaseActivityResult(int requestCode, int resultCode, Intent data); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(getBaseActivityResult() !=null && requestCode == BASE_RESULT_RCODE){ getBaseActivityResult().onBaseActivityResult(requestCode, resultCode, data); setBaseActivityResult(null); } On Fragment implements OnBaseActivityResult @Override public void onBaseActivityResult(int requestCode, int resultCode, Intent data) { Log.d("RQ","OnBaseActivityResult"); if (data != null) { Log.d("RQ","OnBaseActivityResult + Data"); Bundle arguments = data.getExtras(); } }

这个变通方法会奏效。

我的问题是与主机活动，我发现它与一个设置android:launchMode=“标准”，我删除它临时，它工作!

这是最受欢迎的问题之一。我们可以找到很多关于这个问题的帖子。但没有一个对我有用。

所以我用这个方法解决了这个问题。

让我们先来理解为什么会发生这种情况。

我们可以直接从Fragment调用startActivityForResult，但实际上背后的机制都是由Activity处理的。

一旦你从一个Fragment中调用startActivityForResult, requestCode将会被改变以附加Fragment的标识到代码中。这将使Activity能够在收到结果后跟踪发送此请求的人。

一旦Activity被导航回来，结果将被发送到Activity的onActivityResult和修改后的requestCode，它将被解码为原始的requestCode + Fragment的标识。之后，Activity会通过onActivityResult将ActivityResult发送给那个Fragment。一切都完成了。

问题是:

Activity只能将结果发送给直接附加到Activity的Fragment，而不能发送给嵌套的Fragment。这就是为什么嵌套片段的onActivityResult无论如何都不会被调用的原因。

解决方案:

1)通过以下代码开始你的片段的意图:

       /** Pass your fragment reference **/
       frag.startActivityForResult(intent, REQUEST_CODE); // REQUEST_CODE = 12345

2)现在在你的父活动覆盖**onActivityResult():**

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
    }

你必须在parent activity中调用它才能使它工作。

3)在你的片段调用中:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {

       }
}

就是这样。 有了这个解决方案，它可以应用于任何单个片段，无论它是否嵌套。是的，它也涵盖了所有的情况!此外，代码也很漂亮和干净。

我在使用ChildFragmentManager时有同样的问题。管理器不会将结果传递给嵌套片段，您必须在基本片段中手动执行此操作。

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    Fragment fragment = (Fragment) getChildFragmentManager().findFragmentByTag(childTag);
    if (fragment != null) {
        fragment.onActivityResult(requestCode, resultCode, intent);
    }
}

我想你调用了getActivity(). startactivityforresult(意图，111);。你应该调用startActivityForResult(intent,111);。
