的onActivityResult（）时，从活动开始片段不叫 [英] onActivityResult() not called when Activity started from Fragment

问题描述

我从相册中导入Android的图片的问题，因为的onActivityResult（）方法不会被调用。

I have an issue with importing a picture from the Album in Android, because the onActivityResult() method is never called.

这是code，我写（从片段而不是所谓的活动）：

This is the code that I wrote (called from a fragment not an activity):

Intent galleryIntent = new Intent(Intent.ACTION_PICK,  android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
getActivity().startActivityForResult(galleryIntent, PICK_IMAGE);

顺便说一下，我已经定义了的onActivityResult（），但它从来没有触发：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult"); // not printed
}

任何想法有什么错呢？

Any idea what's wrong with this?

谢谢！

推荐答案

要具有的onActivityResult（）堪称片段，你应该叫<$ C的片段的版本$ C> startActivityForResult（），而不是活动的。因此，在您片段的code，替换

To have onActivityResult() called in the fragment, you should call the fragment's version of startActivityForResult(), not the activity's. So in your fragment's code, replace

getActivity().startActivityForResult(galleryIntent, PICK_IMAGE);

与

startActivityForResult(galleryIntent, PICK_IMAGE);
