当 Activity 从 Fragment 启动时未调用 onActivityResult() [英] onActivityResult() not called when Activity started from Fragment

问题描述

我在 Android 中从相册导入图片时遇到问题，因为从不调用 onActivityResult() 方法.

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

这是我写的代码(从片段而不是活动调用):

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 onActivityResult() 但它从未被触发:

And by the way, I have defined the onActivityResult() but it's never triggered:

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

知道这有什么问题吗?

谢谢！

推荐答案

要在片段中调用 onActivityResult()，您应该调用片段版本的 startActivityForResult()，不是活动的.所以在你的片段代码中，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);
