Android-片段内的RecyclerViewAdapter中的startActivityForResult（）

Question

I want to take a picture by pressing an item inside a RecyclerView . If I do ((MainActivity)context).startActivityForResult , onActivityResult in Activity will be called.. How to call it inside the Fragment holding the Adapter ?

I know I can just pass the fragment inside the adapter. But I'm concerned about the memory usage.

Answer 1

If you have a reference to the fragment in the adapter, you can use:

fragment.startActivityForResult(Intent intent, int requestCode);

Then in the fragment, you need the following:

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