How to startActivityForResult from Adapter to get result back to Fragment

Question

I have several Fragments with custom ListViews. They use my custom ListAdapter, in which i handle clicks on list's elements. I need to start another activity from this OnClickListener and get some information back to Fragment. i try to use

Intent intent=new Intent(context, DataFillerActivity.class);  
((Activity) context).startActivityForResult(intent, 3);

but DataFillerActivity returns result to MainActivity, not to Fragment. so what is the best way to solve this problem ? thanks

Answer 1

Make onActivityResult method in Main Activity like this

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        //super.onActivityResult(requestCode, resultCode, data);
        // Check if image is captured successfully

        super.onActivityResult(requestCode, resultCode, data);
        for (Fragment fragment : getSupportFragmentManager().getFragments()) {
            fragment.onActivityResult(requestCode, resultCode, data);
        }
    }

It will pass the result code to its child fragment.

As Steve writes, a fragment should be modular. However, this means that the communication should not go through any activity but stay within the fragment.

To solve this, make sure your ListAdapter has a reference to the fragment and use fragment.startActivityForResult(). Then the result will come back to the fragment's onActivityResult().
