OnActivityResult not getting called in Fragment where intent pass from adapter class

Question

So in my adapter class, I would like to allow user to capture image

 fun dispatchTakePictureIntent() {
        try {
            val captureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            (context as Activity).startActivityForResult(captureIntent, 1)
        } catch (e: ActivityNotFoundException) {
            e.printStackTrace()
        }
    }

    fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
        Log.d("MyAdapter", "onActivityResult")
    }

I want the onActivityResult in a fragment class get called, but it doesn't.

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
        val imageListAdapter : ImageListAdapter?=null
        imageListAdapter?.onActivityResult(requestCode, resultCode,data)
                if (requestCode == 1 && resultCode == Activity.RESULT_OK) 
                {
                    longToast("called")
                }else{
                    longToast("no")
                }
            }

There are no toast displayed. How to solve ?

I realize the onActivityResult works if I put in one of my Activity class, but I want to put at Fragment class !

Downvoters should explain why ! – Vilayet

check this #6148384 – Anguish

@NileshRathod if I put the onActivityResulty in one of the activity class, it works. But I want it call in fragment ! Is it because of this line ? (context as Activity) – Vilayet

@NileshRathod my startActivityForResult need to call in Adapter class – Vilayet

Why don't you move your dispatchTakePictureIntent() inside your activity and call startActivityForResult from fragment – Anguish

Possible duplicate of onActivityResult is not being called in Fragment – Anse

@Anse added super.onActivityResult but still no luck – Vilayet

Your problem is about the context and who calls startActivityForResult (which tells who will receive the result). It is explained in #6148384 and others. You just opened two duplicated questions IMO. – Anse

"added super.onActivityResult but still no luck" make sure to read the entire answer. First part was about super, the second part was not. – Anse

Answer 1

as nikita said you should call startActivityForResult from fragment if you want to get results in fragment.

I want to call startActivityForResult in adapter class, so I would need context as Activity Then create OnItemClick interface make your fragment implement it and pass it in a constructor to your Adapter. Then when a user clicks on an item call interface method

interface OnItemClickListener{
   onClick(item:T)
}

Foo: Fragment, OnItemClickListener{
...
    onClick(item:T){
        startActivityForResult...
    }
...
    initAdapter(){
        Adapter(listener=this,...)
    }

}

And in your adapter

...
itemView.setOnClickListener{
    listener.onClick(item)
}

thanks for your effort but it doesnt help. I have found a solution. Can you delete your answer so I can delete my post? – Vilayet

@Vilayet post your solution, it may help others – Isobelisocheim

Is it impossible to call startActivityForResult from adapter class and onActivityResult in fragment ??? – Vilayet

@Vilayet you can pass fragment (this) instead of context. and then call fragment.startActivityForResult(..) – Isobelisocheim

Answer 2

If you want fragment's onActivityResult() to be called, call startActivityForResult(intent, id) from fragment, not from activity (try pass fragment reference to adapter).

Also, make sure you haven't overridden activity's onActivityResult() or call super.onActivityResult() in activity.
