onRequestPermissionsResult not being called in fragment if defined in both fragment and activity

by

I have a fragment in which I have recyclerview and setting data in this recyclerview using recyclerview adapter.

Now, I am having a button in the adapter’s list item clicking on which I need to check the READ_EXTERNAL_STORAGE permission in android for new permission model in android.

I have created a new function in this adapter’s fragment to check if permission is granted or not and request for permission if not granted already.

I have passed MyFragment.this as a parameter in the adapter and calling the fragment’s method on the button click in the adapter.

I have used the below code to call requestPermission in fragment.

if(ContextCompat.checkSelfPermission(mContext, Manifest.permission.READ_EXTERNAL_STORAGE)
            != PackageManager.PERMISSION_GRANTED){
       requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                ConstantVariables.READ_EXTERNAL_STORAGE);
    }

I have overridden the onRequestPermissionsResult method in fragment by using the below code:

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case ConstantVariables.READ_EXTERNAL_STORAGE:
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, proceed to the normal flow.
                startImageUploading();
            } else {}

But it is not getting called, instead of this Activity’s onRequestPermissionsResult method is getting called.

I have defined the same onRequestPermissionsResult method in fragment’s parent activity also and it is getting called.

I can not remove the activity’s onRequestPermissionsResult method but want to call fragment’s onRequestPermissionsResult method when I request permission from fragment.
How can I do this? Am I doing something wrong here, please help me if anyone have idea here.
