As has been commented in your question, I'm not sure EXACTLY what you're asking, but you can test whether the user originally disagreed to location permissions using shouldShowRequestPermissionRationale. 
Below is some expanded code based on the Requestion Permissions documentation that I use and that you may find helpful.  
    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
            && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        Log.d(TAG, "checkMyPermissions ( " + permissionRequestCode + ") : Permissions FAILED");
        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) {
            // Show an explanation to the user *asynchronously* -- don't block
            // this thread waiting for the user's response! After the user
            // sees the explanation, try again to request the permission.
            new AlertDialog.Builder(this)
                    .setMessage("In order to show data this app requires location permissions")
                    .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            ActivityCompat.requestPermissions(MainActivity.this,
                                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                                    permissionRequestCode);
                        }
                    })
                    .setNegativeButton(android.R.string.cancel, null)
                    .show();
        } else {
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                    permissionRequestCode);
        }
        return false;
    } else {
        Log.d(TAG, "checkMyPermissions ( " + permissionRequestCode + ") : Permissions Passed");
        return true;
    }
