                    Intent intent = new Intent(v.getContext(),player.class);
                    intent.putExtra("url",url);
                    v.getContext().startActivity(intent);
                }
            }
        });

        }
    }
}

Answer 1

If you look at the docs you'll see that Resources.getSystem().getStrings will provide you with system wide strings, not the ones in your application (strings.xml).

Replace the following line

String url = Resources.getSystem().getString(R.string.song);

with the following.

String url = v.getContext().getResources().getString(R.string.song);

Answer 2

You can also use context of TextView inside apply method from Kotlin.

Kotlin:

textView.apply {
    context.resources.getString(R.string.your_string)
}
