When you setSelected true to your textview at that time textview is not in a position to perform command so you can do it inside view.post so when it is active it will perform the operation.

Try this code inside your button

btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            tv.setVisibility(View.VISIBLE);
            tv.post(new Runnable() {
                @Override
                public void run() {
                    tv.setSelected(true);
                }
            });
        }
    });
