Clickable URL in Android-Studio TextView does not work - android-studio

Question

My Link looks like a link (itś color is blue) but when I click, nothing happens. Do you have any ideas? I use an external string where i want to put in the clickable URL.
Here is my xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/anthrazit">
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/textinfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:textColor="#color/lightwhite"
android:text="#string/info"
android:linksClickable="true"/>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
My java:
public class info extends MainActivity implements View.OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info);
final TextView infoTextView = (TextView) findViewById(R.id.textinfo);
infoTextView.setMovementMethod(LinkMovementMethod.getInstance());
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode ==
KeyEvent.KEYCODE_BACK) {
intent = new Intent(info.this, MainActivity.class);
startActivity(intent);
finish();
}
return false;
}
}
And my string. I found the code online, but in my Version it does not work :-( :
<string name="info">
