Courses Plus Student 1,777 PointsStuck on getting URL
Trying to get the correct syntax for this code challenge: At the bottom, can't seem to get the proper URL from the mUrls array.
Can someone help with this?
import android.os.Bundle; import android.widget.ArrayAdapter; import android.view.View; import android.view.ListView; import android.content.Intent; import android.net.Uri;
public class CustomListActivity extends ListActivity {
protected String[] mUrls = { "http://www.teamtreehouse.com", "http://developer.android.com", "http://www.github.com" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom_list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mUrls);
setListAdapter(adapter);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// Add code here!
super.onListItemClick(l, v, position, id);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(mUrls));
startActivity(intent);
}
}

You should use intent.setData(Uri.parse(mUrls[position]));

Courses Plus Student 1,777 PointsThank you Daniel!
That was the problem.
Maybe one day I'll get it!

18,106 PointsJust keep at it! I would recommend reading up on array's if you get a moment though as they do crop up all the time and are extremely useful so it is a good idea to have a background knowledge which unfortunately these tutorials only touch on.

Courses Plus Student 1,777 PointsWhen I get this tutorial done, I will indeed go back and read up on some of the functions we went over.
