Issue
I'm following this online tutorial to build a part of my app that will return a list of my contacts, but I've run in to a bit of an issue that doesn't seem to be mentioned anywhere in the tutorial.
This is in the class ContactsFragment
, which is not the main activity of the project but returns the fragment for the main activity to use.
The error is occurring here...
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mContactsList =
(ListView) getActivity().findViewById(R.layout.contacts_list_view); <--- here
//...
}
The error reads "expected resource of type id", which is strange because Android Studio's intellisense is suggesting contacts_list_view
to me when writing the code.
contacts_list_view.xml
is a file in the res/layout
directory that I have copied from the tutorial. Its contents is as below:
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
I'm pretty new to Android Studio and Android development in general, so there's a chance I'm missing something obvious. Feel free to point that out to me, or anything else that might fix my issue!
Thanks,
Mark
Solution
Change this line in the code:
(ListView) getActivity().findViewById(R.layout.contacts_list_view);
for (ListView) getActivity().findViewById(R.id.list);
And in the .xml file:
android:id="@android:id/list"
for android:id="@+id/list"
