Hi all,
I am encountering an exception in the onCreate method of an activity.
java.lang.RuntimeException: Your content must have a
ExpandableListView whose id attribute is 'android.R.id.list'
The onCreate method is as below.
public class TestActivity extends ExpandableListActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.tab1);
registerForContextMenu(getExpandableListView());
getData();
}
........................
The layout view XML is as below.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ExpandableListView
android:id="@+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
I've already changed the ID of the ExpandableListView to "list". But
it is not effective.
Any ideas on what's wrong? Thanks!
Thanks & Regards,
YCH
