There was a runtime error with the following message, but I don't know what I did wrong.
java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.newslist);
mDbHelper.open();
fillData();
}
private void fillData() {
Bundle extras = getIntent().getExtras();
long catID = extras.getLong("cat_id");
Cursor c = mDbHelper.fetchNews(catID);
startManagingCursor(c);
String[] from = new String[] { DBHelper.KEY_TITLE };
int[] to = new int[] { R.id.newslist_text };
SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.text_newslist, c, from, to);
setListAdapter(notes);
}

What did I do wrong?
android
<ListView android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
In the list view, give android:id as @android:id/list like that. You have to do that when you use the list activity.
