아래와 같은 메세지로 런타임 에러가 발생했는데 전 제가 뭘 잘못한건지 모르겠어요.

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);
}

newslist.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"

         android:layout_width="wrap_content"
         android:layout_height="wrap_content">
    </ListView>
</LinearLayout>

text_newslist.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"

        android:id="@+id/newslist_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">    
    </TextView>
</LinearLayout>

제가 뭘 잘못한거죠?
