Cursor cursor = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder); cursor.registerContentObserver(new ContentObserver(new Handler()) { @Override public void onChange(boolean selfChange) { super.onChange(selfChange); // Handle data change here } });In this example, the `Cursor` object is obtained through a query to a content provider using the `getContentResolver()` method. The `registerContentObserver()` method is then called on the `Cursor`, passing in a new `ContentObserver` object that defines how to respond to changes in the data. The `onChange()` method of the `ContentObserver` is overridden to handle the data change. The `android.database.Cursor.registerContentObserver` method is part of the `android.database` package library.
