I´m changing my application to use CursorLoader instead of startManagingCursor....

And I have one AutoCompleteTextView, SimpleCursorAdapter and in my setFilterQueryProvider implementation, in "runQuery" method I have

    mProdutoAdapter.setFilterQueryProvider(new FilterQueryProvider() {
        @Override
        public Cursor runQuery(CharSequence constraint) {

            Cursor cursor = mVendasDb.getProdutos(constraint.toString());
            startManagingCursor(cursor);
            return cursor;
        }
    });

How can I change this part to make it works with CursorLoader?

Should I discard setQueryFilterProvider and use TextWatcher in the AutocompleteTextView and then call getLoaderManager().restartLoader(0, bundleFilter, this)??? I have no idea how to proced!

bundleFilter would have the text came from textwatcher.

Is it ok using this aproach? Is it the best to do in this case?

这是一个很好的方法，根据 android 开发者网站：

重新启动加载程序：

要丢弃旧数据，请使用 restartLoader()。例如，当用户查询发生变化时，SearchView.OnQueryTextListener 的这个实现会重新启动加载程序。加载程序需要重新启动，以便它可以使用修改后的搜索过滤器来执行新查询：
