SearchView没有执行它的功能，如何过滤这个自定义适配器

Question

我已经创建了一个自定义适配器扩展ArrayAdapter包含Listview与两个TextView在单行。我在ActionBar上有SearchView。在onQueryTextChange(字符串s)我已经尝试了一些方法，我发现，工作，但结果是不正确的，最后我只有第一行从ListView。如何使SearchView正确工作?一切正常。此应用程序适用于minSdkVersion="9"及以上。任何建议都可以。问候。

来自http://developer.android.com/:

一个由任意数组支持的具体BaseAdapter对象。默认情况下，该类期望提供的资源id引用单个TextView。如果你想用一个更复杂的布局时，使用也接受字段id的构造函数。这个字段id应该在更大的布局资源中引用TextView。

你有两个TextView，构造函数类是这样的:

ArrayAdapter(Context Context, int resource, int textViewResourceId)
