我正在开发一个Android应用程序，其中包含一个导航抽屉活动。这反过来包含两个选项卡“Alabanzas”和“Tema”，两者都可以从侧面菜单访问。 “Alabanzas”选项卡是一个片段，其中包含一个包含ListView的自定义ArrayAdapter。 在ActionBar中为SearchView中的“Alabanzas”中的搜索放置一个SearchView元素，但是我无法将搜索与ListView的元素链接起来 我的课程是以下......
使用导航抽屉的类MainActivity
onCreateOptionsMenu方法onChiteTextChange方法中的错误生成miadaptador.getFilter().Filter(s);，因为该适配器与具有搜索方法的Adapter类中安装的适配器不同

如果有人可以帮我在片段“Alabanzas”的listView中执行搜索，任何想法都会很受欢迎 谢谢
