假设我想搜索“Starhub”，我不希望公司名称出现在搜索结果中。
当我输入“S”时，Jason Bourne 将出现在我的建议中，而不是“Jason bourne Starhub”
到目前为止，我可以完成名字和姓氏，但我不希望出现公司名称，我该如何改进？请帮忙。

您需要进行自己的定制ArrayAdapter<String>它将仅向 AutoCompleteTextView 提供您想要的信息。您可以将其作为当前文件中的内部类来执行此操作，也可以在其自己的外部文件中编写一个内部类。有关 ArrayAdapters 的文档将是您开始查找有关如何扩展此类并提供您正在寻找的功能的信息的好地方。看看here .
