自动填充有两种
TextContentAdapter 只能用于Text文本框
ComboContentAdapter 只能用于Combo下拉框
AutoCompleteField和ContentProposalAdapter的区别
- AutoCompleteField用于自动完成，例如你输入“山”这个字的时候，可以快速选择输入“山东”或者“山西”。
- ContentProposalAdapter则用于内容建议，你输入“山西”的时候，按下快捷键或者特定字符，会给你“省”、“市”、“自治区”等建议
另外，还可以以给文本框加菜单的形式实现固定输入，在特定监听下，显示某些菜单，然后以此菜单的功能来输入内容。
