问题 So I'm working on my first real attempt at an Android app, just a simple scorekeeper for softball games. I've got it tallying scores, outs, etc, and right now it just displays "Home" and "Away." I'd like to give users the chance to enter in actual team names. To this effect, I added a custom AlertDialog that pops up with an EditText, so when you hit "OK" it'll update the Home/Away team name. The problem is I've been Googling this for most of the week and I've not found a single way to

使用AutoCompleteTextView实现邮箱地址补全

阅读更多关于使用AutoCompleteTextView实现邮箱地址补全

最近学习android时，用到AutoCompleteTextView，感觉挺有意思，于是模仿着网易邮箱地址补全的效果也实现了一个。 AutoCompleteTextView是一个具有自动补全功能的EditView，当用户输入数据后，AutoCompleteTextView就会将用户输入的数据与他自己的adapter中的数据对比，如果用户数据与adapter中的某条数据的开始部分完全匹配，那么adapter中的这条数据就会出现在下拉提示框中。例如：adapter中有3条数据“abc”，“hjk”，“abd”，而用户输入“ab”，那么下拉提示框中将会出现“abc”和“abd”。（AutoCompleteTextView默认在用户输入两个字符之后才提示，可以通过setThreshold(1)来将它设置为用户输入1个字符后就开始提示） AutoCompleteTextView在匹配用户输入数据时，会调用performFiltering方法，将用户数据传入，并调用adapter的filter来处理。因为当用户选中下拉列表中的某一项时， AutoCompleteTextView会使用该项对应的adapter中的数据来填充文本域，这与我们这边的需求不太相同，因为我们的adapter中只有类似于“@163.com”的email地址后缀
