The need has recently been changed to a special,It 's estimated that some people have come across this disgusting demand.,The client actually needs to enterIPAddress,I feel a little ripped .,Customer InputIPAddress,hehe,anyway,No, it's not done.,didn't cut the manager's strength.,only the code..

The following start the subject , First run the effect , easy to watch



The input box above is written as a custom combo control,Easy to use,It's pretty easy to say .,The main combination of fourEditText,then JudgeEditTextInput Content,There is also the focus of the acquisition is more important,as I just learnedAndroidsoon,there might be a better way.,This is just a way of writing my own implementation.,the same way you can implement a phone number in this manner,bank card and other input methods

Paste the code for the custom combo control below :
