如何开发一个Android手机短信查看？ [英] How to develop an android SMS View?

问题描述

我

怎样才能做到这一点，你还能说的这个观点？

I want to develop a view in android that is similar to the compose SMS view. I am not really familiar with all android view elements.

It is obvious that this view uses some textfields. But I want to know what layouts are in use. E.g. when the user enters some text in the message field the Grey field expands.

How can I achieve this and what else can you say about this view?
