NOTE When we add a horizontalGap in pixels, this interferes with keyWidth in percentages adding up to 100%

一些技巧：
阅读本教程：Creating an Input Method
克隆这个回购：LatinIME
关于你的问题：
一个inputMethod基本上是一个Android
Service，所以是的，你可以做HTTP和你可以在_837394中做的所有事情 .您可以从
InputMethod打开Activities和对话框 . 再一次，它只是一个Service.我一直在开发一个IME，所以再问一下你是否遇到了问题 .
为自己的EditText创建自定义键盘
Download Entire Code
在这篇文章我创建简单的键盘，其中包含一些特殊的键，如（法国键），它支持大写字母和小写字母和数字键和一些符号 .
一个好的起点是sample application provided on the developer docs .
指南只是让它尽可能可用 . 看看市场上的其他产品，看看你的目标是什么
是的，服务可以做大多数事情，包括互联网;只要您要求这些权限
如果在键盘上做某些事情遇到问题，你可以打开活动并做任何你喜欢的事情 . 例如，HTC的键盘有一个用于打开设置活动的按钮，另一个用于打开一个用于更改语言的对话框 .
看看其他IME，看看你应该瞄准什么 . 有些（像官方的）是开源的 .
首先，您应该定义.xml文件并在其中创建键盘UI：
在此示例中，您有4行，每行有3个键 . 你也可以在你想要的每个键上放一个图标 .
然后，您应该在活动UI中添加xml标记，如下所示：
同样在.java活动文件中，您应该定义键盘并将其分配给EditText：
此代码将inputSearch（它是EditText）作为键盘 .
