修改Android系统设置调用输入法（在线等）

[huanhuanfu]

根据需求，我们需要自己改写一个输入法设置，也就是安装后输入法后，可以选择新安装的输入法进行使用，但我改源码改好了之后，不知为什么，怎么都设置不进去，勾选后长按编辑框，勾选过的输入法调不出来，请各位高手帮小弟看看！


我已经找了很长时间了，但没有发现真正导致问题的原因，不知不否是因为我那里改的有问题。。
反正我的需求是一定要用Activity来实现的。。现在就差勾选的时候能调用出输入法，和不勾选的时候取消输入法就可以了
模拟器里面有效果，在“语言和键盘设置”里面
如果有朋友有空可以加我QQ一起研究一下：252339447
谁能帮我分析分析呀！！！！问题解决后可以多给分呀！！
谢谢大家啦！！！！

下面是我改过的代码：改过了之后编译就不能调用出输入法了
