关于android删除语音搜索功能的基本操作方法

       最近在调试android 4.1系统的平板,发现在进行录音操作的时候,系统总是频繁的自动弹出语音搜索对话框,而且需要连续关闭好几次才能把它关闭掉,也不知道这到底是怎么回事,估计可能是系统还不太稳定的缘故吧。没办法,最后就想到干脆把语音搜索的程序删除算了,反正这个语音搜索也是不太好使。好了,下面来说一说这个具体的操作流程,

1.删除系统自带的语音搜索程序

.      android 源代码里好像没有语音搜索的源代码,只找到它的apk文件,而且语音搜素与谷歌搜素是连在一起的,要删除语音搜索的话,还必须同时删除了谷歌搜素程序,需要删除的apk文件有device/.../googleapps/app/目录下的velvet.apk以及VoiceSearchStub.apk,同时还需要删除out目录下对应的APK文件,然后就可以编译生成固件,对机器进行升级了。

2.删除浏览器自带的语音搜索功能

       要删除浏览器网址输入框右边的语音搜素按钮(麦克风图标),只需在packages/apps/Browser/src/com/android/browser/NavigationBarTablet.java文件里注释掉下面这行代码应该就行了:
       //mVoiceButton.setVisibility(View.VISIBLE);
3.经过第一步操作后,发现在窗口小部件中,长按住搜素控件,概率性弹出搜索出错对话框,而且点击搜索控件中的文字区域,不能进入搜索程序。

暂时就说到这了,后续有其他地方的修改再进行补充,这方面网上的资料也比较少,本人也走了些弯路,说到底还是比较简单的。
