2. 设置默认输入法

设置默认输入法首先在机器上安装相应的输入法并设置成默认，然后连接adb输入以下命令

$ adb shell settings get secure enabled_input_methods
com.android.inputmethod.latin/.LatinIME:com.iflytek.inputmethod.google/com.iflytek.inputmethod.FlyIME:com.google.android.inputmethod.pinyin/.PinyinIME
$ adb shell settings get secure default_input_method
com.iflytek.inputmethod.google/com.iflytek.inputmethod.FlyIME

获取启用的输入法和默认输入法,然后在SettingProvider里面添加如下代码
