[RK3288][Android7.1] 调试笔记 --- 设置第三方输入法为默认输入法

Platform: RK3288
OS: Android 7.1.2
Kernel: v4.4.143

需求：

设置第三方输入法为默认输入法

前提：

预装第三方输入法，参考

方法：

路径：/packages/SettingsProvider/res/values/defaults.xml 

config_default_input_method代表默认输入法

config_enabled_input_method代表内置的输入法，内置可以设置多个，用:隔开

<string name="config_enabled_input_method" translatable="false">com.sohu.inputmethod.sogou/.SogouIME:com.android.inputmethod.latin/.LatinIME</string>

代码形式为 “包名/类名，

“com.baidu.input_baidutv” 是百度输入法的包名“.ImeService”是百度输入法类名，这里是简略写法，类名名也可以写成全称“com.baidu.input_baidutv/com.baidu.input_baidutv.ImeService”

 其他知识点

1. 确定APK的包名和主类名

将APK直接拖动到Androidstudio，查看Androidmanifest

包名： package="com.baidu.input_baidutv">

类名：<service

            android:name="com.baidu.input_baidutv.ImeService"

2. 调试步骤：

#显示系统安装的输入法列表

adb shell ime list -s

#获取系统默认输入法

adb shell settings get secure default_input_method

#设置系统默认输入法

adb shell settings put secure default_input_method com.baidu.input_baidutv/com.baidu.input_baidutv.ImeService

#获取系统内置输入法

adb shell settings get secure enabled_input_method

#设置系统内置输入法

adb shell settings put secure enabled_input_method com.baidu.input_baidutv/com.baidu.input_baidutv.ImeService
