一,背景介绍

        Android 系统属性主要有两种:SettingsProvider 和 SystemProperties 。

二,SettingsProvider详解

2.1 关于Android"设置"里的一些属性可以直接通过settings命令直接查看或者设置adb shell 下 settings指令可以分别查看系统、全局、安全设置属性。

2.1.1 settings查看方法

adb shell settings list system
adb shell settings list global
adb shell settings list secure

2.1.2 属性的存储位置


/data/system/users/0/下的对应xml文件:

settings_global.xml

settings_secure.xml

settings_system.xml

2.1.3 settings方法

# get方法
adb shell settings get global bluetooth_on
# set方法
adb shell settings put global bluetooth_on 1
C:\Users\Administrator>adb shell
abc‏‎‎‏‎:/ $ su
abc‏‎‎‏‎:/ # settings list global | grep device
device_name=‎‏‎‎‎‎‎‏‎‏‏‏‎‎‎‎‎‏‎‎‏‎‎‎‏‎‏‏‏‏‏‏‏‏‏‏‏‎‏‎‏‏‎‏‏‎‎‏‎‏‎‏‎‏‎‎‎‏‎‎‏‎‎‎‏‎‎‏‏‏‎‏‎‏‎‎‏‎‏‎‏‎‏‏‏‏‏‏‎‏‏‏‏‎‏‎Android abc‏‎‎‏‎
device_provisioned=1
abc‏‎‎‏‎:/ #

2.1.4 源码相关

状态值进行存储:frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java

设置的成员定义:frameworks/base/core/java/android/provider/Settings.java

部分的默认值来源于:frameworks/base/packages/SettingsProvider/res/values/defaults.xml

settings代码位置在:frameworks/base/cmds/settings/settings

2.1.5 settings实例

#获取自动锁屏时间
adb shell settings list system | grep timeout                            
screen_off_timeout=300000
#设置自动锁屏时间
adb shell settings put system screen_off_timeout 2147483647
#全屏沉浸模式(包括状态栏和虚拟按键):
adb shell settings put global policy_control immersive.full=*
#沉浸状态栏:
adb shell settings put global policy_control immersive.status=*
#沉浸虚拟按键(隐藏后底部上划可以呼出):
adb shell settings put global policy_control immersive.navigation=*
#恢复正常模式(如果隐藏了状态栏或者虚拟按键但是又不想用了):
adb shell settings put global policy_control null

三,系统属性读取

3.1 在adb中进行属性读取和设置

3.1.1 Settings Provider设置和读取

//查看screen_off_timeout的值,可以使用下面的命令
$ adb shell settings get system screen_off_timeout
$ 60000 

这里属性值是严格区分大小写的(全部都是小写),不存在的值或者写错就获取到null。

//修改休眠时间
$ adb shell settings put system screen_off_timeout 120000 //120秒,2分钟

3.1.2、SystemProperties属性读取和设置

3.2 Android代码中进行属性读取和设置

3.2.1 Settings Provider设置和读取

Settings Provider是指通过如下方式设置的系统变量数据库:

//读取
Settings.System.getInt(Context.getContentResolver(), "xxx", 1);
Settings.System.getString(Context.getContentResolver(), "xxx", "1");
Settings.System.getLong(Context.getContentResolver(), "xxx", 1);
Settings.System.getFloat(Context.getContentResolver(), "xxx", 1);
//设置
Settings.System.putInt(Context.getContentResolver(), "xxx", 1);
Settings.System.putString(Context.getContentResolver(), "xxx", "1");
Settings.System.putLong(Context.getContentResolver(), "xxx", 1);
Settings.System.putFloat(Context.getContentResolver(), "xxx", 1);
xxx表示属性,比如:screen_off_timeout
