[Android] Activity configChanges属性

通过设置这个configChanges属性，可以使Activity捕捉设备状态变化，以下是可以被识别的内容。

设置方法：在manifest.xml中，将下列字段用“|”符号分隔开，例如：“locale|orientation”。

Value	Description
“mcc“	The IMSI mobile country code (MCC) has changed — that is, a SIM hasbeen detected and updated the MCC. 移动国家号码，由三位数字组成，每个国家都有自己独立的MCC，可以识别手机用户所属国家。
“mnc“	The IMSI mobile network code (MNC) has changed — that is, a SIM hasbeen detected and updated the MNC. 移动网号，在一个国家或者地区中，用于区分手机用户的服务商。
“locale“	The locale has changed — for example, the user has selected a new language that text should be displayed in. 用户所在地区发生变化。
“touchscreen“	The touchscreen has changed. (This should never normally happen.)
“keyboard“	The keyboard type has changed — for example, the user has plugged in an external keyboard. 键盘模式发生变化，例如：用户接入外部键盘输入。
“keyboardHidden“	The keyboard accessibility has changed — for example, the user has slid the keyboard out to expose it. 用户打开手机硬件键盘
“navigation“	The navigation type has changed. (This should never normally happen.)
“orientation“	The screen orientation has changed — that is, the user has rotated the device. 设备旋转，横向显示和竖向显示模式切换。
“fontScale“	The font scaling factor has changed — that is, the user has selected a new global font size. 全局字体大小缩放发生改变

通过一个例子介绍这个属性的用法： 首先需要修改项目的manifest:

在Activity中添加了
android:configChanges属性，目的是当所指定属性发生改变时，会调用到 onConfigurationChanged()函数。
