activity 标签总结1

activity:screenOrientation      限制横竖屏切换       默认是允许横竖屏切换的

   android:screenOrientation="unspecified"   默认值,由系统选择方向。所使用的策略,the choices made in specific contexts , may differ from device to device

   android:screenOrientation="portrait"    切换横竖屏时 限制此屏竖屏显示

   android:screenOrientation="landscape"切换横竖屏时 限制此屏横屏显示

   android:screenOrientation="user"  切向 用户当前所指定的方向 the user's current preffered orientation

   android:screenOrientation="behind"  切向 栈中当前activiry 的下方首个activity 所指向的方向 the same orientation as the acrivity that's

         immediately beneath 在...之下it in the activity stack

    android:screenOrientation=“sensor” 由物理传感器决定方向

    android:screenOrientation="nosensor" 方向 不再由物理传感器决定,所使用的策略 跟 unspecified 一样

 

activity:configChanges   当activity 的配置结构 在运行时 发生变化, activity默认 会关闭 并且 重新启动,但是申明这个属性会阻止activity 重启。activity会保持运行并且

  调用 onConfigrationChange() 方法

    注释 : 应尽量避免使用 这个属性 ,作为下下策, 更多处理运行时变化情况,请看  Handing Runtime Changes
