安卓：180°90°旋转关闭，但启用轮换 [英] Android: Disable rotations by 90°, but enable rotations by 180°

问题描述

我想创建一个Android应用程序（一个片）应该只显示在横向例如，该应用程序应该忽略旋转90°，而是180°旋转支持

I would like to create an Android app (for a tablet) that should be only displayed in landscape orientation, e.g. the app should ignore rotations by 90°, but support rotations by 180°.

添加机器人：screenOrientation =山水，在清单导致应用程序忽略所有旋转，（即使是180°旋转），即通过180°旋转设备显示应用程序倒挂

Adding android:screenOrientation="landscape" in the manifest causes the app to ignore all rotations, (even the 180° rotations), i.e. rotating the device by 180° shows the application upside down.

如果没有安卓screenOrientation属性我的应用程序是正确的所有四个位置显示。旋转装置180°翻转的UI垂直RESP。水平。

Without the android:screenOrientation attribute my app is displayed "correctly" in all four positions. Rotation the device by 180° flips the UI vertically resp. horizontally.

在轮换将创建下列日志信​​息设备（也许这可以帮助？）：

When rotation the device the following log messages are created (maybe this helps?):

[...]: INFO/WindowManager(1290): Setting rotation to 1, animFlags=0
Rotation is a value between 0 and 3 representing the current orientation.

总结：是否有可能使一个应用程序来支持景观取向

Summarized: Is it possible to enable an app to support both landscape orientations?

推荐答案

新的<一个href="http://developer.android.com/intl/fr/reference/android/R.attr.html#screenOrientation">sensorLandscape屏幕方向显然是指用于此目的。

The new sensorLandscape screen orientation is apparently meant for this purpose.

例如，你可以这样做：

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

不幸的是，这仅仅是作为安卓2.3。目前，我正在寻找一种方式来实现这一目标的升级Froyo。

Unfortunately, this is only available as of Android 2.3. I'm currently looking for a way to achieve this on Froyo.
