这里的很多答案都建议在AndroidManifest.xml文件中使用“portrait”。这似乎是一个很好的解决方案-但正如文档中所指出的那样，您正在挑出可能只有横屏的设备。你还强迫某些设备(在横屏下工作得最好)进入竖屏，而没有得到正确的方向。

我的建议是用“nosensor”代替。这将使设备使用其默认的首选方向，不会阻止谷歌Play上的任何购买/下载，并将确保传感器不会破坏你的游戏(在我的情况下是NDK)。

在你声明你的活动的manifest文件中添加android:screenOrientation="portrait"。是这样的:

<activity 
    android:name=".yourActivity"
    ....
    android:screenOrientation="portrait" />

如果你想使用Java代码，试试:

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

在onCreate()中调用setContentView方法之前。

在manifest类中:

<activity android:name=".yourActivity"
    ....
    android:screenOrientation="portrait" />

或通过编程:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

注意:你应该在你的onCreate()活动的setContentView方法之前调用这个。

如何在一些视图中改变方向

不是锁定整个活动的方向，你可以使用这个类从你的任何视图中动态地锁定方向:

让你的视图成为景观

OrientationUtils.lockOrientationLandscape(mActivity);

将视图设置为竖屏

OrientationUtils.lockOrientationPortrait(mActivity);

解锁取向

OrientationUtils.unlockOrientation(mActivity);

        }

        if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_90) {
            if (orientation == Configuration.ORIENTATION_PORTRAIT) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {

            }

                activity.setRequestedOrientation(SCREEN_ORIENTATION_REVERSE_PORTRAIT);
            } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
                activity.setRequestedOrientation(SCREEN_ORIENTATION_REVERSE_LANDSCAPE);

        }
    }

    /** Unlocks the device window in user defined screen mode. */
    public static void unlockOrientation(Activity activity) {
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER);
    }

}

你所需要的就是AndroidManifest.xml中活动的以下属性:

android:configChanges="orientation"

那么，完整的活动节点:

<activity
    android:name="Activity1"
    android:icon="@drawable/icon"
    android:label="App Name"
    android:configChanges="orientation">

你应该在AndroidManifest.xml中修改android:screenOrientation="sensorPortrait
