我认为这段代码可以在方向改变生效后工作

Display getOrient = getWindowManager().getDefaultDisplay();

int orientation = getOrient.getOrientation();

覆盖的活动。onConfigurationChanged(Configuration newConfig)函数，如果你想在调用setContentView之前得到关于新方向的通知，请使用newConfig,orientation。

当前配置，用于确定检索哪些资源，可以从resources的configuration对象中获得:

getResources().getConfiguration().orientation;

你可以通过查看它的值来检查方向:

int orientation = getResources().getConfiguration().orientation;
if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
    // In landscape
} else {
    // In portrait
}

更多信息可以在Android开发者中找到。

这样就覆盖了所有的手机，如oneplus3

public static boolean isScreenOrientationPortrait(Context context) {
    return context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT;
}

正确代码如下:

public static int getRotation(Context context) {
    final int rotation = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getOrientation();

    if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) {
        return Configuration.ORIENTATION_PORTRAIT;
    }

    if (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270) {
        return Configuration.ORIENTATION_LANDSCAPE;
    }

    return -1;
}

你可以使用这个(基于这里):

public static boolean isPortrait(Activity activity) {
    final int currentOrientation = getCurrentOrientation(activity);
    return currentOrientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT || currentOrientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
}

public static int getCurrentOrientation(Activity activity) {
    //code based on https://www.captechconsulting.com/blog/eric-miles/programmatically-locking-android-screen-orientation
    final Display display = activity.getWindowManager().getDefaultDisplay();
    final int rotation = display.getRotation();
    final Point size = new Point();
    display.getSize(size);
    int result;
    if (rotation == Surface.ROTATION_0
            || rotation == Surface.ROTATION_180) {
        // if rotation is 0 or 180 and width is greater than height, we have
        // a tablet
        if (size.x > size.y) {
            if (rotation == Surface.ROTATION_0) {
                result = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
            } else {
                result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE;
            }
        } else {
            // we have a phone
            if (rotation == Surface.ROTATION_0) {
                result = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
            } else {
                result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
            }
        }
    } else {
        // if rotation is 90 or 270 and width is greater than height, we
        // have a phone
        if (size.x > size.y) {
            if (rotation == Surface.ROTATION_90) {
                result = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
            } else {
                result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE;
            }
        } else {
            // we have a tablet
            if (rotation == Surface.ROTATION_90) {
                result = ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
            } else {
                result = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
            }
        }
    }
    return result;
}

指定手机当前方向的完整方法:

public String getRotation(Context context) {
    final int rotation = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getOrientation();
    switch (rotation) {
        case Surface.ROTATION_0:
            return "portrait";
        case Surface.ROTATION_90:
            return "landscape";
        case Surface.ROTATION_180:
            return "reverse portrait";
        default:
            return "reverse landscape";
    }
}

下面是hackbod和Martijn推荐的如何获得屏幕方向的代码片段演示:

改变时触发

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
        int nCurrentOrientation = _getScreenOrientation();
    _doSomeThingWhenChangeOrientation(nCurrentOrientation);
}

将当前方向设置为hackbod

private int _getScreenOrientation(){    
    return getResources().getConfiguration().orientation;
}

还有其他方法可以获得当前屏幕方向，参照Martijn方案:

private int _getScreenOrientation(){
        Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
        return display.getOrientation();
}

★注意: 我试过这两种实现，但在RealDevice (NexusOne SDK 2.3) Orientation上，它返回了错误的方向。

★所以我推荐使用解决方案来获得屏幕定位，有更多的优势:清楚，简单，工作就像一个魅力。

★仔细检查方向回归，以确保符合我们的预期(可能有限制取决于物理设备规格)
