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。

2019年在API 28上测试，无论用户是否设置了纵向方向，与另一个过时的答案相比，使用最少的代码，以下代码提供了正确的方向:

/** @return The {@link Configuration#ORIENTATION_SQUARE}, {@link Configuration#ORIENTATION_PORTRAIT}, {@link Configuration#ORIENTATION_LANDSCAPE} constants based on the current phone screen pixel relations. */
private int getScreenOrientation()
{
    DisplayMetrics dm = context.getResources().getDisplayMetrics(); // Screen rotation effected

    if(dm.widthPixels == dm.heightPixels)
        return Configuration.ORIENTATION_SQUARE;
    else
        return dm.widthPixels < dm.heightPixels ? Configuration.ORIENTATION_PORTRAIT : Configuration.ORIENTATION_LANDSCAPE;
}

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。

It's also worth noting that nowadays, there's less good reason to check for explicit orientation with getResources().getConfiguration().orientation if you're doing so for layout reasons, as Multi-Window Support introduced in Android 7 / API 24+ could mess with your layouts quite a bit in either orientation. Better to consider using <ConstraintLayout>, and alternative layouts dependent on available width or height, along with other tricks for determining which layout is being used, e.g. the presence or not of certain Fragments being attached to your Activity.

Android SDK可以很好地告诉你:

getResources().getConfiguration().orientation

用这种方法，

    int orientation = getResources().getConfiguration().orientation;
    String Orintaion = "";
    switch (orientation)
    {
        case Configuration.ORIENTATION_UNDEFINED: Orintaion = "Undefined"; break;
        case Configuration.ORIENTATION_LANDSCAPE: Orintaion = "Landscrape"; break;
        case Configuration.ORIENTATION_PORTRAIT:  Orintaion = "Portrait"; break;
        default: Orintaion = "Square";break;
    }

在字符串中，你有方向
