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

大多数答案已经发布了一段时间，其中一些使用了现在已弃用的方法和常量。

我已经更新了Jarek的代码，不再使用这些方法和常量:

protected int getScreenOrientation()
{
    Display getOrient = getWindowManager().getDefaultDisplay();
    Point size = new Point();

    getOrient.getSize(size);

    int orientation;
    if (size.x < size.y)
    {
        orientation = Configuration.ORIENTATION_PORTRAIT;
    }
    else
    {
        orientation = Configuration.ORIENTATION_LANDSCAPE;
    }
    return orientation;
}

注意配置模式。不再支持ORIENTATION_SQUARE。

与建议使用getResources().getConfiguration().orientation的方法相比，我发现这个方法在我测试过的所有设备上都是可靠的

有很多方法可以做到这一点，这段代码适合我

 if (this.getWindow().getWindowManager().getDefaultDisplay()
                .getOrientation() == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) {
             // portrait mode
} else if (this.getWindow().getWindowManager().getDefaultDisplay()
                .getOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
                      // landscape
        }

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.

简单易行:)

制作2个xml布局(即纵向和横向) 在java文件中，写入: private int intOrientation; 在onCreate方法和setContentView之前写入: intOrientation = getResources().getConfiguration().orientation; if (intOrientation == Configuration.ORIENTATION_PORTRAIT) setContentView (R.layout.activity_main); 其他的 setContentView (R.layout.layout_land);//我测试了它，它工作正常。

在运行时检查屏幕方向。

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();

    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();        
    }
}
