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();        
    }
}

我认为这个解决方案很容易检验的是景观

 public static boolean isLandscape(Context context) {
    final int rotation = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getRotation();
    
    if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) {
        return false;
    }

    return rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270;
}

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。

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。

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。

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.
