int ot = getResources().getConfiguration().orientation;
switch(ot)
        {

        case  Configuration.ORIENTATION_LANDSCAPE:

            Log.d("my orient" ,"ORIENTATION_LANDSCAPE");
        break;
        case Configuration.ORIENTATION_PORTRAIT:
            Log.d("my orient" ,"ORIENTATION_PORTRAIT");
            break;

        case Configuration.ORIENTATION_SQUARE:
            Log.d("my orient" ,"ORIENTATION_SQUARE");
            break;
        case Configuration.ORIENTATION_UNDEFINED:
            Log.d("my orient" ,"ORIENTATION_UNDEFINED");
            break;
            default:
            Log.d("my orient", "default val");
            break;
        }

如果你使用getResources(). getconfiguration()。在某些设备上，你会得到错误的方向。我们最初在http://apphance.com中使用了这种方法。由于Apphance的远程记录，我们可以在不同的设备上看到它，我们看到碎片在这里发挥了作用。 我看到过一些奇怪的例子:比如HTC Desire HD上的竖屏和方形交替使用(?!)

CONDITION[17:37:10.345] screen: rotation: 270 orientation: square
CONDITION[17:37:12.774] screen: rotation: 0 orientation: portrait
CONDITION[17:37:15.898] screen: rotation: 90
CONDITION[17:37:21.451] screen: rotation: 0
CONDITION[17:38:42.120] screen: rotation: 270 orientation: square

或者完全不改变方向:

CONDITION[11:34:41.134] screen: rotation: 0
CONDITION[11:35:04.533] screen: rotation: 90
CONDITION[11:35:06.312] screen: rotation: 0
CONDITION[11:35:07.938] screen: rotation: 90
CONDITION[11:35:09.336] screen: rotation: 0

另一方面，width()和height()总是正确的(它被窗口管理器使用，所以它最好是)。我认为最好的方法是总是进行宽度/高度检查。如果你想一下，这正是你想要的——知道宽度是否小于高度(纵向)，相反的(横向)，或者它们是否相同(正方形)。

然后就变成了这段简单的代码:

public int getScreenOrientation()
{
    Display getOrient = getWindowManager().getDefaultDisplay();
    int orientation = Configuration.ORIENTATION_UNDEFINED;
    if(getOrient.getWidth()==getOrient.getHeight()){
        orientation = Configuration.ORIENTATION_SQUARE;
    } else{ 
        if(getOrient.getWidth() < getOrient.getHeight()){
            orientation = Configuration.ORIENTATION_PORTRAIT;
        }else { 
             orientation = Configuration.ORIENTATION_LANDSCAPE;
        }
    }
    return orientation;
}

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";
    }
}

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;
}

老帖子我知道。不管方向是什么或者被交换了等等。我设计了这个功能，用来将设备设置在正确的方向上，而不需要知道肖像和景观特征是如何在设备上组织的。

   private void initActivityScreenOrientPortrait()
    {
        // Avoid screen rotations (use the manifests android:screenOrientation setting)
        // Set this to nosensor or potrait

        // Set window fullscreen
        this.activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        DisplayMetrics metrics = new DisplayMetrics();
        this.activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

         // Test if it is VISUAL in portrait mode by simply checking it's size
        boolean bIsVisualPortrait = ( metrics.heightPixels >= metrics.widthPixels ); 

        if( !bIsVisualPortrait )
        { 
            // Swap the orientation to match the VISUAL portrait mode
            if( this.activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT )
             { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); }
            else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ); }
        }
        else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); }

    }

效果好极了!

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;
}
