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。

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;
}

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)

希望能有所帮助，

还有一种方法:

public int getOrientation()
{
    if(getResources().getDisplayMetrics().widthPixels>getResources().getDisplayMetrics().heightPixels)
    { 
        Toast t = Toast.makeText(this,"LANDSCAPE",Toast.LENGTH_SHORT);
        t.show();
        return 1;
    }
    else
    {
        Toast t = Toast.makeText(this,"PORTRAIT",Toast.LENGTH_SHORT);
        t.show();
        return 2;
    }       
}

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.

我认为这个解决方法很简单

if (context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
  user_todat_latout = true;
} else {
  user_todat_latout = false;
}
