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，

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

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;
}

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
        }

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;
        }

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;
    }       
}
