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";
    }
}

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;
        }

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;
}

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;
    }       
}

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

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;
}
