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();        
    }
}

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.

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，

使用getresource () .getConfiguration()。方向是正确的。

你只需要注意不同类型的景观，设备通常使用的景观和其他的。

还是不知道该怎么处理。

只是简单的两行代码

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
    // do something in landscape
} else {
    //do in potrait
}

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
}
