在config.xml中的<widget>下添加<preference name="orientation" value="portrait" />对我来说很有效。

(其他解决方案要么在我的设备上不起作用，要么在构建过程中被覆盖，要么在构建过程中给出了弃用错误。)

适用于任何Android版本

从XML

你可以在manifest.xml文件中为每个活动指定android:screenOrientation="portrait"。不能在应用程序标记上指定此选项。

从Java

另一个选择是通过编程来实现，例如在Activity基类中:

@Override
public void onCreate(Bundle savedInstanceState) {
  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

Android 4+ (API 14+)

最后一个选项是使用活动生命周期监听器，这只在Android 4.0 (API 14+)后可用。所有事情都发生在一个自定义Application类中:

@Override
public void onCreate() {
    super.onCreate();  
    registerActivityLifecycleCallbacks(new ActivityLifecycleAdapter() {
        @Override
        public void onActivityCreated(Activity a, Bundle savedInstanceState) {
            a.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }
    });
}

ActivityLifecycleAdapter只是一个您需要创建的助手类，它将是ActivityLifecycleCallbacks的一个空实现(因此当您只需要其中一个方法时，您不必重写该接口的每个方法)。

在kotlin——>

在你的Extends Application类中使用这个onCreate()…

registerActivityLifecycleCallbacks(object : ActivityLifecycleCallbacks {
        override fun onActivityCreated(p0: Activity, p1: Bundle?) {
            p0.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE;
        }

        override fun onActivityStarted(p0: Activity) {
        }

        override fun onActivityResumed(p0: Activity) {
        }

        override fun onActivityPaused(p0: Activity) {
        }

        override fun onActivityStopped(p0: Activity) {
        }

        override fun onActivitySaveInstanceState(p0: Activity, p1: Bundle) {
        }

        override fun onActivityDestroyed(p0: Activity) {
        }
    }

    )}

有两种方法。

添加android:screenOrientation="portrait"在你的manifest文件 相应的活动 添加 setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 在onCreate()方法中添加到您的活动

您可以为整个应用程序这样做，而不必使所有活动扩展一个公共基类。

诀窍是首先确保在项目中包含Application子类。在它的onCreate()中，当你的应用程序第一次启动时调用，你注册了一个ActivityLifecycleCallbacks对象(API级别14+)来接收活动生命周期事件的通知。

这让你有机会在应用程序中的任何活动启动(或停止，或恢复，或其他)时执行自己的代码。此时，您可以在新创建的活动上调用setRequestedOrientation()。

class MyApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();  

        // register to be informed of activities starting up
        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {

            @Override
            public void onActivityCreated(Activity activity, 
                                          Bundle savedInstanceState) {

                // new activity created; force its orientation to portrait
                activity.setRequestedOrientation(
                    ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

            }

            ....

        });

    }
}

来自Android开发者指南:

"orientation" The screen orientation has changed — the user has rotated the device. Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations. "screenSize" The current available screen size has changed. This represents a change in the currently available size, relative to the current aspect ratio, so will change when the user switches between landscape and portrait. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device). Added in API level 13.

所以，在AndroidManifest.xml文件中，我们可以放:

<activity
            android:name=".activities.role_activity.GeneralViewPagerActivity"
            android:label="@string/title_activity_general_view_pager"
            android:screenOrientation="portrait"
            android:configChanges="orientation|keyboardHidden|screenSize"
            >
        </activity>
