Android 在代码中设置屏幕名称

我正在使用Google Analytics for Android，我创建的跟踪器如下：

    GoogleAnalytics analytics = GoogleAnalytics.getInstance(context);
    tracker = analytics.newTracker(context.getString(R.string.ga_tracking_id));
    tracker.enableAutoActivityTracking(true);

<!-- The screen names that will appear in reports -->
<screenName name="com.mycompany.MyActivity">MyActivity Screen Name</screenName>

public class MyApp extends Application {
    private final String TRACKER_ID = "UA-12345678-1";

    private static GoogleAnalytics analytics;
    private static Tracker tracker;

    public static GoogleAnalytics analytics() {
        return analytics;
    }

    public static Tracker tracker() {
        return tracker;
    }

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

        analytics = GoogleAnalytics.getInstance(this);
        // analytics.getLogger().setLogLevel(Logger.LogLevel.VERBOSE);
        tracker = analytics.newTracker(TRACKER_ID);

        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
            @Override
            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {}

            @Override
            public void onActivityStarted(Activity activity) {
                tracker().setScreenName("My Activity");
                tracker().send(new HitBuilders.ScreenViewBuilder().build());
                analytics().reportActivityStart(activity);
            }

            @Override
            public void onActivityResumed(Activity activity) {}

            @Override
            public void onActivityPaused(Activity activity) {}

            @Override
            public void onActivityStopped(Activity activity) {
                analytics().reportActivityStop(activity);
            }

            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {}

            @Override
            public void onActivityDestroyed(Activity activity) {}
        });
    }
}

对于不同的配置，我有不同的TrackingID，所以我不能从xml中膨胀跟踪程序（因为我不能从xml中引用字符串资源）

我已经在代码中启用了自动活动跟踪，但我找不到任何API来自定义将出现在报告中的屏幕名称。相反，我在报告中看到了完整的活动名称

有一种方法，但它似乎意味着手动活动跟踪

如何在代码中模拟tracker xml文件中的屏幕配置？通常是这样的：

    GoogleAnalytics analytics = GoogleAnalytics.getInstance(context);
    tracker = analytics.newTracker(context.getString(R.string.ga_tracking_id));
    tracker.enableAutoActivityTracking(true);

<!-- The screen names that will appear in reports -->
<screenName name="com.mycompany.MyActivity">MyActivity Screen Name</screenName>

public class MyApp extends Application {
    private final String TRACKER_ID = "UA-12345678-1";

    private static GoogleAnalytics analytics;
    private static Tracker tracker;

    public static GoogleAnalytics analytics() {
        return analytics;
    }

    public static Tracker tracker() {
        return tracker;
    }

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

        analytics = GoogleAnalytics.getInstance(this);
        // analytics.getLogger().setLogLevel(Logger.LogLevel.VERBOSE);
        tracker = analytics.newTracker(TRACKER_ID);

        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
            @Override
            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {}

            @Override
            public void onActivityStarted(Activity activity) {
                tracker().setScreenName("My Activity");
                tracker().send(new HitBuilders.ScreenViewBuilder().build());
                analytics().reportActivityStart(activity);
            }

            @Override
            public void onActivityResumed(Activity activity) {}

            @Override
            public void onActivityPaused(Activity activity) {}

            @Override
            public void onActivityStopped(Activity activity) {
                analytics().reportActivityStop(activity);
            }

            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {}

            @Override
            public void onActivityDestroyed(Activity activity) {}
        });
    }
}

MyActivity屏幕名称

使用自动活动跟踪时，Google Analytics v4 API不提供在代码中设置屏幕名称的方法。您需要禁用自动活动跟踪

tracker.enableAutoActivityTracking（false）

并从

onActivityStarted（）调用
GoogleAnalytics.reportActivityStart（activity）
，从
onActivityStop（）调用

以下是指向应用程序活动生命周期回调的链接：

您的代码将如下所示：

    GoogleAnalytics analytics = GoogleAnalytics.getInstance(context);
    tracker = analytics.newTracker(context.getString(R.string.ga_tracking_id));
    tracker.enableAutoActivityTracking(true);

<!-- The screen names that will appear in reports -->
<screenName name="com.mycompany.MyActivity">MyActivity Screen Name</screenName>

public class MyApp extends Application {
    private final String TRACKER_ID = "UA-12345678-1";

    private static GoogleAnalytics analytics;
    private static Tracker tracker;

    public static GoogleAnalytics analytics() {
        return analytics;
    }

    public static Tracker tracker() {
        return tracker;
    }

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

        analytics = GoogleAnalytics.getInstance(this);
        // analytics.getLogger().setLogLevel(Logger.LogLevel.VERBOSE);
        tracker = analytics.newTracker(TRACKER_ID);

        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
            @Override
            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {}

            @Override
            public void onActivityStarted(Activity activity) {
                tracker().setScreenName("My Activity");
                tracker().send(new HitBuilders.ScreenViewBuilder().build());
                analytics().reportActivityStart(activity);
            }

            @Override
            public void onActivityResumed(Activity activity) {}

            @Override
            public void onActivityPaused(Activity activity) {}

            @Override
            public void onActivityStopped(Activity activity) {
                analytics().reportActivityStop(activity);
            }

            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {}

            @Override
            public void onActivityDestroyed(Activity activity) {}
        });
    }
}

谢谢，这很聪明。我有一个问题：是否有必要调用
分析。reportActivityStart
和
分析。reportActivityStop
，因为我们使用
跟踪器发送屏幕点击。是否仍要发送
？研究表明，这种方法只有在跟踪器打开自动活动报告时才有价值，但我们刚刚关闭了它，对吗？
