如何使用 OneSignal 打开特定的 activity？

Question

我正在使用 onesignal 发送推送通知。当用户单击推送通知时，我使用此示例代码打开特定的 activity。如果我想打开另一个特定的activity，我应该怎么做？

 package com.moho.app;

    import android.content.Intent;
    import android.util.Log;
    import android.widget.Toast;

    import com.onesignal.OSNotificationAction;
    import com.onesignal.OSNotificationOpenResult;
    import com.onesignal.OneSignal;

    import org.json.JSONObject;


    public class MyNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler {
        // This fires when a notification is opened by tapping on it.
        @Override
        public void notificationOpened(OSNotificationOpenResult result) {
            OSNotificationAction.ActionType actionType = result.action.type;
            JSONObject data = result.notification.payload.additionalData;
            String activityToBeOpened;
            String activity;

            //While sending a Push notification from OneSignal dashboard
            // you can send an addtional data named "activityToBeOpened" and retrieve the value of it and do necessary operation
            //If key is "activityToBeOpened" and value is "AnotherActivity", then when a user clicks
            //on the notification, AnotherActivity will be opened.
            //Else, if we have not set any additional data MainActivity is opened.
            if (data != null) {
                activityToBeOpened = data.optString("activityToBeOpened", null);
                if (activityToBeOpened != null && activityToBeOpened.equals("AnotherActivity")) {
                    Log.i("OneSignalExample", "customkey set with value: " + activityToBeOpened);
                    Intent intent = new Intent(MainMenu.getContext(), AboutUs.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
                    MainMenu.getContext().startActivity(intent);

                } else if (activityToBeOpened != null && activityToBeOpened.equals("MainActivity")) {
                    Log.i("OneSignalExample", "customkey set with value: " + activityToBeOpened);
                    Intent intent = new Intent(MainMenu.getContext(), MainMenu.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
                    MainMenu.getContext().startActivity(intent);
                } else {
                    Intent intent = new Intent(MainMenu.getContext(), MainMenu.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
                    MainMenu.getContext().startActivity(intent);
                }

            }

    }

这将是您 ApplicationClass.java 的代码：

package com.application;

import android.app.Application;
import android.content.Intent;
import android.util.Log;
import com.onesignal.OSNotificationAction;
import com.onesignal.OSNotificationOpenResult;
import com.onesignal.OneSignal;
import org.json.JSONObject;

@SuppressWarnings("unused")

public class ApplicationClass extends Application
{
    @Override
    public void onCreate()
    {
        super.onCreate();

        OneSignal.startInit(this)
                .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
                .setNotificationOpenedHandler(new NotificationOpenedHandler())
                .unsubscribeWhenNotificationsAreDisabled(true)
                .init();
    }

    public class NotificationOpenedHandler implements OneSignal.NotificationOpenedHandler
    {
        @Override
        public void notificationOpened(OSNotificationOpenResult result)
        {
            OSNotificationAction.ActionType actionType = result.action.type;
            JSONObject data = result.notification.payload.additionalData;
            String activityToBeOpened;
            String activity;

            if (data != null)
            {
                activityToBeOpened = data.optString("activityToBeOpened", null);
                if (activityToBeOpened != null && activityToBeOpened.equals("ABC"))
                {
                    Log.i("OneSignal", "customkey set with value: " + activityToBeOpened);
                    Intent intent = new Intent(ApplicationClass.this, ABCActivity.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NO_HISTORY);
                    startActivity(intent);
                } else if (activityToBeOpened != null && activityToBeOpened.equals("DEF"))
                {
                    Intent intent = new Intent(ApplicationClass.this, DEFActivity.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NO_HISTORY);
                    startActivity(intent);
                }
            }
        }
    }
}

自定义代码以满足您的需要（更改数据的值和 class 的名称）。

我试图设置一个空的附加数据来打开 MainActivity，但是，这对我来说不起作用。可能是因为我定义了：

<meta-data
            android:name="com.onesignal.NotificationOpened.DEFAULT"
            android:value="DISABLE"/>

在 AndroidManifest.xml 中。所以，我想，如果需要，您还必须设置另一个附加数据值才能打开 MainActivity。只需在已经包含的那些之后添加另一个 else if 以继续添加更多要启动的键和活动。

如果您要使用所有这些意图，请确保在您的 AndroidManifest.xml 中没有为 android:launchMode 设置任何您将使用通知启动的活动.基本上不应该存在

此外，要使它正常工作，您必须将 AndroidManifest.xml 更改为如下内容：

<application
        android:name=".ApplicationClass"
        android:allowBackup="true"
        android:fullBackupContent="@xml/backup_descriptor"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:ignore="AllowBackup">

此代码中为使通知正常工作而必须执行的唯一部分是 android:name=".ApplicationClass"。

希望对您有所帮助。
