【中文标题】如何使用 OneSignal 打开特定活动?【英文标题】:How to open a specific activity using OneSignal? 【发布时间】:2018-07-24 22:26:01 【问题描述】: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活动。 如果我想打开另一个特定的活动,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);
【问题讨论】:
【参考方案1】:这将是您的 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求(更改数据的值和类的名称)。
我试图设置一个空的附加数据来打开 MainActivity,但是,这在我的情况下不起作用。可能是因为我已经定义了:
<meta-data
android:name="com.onesignal.NotificationOpened.DEFAULT"
android:value="DISABLE"/>
在 AndroidManifest.xml 中。所以,我想,如果你需要,你还必须设置另一个额外的数据值来打开 MainActivity。只需在已包含的else if
之后添加另一个else if
,即可继续添加更多要启动的密钥和活动。
如果您要使用所有这些意图,请确保在您的 AndroidManifest.xml 中没有为您将使用通知启动的活动设置任何 android:launchMode
。基本上,它不应该存在。
此外,要使这件事正常工作,您必须将 AndroidManifest.xml 更改为以下内容:
<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">
此代码中用于通知工作的唯一强制性部分是android:name=".ApplicationClass"
。
希望这会有所帮助。
