从firebase通知中打开特定活动

标签: android firebase notifications

我将firebase通知集成到了我的应用程序中,但我想发送一个通知,打开一个特定的活动,按照我的计划做,而不仅仅是打开应用程序。比如通知会在用户点击它时访问Google Play商店。

我看到了我使用的代码Firebase console: How to specify click_action for notifications,但是初始化变量cls时出错了。我尝试通过定义cls = null来解决,以清除错误。它无法使用click_action

打开我指定的活动
public class ClickActionHelper { 
public static void startActivity(String className, Bundle extras, Context context){ 
Class cls=null; 
try { cls = Class.forName(className);
 }
catch(ClassNotFoundException e){ 
 //means you made a wrong input in firebase console 
} 
Intent i = new Intent(context, cls);
 i.putExtras(extras); context.startActivity(i); 
}     
}

我有什么不对吗?我如何让它工作?

如果您要打开应用并执行特定操作[在后台运行时],请在通知有效内容中设置click_action,并将其映射到您要启动的活动中的意图过滤器。例如,将click_action设置为OPEN_ACTIVITY_1以触发如下所示的意图过滤器:

正如FCM文档中所建议的那样,请求后端以这样的形式发送JSON数据,

{
    "to": "some_device_token",

    "content_available": true,
    "notification": {
        "title": "hello",
        "body": "yo",
        "click_action": "OPEN_ACTIVITY_1" // for intent filter in your activity
    },

    "data": {
        "extra": "juice"
    }
}

并在您的mainfest文件中为您的活动添加intent-filter,如下所示

<intent-filter>
  <action android:name="OPEN_ACTIVITY_1" />
  <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

当您点击通知时,它会打开应用并直接转到您在click_action中定义的活动,在本例中为&#34; OPEN_ACTIVTY_1&#34;。在该活动中,您可以通过以下方式获取数据:

Bundle b = getIntent().getExtras();// add these lines of code to get data from notification
String someData = b.getString("someData");

我知道这个问题已经存在了一段时间,但无论如何我想展示我的解决方案。它比那些简单得多。所以现在我徘徊,如果它的坏习惯。但它有效: 我使用有效负载json对象来存储整数:

JSONObject payload = data.getJSONObject("payload");
int destination = payload.getInt("click_action");

然后我只使用一个简单的switch语句来根据整数结果启动正确的活动:

Intent resultIntent;
switch(destination){
    case 1:
        resultIntent = new Intent(getApplicationContext(), UserProfileActivity.class);
        resultIntent.putExtra("message", message);
        break;
    default:
        resultIntent = new Intent(getApplicationContext(), MainActivity.class);
        resultIntent.putExtra("message", message);
        break;
}

简单。

<activity android:name=".design.NotificationActivity"
        android:launchMode="singleTask"
        android:taskAffinity=""
        android:excludeFromRecents="true"
        android:parentActivityName=".MainActivity"
        >
        <intent-filter>
            <action android:name="NotificationActivity" />
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>

    </activity>

        $ url = "https://fcm.googleapis.com/fcm/send";
        $token = "";
        $serverKey = '';
        $title = "your title";
        $body = "mesaage";
        $notification = array('title' =>$title ,
        'body' => $body, 
        'sound' => 'default',
        'badge' => '1',
        'click_action' => 'NotificationActivity'
        );
        $arrayToSend = array('to' => $token, 'notification' => $notification,'priority'=>'high');
        $json = json_encode($arrayToSend);
        $headers = array();
        $headers[] = 'Content-Type: application/json';
        $headers[] = 'Authorization: key='. $serverKey;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"POST");
        curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
        curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
        //Send the request
        $response = curl_exec($ ch);
        //Close request
        if ($response === FALSE) {
        die('FCM Send Error: ' . curl_error($ch));
        }
        curl_close($ch)
