FCM 如何显示来自通知的数据单击另一个活动

我有一个接收FCM通知的应用程序，我想在另一个活动中显示通知和数据有效负载的内容，我的挑战是当我单击通知时，它会将我定向到所需的活动，但我没有得到显示的信息。

请帮忙，以下是我的代码

MyFirebaseMessagingService
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
//you can get your text message here.
if (remoteMessage.getData().size() > 0) {
Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());
try {
String storedData = remoteMessage.getData().toString();
//  JSONObject json = new JSONObject(storedData);
JSONArray arr = new JSONArray(storedData);
JSONObject jObj = arr.getJSONObject(0);
String title = jObj.getString("title");
String message = jObj.getString("body");
sendPushNotification(jObj);
final String MY_PREFS_NAME = "MyFCMFile";
SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
editor.putString("Title", title);
editor.putString("Message", message);
editor.apply();
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
else {
String title = remoteMessage.getNotification().getTitle();
String message = remoteMessage.getNotification().getBody();
String click_action = remoteMessage.getNotification().getClickAction();
Intent intent = new Intent(click_action);
intent.addFlags(intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setContentTitle(title);
notificationBuilder.setContentText(message);
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
notificationBuilder.setAutoCancel(true);
notificationBuilder.setContentIntent(pendingIntent);
final String MY_PREFS_NAME = "MyFCMFile";
SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
editor.putString("Title", title);
editor.putString("Message", message);
editor.apply();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());

}
}
//this method will display the notification
//We are passing the JSONObject that is received from
//firebase cloud messaging
private void sendPushNotification(JSONObject json) {
//optionally we can display the json into log
Log.e(TAG, "Notification JSON " + json.toString());
try {
//getting the json data
JSONObject data = json.getJSONObject("data");
//parsing json data
String title = data.getString("title");
String message = data.getString("message");
String imageUrl = data.getString("image");
final String MY_PREFS_NAME = "MyFCMFile";
SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
editor.putString("Title", title);
editor.putString("Message", message);
editor.apply();
//creating MyNotificationManager object
MyNotificationManager mNotificationManager = new MyNotificationManager(getApplicationContext());
// CREATE CLICK ACTION
//creating an intent for the notification
Intent intent = new Intent(getApplicationContext(), Notifications.class);
//if there is no image
if (imageUrl.equals("null")) {
//displaying small notification
mNotificationManager.showSmallNotification(title, message, intent);
} else {
//if there is an image
//displaying a big notification
mNotificationManager.showBigNotification(title, message, imageUrl, intent);
}
} catch (JSONException e) {
Log.e(TAG, "Json Exception: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
}

通知.java

package com.example.workman;
import android.content.SharedPreferences;
import android.support.annotation.IdRes;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class Notifications extends AppCompatActivity {
TextView title, message;
String txtTitle, txtMessage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notifications);
title = (TextView)findViewById(R.id.category);
message = (TextView)findViewById(R.id.type);


final String MY_PREFS_NAME = "MyFCMFile";
SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE);
String txtTitle = prefs.getString("Title", "");//"No name defined" is the default value.
String txtMessage = prefs.getString("Message", "");//"No name defined" is the default value.
title.setText(txtTitle);
message.setText(txtMessage);
}
}

根据 FCM 文档，您似乎以错误的方式执行此操作。

仅当应用已在前台运行时，才会调用onMessageReceived()。

否则，Android 将显示通知(使用"通知"字典的属性)并使用getClickAction()值打开所需的Activity，而无需编写任何代码。

您可以通过启动器活动意图的额外功能获取"数据"有效载荷。

即在您的Notifications课上：

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle extras = getIntent ().getExtras (); // you should find the data here
...
}

以下是对我有用的方法：

在我的第二个Activity类(单击通知时应该打开的那个)中，我输入：

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
TextView text    = (TextView) findViewById(R.id.data2);
if (text != null) {
Bundle extras = getIntent ().getExtras ();
StringBuilder keys = new StringBuilder();
if (extras != null) {
for (String key : extras.keySet())
keys.append(key + " = " + extras.getString(key) + "n ");
}
text.setText("extras on second activity: " + keys.toString());
}
}

我得到了以下输出：

extras on second activity: google.sent_time = null
msg - some value (this is a key/value pair I included in the "data" dictionary)
uri - some value (this is a key/value pair I included in the "data" dictionary)
from - <the sender id>
google.message_id - <the message id returned in the receipt of the HTTP response>
collapse_key - com.package.fcmdemo (default value)

如您所见，我的(自定义)"数据"字典的属性都传递给了活动。"通知"字典的属性没有传递，但我假设这是有意为之的(因为它们已经用于显示我单击以打开活动的通知)。
