我创建了发送推送通知的应用。一切都运作良好。如果应用程序正在运行或未关闭,则会直接转到第二页。但问题是,运行我的应用程序后如果我将我的应用程序放在后台或关闭它,然后发送通知。点击通知后,它会转到主页而不是第二页。即使应用已关闭或在后台,我希望它必须带我到第二页。 以下是我的代码:
MainActivity.java
public class MainActivity extends Activity {
private static final String TAG="MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button BtnshowToken=(Button)findViewById(R.id.buttonshowtoken);
BtnshowToken.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String token= FirebaseInstanceId.getInstance().getToken();
Log.d(TAG,"Token: "+token);
Toast.makeText(MainActivity.this,token,Toast.LENGTH_SHORT).show();
}
});
}
}
MyFirebaseInstanceIDService.java
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG="MyFirebaseInsIDService";
@Override
public void onTokenRefresh() {
//get updated token
String refreshedToken= FirebaseInstanceId.getInstance().getToken();
Log.d(TAG,"New Token: "+refreshedToken);
}
}
MyFirebaseMessagingService.java
public class MyFirebaseMessagingService extends FirebaseMessagingService{
private static final String TAG="MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "FROM:" +remoteMessage.getFrom());
//Check if msg contains data
if(remoteMessage.getData().size() > 0){
Log.d(TAG, "Message data: "+remoteMessage.getData());
}
//Check if msg contains notification
if(remoteMessage.getNotification()!=null){
Log.d(TAG,"Message body: "+remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
}
//Display notification
private void sendNotification(String body){
Intent intent=new Intent(this,SecondActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent=PendingIntent.getActivity(this, 0/*Request code*/, intent, PendingIntent.FLAG_ONE_SHOT);
//Set sound of notification
Uri notificationsound= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notifiBuilder=new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Firebase Cloud Messaging")
.setContentText(body)
.setAutoCancel(true)
.setSound(notificationsound)
.setContentIntent(pendingIntent);
NotificationManager notificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0/*Id of notification*/,notifiBuilder.build());
}
}
SecondActivity.java
public class SecondActivity extends Activity {
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
}

您需要从服务器请求中单击ClickListener,并在您的活动中的清单intent-action中添加侦听器名称。
"notification" : {
"body" : "Body",
"title" : "Titme",
"icon" : "YourIcon"
"click_action" : "<<yourkey e.g. MainActivity>>"
}
<activity
android:name=".MainActivity">
<intent-filter>
<action android:name="<<yourkey e.g. MainActivity>>" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
这适用于您的应用在前台无法使用的情况。 希望这有用,谢谢

如果应用程序处于后台并且您单击通知,则数据将存储在intent的附加内容中。所以你需要的是firebase请求中的 action_code 。这是一个例子:
Firebase请求:
{
"to": "/topics/order",
"priority": "high",
"notification": {
"title": "Hello admin",
"body":"There's new order :)",
"sound":"default"
},
"data": {
"msgCode":"newOrder"
}
}
<强> MainActivity.java 强>
Intent intent = getIntent();
if (intent.hasExtra("msgCode")) {
String msgCode = intent.getStringExtra("msgCode");
if (msgCode.equals("newOrder")) {
Toast.makeText(this, "newOrder", Toast.LENGTH_SHORT).show();
Log.i("zihad", "newOrder");
startActivity(new Intent(this, ListOrderActivity.class));
intent.removeExtra("msgCode");
}
}
