Question

我正在尝试使用FCM开发推送通知。我能够在我的设备上获得通知并点击通知，应用程序打开MainActivity页面（activity_main.xml）但它应该直接打开SecondActivity.java（second.xml）并且它还必须在Textview中显示通知消息。这是我的代码 -

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 AppCompatActivity {

     TextView tv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv=(TextView)findViewById(R.id.tv2);

    }
}

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" : "YourActivity"
}

<activity
     android:name=".SecondActivity">
     <intent-filter>
         <action android:name="YourActivity" />
         <category android:name="android.intent.category.DEFAULT" />
     </intent-filter>
</activity>

希望这有用，谢谢

Firebase推送通知必须打开第二个活动
