Question

Helo，我正在使用通知构建应用程序。我想在用户点击通知时将他发送到Fragment1。这几乎在所有情况下都没问题，除了一个。我的问题是当app只安装（从未启动）并且通知到来时，用户不会发送到Fragment1，然后他被发送到MainActivity ......我该怎么办？办？

这是myFirebaseMessagingService：

public class myFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG="MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d(TAG, "From " + remoteMessage.getFrom());
    Log.d(TAG, "Body " + remoteMessage.getNotification().getBody());
    sendNotification(remoteMessage);
    Log.d("Msg", "Poruka je stigla");
}

private void sendNotification(RemoteMessage remoteMessage){
    Intent intent=new Intent(myFirebaseMessagingService.this, MainActivity.class);
    intent.putExtra("action", "goToFragment1");
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent=PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notification=new NotificationCompat.Builder(this)
            .setSmallIcon(logo)
            .setContentText(remoteMessage.getNotification().getBody())
            .setContentTitle("Naslov")
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);
    NotificationManager notificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notification.build());



}

这是我的主要活动：

public class MainActivity extends AppCompatActivity {
Button dugme, dugme2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d("onCreate", "ONCREATE");
    setContentView(R.layout.activity_main);
    Intent intent = getIntent();
    String msg = getIntent().getStringExtra("action");
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    if (msg != null) {
        if (msg.equals("goToFragment1")) {
            Fragment1 fragment1 = new Fragment1();
            fragmentTransaction.replace(R.id.myFragment, fragment1);
            Log.d("FragmentTransaction", "Fragment je promenjen u onCreate!");
            fragmentTransaction.commit();
            Log.d("Create", "Kraj onCreatea");
        }
    }

    dugme = (Button) findViewById(R.id.dugme1);
    dugme2 = (Button) findViewById(R.id.subscribe);
    dugme.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Fragment fragment = null;
            if (view == dugme) {
                fragment = new Fragment1();
            }
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            transaction.replace(R.id.myFragment, fragment);
            transaction.addToBackStack(null);
            transaction.setTransition(FragmentTransaction.TRANSIT_NONE);
            transaction.commit();
        }
    });


    dugme2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FirebaseMessaging.getInstance().subscribeToTopic("android");
            Log.d("Log", "Uspesno ste se pretplatili");
        }
    });

}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    Log.d("onNewIntent", "NewIntent");
    handleIntentExtra(intent);
}

private void handleIntentExtra(Intent intent) {
    String msg = intent.getStringExtra("action");
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    if (msg != null) {
        if (msg.equals("goToFragment1")) {
            Fragment1 fragment1 = new Fragment1();
            fragmentTransaction.replace(R.id.myFragment, fragment1);
            fragmentTransaction.commit();
        }


    }
}

首次运行应用程序时，它将转到MainActivity中的onCreate方法。你有这两行代码 Fragment1 fragment1 = new Fragment1（）; fragmentTransaction.replace（R.id.myFragment，fragment1）;

试试这个： fragmentTransaction.add（R.id.myFragment，fragment1）;

我建议将片段添加到后台。

如何在第一次启动应用之前从通知中获取片段？
