因此，我编写了一些代码，使应用程序在指定的时间显示。当应用在屏幕上打开时，它运行良好，但是当它关闭时，它根本不起作用。我需要帮助使其显示出来。
MainActivity.java的代码：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initChannels(this);
alarmMgr = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, MyReceiver.class);
alarmIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
// Set the alarm to start at 8:30 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 9);
calendar.set(Calendar.MINUTE, 00);
// setRepeating() lets you specify a precise custom interval--in this case,
// 20 minutes.
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, alarmIntent);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
扩展了BroadcastReceiver的MyReceiver.java的代码：
public MyReceiver() {
}
@Override
public void onReceive(Context context,Intent intent) {
Intent intent1 = new Intent(context, MyNewIntentService.class);
context.startService(intent1);
}
扩展了IntentService的MyNewIntentService的代码：
private static final int notificationId = 4242;
public MyNewIntentService() {
super("MyNewIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
//NOTIFICATION CREATION
// Create an explicit intent for an Activity in your app
Intent notifyIntent = new Intent(this, MainActivity.class);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notifyIntent, 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "default")
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setContentTitle("This is the title")
.setContentText("This is the body of the notification.")
.setVisibility(VISIBILITY_PUBLIC)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
// Set the intent that will fire when the user taps the notification
.setContentIntent(pendingIntent)
.setAutoCancel(true);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
// notificationId is a unique int for each notification that you must define
notificationManager.notify(notificationId, mBuilder.build());
}
我在AndroidManifest.xml中添加了它：
<receiver
android:name=".MyReceiver"
android:enabled="true"
android:exported="false" >
</receiver>
<service
android:name=".MyNewIntentService"
android:exported="false" >
</service>
我知道这个问题中有很多文字，对此我深表歉意，但是我认为这样可以使您更轻松地帮助我或查看问题所在。

尝试
firebase通知有两种类型：
数据消息：当您的应用背景/前景/杀死了您的推送通知时
显示消息：当您的应用程序前台推送通知有效时
在这些阶段处理推送通知背景/前景/已杀死
这取决于您的 json响应，请确保您的json响应如下：
{
"to": "registration_ids",
"data": {
"key": "value",
"key": "value",
"key": "value",
"key": "value"
}
}
这是我的代码，当您的应用背景/前景/已终止正常运行
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.e(TAG, "remoteMessage......" + remoteMessage.getData());
try {
Map<String, String> params = remoteMessage.getData();
JSONObject object = new JSONObject(params);
Log.e(TAG, object.toString());
body = object.getString("not_id");
dataa = object.getString("data");
title = object.getString("not_type");
type = object.getString("type");
Sender = object.getString("Sender");
SenderProfileUrl = object.getString("SenderProfileUrl");
wakeUpScreen();
addNotification(remoteMessage.getData());
}
/* when your phone is locked screen wakeup method*/
private void wakeUpScreen() {
PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE);
boolean isScreenOn = pm.isScreenOn();
Log.e("screen on......", "" + isScreenOn);
if (isScreenOn == false) {
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "MyLock");
wl.acquire(10000);
PowerManager.WakeLock wl_cpu = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyCpuLock");
wl_cpu.acquire(10000);
}
}
/*Add notification method use for add icon and title*/
private void addNotification(Map<String, String> data) {
int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ?R.drawable.logo_app: R.drawable.logo_app;
NotificationCompat.Builder builder =
new NotificationCompat.Builder(this)
.setSmallIcon(icon)
//.setSmallIcon(R.drawable.logout_icon)
.setContentTitle(data.get("title") + "")
.setChannelId("channel-01")
.setAutoCancel(true)
.setSound(uri)
.setContentText(data.get("body") + "");
Notification notification = new Notification();
Log.e(TAG, "titlee" + data.get("title"));
// Cancel the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;
if (sound)
notification.defaults |= Notification.DEFAULT_SOUND;
if (vibration)
notification.defaults |= Notification.DEFAULT_VIBRATE;
builder.setDefaults(notification.defaults);
}
}
当我单击通知栏时，使用如下类型转到特定屏幕：
/*notification send with type calling */
if (data.get("not_type").equals("calling")) {
if (data.get("type").equals("name")) {
Log.e(TAG, "ttt--" + type);
Intent notificationIntent = new Intent(this, CallingActivity.class);
notificationIntent.putExtra("notification_room_id", body);
notificationIntent.putExtra("data", dataa);
notificationIntent.putExtra("calling", "calling");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIntent);
builder.setSound(uri);
builder.setAutoCancel(true);
// Add as notification
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "Hello";// The user-visible name of the channel.
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = new NotificationChannel("channel-01", name, importance);
manager.createNotificationChannel(mChannel);
}
manager.notify((int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE), builder.build());
}
这是我的清单添加通知类和令牌类
<service android:name=".notification.NotificationService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".notification.TokenService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service
android:name=".notification.NLService"
android:label="@string/app_name"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
我希望它对您有帮助
