應(yīng)用場景

1.app在前臺狀態(tài)時，在app內(nèi)推送
2.app在后臺狀態(tài)時，在消息欄推送

集成Jpush

極光推送集成Android 看看文檔，先把sdk集成到項目內(nèi)

邏輯分析

1. 我們需要自定義Receiver 去接受jpush發(fā)送過來的消息
2. 在接受到的消息中判斷app在前臺狀態(tài)還是后臺狀態(tài)
3. 根據(jù)前后臺狀態(tài)做出對應(yīng)的業(yè)務(wù)需求

 @Override
    public void onReceive(Context context, Intent intent) {
        try {
            Bundle bundle = intent.getExtras();
            MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] onReceive - " + intent.getAction() + ", extras: " + printBundle(bundle));
            //判斷當(dāng)前app的狀態(tài)是（前臺，activity可見為前臺)還是（后臺，activity不可見為后臺）
            if (AppUtils.isAppOnForeground(context) &&MainApplication.getInstance().getForeground()) {
                //前臺狀態(tài)
                JPushInterface.clearAllNotifications(context);
                MyLogUtils.INSTANCE.d(TAG,"在前臺。。。。");
                if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {
                    MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 接收到推送下來的通知");
                    int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);
                    MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 接收到推送下來的通知的ID: " + notifactionId);
                    Activity activity = ApplicationUtils.currentActivity();
                    shouDialog(activity)
            } else {
                //后臺狀態(tài)
                MyLogUtils.INSTANCE.d(TAG,"在后臺。。。。");
                if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) {
                    String regId = bundle.getString(JPushInterface.EXTRA_REGISTRATION_ID);
                    MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 接收Registration Id : " + regId);
                    //send the Registration Id to your server...

                } else {
                    if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) {
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 接收到推送下來的自定義消息: " + bundle.getString(JPushInterface.EXTRA_MESSAGE));
                        processCustomMessage(context, bundle);

                    } else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 接收到推送下來的通知");
                        int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 接收到推送下來的通知的ID: " + notifactionId);

                    } else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 用戶點擊打開了通知");

                        //打開自定義的Activity
                        Intent i = new Intent(context, TaskDetailActivity.class);
                        i.putExtras(bundle);
                        //i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
                        context.startActivity(i);

                    } else if (JPushInterface.ACTION_RICHPUSH_CALLBACK.equals(intent.getAction())) {
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] 用戶收到到RICH PUSH CALLBACK: " + bundle.getString(JPushInterface.EXTRA_EXTRA));
                        //在這里根據(jù) JPushInterface.EXTRA_EXTRA 的內(nèi)容處理代碼，比如打開新的Activity， 打開一個網(wǎng)頁等..

                    } else if (JPushInterface.ACTION_CONNECTION_CHANGE.equals(intent.getAction())) {
                        boolean connected = intent.getBooleanExtra(JPushInterface.EXTRA_CONNECTION_CHANGE, false);
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver]" + intent.getAction() + " connected state change to " + connected);
                    } else {
                        MyLogUtils.INSTANCE.d(TAG, "[MyReceiver] Unhandled intent - " + intent.getAction());
                    }
                }
            }

        } catch (Exception e) {

        }

設(shè)置消息欄的屬性

BasicPushNotificationBuilder builder = new BasicPushNotificationBuilder(this);
        builder.statusBarDrawable = R.drawable.jpush_notification_icon;

        builder.notificationFlags = Notification.FLAG_AUTO_CANCEL;  //設(shè)置為點擊后自動消失
        builder.notificationDefaults = Notification.DEFAULT_SOUND;  //設(shè)置為鈴聲（ Notification.DEFAULT_SOUND）或者震動（ Notification.DEFAULT_VIBRATE）

        JPushInterface.setPushNotificationBuilder(100, builder);//100 這個屬性看文檔

這里有個細節(jié)，當(dāng)你設(shè)置了這段代碼，你有可能發(fā)現(xiàn)消息欄上的logo沒有改變，這個時候你重啟下手機就好了

結(jié)語

記一次需求，方便以后萬一開發(fā)相同的需求用到，也說不定哪個小伙伴有類似的需求可以參考一下呢，好記性不如爛筆頭，下次見咯。
