在React Native上设置Android BroadcastReceiver

Question

我正在使用React Native构建应用程序,我想使用Android服务NotificationListenerService.为了从服务中捕获数据,我需要一个广播接收器.如何在React Native Environment中设置BroadcastReceiver？

Answer 1

我这样做的方式是emit使用事件getJSModule

MyListener.java

public class MyListener extends NotificationListenerService {

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {

        if (sbn.getNotification().tickerText == null) {
            return;
        }

        WritableNativeMap params = new WritableNativeMap();
        params.putString("tickerText", sbn.getNotification().tickerText.toString());
        params.putString("packageName", sbn.getPackageName());

        MyModule.sendEvent("notificationReceived", params);
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {}
}

MyModule.java

public class MyModule extends ReactContextBaseJavaModule implements ActivityEventListener {
    private static ReactApplicationContext reactContext;

    public MyModule(ReactApplicationContext reactContext) {
        super(reactContext);
        this.reactContext = reactContext;
        reactContext.addActivityEventListener(this);
    }

    public static void sendEvent(String event, WritableNativeMap params) {
        reactContext
            .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
            .emit(event, params);
    }
    .......
}

请在这里介绍了有关发送事件的详细信息.
