我想在MyCustomModuleClass中调用一个方法从另一个类中扩展ReactContextBaseJavaModule
MyCustomModule.java
public class MyCustomModule extends ReactContextBaseJavaModule {
private ReactContext mReactContext;
public MyCustomModule(ReactApplicationContext reactContext) {
super(reactContext);
mReactContext = reactContext;
}
@Override
public String getName() {
return "CustomModule";
}
private void sendEvent(String eventName, Object params) {
mReactContext
.getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
.emit(eventName, params);
}
}
我正在尝试这个..
OtherClass.java
public class OtherClass extends AnotherClass {
@Override
protected void eventOccurred(Context context) {
MyCustomModule RNC = new MyCustomModule(?);//-> Can't call without ReactContext
RNC.sendEvent("CustomEvent", ObjectData);
}
}
对不起,我对java一无所知,有人可以帮帮我吗?
有没有办法在OtherClass中获得ReactContext?
答案 0 :(得分:0)
这是我在FirebaseMessagingService
扩展类中的做法。
public class MyPushListener extends FirebaseMessagingService {
@Override
public void onMessageReceived(JSONObject message, JSONObject content){
MainApplication application = (MainApplication) this.getApplication();
ReactNativeHost reactNativeHost = application.getReactNativeHost();
ReactInstanceManager reactInstanceManager = reactNativeHost.getReactInstanceManager();
ReactContext reactContext = reactInstanceManager.getCurrentReactContext();
if (reactContext != null) {
WritableNativeArray params = new WritableNativeArray();
params.pushString(message.toString());
reactContext.getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
.emit("EVENT_HAS_TRIGGERED", params);
}
}
}
