@ReactMethod
void callJavaScript() {
Activity activity = getCurrentActivity();
if (activity != null) {
MainApplication application = (MainApplication) activity.getApplication();
ReactNativeHost reactNativeHost = application.getReactNativeHost();
ReactInstanceManager reactInstanceManager = reactNativeHost.getReactInstanceManager();
ReactContext reactContext = reactInstanceManager.getCurrentReactContext();
if (reactContext != null) {
CatalystInstance catalystInstance = reactContext.getCatalystInstance();
WritableNativeArray params = new WritableNativeArray();
params.pushString("Hello, JavaScript!");
catalystInstance.callFunction("JavaScriptVisibleToJava", "alert", params);
}
}
}
示例2: onCreate
import com.facebook.react.ReactInstanceManager; //导入方法依赖的package包/类
@Override
public void onCreate() {
ReactInstanceManager reactInstanceManager =
ReactInstanceSingleton.getReactInstanceManager(getApplication());
ReactContext reactContext = reactInstanceManager.getCurrentReactContext();

}
示例3: sendTokenToJS
import com.facebook.react.ReactInstanceManager; //导入方法依赖的package包/类
protected void sendTokenToJS() {
final ReactInstanceManager instanceManager = ((ReactApplication) mAppContext).getReactNativeHost().getReactInstanceManager();
final ReactContext reactContext = instanceManager.getCurrentReactContext();
// Note: Cannot assume react-context exists cause this is an async dispatched service.
if (reactContext != null && reactContext.hasActiveCatalystInstance()) {
reactContext.getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class).emit(TOKEN_RECEIVED_EVENT_NAME, sToken);
}
