从React Native 跳转到原生页面

温故知新,记录一下吧,免得自己忘了

1.MyIntentModule.java 类

public class MyIntentModule extends ReactContextBaseJavaModule {
public MyIntentModule(ReactApplicationContext reactContext) { super(reactContext); }
@Override public String getName() { return "IntentModule"; }
/** * 从JS页面跳转到原生activity 同时也可以从JS传递相关数据到原生 * @param name 需要打开的Activity的class * @param params */ @ReactMethod public void startActivityFromJS(String name, String params){ try{ Activity currentActivity = getCurrentActivity(); if(null!=currentActivity){ Class toActivity = Class.forName(name); Intent intent = new Intent(currentActivity,toActivity); intent.putExtra("params", params); currentActivity.startActivity(intent); } }catch(Exception e){ throw new JSApplicationIllegalArgumentException( "不能打开Activity : "+e.getMessage()); } } } 2.MyReactPackage.java类 public class MyReactPackage implements ReactPackage { @Override public List createNativeModules(ReactApplicationContext reactContext) { return Arrays.asList( new MyIntentModule(reactContext) ); }
@Override public List> createJSModules() { return Collections.emptyList(); }
@Override public List createViewManagers(ReactApplicationContext reactContext) { return Collections.emptyList();
} } 3.MainApplication添加 new MyReactPackage() 4.随便创建一个Activity页面（com.wildwolf.myrn.ThridActivity ） 5.index.android.js
import { ... NativeModules } from 'react-native'; ... NativeModules.IntentModule.startActivityFromJS("com.wildwolf.myrn.ThridActivity","我是从JS传过来的参数信息.")}> Click me.
