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';

...

  onPress={() =>

  NativeModules.IntentModule.startActivityFromJS("com.wildwolf.myrn.ThridActivity","我是从JS传过来的参数信息.")}>

  Click me.
