假设已经执行过reaact-native init AwesomeProject,生成了AwesomeProject
打开AwesomeProject文件夹,看到如下目录结构:
用Android Studio打开AwesomeProject/android文件夹,
1)运行项目
通过数据线连接好android手机,点击上图,三角箭头运行项目,
可能的报错:
如果项目报:No target device found,
报错则需改app/build.gradle,修改version为Android SDK Manager里有的版本
修改version install的都可以2)编写RN页面
1、RN js调用java方法
RN js ——> (调用) ReactContextBaseJavaModule———>(注册到)ReactPackage ———>(注册到) ReactApplication
2、页面跳转—>原生嵌套RN
java代码:
public class DemoTwo extends ReactActivity {
private ReactRootView mReactRootView;
private ReactInstanceManager mReactInstanceManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo_two);
mReactRootView = (ReactRootView) findViewById(R.id.react_root);
mReactInstanceManager = ReactInstanceManager.builder()
.setApplication(getApplication())
.setBundleAssetName("index.android.bundle")
.setJSMainModuleName("index.android")
.addPackage(new MainReactPackage())
.setUseDeveloperSupport(BuildConfig.DEBUG)
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();
mReactRootView.startReactApplication(mReactInstanceManager, "HelloWorld", null);
}
}
原生页面嵌入:
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
android:id="@+id/react_root"
android:layout_width="match_parent"
android:layout_height="match_parent" />
3、页面跳转—>原生跳转RN
原生链接点击,跳转RN,CNodeListActivity实现了ReactActivity接口
@Click(R.id.ll_publish_house)
public void houseRelease() {
Intent intent = new Intent(getActivity(), CNodeListActivity.class);
startActivity(intent);
}
4、页面跳转—>RN跳转原生
调用ReactContextBaseJavaModule的方法
