com.andorid.xx.Act; 23 | 24 | * 2、定义组件，结构化的代码： 25 | 26 | var { 27 | 28 | AppRegistry, 29 | 30 | StyleSheet, 31 | 32 | Text, 33 | 34 | View, 35 | 36 | } = React; 37 | 38 | * 3、React.createClass里的render方法就是渲染视图用的。return返回的是视图的模板代码。 39 | 40 | * 4、样式表现：那么StyleSheet.create就是干这件事的，只是用JS的自面量表达了css样式。 41 | 42 | * 5、引入css样式： 43 | 44 | 方法1：style={styles.container} 45 | 46 | 方法2：style={{width:20,height:100}} 47 | 48 | * 6、注册View组件，第二个参数为React.createClass创建的 那个var对象 49 | 50 | AppRegistry.registerComponent('aswsome', () => yourVar); 51 | 52 | #最新动态 53 | 15.10.28日React

-------------------------------------------------------------------------------- 1 | 2 | # Android ReactNative ImageView 的使用 3 | 4 | > 在使用RNAndroid 的 ToolbarAndroid时 ，关于navIcon标签的属性值，即设置左上角导航图片的资源路径时，发现直接尝试加载android apk包中的资源会失败： 5 | 6 | ![tp](http://s10.sinaimg.cn/mw690/001qH9BXgy6YmkDPml349&690) 7 | ## imageView source的 资源路径的设置 8 | > 主要有以下几种形式可供使用和操作： 9 | 10 | ### 1.根据当前 node 服务器的 资源绝对路径 11 | * 进行配置，验证可以正常显示： 12 | 13 | `` 14 | 15 | 16 | 17 | ### 2.根据给定的url 18 | * 直接显示，验证可以正常显示： 19 | 20 | `` 21 | 22 | ### 直接使用apk包中图片名 23 | 24 | * 在使用ToolbarAndroid 时可以看到 navIcon的属性值是支持直接传递apk包内的图片名的。 25 | 26 | * 即还有一种是 让js直接使用app的 res包下的drable资源，这里遇到了一些问题，按道理说，程序会自动去当前的app容器中起找，考虑到RN的消息通信的流转机制，毕竟最总绘制UI ,是发生在 native这一层，所以 picture 及 xml 等资源文件的路径索取，应该还是会回归到native那一次层，如果是是使用app包内的图片资源，那么按照官方给出的样例，后缀名是不用写的，这也是Android 本身推荐的方式。 27 | 28 | * 但是目前直接这样操作（apk包里已经有了 这个同名的文件ic_launcher.png），貌似是不能正常显示出来，官方是有给出这样的加载方式的case,但是我这边本地这样尝试，貌似没有成功，切换到上两种情况即ok了。不知道大家有没有遇到类似情况。 29 | 30 | `< Image source={{uri: 'ic_launcher'}} style={{width: 30, height: 30}} />` 31 | 32 | 33 | ## 对应官方Image 文档： 34 | [http://facebook.github.io/react-native/docs/image.html#content](http://facebook.github.io/react-native/docs/image.html#content) 35 | 36 | 37 | ## 源码分析及跟踪 38 | 39 | ### ImageRequestBuilder 40 | 根据红框的log,可以找到对应的ImageRequestBuilder类的代码【截图如下】， 41 | 从mathod的doc中可以看到,就是标准的ImageView是只支持network and local uris,那么 navIcon那个难道是自己拼的uri不成？ 42 | 43 | ![tp](http://s2.sinaimg.cn/mw690/001qH9BXgy6Ymmq55CNb1&690) 44 | ![tp](http://s15.sinaimg.cn/mw690/001qH9BXgy6Ymmq8j1Ace&690) 45 | 46 | 47 | 48 | 49 | ### ReactImageView 50 | 再去对照ReactAndroid 的 ReactImageView源码，可以看到在setSource方法中，对source的路径相关的合法性检验和处理，里面有个mIsDitrty的结果反馈。 51 | 52 | 另外，优先check了分发uri后，如果失败，则会继续调用ReactImageView的静态方法 getResourceDrawableUri（Context context , String name） 53 | 54 | ![tp](http://s10.sinaimg.cn/mw690/001qH9BXgy6YmmQzrJv59&690) 55 | 56 | ### getResourceDrawableUri 57 | getResourceDrawableUri 最终会执行通过下面React中如下代码获得DrawableId 58 | 59 | return context.getResources().getIdentifier( 60 | name.toLowerCase().replace("-", "_"), 61 | "drawable", 62 | context.getPackageName())` 63 | 64 | * 平时直接用getIdentifier（） 不是特别多，简单说明下方法参数介绍 65 | 66 | > Resources resources = context.getResources(); 67 | 68 | >intindentify= getResources().getIdentifier("icon", "drawable", "org.xx.package"); 69 | 70 | > 第一个参数为ID名，第二个为资源属性是ID或者是Drawable，第三个为包名。 71 | 72 | ### R.java 73 | 到gradle的build/generated/source/r/debug/package里可以找到R.java文件,去里面查一下是否有自己要用的那个 drawable名字 74 | 75 | 查了后 ，fuck ,果然没有 这个ic_launcher 的id名 76 | 77 | 78 | 79 | ### id 80 | 一路跟踪 。。。。。擦,写死了 drawable 这种type, 而新版本的Studio是推荐的mipmap文件夹。。。。。额 找到问题关键了 81 | 82 | ![](http://s11.sinaimg.cn/mw690/001qH9BXgy6YmoZpFLIba&690) 83 | ![](http://s1.sinaimg.cn/mw690/001qH9BXgy6YmoZutfq90&690) 84 | ![](http://s5.sinaimg.cn/mw690/001qH9BXgy6YmoZycRu64&690) 85 | 86 | 87 | 88 | ### mipmap 89 | 原来是 新的Android studio 现在新建的文件夹都是mipmap-xxdpi 而不是以前的drawable-xxdpi,自己也没有注意 90 | 91 | 具体的原因可以参考这里，http://segmentfault.com/q/1010000002603418 92 | 93 | 即官方后续也是推荐使用mipmap代替 drawable... 94 | 95 | ### 曙光 96 | 换成drawable 下 ，运行正常，采坑结束，基本了解了 js端imageView组件到native层加载搜索的逻辑了 97 | 98 | 99 |

http://localhost:8081/index.android.bundle?platform=android 10 | 11 | #2.可能第一次都会失败 12 | 13 | ##1.出现一个红色的界面，failed JS bundle 14 | 15 | ![screenshot](http://img1.tbcdn.cn/L1/461/1/a32ef715aec032c8e9f7dc02393070c9ddb2fe39) 16 | 17 | 解决方案: 18 | 19 | 有时候你运行 react-native run-android，发现并不能自动运行 dev server，你可以在当前项目目录中运行如下命令来手动启动 server： 20 | ```shell 21 | $ react-native start 22 | ``` 23 | 本地server指定的8081端口并没有成功接送数据 24 | 25 | adb reverse tcp:8081 tcp:8081 26 | 27 | 可以在chrome浏览器中访问：http://localhost:8081/ 28 | 29 | 在JS-SERVER上看到数据包过来 30 |

error: closed 37 | ``` 38 | 点击手机的物理menu键, 或者摇动手机才会出现Dev settings菜单（这项操作需要在你已经打开的ReactNavtive应用界面操作才有效） 39 | 40 | Dev Settings -> Debug server host for device， 41 | 42 | 填入自己pc电脑上的 IP 地址，需要在同一网段，例如手机和pc都连接到了tplink-wifi-sid上。 43 | 44 | 之后menu-reload js 即可。 45 | 46 | 如果手机和电脑不在同一个网段，或者手机不能访问到，就会出现 47 | Unable to download js bundle的红屏界面 48 | 49 | ##2.可能出现白色的界面 50 | ![图片](http://img4.tbcdn.cn/L1/461/1/9edf84896db6155806115ee309be71ff4b046829) 51 | 解决方案: 52 | 53 | 像MIUI等系统，默认会把那个显示悬浮窗开关给屏蔽关掉【用户可以手动切换】，操作后，重新load即可 54 | 55 | 更常见的搭建问题可以参考下这个：http://www.race604.com/react-native-for-android-start/ 56 | 57 | ##3.invariant Violation:Application 红色屏幕错误 58 |

http://stackoverflow.com/questions/29287987/invariant-violation-application-awesomeproject-has-not-been-registered-when-b 65 | 66 | https://github.com/facebook/react-native/issues/500#issuecomment-111575780 67 | 68 | 2.根据具体错误信息去排查，最后发现我出现这个错误的原因是不小心在文件头部打多了个无效字符，导致无法正确解析下面的代码行。所以只需要把那个无用的代码【影响了语法编译环节】删掉，重新reload -js 即可 69 | 70 | ##4.加载UIExplorerBlock失败 71 | 72 | ![图片](https://github.com/yipengmu/react-native-android-lession/blob/master/pics/Screenshot_2015-09-23-16-41-45.png?raw=true) 73 | 74 | 这是一个官方bug,默认的node_modules里面并没有该组件对应 75 | 76 | https://github.com/facebook/react-devtools/issues/128 77 | 78 | ios之前有这个问题，Android的初期版本貌似也有该类似问题 79 | 80 | ##5. .babelrc.stage文件错误 81 | ```java 82 |

组件使用大写命名 15 | 16 | * 2.对于组件的属性使用小写命名 17 | 18 | * 3.对于style的配置支持按照对象方式去引用，{yourvar.somelable}; 19 | 20 | * 4.也支持两层嵌套style样式，直接写入属性，类似{{}} 21 | 22 | * 5.对于style，React还支持 数组的方式即{[yourvar.somelable1,yourvar.somelable2]} 23 | 24 | ##style样式写法 25 | var styles = StyleSheet.create({ 26 | base: { 27 | width: 38, 28 | height: 38, 29 | }, 30 | background: { 31 |

-------------------------------------------------------------------------------- 1 | #如何封装一个React native for android 的 NativeModule组件 2 | 3 | 4 | ##1.首先需要使用自己的packageManager 5 | 6 | public class YourRnPackage extends MainReactPackage { 7 | @Override 8 | public List createNativeModules(ReactApplicationContext reactContext) { 9 | List modules = super.createNativeModules(reactContext); 10 | //new an Array intstead of abstract List exception 11 | List result = new ArrayList<>(); 12 | result.addAll(modules); 13 | result.add(new YourOpenSomePageModule(reactContext)); 14 | result.add(new YourToastModule(reactContext)); 15 | return result; 16 | } 17 | @Override 18 | public List> createJSModules() { 19 | return Collections.emptyList(); 20 | } 21 | 22 | @Override 23 | public List createViewManagers(ReactApplicationContext reactContext) { 24 | List main = super.createViewManagers(reactContext); 25 | List result = new ArrayList<>(); 26 | result.addAll(main); 27 | result.add(new YourWebviewManager()); 28 | 29 | return result; 30 | 31 | } 32 | } 33 | 34 | 35 | #2.在你的Activitiy或Fragment中对其进行设置 36 | 37 | 38 | public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler { 39 | private ReactInstanceManager mReactInstanceManager; 40 | private ReactRootView mReactRootView; 41 | 42 | @Override 43 | protected void onCreate(Bundle savedInstanceState) { 44 | super.onCreate(savedInstanceState); 45 | mReactRootView = new ReactRootView(this); 46 | 47 | mReactInstanceManager = ReactInstanceManager.builder() 48 | .setApplication(getApplication()) 49 | .setBundleAssetName("index.android.bundle") 50 | .setJSMainModuleName("index.android") 51 | .addPackage(new YourRnPackage()) 52 | .setUseDeveloperSupport(BuildConfig.DEBUG) 53 | .setInitialLifecycleState(LifecycleState.RESUMED) 54 | .build(); 55 | 56 | mReactRootView.startReactApplication(mReactInstanceManager, "YourRnPackage", null); 57 | 58 | setContentView(mReactRootView); 59 | } 60 | 61 | #3.Step by Step: 62 | 63 | 1.Create the ViewManager subclass. 64 | 65 | 2.Annotate the view properties with @UIProp 66 | 67 | 3.Implement the createViewInstance method 68 | 69 | 4.Implement the updateView method 70 | 71 | 5.Register the manager in createViewManagers of the applications package. 72 | 73 | 6.Implement the JavaScript module 74 | 75 | #4.以新增一个自定义Toast为例 76 | 77 | 78 | public class YourToastModule extends ReactContextBaseJavaModule { 79 | private static final String DURATION_SHORT_KEY = "SHORT"; 80 | 81 | private static final String DURATION_LONG_KEY = "LONG"; 82 | 83 | public AliToastModule(ReactApplicationContext reactContext) { 84 | super(reactContext); 85 | } 86 | 87 | @Override 88 | public String getName() { 89 | return "AliToastAndroid"; 90 | } 91 | 92 | @Override 93 | public Map getConstants() { 94 | final Map constants = new HashMap<>(); 95 | //JS端可以使用指定NativeModules对象下的属性 96 | constants.put(DURATION_SHORT_KEY, Toast.LENGTH_SHORT); 97 | constants.put(DURATION_LONG_KEY, Toast.LENGTH_LONG); 98 | return constants; 99 | } 100 | 101 | @ReactMethod 102 | public void show(String message, int duration) { 103 | Toast.makeText(getReactApplicationContext(), message, duration).show(); 104 | } 105 | } 106 | 1.继承自ReactContextBaseJavaModule，实现getName用于js前端调用NativeModules.类A，实现含有@ReactMethod的方法用于前端调用类A的xx方法 107 | 108 | public class YourToastModule extends ReactContextBaseJavaModule { 109 | @ReactMethod 110 | public void show(String message, int duration) { 111 | Toast.makeText(getReactApplicationContext(), message, duration).show(); 112 | } 113 | 2.在你自定义的packManager中增加你的NativeModule, 114 | 115 | @Override 116 | public List createNativeModules(ReactApplicationContext reactContext) { 117 | List modules = super.createNativeModules(reactContext); 118 | //new an Array intstead of abstract List exception 119 | List result = new ArrayList<>(); 120 | result.addAll(modules); 121 | result.add(new YourOpenSomePageModule(reactContext)); 122 | result.add(new YourToastModule(reactContext)); 123 | return result; 124 | } 125 | 126 | 3.这样就可以在前端调用了，代码如下： 127 | 128 | var React = require('react-native'); 129 | var ToastAndroid = React.NativeModules.YourToastModule 130 | ToastAndroid.show('自定义toast 调用成功', ToastAndroid.SHORT); 131 | 132 | #4.最终的自定义组件封装的调用效果如下图所示： 133 | 134 | 1.底部的toast就是通过自定义的React组件显示出来的 135 | 136 | 2.屏幕中的webview也是类似的方法，在JS使用了 137 | 如下代码即可: 138 | 139 | var ToastAndroid = React.NativeModules.MyWebView 140 | 141 | `var AliReactAndroid = React.createClass({})；` 142 | 143 | 146 |

[关于iOS部分可以参考vczero的lession文章](https://github.com/vczero/react-native-lession) 7 | 8 | 9 | > React-Native 是Android端实现实现动态部署的另一种思路，绕过dexLoad【一些现有的Android插件框架】。 10 | 11 | > 是在开发效率和用户体验间做的一种权衡。 12 | 13 | > React-native使用JS开发，开发效率高、发布能力强。 14 | 15 | 16 | * 1、用编辑器打开对应的.js文件，分析代码结构： 17 | 18 | var React = require('react-native'); 19 | 20 | 和Node.js有关，require可以引入其他模块。 21 | 22 | 类似java 的 import com.andorid.xx.Act; 23 | 24 | * 2、定义组件，结构化的代码： 25 | 26 | var { 27 | 28 | AppRegistry, 29 | 30 | StyleSheet, 31 | 32 | Text, 33 | 34 | View, 35 | 36 | } = React; 37 | 38 | * 3、React.createClass里的render方法就是渲染视图用的。return返回的是视图的模板代码。 39 | 40 | * 4、样式表现：那么StyleSheet.create就是干这件事的，只是用JS的自面量表达了css样式。 41 | 42 | * 5、引入css样式： 43 | 44 | 方法1：style={styles.container} 45 | 46 | 方法2：style={{width:20,height:100}} 47 | 48 | * 6、注册View组件，第二个参数为React.createClass创建的 那个var对象 49 | 50 | AppRegistry.registerComponent('aswsome', () => yourVar); 51 | 52 | 53 | #1.环境安装 54 | 1.安装nvm 55 | 56 | * 1.brew install nvm 57 | 58 | 2.nvm 安装最新的 Node.js 4.0 59 | 60 | * nvm install node && nvm alias default node 61 | 62 | 3.安装watchman 和 flow 63 | 64 | * $ brew install watchman 65 | * $ brew install flow 66 | 67 | 并更新brew 68 | 69 | * brew update && brew upgrade 70 | 71 | #2.demo运行 72 | 73 | 首先切换到你想要的目录下，依次执行以下命令 74 | 75 | * $ npm install -g react-native-cli 76 | 77 | * $ react-native init AwesomeProject 78 | 79 | * $ cd AwesomeProject/ 80 | 81 | 运行项目 82 | 83 | * $ react-native run-android 84 | 85 | #3.react-android依赖树 86 | 87 | android-jsc-r174650 88 | 89 | appcompat-v7-23.0.0 90 | 91
