Hybird App
Hybrid 开发：JsBridge - Web 和客户端的桥
Hybrid开发中，web页面往往会跟native进行交互，而JSBridge就是web页面和native进行通信的桥梁，通过JSBridge可以实现web调用native的方法，native可以通过webview.loadUrl之类的方法，将javascript:xxx代码放在页面执行，这有点类似在浏览器地址栏直接输入：javascript:xxx
web和native进行通信，JsBridge的多种形式
①JavaScriptInterface
// Android java代码
mWebView.addJavascriptInterface(new Class(), 'android');
public class Class(){
@JavascriptInterface
public void method(){
}
}
// js 代码
window.android.method();
②改写浏览器原有对象
通过修改原来浏览器的window某些方法，然后拦截固定规则的参数，然后分发给Java对应的方法去处理。这里常用的是以下四个方法：
- alert，可以被webview的onJsAlert监听
- confirm，可以被webview的onJsConfirm监听
- console.log，可以被webview的onConsoleMessage监听
- prompt，可以被webview的onJsPrompt监听
AgentWeb开源框架的基本使用
Android
if(mAgentWeb!=null){
//注入对象
mAgentWeb.getJsInterfaceHolder().addJavaObject("android",new AndroidInterface(mAgentWeb,this.getActivity()));
}
mAgentWeb.getJsAccessEntrace().quickCallJs("callByAndroidParam","Hello ! Agentweb");
mAgentWeb.getJsAccessEntrace().quickCallJs("callByAndroidMoreParams", new ValueCallback<String>() {
@Override
public void onReceiveValue(String value) {
Log.i("Info","value:"+value);
}
},getJson(),"say:", " Hello! Agentweb");
private String getJson(){
String result="";
try {
JSONObject mJSONObject=new JSONObject();
mJSONObject.put("id",1);
mJSONObject.put("name","Agentweb");
mJSONObject.put("age",18);
result= mJSONObject.toString();
}catch (Exception e){
}
return result;
}
