web - android 混合开发

1. 集成简单: JCenter -> compile 'com.mainli:webhybrid:1.0.0'

2. 支持配置自定义协议,使用正则截取参数放入HashMap<String, String>

3. js调用java两种方式,如:

	function btn3() {
		prompt("client://name=按钮3&alert=按钮3弹出&call1=java2js");
	}
	function btn4() {
		window.location.href = "http://www.baidu.com?client://name=按钮4&alert=按钮4弹出来的&call=java2js";
	}

一、js调用java层两种方式:

1.直接在URL后面加上自定义协议
2.在js中使用Prompt提示框

二、java层集成:

1. 集成步骤: //设置WebView属性，能够执行Javascript脚本 WebSettings settings = webView.getSettings(); settings.setJavaScriptEnabled(true); //实例化拦截器 并加入分发管理器 Interceptor interceptor = new Interceptor(this, new DistributManage() { @Override public JSAction onIntercept(HashMap<String, String> param) { String name = param.get("name"); JSAction jsAction = null; switch (name) { case "按钮1": jsAction = new JSPrint1(); break; case "按钮2": jsAction = new JSPrint2(); break; } return jsAction; } });//默认协议开头client:// webView.setWebChromeClient(new HybridWebChromeClient(interceptor)); webView.setWebViewClient(new HybridWebClient(interceptor));

2. 自定义待分发JsAction 如:
   public class JSPrint1 implements JSAction { @Override public void executeJS(Activity activity, WebView webView, HashMap<String, String> param) {//运行JS请求 System.out.println("Js传来参数" + param); String call = param.get("cal"); if (TextUtils.isEmpty(call)) call = "call"; Toast.makeText(activity, call, Toast.LENGTH_SHORT).show(); JSCall.executeJavaScript(webView, call, param.get("alert"));//执行回调JS代码如果需要 }

        @Override
        public boolean needJSBeforeRun(HashMap<String, String> param) {//判断是否需要执行JS回调之前时候执行一个回调 如获取用户信息前需要登录的操作
            return false;
        }
    }
   

二、自定义协议头:

默认协议为: client://key1="参数1"&key2="参数2"&key3="参数3"&key4="参数4"......

修改协议头在实例化InterceptorConfig时传入。

例:
Interceptor interceptor = new Interceptor(this, new DistributManage() {
        @Override
        public JSAction onIntercept(HashMap<String, String> param) {
                    return null;
        }
},new InterceptorConfig("xxx://"));

InterceptorConfig默认两个参数:

    //自定义请求协议头部
    public String mAgreementHead = "client://";
    //截取参数正则表达式(建议不修改)
    public String mAgreementParamRegular = String.format("(?:%s|&)([^=^&]+)=([^&]*)", mAgreementHead);
