根据WebView里面的链接字符串跳转Activity

 

activityBaseWebAddWebView.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {if (url.startsWith(Url.urlHost + "/weixin/getJsp?url=wechatweb/business-member")) {//包含这个Url字符就跳转startActivity(new Intent(BusinessDetailWebActivity.this, My_BusMemberActivity.class).putExtra("url", url));}else if (url.startsWith(Url.urlHost + "/weixin/getJsp?url=wechatweb/crowdfund-info")) {startActivity(new Intent(BusinessDetailWebActivity.this, BusinessCrowdFoundingWebActivity.class).putExtra("url", url));} else if(url.startsWith("http://images.yxtribe.com/upload/images/business/")) {Intent webIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));startActivity(webIntent);} else {url += "&appFlg=1";view.loadUrl(url);}return true;}@Overridepublic void onPageStarted(WebView view, String url, Bitmap favicon) {view.getSettings().setJavaScriptEnabled(true);}@Overridepublic void onPageFinished(WebView view, String url) {view.getSettings().setJavaScriptEnabled(true);super.onPageFinished(view, url);// 这段js函数的功能就是，遍历所有的img节点，并添加onclick函数，在还是执行的时候调用本地接口传递url过去view.loadUrl(CommonString.imgClickWithShowClass);}
});

1、webview与原生交互——根据js方法跳转到Activity

 

        activityBaseWebAddWebView.addJavascriptInterface(new WebViewJavaScriptFunction() {@Overridepublic void onJsFunctionCalled(String tag) {// TODO Auto-generated method stub}@JavascriptInterfacepublic void goToBusinessChatRoom() {
//            window.yxbl_app.toChat()  //js调用android源码方法,发起环信聊天if (TextUtil.isEmpty(groupid)){Toast.makeText(getApplicationContext(), "该群不存在", Toast.LENGTH_SHORT).show();return;}gotoliaotian();}@JavascriptInterfacepublic void toCompanyDetail(String epId, String accessPath, String a) {//网页定义的方法名相同即可，同时可以传参数
//            window.yxbl_app.toCompanyDetail()  //js调用android源码方法Intent intent = new Intent(BusinessDetailWebActivity.this, CompanyDetailWebActivity.class);intent.putExtra("epId", Integer.parseInt(epId));intent.putExtra("accessPath", accessPath);startActivity(intent);}@JavascriptInterfacepublic void BusinessVisit(int aid,String aname,String ac,String ap) {
//                Log.v("Lgq","newo[==="+aname);
//            window.yxbl_app.toCompanyDetail()  //js调用android源码方法
//                Intent intent = new Intent(BusinessDetailWebActivity.this, CompanyDetailWebActivity.class);
//                intent.putExtra("epId", Integer.parseInt(epId));
//                intent.putExtra("accessPath", accessPath);
//                startActivity(intent);}@JavascriptInterfacepublic void openImage(String imageUrls, String img) {Intent intent = new Intent();intent.putExtra("imageUrls", imageUrls);intent.putExtra("curImageUrl", img);Log.v("lgq","tophoto===== "+img+".....  "+ imageUrls);intent.setClass(BusinessDetailWebActivity.this, PhotoBrowserActivity.class);startActivity(intent);}@JavascriptInterfacepublic void gotoGongxu() {Intent intent = new Intent();intent.setClass(BusinessDetailWebActivity.this, GongXuActivity.class);startActivity(intent);}@JavascriptInterfacepublic void gotoInvestment(String id) {Intent intent = new Intent();// web页面跳转投资列表intent.setClass(BusinessDetailWebActivity.this, GongXuActivity.class);startActivity(intent.putExtra("id", id));}}, CommonString.js2Android);}

 

2、原生与webview交互：changeColor是js方法，viewColor是参数

 

activityBaseWebAddWebView.loadUrl("javascript:changeColor('" + viewColor + "')");

 

附：自定义接口

public interface WebViewJavaScriptFunction {void onJsFunctionCalled(String tag);
