根據WebView里面的鏈接字符串跳轉Activity

?

activityBaseWebAddWebView.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {if (url.startsWith(Url.urlHost + "/weixin/getJsp?url=wechatweb/business-member")) {//包含這個Url字符就跳轉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);// 這段js函數的功能就是，遍歷所有的img節點，并添加onclick函數，在還是執行的時候調用本地接口傳遞url過去view.loadUrl(CommonString.imgClickWithShowClass);} });

1、webview與原生交互——根據js方法跳轉到Activity

?

activityBaseWebAddWebView.addJavascriptInterface(new WebViewJavaScriptFunction() {@Overridepublic void onJsFunctionCalled(String tag) {// TODO Auto-generated method stub}@JavascriptInterfacepublic void goToBusinessChatRoom() { // window.yxbl_app.toChat() //js調用android源碼方法,發起環信聊天if (TextUtil.isEmpty(groupid)){Toast.makeText(getApplicationContext(), "該群不存在", Toast.LENGTH_SHORT).show();return;}gotoliaotian();}@JavascriptInterfacepublic void toCompanyDetail(String epId, String accessPath, String a) {//網頁定義的方法名相同即可，同時可以傳參數 // window.yxbl_app.toCompanyDetail() //js調用android源碼方法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調用android源碼方法 // 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頁面跳轉投資列表intent.setClass(BusinessDetailWebActivity.this, GongXuActivity.class);startActivity(intent.putExtra("id", id));}}, CommonString.js2Android);}

2、原生與webview交互：changeColor是js方法，viewColor是參數

?

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

?

附：自定義接口
