3、java代码
| //加载服务器网页 webView.loadUrl("https://www.baidu.com"); //必须和js同名函数。 webView.registerHandler("submitFromWeb", new BridgeHandler() { @Override public void handler(String data, CallBackFunction function) { String str ="html返回给java的数据:" + data; makeText(MainActivity.this, str, LENGTH_SHORT).show(); Log.i(TAG, "handler = submitFromWeb, data from web = " + data); function.onCallBack( str + ",Java经过处理后："+ str.substring(,)); } }); //模拟用户获取本地位置 User user = new User(); Location location = new Location(); location.address = "xxx"; user.location = location; user.name = "Bruce"; webView.callHandler("functionInJs", new Gson().toJson(user), new CallBackFunction() { @Override public void onCallBack(String data) { makeText(MainActivity.this, "网页在获取你的信息", LENGTH_SHORT).show(); } }); webView.send("hello"); |
| webView.callHandler("functionInJs", "data from Java", new CallBackFunction() { @Override public void onCallBack(String data) { // TODO Auto-generated method stub Log.i(TAG, "reponse data from js " + data); } }); |
js调用
| var str1 = document.getElementById("text1").value; var str2 = document.getElementById("text2").value; //调用本地java方法 window.WebViewJavascriptBridge.callHandler( 'submitFromWeb' , {'param': str} , function(responseData) { document.getElementById("show").innerHTML = "send get responseData from java, data = " + responseData } ); //注册事件监听 document.addEventListener( 'WebViewJavascriptBridgeReady' , function() { callback(WebViewJavascriptBridge) }, false ); //注册回调函数，第一次连接时调用 初始化函数 connectWebViewJavascriptBridge(function(bridge) { bridge.init(function(message, responseCallback) { console.log('JS got a message', message); var data = { 'Javascript Responds': 'Wee!' }; console.log('JS responding with', data); responseCallback(data); }); bridge.registerHandler("functionInJs", function(data, responseCallback) { document.getElementById("show").innerHTML = ("data from Java: = " + data); var responseData = "Javascript Says Right back aka!"; responseCallback(responseData); }); }) |
