JsBridge库现已迁移至Jitpack，具体使用如下： 1.工程根build.gradle添加jitpack

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

2.模块build.gradle添加依赖

dependencies {
    implementation 'com.github.hjhrq1991:JsBridge:1.1.1'
}

本项目共有两个部分： 1.基于系统的JsBridge； 2.基于Tbs X5内核的JsBridge；

一、JsBridge

基于https://github.com/lzyzsd/JsBridge 优化改进而来的Android JsBridge

优化

1.支持自定义桥名；
2.修复web页未渲染即进行跳转导致Js桥初始化失败的问题；

使用

添加maven依赖

<dependency>
  <groupId>com.hjhrq1991.library</groupId>
  <artifactId>jsbridge</artifactId>
  <version>1.1.0</version>
  <type>pom</type>
</dependency>

添加gradle依赖

compile 'com.hjhrq1991.library:jsbridge:1.1.0'

在你的布局上添加BridgeWebView

<com.hjhrq1991.library.BridgeWebView
 android:id="@+id/webView"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

使用默认桥名或自定义桥名

//description：如需使用自定义桥名，调用以下方法即可，
// 传空或不调用setCustom方法即使用默认桥名。
// 默认桥名：WebViewJavascriptBridge
webView.setCustom("TestJavascriptBridge");

Android上使用方法

注册一个handler方法供Js调用

webView.registerHandler("initSignNetPay", new BridgeHandler() {
   @Override
   public void handler(String data, CallBackFunction function) {
      Log.i(TAG, "回传结果：" + data);
      Toast.makeText(MainActivity.this, data, Toast.LENGTH_SHORT).show();
   }
});

Java里调用Js里的handler方法

webView.callHandler("click1", "success", new CallBackFunction() {
   @Override
   public void onCallBack(String data) {
      Log.i(TAG, "回传结果：" + data);
      Toast.makeText(MainActivity.this, data, Toast.LENGTH_SHORT).show();
   }
});

使用默认handler方法来进行交互

webView.setDefaultHandler(new DefaultHandler());

window.WebViewJavascriptBridge.send(
   data, function(responseData) {
      document.getElementById("show").innerHTML = "repsonseData from java, data = " + responseData
   }
);

JavaScript上使用方法

构建桥连接

var default_data = {
   error: "1"
};

var connectMerchantJSBridge = function (callback) {
   try {
      if (window.WebViewJavascriptBridge) {
      callback(WebViewJavascriptBridge);
   } else {
      document.addEventListener("WebViewJavascriptBridgeReady", function () {
         callback(WebViewJavascriptBridge);
         }, false);
      }
   } catch (ex) { }
};

var cmbMerchantBridge = {
   initSignNet: function (payData,name) {
      if (!payData) {
         payData = default_data;
      }
      connectMerchantJSBridge(function (bridge) {
         if (typeof bridge === "undefined") {
            return;
         }
      bridge.callHandler(name, JSON.stringify(payData));
      });
   },
};

调用Android上的handler方法

function click1(){
   var objData = new datas();
   var payData = objData.click1;
   try {
      cmbMerchantBridge.initSignNet(payData, "initSignNetPay");
   } catch (ex) { }
}

JavaScript里注册一个handler方法供Android调用

/*app native调用本页面方法*/
connectMerchantJSBridge(function(bridge) {
   bridge.init(function(message, responseCallback) {

});

bridge.registerHandler("click1", function(data, responseCallback) {
   responseCallback("receive click1");
   //可以在下面执行操作
   });
})

window.cmbMerchantBridge = cmbMerchantBridge;

setWebViewClient

Js桥的处理在WebViewClient里进行，因此使用setWebViewClient()方法会导致Js桥失效 因此提供新的API方法进行回调

        webView.setBridgeWebViewClientListener(new SimpleBridgeWebViewClientListener() {
        
        });

当然你也可以直接new BridgeWebViewClientListener()

        webView.setBridgeWebViewClientListener(new BridgeWebViewClientListener() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                return false;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {

            }

            @Override
            public void onPageFinished(WebView view, String url) {

            }

            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

            }

            @Override
            public void onLoadResource(WebView view, String url) {

            }

            @Override
            public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
                return null;
            }

            @Override
            public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
                return null;
            }

            @Override
            public boolean onTooManyRedirects(WebView view, Message cancelMsg, Message continueMsg) {
                return false;
            }

            @Override
            public boolean onFormResubmission(WebView view, Message dontResend, Message resend) {
                return false;
            }

            @Override
            public void doUpdateVisitedHistory(WebView view, String url, boolean isReload) {

            }

            @Override
            public boolean onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
                return false;
            }

            @Override
            public boolean onReceivedClientCertRequest(WebView view, ClientCertRequest request) {
                return false;
            }

            @Override
            public boolean onReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, String host, String realm) {
                return false;
            }

            @Override
            public boolean shouldOverrideKeyEvent(WebView view, KeyEvent event) {
                return false;
            }

            @Override
            public boolean onUnhandledKeyEvent(WebView view, KeyEvent event) {
                return false;
            }

            @Override
            public void onScaleChanged(WebView view, float oldScale, float newScale) {

            }

            @Override
            public void onReceivedLoginRequest(WebView view, String realm, String account, String args) {

            }

            @Override
            public void onPageCommitVisible(WebView view, String url) {

            }

            @Override
            public boolean onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
                return false;
            }

            @Override
            public void onReceivedHttpError(WebView view, WebResourceRequest request, WebResourceResponse errorResponse) {

            }
        });

混淆

从1.1.7版本开始需要增加混淆规则

-keep public class com.hjhrq1991.library.Message{*;}
