android 基于jsBridge实现js交互时对webview监听onPageStarted及onPageFinished

最近Android项目中需要实现webview与js交互，网上推荐的框架是https://github.com/lzyzsd/JsBridge
基于jsbridge调用实现webview与js交互具体用法作者已详细讲解不再解释，本文主要说在实现webview交互后想监听webview的onPageStarted及onPageFinished实现加载动画的坑。
js交互代码

//  JS调JAVA   重点： Java端需要注册事件监听，即webView.registerHandler()。PHP需要做的工作：重写接口回调，
        webView.registerHandler("goodsInfo", new BridgeHandler() {
            @Override
            public void handler(String data, CallBackFunction function) {
                Logger.json(data);
                Map<String, Object> map = JSONFormat.jsonToMap(data);
                String param = (String) map.get("goodsid");
                aCache.put("goodsname", map.get("goodsname") + "");
                aCache.put("goodsimg", "http://" + URLutile.PHPURL + "/" + map.get("goodsimg") + "");
                Intent intent = new Intent(HelpMallActivity.this, GoodsDetailActivity.class);
                intent.putExtra("param", param);
                startActivity(intent);

            }

        });

交互后重点是监听webview的onPageStarted及onPageFinished实现加载动画
用的代码是

webView.setWebViewClient(new WebViewClient()
        {
            @Override
            public void onPageFinished(WebView view, String url)
            {
                super.onPageFinished(view, url);
                stopMyDialog();
            }
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon)
            {

                super.onPageStarted(view, url, favicon);
                startMyDialog();
            }
        });

后发现js交互不能用了，开始查看jsBridge源码发现BridgeWebViewClient中已经重新写了onPageStarted及onPageFinished的监听，两个冲突了，js交互也就不能用了。

解决办法
新建一个WebViewClient继承BridgeWebViewClient

package com.yskj.lsk.widget.circleimageview;

import android.content.Context;
import android.graphics.Bitmap;
import android.webkit.WebView;

import com.github.lzyzsd.jsbridge.BridgeWebView;
import com.github.lzyzsd.jsbridge.BridgeWebViewClient;
import com.yskj.lsk.util.MyLoading;

/**
 * Created by jianghe on 2016/11/18 0018.
 */
public class LocalWebViewClient extends BridgeWebViewClient {
    private MyLoading myloading;
    private Context context;

    public LocalWebViewClient(BridgeWebView webView) {
        super(webView);
    }
    public LocalWebViewClient(BridgeWebView webView, Context context){
        super(webView);
        this.context = context;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
        startMyDialog();
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        stopMyDialog();
    }

    /**
    * dialog 启动
    */
    public void startMyDialog() {
        if (myloading == null) {
            myloading = MyLoading.createLoadingDialog(context);
        }
        if (!myloading.isShowing()) {
            myloading.show();
        }
    }

    /**
     * dialog 销毁
     */
    public void stopMyDialog() {
        if (myloading != null) {
            if (myloading.isShowing()){
                myloading.dismiss();
            }
            myloading = null;
        }
    }
}

再在web中调用
//监听加载开始和加载结束
webView.setWebViewClient(new LocalWebViewClient(webView,context));
后一切正常
