    android:orientation="vertical"
    tools:context=".ui.WebViewActivity">

    <android.support.v4.widget.ContentLoadingProgressBar
        style="?android:attr/progressBarStyleHorizontal"
        android:id="@+id/web_view_load_progress"
        android:layout_width="match_parent"
        android:layout_height="2dp"
        android:visibility="invisible"
        android:progressDrawable="@drawable/webview_load_progress_drawable"
        />

    <WebView
        android:id="@+id/common_web_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

activity使用

 mWebView.getSettings().setJavaScriptEnabled(true); //设置允许执行js脚本
//        mWebView.addJavascriptInterface(new AndroidH5(this, mWebView), "AndroidH5");
        mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);//进度条不占位
        mWebView.getSettings().setAppCacheEnabled(true); //设置使用浏览器缓存
        mWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT); //设置换成模式
//    webUrl = "http://172.168.2.3:8010/broker/lp_info.html?buildingid=7118&from=android";
        mWebView.loadUrl(urlGenerate(webUrl));
        mWebView.setWebChromeClient(new WebChromeClient() {//webview 提供的一个专门处理进度的方法
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                progressBar.setProgress(newProgress);

                super.onProgressChanged(view, newProgress);
            }

        mWebView.setWebViewClient(new WebViewClient(){//webView 提供加载地址的方法
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {

                return true;//super.shouldOverrideUrlLoading(view, url);
            }

		
/**
