WebView技巧

WebView启用相关配置

   wv = (WebView) findViewById(R.id.article_webwiew);
wv.getSettings().setSupportMultipleWindows(true);
wv.getSettings().setJavaScriptEnabled(true);
wv.setWebViewClient(new WebViewClient());
wv.setWebChromeClient(new WebChromeClient());
wv.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
wv.getSettings().setAllowFileAccess(true);//允许读取文件
wv.getSettings().setAllowContentAccess(true);
wv.getSettings().setSupportZoom(false);//禁止缩放
wv.getSettings().setDomStorageEnabled(true);//开启本地数据库储存
wv.getSettings().setDatabaseEnabled(true);

WebView 缩放

wv.getSettings().setSupportZoom(true);//禁止缩放
wv.getSettings().setBuiltInZoomControls(true);
wv.getSettings().setDisplayZoomControls(true);
wv.setInitialScale(100); //缩放比例

WebView JSON数据替换为String

webView = (WebView) findViewById(R.id.bbs_webview);  
webView.getSettings().setJavaScriptEnabled(true);  
special_content = special_content.replaceAll("&", "");  
special_content = special_content.replaceAll(""", """);  
special_content = special_content.replaceAll("<", "<");  
special_content = special_content.replaceAll(">", ">");  
special_content = special_content.replaceAll("\n", "<br>");//换行  
special_content = special_content.replaceAll("<img", "<img width="100%"");//图片不超出屏幕  
webView.loadDataWithBaseURL(null, special_content, "text/html", "utf-8", null);   //加载html源码
