web页面打印(web页面打印控件)

ps：因为我的内容是html js一起填充，所以不能直接打印

按照以下三个步骤完成

1.

final class InJavaScriptLocalObj {	@JavascriptInterface 	   public void showSource(String html) {		Log.d("HTML", html); 		        }		}

2.

webView.addJavascriptInterface(new InJavaScriptLocalObj(), "local_obj");

3.

webView.setWebViewClient(new WebViewClient() {@Override 	public void onPageFinished(WebView view, String url) { 	  super.onPageFinished(view, url);  // view.loadUrl("javascript:alert(document.getElementsByTagName('html')[0].innerHTML)");  view.loadUrl("javascript:window.local_obj.showSource('' document.getElementsByTagName('html')[0].innerHTML '');");}
