这段代码给我提供了页面的html文档，我想打印json。
WebViewClient yourWebClient = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
@Override
public void onPageFinished(WebView view, String url) {
wb.loadUrl("javascript:HtmlViewer.showHTML" +
"('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
}
};
wb = (WebView) findViewById(R.id.webview);
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setSupportZoom(true);
wb.getSettings().setBuiltInZoomControls(true);
wb.setWebViewClient(yourWebClient);
wb.loadUrl("http://pqrs.abcde.com/facebook");
wb.addJavascriptInterface(new MyJavaScriptInterface(this), "HtmlViewer");
