I want to change my WebView\'s background color and font size.
Assuming that you have defined your webview in an XML layout resource you can do the following:
WebView myWebView = (WebView) findViewById(R.id.myWebView);
myWebView.setBackgroundColor(Color.parseColor("#000000"));
myWebView.getSettings.setDefaultFontSize(10);
You may also want to enable javascript and create a simple WebClient to handle page loading
Hope it helps!
