I want to change my WebView
\'s background color and font size.
You could call some javascript that would modify the CSS of the loaded page.
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!
I would think you can't - unless you control the html data displayed.
The font and background are controlled by the html data feed to the Webview and not the Webview itself.
