Android WebView style background-color:transparent-第2页回答

I'm struggling to create a WebView with transparent background.

webView.setBackgroundColor(0x00FFFFFF);
webView.setBackgroundDrawable(myDrawable);

Then I load a html page with

<body style="background-color:transparent;" ...

The background color of the WebView is transparent but as soon as the page is loaded, it's overwritten by a black background from the html page. This only happens on android 2.2, it works on android 2.1.

So is there something to add in the html page code to make it really transparent ?

Use this

WebView myWebView = (WebView) findViewById(R.id.my_web);

myWebView.setBackgroundColor(0);

Following code work for me, though i have multiple webviews and scrolling between them is bit sluggish.

v.setBackgroundColor(Color.TRANSPARENT);
Paint p = new Paint();
v.setLayerType(LAYER_TYPE_SOFTWARE, p);

webView.setBackgroundColor(0x00000000);
webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

this will definitely work.. set background in XML with Editbackground. Now that background will be shown

This worked for me. try setting the background color after the data is loaded. for that setWebViewClient on your webview object like:

    webView.setWebViewClient(new WebViewClient(){

        @Override
        public void onPageFinished(WebView view, String url)
        {
            super.onPageFinished(view, url);
            webView.setBackgroundColor(Color.BLACK);
        }
    });

set the bg after loading the html(from quick tests it seems loading the html resets the bg color.. this is for 2.3).

if you're loading the html from data you already got, just doing a .postDelayed in which you just set the bg(to for example transparent) is enough..

If nothing helps, then most probably you have fixed sized webView, change the width and height to wrap_content or match_parent, it should work. That worked for me when I tried to load a Gif.
