Android WebView style background-color:transparent ignored on android 2.2
This worked for me,
mWebView.setBackgroundColor(Color.TRANSPARENT);
At the bottom of this earlier mentioned issue there is an solution.It's a combination of 2 solutions.
webView.setBackgroundColor(Color.TRANSPARENT);webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);When adding this code to the WebViewer after loading the url, it works (API 11+).
It even works when hardeware acceleration is ON
I had the same issue with 2.2 and also in 2.3. I solved the problem by giving the alpa value in html not in android. I tried many things and what I found out is setBackgroundColor(); color doesnt work with alpha value. webView.setBackgroundColor(Color.argb(128, 0, 0, 0)); will not work.
so here is my solution, worked for me.
String webData = StringHelper.addSlashes("<!DOCTYPE html><head> <meta http-equiv=\"Content-Type\" " + "content=\"text/html; charset=utf-8\"> </head><body><div style=\"background-color: rgba(10,10,10,0.5); " + "padding: 20px; height: 260px; border-radius: 8px;\"> $$$ Content Goes Here ! $$$ </div> </body></html>");And in Java,
webView = (WebView) findViewById(R.id.webview); webView.setBackgroundColor(0); webView.loadData(webData, "text/html", "UTF-8");And here is the Output screenshot below.
