android - Transparent background in WebView - empty content -

i have problem trying set webview background transparent in application. found lot of similar questions , workarounds how set webview background transparent. popular solution api > 11 is:

// color.transparent or 0x00000000 or simple 0 value webview.setbackgroundcolor(color.transparent);  if (build.version.sdk_int >= 11){    setlayertype(webview.layer_type_software, null); } 

however when add line setlayertype(webview.layer_type_software, null) html content in webview disappear. webview has correct scale (height of content), scroll , reacting on click or tap on (i have image-zoom system on tap). content not showing.

if remove setlayertype() method content shows fine flickering on scroll.

i use android 4.2.2 jb (api 17) , hardwareacceleration whole application set true. html-content body css set

background:transparent; 

also, webview placed inside relative view 2 other textview , relativelayout itselft placed inside scrollview.

i have not found solution case - advises found setlayertype() software.

i had same problem, problem webview inside of scrollview:

<scrollview android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margintop="5dp" >  <linearlayout     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:orientation="vertical" >      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_margin="5dp"         android:text="@string/alert.resume"         android:textcolor="#ff000000"         android:textsize="14sp" />      <webview         android:id="@+id/webview"         android:layout_width="match_parent"         android:layout_height="wrap_content" /> </linearlayout> </scrollview> 

then, removed scrollview , trick works!

<linearlayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" >  <textview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_margin="5dp"     android:text="@string/alert.resume"     android:textcolor="#ff000000"     android:textsize="14sp" />  <webview     android:id="@+id/webview"     android:layout_width="match_parent"     android:layout_height="wrap_content" />  </linearlayout> 

trick usual:

webview text = (webview) view.findviewbyid(r.id.webview);     text.setdrawingcacheenabled(false);     websettings settings = text.getsettings();     settings.setdefaulttextencodingname("utf-8");     text.setbackgroundcolor(color.transparent);         if (build.version.sdk_int >= 11) // android v3.0+             try {             text.setlayertype(view.layer_type_software, null);             } catch (exception e) {             }
