Android WebView background color

Try using synopsis.getSettings();

WebView synopsis;
synopsis=(WebView)findViewById(R.id.synopsis);
synopsis.setBackgroundColor(Color.TRANSPARENT);

try below code hope use full for you:-

webview.setBackgroundColor(Color.parseColor("#919191"));

grey code : #919191

You must put this in the XML code :

android:background="@android:color/transparent"

for your web view like this for example :

<WebView
    android:id="@+id/MyWebView"
    android:layout_width="fill_parent"
    android:layout_height="62dp"
    android:background="@android:color/transparent"
    android:scrollbars="none" />

and after this you must go to Java code and write this before loadUrl :

yourWebView.setBackgroundColor(Color.TRANSPARENT);

What I do is

 synopsis.setBackgroundColor(0);

Hope it helps!
