Answer 1

A WebView has a default background color of white, drawn in front of any drawables. You’ll need to use the following code to make it transparent:

WebView webview = (WebView)findViewById(R.id.wv);        
        webview.setBackgroundColor(0);

Then apply a gradient background as follows:

Create a file called gradient-bg.xml in your /res/drawable-mdpi folder.

Add:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
       android:shape="rectangle">
    <gradient 
            android:startColor="#FFFFFF" 
            android:endColor="#000000"
            android:angle="90"
            />
</shape>

Then in your layout files you can add the drawable to any view or layout via the background property:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/gradient-bg"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
</LinearLayout>
