Force fading edge on TextView
<p>I have TextView inside FrameLayout and I want to draw fading edge of FrameLayout over TextView to indicate that text may be expanded vertically.
How to draw fading enge of FrameLayout?</p>

<p>Fragment of layout:</p>

<pre><code>&lt;FrameLayout
    android:layout_width="fill_parent" 
    android:layout_height="@dimen/list_item_collapsed"
&gt;
    &lt;TextView
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
    /&gt;
&lt;/FrameLayout&gt;
</code></pre>
