The 2.2 version of the Umano Android app features a sexy sliding up draggable panel for the currently playing article. This type of a panel is a common pattern also used in the Google Music app and the Rdio app. This is an open source implementation of this component that you are free to take advantage of in your apps. Umano Team <3 Open Source.

As seen in Umano (http://umanoapp.com):

To use the layout, simply include com.sothree.slidinguppanel.SlidingUpPanelLayout as the Root element in your activity Layout. Layout must have gravity set to either top or bottom. Make sure that it has two children. The first child is your main layout. The second child is your layout for the sliding up panel. Both children should have width and height set to match_parent. For more information, please refer to the sample code.

<com.sothree.slidinguppanel.SlidingUpPanelLayout
    android:id="@+id/sliding_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:text="Main Content"
        android:textSize="16sp" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center|top"
        android:text="The Awesome Sliding Up Panel"
        android:textSize="16sp" />
</com.sothree.slidinguppanel.SlidingUpPanelLayout>

For smooth interaction with the ActionBar, make sure that windowActionBarOverlay is set to true in your styles:

<style name="AppTheme">
    <item name="android:windowActionBarOverlay">true</item>
</style>

You can restrict the drag area of the sliding panel to a specific view by using the setDragView method. Otherwise, the whole panel will be slideable and it will intercept all clicks.

You can change the panel height by using the setPanelHeight method.

You can change the panel shadow by using the setShadowDrawable method. No shadow is displayed by default.

You can disable sliding by using setSlidingEnabled method. This can be useful if you want to show\hide panel only from the code. By default sliding is enabled.

You can set a anchor point in the middle of the screen using setAnchorPoint to allow an intermediate expanded state for the panel (similar to Google Maps).

You can set a PanelSlideListener to monitor events about sliding panes.

You can also make the panel slide from the top by changing the layout_gravity attribute of the layout to top.

This code is heavily based on the opened-sourced SlidingPaneLayout component from the r13 of the Android Support Library. Thanks Android team!
