SlidingPaneLayout background color

Question

I am using SlidingUpPanel. Everything works great. :) What I would like to achieve is change the background color of the panel in the image to transparent so that it shows the part of the image behind it. I tried setting background color of the SLidingPaneLayout to transparent but it doesn't work. When I change the color to something else like red, it shows red but doesn't happen the same with transparent.

I also tried setting window background to transparent but it leaves a black background.

Window window = this.getWindow();
window.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

Please help.

Answer 1

Try to add this line to your SlidingPanel:

sothree:umanoOverlay="true"

And add transparent to the background in the xml:

<com.app.custom.FrameLayoutWithBluredBackground
   android:id="@+id/dragView"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:clickable="true"
   android:focusable="false"
   blurView:blurRadius="20"
   android:background="@android:color/transparent"
