2 Levels of Category

Hi,

I am not very experienced with programming Roku channels. I created 2 channels with a template from the ROKU website (Video Player Example Application), but now I have to create another channel that requires 2 levels + the level where all the videos are.

So here is what the channel should look like:



I have 3 XML files
1. Level would be for Category 1, Category 2
2. Level would be for Category 1-1, Category 2-1,...
3. Level would be for the actual content, the videos.

The first Level XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<categories>
<category title="Truths That Transform"
description="A TV Program produced by D James Kennedy Ministries"
sd_img="http://djkm-roku.s3.amazonaws.com/toplevelposters/TTT-TopLevelCategory_224x258.jpg"
hd_img="http://djkm-roku.s3.amazonaws.com/toplevelposters/TTT-TopLevelCategory_304x237.jpg">
<categoryLeaf title="Program" description="Truths That Transform"
feed="http://djkm-roku.s3.amazonaws.com/ttt/xml/ttt-year.xml" />
</category>
<category title="Kennedy Classics"
description="A TV Program produced by D James Kennedy Ministries"
sd_img="http://djkm-roku.s3.amazonaws.com/toplevelposters/KC-TopLevelCategory_224x158.jpg"
hd_img="http://djkm-roku.s3.amazonaws.com/toplevelposters/KC-TopLevelCategory_304x237.jpg">
<categoryLeaf title="Program" description="Kennedy Classics"
feed="http://djkm-roku.s3.amazonaws.com/kc/xml/kc-year.xml" />
</category>

</categories>



2. Level XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<categories>

<category title="Kennedy Classics 2015"

sd_img="http://s3.amazonaws.com/djkm-roku/kc/poster/SD_CategoryPoster-2015_285x145.jpg"
hd_img="http://s3.amazonaws.com/djkm-roku/kc/poster/HD_CategoryPoster-2015_385x218.jpg">
<categoryLeaf title="2015" description="Kennedy Classics 2015"
feed="http://djkm-roku.s3.amazonaws.com/ttt/xml/ttt-program_2015.xml" />
</category>

</categories>



3. Level XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<feed>
<!-- resultLength indicates the total number of results for this feed -->
<resultLength>45</resultLength>
<!-- endIndix indicates the number of results for this *paged* section of
the feed -->

<synopsis>We live in a time of vast government overreach in part because Christians have forgotten the truth and bought into the lies of humanism. Rather than holding a biblical view of government, too many Christians have stood with their neighbors in calling for a government savior. Dr. D. James Kennedy was on the forefront of warning Christians to beware of putting government in God’s place.</synopsis>

If I use Level 2 as my started level everything works fine. If I add level 1 on top of it, I can display level 2, but after that nothing happens anymore. I assume that the code is expecting the feed after the first category. So how can I change the code that I can go from 1 Category to the 2 Category and then to the feed?

Thanks for your help

Re: 2 Levels of Category

The Roku SDK videoplayer example does not handle a three-level hierarchy. However, the NewVideoPlayer example does. See this post for details: http://forums.roku.com/viewtopic.php?f=34&t=91672&p=516080

To get your channel working, put the following in the pkg:/xml/categories.xml file:

Then go to the source/UITheme.brs file to specify the locations of your artwork/logos, etc.

Thank you so much belltown. your code was so easy to adopt and apply to our purpose it was unbelievable.
I really appreciate what you have done, not only for the ROKU community, but even more for my sanity ... HaHa.
