Java Question R.Layout and findViewById(R.id.surface_view)

[moster67]

I am gradually writing a wrapper for the Vitamio-plugin. See my post here: http://www.b4x.com/forum/additional-libraries-classes-official-updates/19329-vitamiob4a-b4a-wrapper-vitamio-plugin-advanced-videoview-library.html

Most stuff works but I have a problem with setting the video-size. From the sources I am using (link for download: http://files.cnblogs.com/over140/2012/5/Vitamio-Demo2012-5-22.zip) and when compiling the project (make sure to use VideoViewDemo - you can comment out the other project), the resulting app works nicely and in particular change of video-size (double-tapping on screen).

In my own B4A sample-project (see my VitamioB4A post), I can get some results (in Panel long-click event) but it is only the view itself which changes size and not the playing video contrary to the sample-app generated from the sources I am using.

I believe it has something to with the surface_view. In the sources (and the app) which are working, there are two lines as follows:

setContentView(R.layout.videoview);
mVideoView  = (VideoView) findViewById(R.id.surface_view);

//for my project, I had to change it into:

vitamioExt = (VideoView) findViewById(R.id.surface_view)

I have not been able to implement above code (my knowledge of Java is very poor) and I believe said code might be the reason why the change of video-size does not work. Maybe it is not possible anyhow to use said code in B4A-wrappers since I believe the xml-layout is only created during compilation although I am not sure. If this is the case, what can I do overcome that problem?

Note: in the API, there is also also an event called "OnVideoSizeChangedListener" but it seems it is not used in the sources I am using so it is probably of no importance.

As mentioned, you can find my eclipse-sources in the other post. If some of you experts would like to take a look and see if there is something obvious which is missing or which I am doing wrong, I would really be grateful. If there is an error or something I have not implemented properly, you will probably find in the wrapper-source (Eclipse). However, maybe I am not using the wrapper correctly in the B4A-project. I am not 100% sure.

In a certain way, I am already pleased with the wrapper-library at is current state but still it would be a pity if I couldn't implement the change of video-size since it is actually working in the other sample-project mentioned above. It would also be another benefit of this library since the standard Android video-view does not support video-sizing (only original size).

Thanks.

Here's an example of how to access the R Resources class of a B4A application from within a library:

String resourceName="surface_view";
int resourceId = BA.applicationContext.getResources().getIdentifier(resourceName, "id", BA.packageName);
vitamioExt = (VideoView) findViewById(resourceId)

Thanks Martin.

I had seen that code earlier on the forum but I was unsure how to implement it.

In either case, I got the video-size problem sorted. The library is OK and doesn't need those two lines of code mentioned in my first post. At the end, the problem was in B4A. I had to remove the view and then re-add it in order to get it working. :sign0161:

Thanks once again for your help.

Hello Martin,

I have seen and tested your code to access R resources in B4A, I have tried it and always return 0.

There is some additional definition that must be made for the implementation of this instruction and to be able to access this resource?
