Hi,

I would like to make a custom controller in Android, which looks like this example:

XML

<control>
    <input>
        <name></name>
        <value></value>
    </input>
    <output>
        <name></name>
        <value></value>
    </output>
</control>

How can I read parameters in code?

Thanks

I would start by reading Custom components (Developers Guide)[^] and then take a look at UI elements XML[^] which fills in the gaps.

Thank you for your reply.
I know how to do own control with attributes, this is not what I need now.
My problem is how to parse / find parameters as xml tag.
Or do you have suggestion how to do it different way?

did you click on the UI elements XML link ? I'm sure that answers the problem.

Yes, of course I clicked. But still, its about attributes in xml, but I nedded parameters (tags) and that is why I had to use SAX parser.

Read about parsing XML in Android:
http://www.ibm.com/developerworks/opensource/library/x-android/[^],
http://www.ibm.com/developerworks/opensource/library/x-androidxml/index.html?ca=drs-[^],
http://www.androidpeople.com/android-xml-parsing-tutorial-using-saxparser[^],
http://www.androidpeople.com/android-xml-parsing-tutorial-%E2%80%93-using-domparser[^].

Basically, you can either take SAX approach or DOM approach. See:
SAX, "Simple API for XML": http://en.wikipedia.org/wiki/Simple_API_for_XML[^],
DOM: http://en.wikipedia.org/wiki/Document_Object_Model[^].

As your XML is quite small, I would recommend simpler DOM approach.
