    <ol> <li><p>@+id/.... creates an id value that lives within the applications namespace. Contrast this with @android:id/.... which lives in the android namespace.</p></li> <li><p>When you set the id in code and add the view element to the layout it will then become available to access through the code. You won't be able to reference it from the xml </p></li> <li><p>Not sure you want to be using random to generate your ids? think sequential would be better but even then what is the point of a random id? How do you know which view you are referring to?</p></li> <li><p>Definitely use the tag option and look to use the ViewHolder pattern for smoother list scrolling. You could add the id to the view holder class if you need access to it but it would be available anyway through the data set being used to populate the list. A quick search will give you plenty of examples for this.</p></li> </ol>

    1. COHi! the basic idea behind the random / increasing ids was to avoid somehow to add duplicate ids without manually looking up all the fix ids in the layout xml, and checking, if the new id is already among them. Thank you for the answer, but could you please tell me, how these ids are generated? As far as i can tell, like my second option: the IDE chooses a random number and adds one with each new id.

    2. COIf you don't add an id then you won't be able to access the view by id. Have you looked at adding a tag to the view and then accessing by a tag? Is the option of iterating through the child views a possible solution to what you are trying to achieve? Generally you only need an id if you need to access a specific view in the hierarchy. If the view is a list or grid type parent then you will access the child views through an adapter class which will handle setting and retrieving the view in question. Maybe further information regarding the context of the question would help?

    3. COI have no specific in mind, what i'm trying to achieve. Truth is, that the question came up, when i wrote a wrapper class for RadioButtons, to create something similar like a RadioGroup without being a View, just handling the buttons check state. This class handles, selects and deselects the RadioButtons by id, and when i started testing it with larger amount of RadioButtons, i needed to generate ids dinamically. Then i started to wonder about these questions. Thanks for your help again, i think the most important to know was, that runtime generated ids are accessible by findViewById().

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
