I struggle with this every time I work on a project. I am not entirely sure what the standard conventions are for creating view ids. I usually use something like view_more_buttonbut then if we have, let's say, multiple dialogs with a view more button then I'll start doingview_more_button_dialog1and from there it just spirals downward.Any suggestions?
How to format Android view IDs
android;coding standards;conventions
I usually prefix resource IDs with the component they belong to. Note that I say resource IDs and not View IDs because this applies to other resources too (String for example). Specifically for views, I further add the view type after the component prefix.Here's a concrete example:login_button_done (View ID)login_ok (String resource)login_forgot_password (String resource)dialog_button_view_more (View ID)dialog_label_warning (View ID)One advantage of this approach is it makes it easier for IDE auto-complete. The downside is more keystrokes at the time of creating the views/String resources.I have seen developers use a convention that puts the prefixes in the other order (i.e., viewtype_component_id). You should pick whatever suits your needs the best and just remember to stick to it throughout.Not directly related to the question - but for some of my larger applications where the number of resources (especially strings) is very large, I also prefer to split up the strings into multiple files by component. For example, I'd have strings_login.xml, strings_settings.xml etc.Specifically for dialogs, your view hierarchy would rarely (never ??) contain two dialogs simultaneously, so it is okay to re-use view IDs. In fact, I do sometimes create a few generic View IDs for this purpose.
