Question

In general, I want to know how should I inflate custom layout defined in XML at runtime without having a redundant layout in my views hierarchy.

Now, in particular:

I have a custom layout which is declared in an xml, my_relative_layout.xml and its root element is a RelativeLayout.
I have also defined a class which extends RelativeLayout called MyRelativeLayout.java.

How can I inflate my_relative_layout.xml in my MyRelativeLayout.java in a way that I won’t have a redundant RelativeLayout in the hierarchy.

I tried using <merge> – it caused that all the root element attributes in my_relative_layout.xml didn’t affect so my layout content was messed up.

I also tried to declare my custom layout class as the root element in my_relative_layout.xml, but got inflation exception (i tried both setting root element to null or this, while inflating the xml in MyRelativeLayout.java – with true or false in attach to root).

Answer 1

I ended up using the <merge> tag.
Note that you must set all the RelativeLayout layout params at runtime.
