inflate a view without XML in Android

first of all, please any one can tell me is it possible to inflate a view without XML ?

Description is like this:
I have dynamically generated a view hierarchy by coding, like 

Relative layout contain 4 Linear layouts
-1st Linear Layout contain Image View
-2nd Linear Layout contain surface view
-3rd Linear Layout contain Button
-4th Linear Layout contain Text Box

and there is no issue in generating all view / view hierarchy (I tested by debugging and inspecting child views)

But I am not able to set it as a setContent()
Because I don't have XML and not allowed to use XML(not sure why), i.e. I have no access of R.Layout. So I cant use inflater.Inflate(R.Layout...)

When I am setting main relative layout as a content, I am getting following error

12-16 11:32:03.653: E/AndroidRuntime(22564): java.lang.RuntimeException: Unable to start activity ComponentInfo{my.package.class}: android.content.res.Resources$NotFoundException: Resource ID #0x1d97b

Anyone have any idea ?

Solution

  • is it possible to inflate a view without XML ?

    No. The definition of the term "inflation" in Android is to convert an XML resource file into a corresponding tree of Java objects. Layout inflation converts an XML layout resource into a corresponding tree of View objects.

    But I am not able to set it as a setContent()

    I do not know what setContent() method it is that you are referring to. To put a View as the main content of an Activity, use setContentView().
