No,It's not possible.

To set XML file as layout in your activity you have that file in res/layout directory and also make sure it's id entry in R.java files.

Without keeping it in res/layout you can't apply it as a layout to your activity.

Basically when you put any xml layout file in res/layout then it's id entry created in

  public static final class layout

in R.java files, And from there when you set that file as a setcontentView() of your activity or inflate it, the android nutshell make a view from that raw layout xml file and apply it to your activity.

Loading XML Layout File from SD CARD is simply impossible because

  1. XML Layout file resources need to generate id with R.java-Java Generated File which can be generated at compile time only. You can generate if you simple copy that XML Layoutfrom your SD-CARD to res/layout/ folder at time of writing your application

  2. R.java-Java Generated file is needed to wired up the Java code and XML Layout file. If you have used that XML Layout file resources e.g[Button,EditText etc..,] in your application.

  • can i get xml layout file from other apk file that was already on sd card?......just trying other option – rajG Jan 04 '13 at 10:15
  • @rajG you can definitely get the xml files from another apk package. `But they are just useless in your application`. As that `XML Layout File never been complied with your application.` – Vikalp Patel Jan 04 '13 at 10:47

Not possible, because xml layouts are compiled in a specific format. You would need to compile the xml and inject it in the apk, which is not feasible on the device itself.
