Xtend Closures are automatically converted to anonymous classes of the expected type.

That is :

onClickListener = [
this.textMessage('Hello you clicked me!').show
]

really translates to the following Java code:

setOnClickListener(new OnClickListener() {
public void onClick(View it) {
AppActivity.this.textMessage("Hello you clicked me!").show();
}
});

Hi,I'm very interested in developing android app in Xtend.

How does closure convert to interface?
ex:
[this.textMessage('Hello you clicked me!').show]
->
new OnClickListener() {
public void onClick(View v) {
// ...
}
}
Where does method name(ex:'onClick') come from...?

Hi Toby,
in Xtend you derefernce inner classes with a dollar sign as namespace delimiter. See the project on Github.

I noticed that the R class (generated by Android) is not available inside the Activity. In your example project, if you try to access R::layout::main for example, Xtend gives errors, even though you can add it to the generated Java class without issues. Is there a way around this problem?

Hi Sven,

there is a project on github called AndroText (currently under development), which aims to generate android application based on Xtext technology, you could check it out (https://github.com/CMark/androtext), it can generate gui elements, data binding...

Thanks Sven that is exactly what I needed!! I was trying to find a duplicate file (looking to try to remove them) but instead I just needed to add the jar as dependencies in the build path.

I copied the needed jars to the project. Android complaints about duplicate resources. Unfortunately the sometimes exist :-(

I pushed the correctly configured android project to github :

How where you able to work around the error:
Error generating final archive: Found duplicate file for APK: .settings/org.eclipse.jdt.core.prefs
eclipse/plugins/com.google.guava_10.0.1.1.jar
eclipse/plugins/com.google.inject_3.0.0.no_no_aop.jar

I can get it to compile and generate the right Java code but not deploy. I can download the basic eclipse and try it since I am using the J2EE eclipse version.
