Phonegap plugin activity import plugin

Question

I am developing a Cordova plugin with activity, and I need to access the R.layout application from this operation so that I can call setContentView.

I am currently doing this by creating import com.example.hello.Rand then on onCreate method I callsetContentView (R.layout.mysurfaceview) `:

The problem is that my plugin will only work if the application name com.example.hello, but I need to install my plugin in different applications without manual import.

Is there a way to do general imports, something like, import <appName>.Ror any other ways to do this?

Answer 1

, Resource.getIdentifier(). , . :

 String package_name = getApplication().getPackageName();
 Resources resources = getApplication().getResources();
 setContentView(resources.getIdentifier("my_activity_layout", "layout", package_name));

"my_activity_layout" - xml-. , . , , plugin.xml res/layout.

<source-file src="path/to/your/layout/file.xml" target-dir="res/layout"/>

Phonegap, .

    return deferral.promise;
}

Just add as hook_upug_install (for the Android platform) to your plugin.xml file:

<hook type="after_plugin_install" src="scripts/android/addResourcesClassImport.js" />

Hope this helps someone!
