Android Widget Variable Generator

Declaring variables for Android widgets is very repetitive. This Ruby script generates the code that can be copy-pasted into onCreate. Use Android Studio (Cmd+Option+F) to refactor the variables into member variables.

    #androidLayoutToVars.rb
    require 'nokogiri'
    class LayoutProcessor < Nokogiri::XML::SAX::Document
    def start_document
    end

    def start_element(name, attrs=[])
        attrs = attrs.to_h
        if attrs.key?('android:id')
        varName = attrs['android:id'][5..]
        declaration = "#{name} #{varName} = findViewById(R.id.#{varName});"
        puts declaration
        end
    end

    def end_element(name)
    end

    def end_document
    end
    end

    parser = Nokogiri::XML::SAX::Parser.new(LayoutProcessor.new)
    parser.parse(File.open(ARGV[0]))
