B4A Library Multi Language helper

A small library for multilingual applications for newcomers.
It uses a text file with name: translation.txt which must always be installed in File.DirAssets folder.
translation.txt
B4X:
key;english;french;greek;
button1;File;Déposer;Αρχείο;
button2;Edit;Éditer;Επεξεργασία;
button3;Exit;Sortir;Έξοδος;
msg_hello_world;Hello World;Bonjour le monde;Γεια σου κόσμε;

  • The first line includes the key word as first column and the names of the languages to be used. You can use as many languages as you want by entering their name separated by the character ";" . Don't forget to close with ";" last language as in example file.
  • The first column of the translation file refers to the keyword that you will use to call the corresponding translation.
  • Each word is separated by the previous one with the character ";"

How to use: Install library and define a variable as Translation Class

B4X:
Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private lang As Translation
    Private Button1 As Button
    Private Button2 As Button
    Private Button3 As Button
End Sub

Public Sub Initialize
    lang.Initialize
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    Button1.Text = lang.getWord("button1","greek")
    Button2.Text = lang.getWord("button2","english")
    Button3.Text = lang.getWord("button3","french")
End Sub

Private Sub Button1_Click
    xui.MsgboxAsync(lang.getWord("msg_hello_world", "greek"), "B4X")
End Sub

Private Sub Button2_Click
    xui.MsgboxAsync(lang.getWord("msg_hello_world", "english"), "B4X")
End Sub

Private Sub Button3_Click
    xui.MsgboxAsync(lang.getWord("msg_hello_world", "french"), "B4X")
End Sub

Language
Version: 0.1 beta

Class: Translation

Methods
:
  • Initialize Initialize and do all the job loading a map with key and values of each line
  • languages Returns a list of languages written in translation.txt file
  • getWord("key as string", "language name as shown in translation.txt file"). Returns a string with the word in chosen language

The library is not checking for errors in translation.txt file so it is your responsibilty to write it as the example above.

This is my first library so be kind!
