MonstersRecyclerViewWithSQLite3-start

In this Project we will add Internationalisation, Splash screen and set material themes for the app.

TODO: Add a listener of each button inside the recyclerView

•  1) modify the ViewHolder, add a button listener inside of the bind method
  

•  2) use a Snackbar to display the name of the monster when this button is clicked / tapped
  

TODO: Add a splash screen

•  1) create a theme for your splash screen in styles.xml
  

•  2) add it to your AndroidManifest.xml
  

•  3) in MainActitivy.java restore the old theme, otherwise you will see the splash screen as a background image
  

TODO: set a new Material theme for your app

•  1) go to any of these websites to select a pre defined set of colors, or create your own one
  

  •      https://www.materialpalette.com/
    

  •      https://material.io/resources/color/#!/?view.left=0&view.right=0
    

  •      https://codecrafted.net/randommaterial
    

  •      additional info: https://material.io/develop/android
    

•  2) Export the colors as xml files
  

•  3) replace those colors in your colors.xml file ( be aware that android uses as color names:
  

  •      colorPrimary, colorPrimaryDark and colorAccent
    

TODO: Internationalisation

•  1) Remove all hardcoded text in the app, create a key for every text in strings.xml
  

  •  there will be some cases where you want to pass parameters to the text defined in strings.xml ie:
    

    •          <string name="my_welcome_messages">Welcome, %1$s! You have %2$d new notifications.</string>
      

    •          where
      

      •              %1 and %2 are the possitions of the parameters
        

      •              $s, $d are the datatypes expected for each parameter
        

    •           In code you should call it in this way:
      

      •              rootView.getContext().getString(R.string.view_holder_monster_votes_label_value, monster.getVotes()) *      2) right click on the file -> Open Translation Editor
        

  •      click the globe icon
    

  •      select thelanguage you want to translate the file to
    

  •      fill up the translations
    

•  3) Finally change the language of your device to test the internationalisation:
  

  •      settings -> Language & Input -> Language
    

  •      and set the new language for your device.
    

  •      Run your app and check the new language of your app
