You must create them under strings xml   lt string name  close  gt Close lt  string gt        You must replace and reference like this  android text   string close   gt    Do not use  strings even though the XML file says strings xml or else it will not work

It is not good practice to hard code strings into your layout files   You should add them to a string resource file and then reference them from your layout    This allows you to update every occurrence of the word  Yellow  in all layouts at the same time by just editing your strings xml file    It is also extremely useful for supporting multiple languages as a separate strings xml file can be used for each supported language   example  XML file saved at res values strings xml    lt  xml version  1 0  encoding  utf-8   gt   lt resources gt       lt string name  yellow  gt Yellow lt  string gt   lt  resources gt    This layout XML applies a string to a View    lt TextView android layout width  fill parent            android layout height  wrap content            android text   string yellow    gt    Similarly colors should be stored in colors xml and then referenced by using  color color name   lt  xml version  1 0  encoding  utf-8   gt   lt resources gt       lt color name  Black  gt  000000 lt  color gt   lt  resources gt

It is not good practice to hard code strings into your layout files  code  You should add them to a string resource file and then reference them from your layout     This allows you to update every occurrence of the same word in all layouts at the same time by just editing your strings xml file  It is also extremely useful for supporting multiple languages as a separate strings xml file can be used for each supported language the actual point of having the  string system please read over the localization documentation  It allows you to easily locate text in your app and later have it translated  Strings can be internationalized easily  allowing your application to support multiple languages with a single application package file  APK     Benefits   Lets say you used same string in 10 different locations in the code  What if you decide to alter it  Instead of searching for where all it has been used in the project you just change it once and changes are reflected everywhere in the project  Strings don   t clutter up your application code  leaving it clear and    easy to maintain

A good practice is write text inside String xml  example   String xml   lt  xml version  1 0  encoding  utf-8   gt   lt resources gt       lt string name  yellow  gt Yellow lt  string gt   lt  resources gt    and inside layout    lt TextView android layout width  fill parent        android layout height  wrap content        android text   string yellow    gt

You can go to Design mode and select  Fix  at the bottom of the warning  Then a pop up will appear  seems like it s going to register the new string  and voila  the error is fixed
