In kotlin  in  kt file make changes   edit text filters   edit text filters   InputFilter AllCaps     Use synthetic property for direct access of widget with id  And in XML  for your edit text add a couple of more flag as    lt EditText     android id    id edit text qr code      android layout width  match parent      android layout height  wrap content         other attributes        android textAllCaps  true      android inputType  textCapCharacters        gt    This will update the keyboard as upper case enabled

If you want to force user to write in uppercase letters by default in your EditText  you just need to add android inputType  textCapCharacters    User can still manually change to lowercase

It is not possible to force a capslock only via the XML  Also 3rd party libraries do not help  You could do a toUpper   on the text on the receiving side  but there s no way to prevent it on the keyboard side You can use XML to set the keyboard to caps lock  Java You can set the input type to  TYPE CLASS TEXT  TYPE TEXT FLAG CAP CHARACTERS   The keyboard should honor that  Kotlin android inputType  quot textCapCharacters quot

Even better    one liner in Kotlin        gets your previous attributes in XML  plus adds AllCaps filter      lt your edit text gt  setFilters  lt your edit text gt  getFilters     InputFilter AllCaps      Done

Rather than worry about dealing with the keyboard  why not just accept any input  lowercase or uppercase and convert the string to uppercase   The following code should help   EditText edit    EditText findViewById R id myEditText   String input       input   edit getText    input   input toUpperCase      converts the string to uppercase   This is user-friendly since it is unnecessary for the user to know that you need the string in uppercase  Hope this helps

You can add the android textAllCaps  true  property to your xml file in the EditText  This will enforce the softinput keyboard to appear in all caps mode  The value you enter will appear in Uppercase  However  this won t ensure that the user can only enter in UpperCase letters  If they want  they can still fall back to the lower case letters  If you want to ensure that the output of the Edittext is in All caps  then you have to manually convert the input String using toUpperCase   method of String class

I m using Visual Studio 2015 Xamarin to build my app for both Android 5 1 and Android 6 0  same apk installed on both     When I specified android inputType  textCapCharacters  in my axml  the AllCaps keyboard appeared as expected on Android 6 0  but not Android 5 1   I added android textAllCaps  true  to my axml and still no AllCaps keyboard on Android 5 1   I set a filter using EditText SetFilters new IInputFilter     new InputFilterAllCaps       and while the soft keyboard shows lower case characters on Android 5 1  the input field is now AllCaps   EDIT  The behavioral differences that I observed and assumed to be OS-related were actually because I had different versions of Google Keyboard on the test devices   Once I updated the devices to the latest Google Keyboard  released July 2016 as of this writing   the  All Caps  behavior was consistent across OSes   Now  all devices show lower-case characters on the keyboard  but the input is All Caps because of SetFilters new IInputFilter     new InputFilterAllCaps
