Is there a way to style a TextView to uppercase all of its letters

Question

I would like to be able to assign a xml attribute or style to a TextView that will make whatever text it has in ALL CAPITAL LETTERS   The attributes android inputType  textCapCharacters  and android capitalize  characters  do nothing and look like they are for user inputed text  not a TextView   I would like to do this so I can separate the style from the content   I know I could do this programmically but again I want keep style out of the content and the code

What about android textAllCaps

It is really very disappointing that you can t do it with styles   lt item name  android textAllCaps  gt true lt  item gt   or on each XML layout file with the textAllCaps  attribute  and the only way to do it is actually using theString toUpperCase   on each of the strings  when you do a textViewXXX setText theString    In my case  I did not wanted to have theString toUpperCase   everywhere in my code but to have a centralized place to do it because I had some Activities and lists items layouts with TextViews that where supposed to be capitalized all the time  a title  and other who did not    so    some people may think is an overkill  but I created my own CapitalizedTextView class extending android widget TextView and overrode the setText method capitalizing the text on the fly   At least  if the design changes or I need to remove the capitalized text in future versions  I just need to change to normal TextView in the layout files   Now  take in consideration that I did this because the App s Designer actually wanted this text  the titles  in CAPS all over the App no matter the original content capitalization  and also I had other normal TextViews where the capitalization came with the the actual content   This is the class   package com realactionsoft android widget   import android content Context   import android util AttributeSet   import android view ViewTreeObserver   import android widget TextView    public class CapitalizedTextView extends TextView implements ViewTreeObserver OnPreDrawListener        public CapitalizedTextView Context context            super context              public CapitalizedTextView Context context  AttributeSet attrs            super context  attrs              public CapitalizedTextView Context context  AttributeSet attrs  int defStyle            super context  attrs  defStyle               Override     public void setText CharSequence text  BufferType type            super setText text toString   toUpperCase    type              And whenever you need to use it  just declare it with all the package in the XML layout    lt com realactionsoft android widget CapitalizedTextView          android id    id text view title          android layout width  wrap content          android layout height  wrap content    gt    Some will argue that the correct way to style text on a TextView is to use a SpannableString  but I think that would be even a greater overkill  not to mention more resource-consuming because you ll be instantiating another class than TextView

I ve come up with a solution which is similar with RacZo s in the fact that I ve also created a subclass of TextView which handles making the text upper-case   The difference is that instead of overriding one of the setText   methods  I ve used a similar approach to what the TextView actually does on API 14   which is in my point of view a cleaner solution    If you look into the source  you ll see the implementation of setAllCaps     public void setAllCaps boolean allCaps        if  allCaps            setTransformationMethod new AllCapsTransformationMethod getContext            else           setTransformationMethod null             The AllCapsTransformationMethod class is not  currently  public  but still  the source is also available  I ve simplified that class a bit  removed the setLengthChangesAllowed   method   so the complete solution is this   public class UpperCaseTextView extends TextView        public UpperCaseTextView Context context            super context           setTransformationMethod upperCaseTransformation              public UpperCaseTextView Context context  AttributeSet attrs            super context  attrs           setTransformationMethod upperCaseTransformation              public UpperCaseTextView Context context  AttributeSet attrs  int defStyle            super context  attrs  defStyle           setTransformationMethod upperCaseTransformation              private final TransformationMethod upperCaseTransformation               new TransformationMethod              private final Locale locale   getResources   getConfiguration   locale            Override         public CharSequence getTransformation CharSequence source  View view                return source    null   source toString   toUpperCase locale    null                      Override         public void onFocusChanged View view  CharSequence sourceText                  boolean focused  int direction  Rect previouslyFocusedRect

By using AppCompat textAllCaps in Android Apps supporting older API s  less than 14   There is one UI widgets that ships with AppCompat named CompatTextView is a Custom TextView extension that adds support for textAllCaps  For newer android API   14 you can use    android textAllCaps  true    A simple example    lt android support v7 internal widget CompatTextView         android id    id text          android layout width  wrap content          android layout height  wrap content          app textAllCaps  true   gt    Source developer android  Update      As it so happens CompatTextView was replaced by AppCompatTextView in   latest appcompat-v7 library    Eugen Pechanec

PixlUI project allows you to use textAllCaps in any textview or subclass of textview including  Button  EditText AutoCompleteEditText Checkbox RadioButton and several others   You will need to create your textviews using the pixlui version rather than the ones from the android source  meaning you have to do this    lt com neopixl pixlui components textview TextView          android layout width  wrap content          android layout height  wrap content          android text   string hello world          pixlui textAllCaps  true    gt    PixlUI also allows you to set a custom typeface font which you put in your assets folder   I m working on a Gradle fork of the PixlUI framework which uses gradle and allows one to specify textAllCaps as well as the typeface from styles rather than requiring them inline as the original project does
