Android TextView Justify Text

Question

How do you get the text of a TextView to be Justified  with text flush on the left- and right- hand sides     I found a possible solution here  but it does not work  even if you change vertical-center to center vertical  etc

You can use justificationMode as inter word in xml  You have to remember that this attribute is available for api level 26 and higher  For that you can assign targetApi as o  The full code is given bellow  lt com google android material textview MaterialTextView                             android justificationMode  quot inter word quot              tools targetApi  quot o quot    gt

FILL HORIZONTAL is equivalent to  CENTER HORIZONTAL  You can see this code snippet in textview s source code   case Gravity CENTER HORIZONTAL  case Gravity FILL HORIZONTAL      return  mLayout getLineWidth 0  -   mRight - mLeft  -             getCompoundPaddingLeft   - getCompoundPaddingRight                   getHorizontalFadingEdgeLength

To justify text in android I used WebView       setContentView R layout main        WebView view   new WebView this       view setVerticalScrollBarEnabled false          LinearLayout findViewById R id inset web view   addView view        view loadData getString R string hello    text html  charset utf-8    utf-8      and html    lt string name  hello  gt   lt   CDATA   lt html gt    lt head gt  lt  head gt    lt body style  text-align justify color gray background-color black   gt    Lorem ipsum dolor sit amet  consectetur    adipiscing elit  Nunc pellentesque  urna   nec hendrerit pellentesque  risus massa   lt  body gt   lt  html gt     gt   lt  string gt    I can t yet upload images to prove it but  it works for me

For html formating you don t need to call the Webkit  you could use Html fromHtml text  to do the job   Source   http   developer android com guide topics resources string-resource html

On android  to left justify text and not have truncation of the background color  try this  it worked for me  producing consistent results on android  ff  ie  amp  chrome but you have to measure out the space that s left in between for the text when calculating the padding    lt td style  font-family Calibri Arial      font-size 15px      font-weight 800      background-color  f5d5fd      color black      border-style solid      border-width 1px      border-color  bd07eb      padding-left 10px      padding-right 1000px      padding-top 3px      padding-bottom 3px   gt    The hack is the padding-right 1000px  that pushes the text to the extreme left   Any attempt to to a left or justify code in css or html results in a background that s only half width

The  CommonsWare answer is correct  Android 8 0  does support  Full Justification   or simply  Justification   as it is sometimes ambiguously referred to    Android also supports  Flush Left Right Text Alignment   See the wikipedia article on Justification for the distinction  Many people consider the concept of  justification  to encompass full-justification as well as left right text alignment  which is what they end up searching for when they want to do left right text alignment  This answer explains how to achieve the left right text alignment   It is possible to achieve Flush Left Right Text Alignment  as opposed to Full Justification  as the question is asking about   To demonstrate I will be using a basic 2-column form  labels in the left column and text fields in the right column  as an example  In this example the text in the labels in the left column will be right-aligned so they appear flush up against their text fields in the right column    In the XML layout you can get the TextView elements themselves  the left column  to align to the right by adding the following attribute inside all of the TextViews    lt TextView           android layout gravity  center vertical end  gt          lt  TextView gt    However  if the text wraps to multiple lines  the text would still be flush left aligned inside the TextView  Adding the following attribute makes the actual text flush right aligned  ragged left  inside the TextView    lt TextView           android gravity  end  gt          lt  TextView gt    So the gravity attribute specifies how to align the text inside the TextView layout gravity specifies how to align layout the TextView element itself

I think there are two options    Use something like Pango that specializes in this via the NDK and render text to an OpenGL or other surface  Use Paint measureText   and friends to get the lengths of words and lay them out manually on a Canvas in a custom view
