How to get this special space character ␣ into an Android Button? -


i want symbolize space in android button so:

  1. in strings.xml file define <string name="spacesymbol">␣</string>
  2. in layout xml file set android:text "@string/spacesymbol"

when run application button shows nothing. ideas? if other character symbolizes space works other ␣ i'll glad use it

you can wrap space char in ![cdata[ ... ]] in string resource..that may bring in. should check character in roboto font also

given character not represented in roboto font, can use spannablestring replace special character own image:

you should create drawable (or bitmap) space image in want use. in example assigned variable 'drawable':

  spannablestring textspan = new spannablestring(sb);   pattern pattern = pattern.compile("#_", pattern.case_insensitive);   matcher = pattern.matcher(textspan);   while(matcher.find()) {        textspan.setspan(new imagespan(this, drawable, imagespan.align_baseline), matcher.start(), matcher.end(), spanned.span_inclusive_inclusive);   }

in string (in code example) have replaced space symbol 2 characters "#_". pattern find each occurence of "#_" , replace drawable.

then can use spannablestring charsequence argument anywhere it's defined (toast.maketext, textview.settext, etc) :

textview tv = (textview) findviewbyid(..); tv.settext(textspan);
