Android: Use two Custom Fonts for one EditText

Question

This may sound a bit fishy but, even i dont know if this is possible in android or not. The requirement is i need to write two languages in the edittext, one urdu and the other is default english, now the problem is in the typeface, since i have to use the urdu typeface as a default, i used setTypeface like the following:

editText.setTypeface(englishFont);

But the problem is the english in this typeface is not good, in fact it is smaller than usual for this i have to use another typeface for English, but this creates the problem, i get the getText from the editText, detect the urdu and english characters and then use spannableStringBuilder to change the typeface accordingly as following:

if(Arrays.asList(urduCodes).contains(Integer.toHexString(text.charAt(i)).toUpperCase()))
                {
                    System.out.println("different: "+text.charAt(i));
                    SpannableStringBuilder urduBLD;
                    urduBLD = new SpannableStringBuilder("");
                    urduBLD.append(edi.getText().charAt(i));
                    System.out.println("urduBLD: "+urduBLD);
                    urduBLD.setSpan(new StyleSpan(urduFont.getStyle()),urduBLD.length(),urduBLD.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
                    stringBuilder.append(urduBLD);



                } else 
                {
                    System.out.println(text.charAt(i)+"-Code:"+(int)text.charAt(i)+"-"+Integer.toHexString(text.charAt(i)));
                    SpannableStringBuilder engBLD;
                    engBLD = new SpannableStringBuilder("");
                    engBLD.append(edi.getText().charAt(i));
                    System.out.println("engBLD: "+engBLD);
                    engBLD.setSpan(new StyleSpan(englishFont.getStyle()),engBLD.length(),engBLD.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
                    stringBuilder.append(engBLD);


                }

But this does not solve the problem, the text in editText remains the same, no change in typeface. Is this possible or not??

Than why not you are using two eidtText one for urdhu and other for English @blogger — Jhaman Das, Apr 11 '16 at 07:43

Because in the activity only one EditText is required and both the languages should be in the same EditText — Hunain Usman, Apr 11 '16 at 07:46
@Opiatefuchs this is Correct/Right for TextView not EditText, i have tested that already... — Hunain Usman, Apr 11 '16 at 07:48

After doing some research and hardwork finally i was able to create a universal function for this:

public SpannableStringBuilder setWord(String text)
    {
        tokenList = new ArrayList<String>();

        startIndext = 0;
        endIndex = 0;
        isEnglish = false;

        stringBuilder = new SpannableStringBuilder("");

        Log.i("CustomUrduKeyBoard","inside setWord text is: "+text+" stringBuilder: "+stringBuilder);
        if(text == null)
        {

        } else 
        {

            for (int i = 0; i < text.length(); i++) 
            {
//              System.out.println(text.charAt(i) + "-Code:" + (int) text.charAt(i)
//                      + "-" + Integer.toHexString(text.charAt(i)));
                if (text.charAt(i) < 255) 
                {
                    if (!isEnglish) 
                    {
                        endIndex = i;
                        String token = text.substring(startIndext, endIndex);

                        SpannableStringBuilder urduBLD;
                        urduBLD = new SpannableStringBuilder("");
                        urduBLD.append(token);

                        urduBLD.setSpan(new CustomTypefaceSpan("", urduFont),0,urduBLD.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
                        stringBuilder.append(urduBLD);
                        tokenList.add(urduBLD.toString());
                        startIndext = endIndex;
                    }
                    isEnglish = true;
                    // english
                    continue;
                } else 
                {
                    if (isEnglish) 
                    {
                        endIndex = i;
                        String token = text.substring(startIndext, endIndex);

                        SpannableStringBuilder engBLD;
                        engBLD = new SpannableStringBuilder("");
                        engBLD.append(token);

                        engBLD.setSpan(new CustomTypefaceSpan("", englishFont),0,engBLD.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
                        stringBuilder.append(engBLD);
                        tokenList.add(engBLD.toString());
                        startIndext = endIndex;
                    }
                    isEnglish = false;
                    // urdu
                    continue;
                }
            }

            String token = text.substring(startIndext, text.length());

            for (int i = 0; i < token.length(); i++) 
            {
                if (token.charAt(i) < 255) 
                {

                    SpannableStringBuilder urduBLD;
                    urduBLD = new SpannableStringBuilder("");
                    urduBLD.append(token);

                    stringBuilder.append(urduBLD);
                    tokenList.add(urduBLD.toString());

                    break;
                } else
                {

                    SpannableStringBuilder engBLD;
                    engBLD = new SpannableStringBuilder("");
                    engBLD.append(token);

                    engBLD.setSpan(new CustomTypefaceSpan("", urduFont),0,engBLD.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
                    stringBuilder.append(engBLD);
                    tokenList.add(engBLD.toString());

                    break;
                }
            }

        }

        return stringBuilder;
    }
