how to edit multiple word in textview in android

Question

I want to bold multiple words from textview's text. I am having words in array that i want to bold in textview's text. how to do it by SpannableStringBuilder??

My array:

string[] array = {"Life","happiness","sadness","tears","smiles","laughter","emotions"};

My Textview text:

Life is filled with happiness, sadness, tears, smiles, laughter and other emotions but when life gets you down, just be strong about it and keep your head up high and have faith in all things in life.

I go through link and other but not found any solution which i want.

    TextView text = (TextView) findViewById(R.id.textView1);
    String[] list = new String[] { "Life","happiness","sadness","tears","smiles","laughter","emotions"};    

    String textData ="Life is filled with happiness, sadness, tears, smiles, laughter and other emotions but when life gets you down, just be strong about it and keep your head up high and have faith in all things in life";
    CharSequence cseq = "";
    for(int i = 0 ; i < list.length ; i++)
    {
          cseq = setSpanBetweenTokens(textData, list[i] , new StyleSpan(Typeface.BOLD_ITALIC));
    }
    text.setText(cseq.toString()); 


public static CharSequence setSpanBetweenTokens(CharSequence text,
            String token, CharacterStyle... cs)
        {
            // Start and end refer to the points where the span will apply
            int tokenLen = token.length();
            int start = text.toString().indexOf(token) + tokenLen;
            int end = text.toString().indexOf(token, start);

            if (start > -1 && end > -1)
            {
                // Copy the spannable string to a mutable spannable string
                SpannableStringBuilder ssb = new SpannableStringBuilder(text);
                for (CharacterStyle c : cs)
                    ssb.setSpan(c, start, end, 0);

                // Delete the tokens before and after the span
                ssb.delete(end, end + tokenLen);
                ssb.delete(start - tokenLen, start);

                text = ssb;
            }

            return text;
        }

.setText(array[0] + " is filled with " + array[1] + " " array[2] ... (and so on) ? — Myth1c, Dec 21 '12 at 07:51

try as using Html.fromHtml:

string[] array = {"Life","happiness","sadness",
"tears","smiles","laughter","emotions"};

String strtemp="";
    for(int i=0;i<array.length-2;i++){
     if(i<array.length-3)
       strtemp+="<b>"+array[i]+",<b/>";
      else{
       strtemp+="<b>"+array[i]+"<b/>";
     }
    }
    txtview=(TextView)findViewById(R.id.selection);
    txtview.setText(Html.fromHtml("YOUR_TEXT HERE"+strtemp+
             "YOUR_TEXT HERE <b>"+array[array.length-1]
                     +"</b> YOUR_TEXT HERE"));

thanks @ρяσѕρєя K but my textview text is not static.. its dynamic.. so i want to check that array values available in string if available then bold it. – Smily Dec 21 '12 at 08:02
@ArchanA : have you try it see my edit answer which is running with static TextView – ρяσѕρєя K Dec 21 '12 at 08:06
@ArchanA : if it not work with dynamic TextView then use SpannableStringBuilder – ρяσѕρєя K Dec 21 '12 at 08:11
@ArchanA : `not get perfect output` means can you share some relevant code then we will try – ρяσѕρєя K Dec 21 '12 at 08:51
@ArchanA: what result you are getting using your current code ? can it's possible to show an image of current output? – ρяσѕρєя K Dec 21 '12 at 09:44

If I understood your question correctly, you have a TextView that has some dynamic text in it, and you want to bold certain words in it. Try something like this:

Spannable sb = new SpannableString(textFromTextView);
for(int i = 0 ; i < array.length ; i++) {
    sb.setSpan(new StyleSpan(android.graphics.Typeface.BOLD),
        textFromTextView.indexOf(array[i]), 
        array[i].length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}

then call the setText() function of your textview with sb as parameter.

Please use the below code:

 textView.setText(Html.fromHtml("<b>"+array[0]+"</b>"+ "is filled with "+"<b>"+array[1]+"</b>"+","+"<b>"+array[2]+"</b>"+","+"<b>"+array[3]+"</b>"+","+"<b>"+array[4]+"</b>"+","+"<b>"+array[5]+"</b>"+"and other"+"<b>"+array[6]+"</b>"+"but when life gets you down, just be strong about it and keep your head up high and have faith in all things in life."));
