Answer 1

in your strings file

<string name="your_text">
<![CDATA[
<p> <b>Title</b> </p>
<p><b><i>Step 1</i></b><p>step1 content content content  content content content</p></p>
<p><b><i>Step 2</i></b><p>step2 content  content content content  content content content</p></p>
]]>
</string>

Then in your activity

    TextView tv=(TextView)findViewById(R.id.textView1);
    tv.setText(Html.fromHtml(getString(R.string.your_text)));

-----------------OR-----------------------

Just build your String in HTML and set it:

    String sourceString = "<b>" + id + "</b> " + name; 
    mytextview.setText(Html.fromHtml(sourceString));

Answer 2

Try the following way-

sb.setText(Html.fromHtml("<b>" +" Contact Name:" + name + "</b>"));

Reply back if this doesn't resolve the issue.

UPDATE:

If you only want to append the specified text to the TextView's display buffer then still your code is incorrect may be a typo.

You used this-

sb.append(Html.fromHtml("\n"+" Contact Name:" + name); 

Instead use this -

sb.append(Html.fromHtml("<b>"+" Contact Name:" + name + "</b>")); 

Note the <b> tag start and </b> tag end.

Also note that you haven't closed your end bracket with )

UPDATE:

I guess that sb is your StringBuffer and not the TextView. So you have to set this on a TextView and not in a StringBuffer.

Let your TextView is,

TextView tv = (TextView)findViewById(R.id.ur_text_view_id);

Then you simply do the following ---

tv.setText(Html.fromHtml("<b> Contact Name:</b>" + name));

UPDATE:

Since you are using StringBuffer to store all the contact details so just use the following-

 //the below in a loop to add each name to string buffer
 for(<loop through name length>)
    sb.append("<br>" + "<b>Contact Name</b>:" + name);

 //finally use this outside loop to set text to the textview.
 tv.setText(Html.fromHtml(sb.toString()));

NOTE: The last UPDATE is only useful if the first line is in a loop appending each name in a string buffer. Otherwise you can directly use the second last UPDATE of this answer.

try using spanable text

    StringBuilder sb = new StringBuilder();
    String s1 = "Contact Name:" ;
    sb.append(s1);
    String nameString = " name"; 
    sb.append(nameString);
    String s2 = "\nEmail :";
    sb.append(s2);
    String emailString = " email";
    sb.append(emailString);
    String s3 = "\nPhoneNo :";
    sb.append(s3);
    String phNoString = " 121564";
    sb.append(phNoString);
    SpannableString ss1=  new SpannableString(sb);
    ss1.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 0,s1.length(), 0);
    ss1.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), s1.length() + nameString.length(),s1.length() + nameString.length()+s2.length(), 0);
    ss1.setSpan(new StyleSpan(android.graphics.Typeface.BOLD),s1.length() + nameString.length()+s2.length()+emailString.length(), s1.length()+nameString.length()+s2.length()+emailString.length()+s3.length(), 0);

    TextView tv= (TextView) findViewById(R.id.textview);
    tv.setText(ss1);

Answer 4

1.

        SpannableStringBuilder sb = new SpannableStringBuilder("HELLOO");
        final StyleSpan bss = new StyleSpan(android.graphics.Typeface.BOLD); // Span to make text bold
        sb.setSpan(bss, 0, 4, Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold 
        etx.setText(sb);

2.

        etx.setText(Html.fromHtml("HELLOO <b>ADVENTURE!</b>")); 

try above code.

Answer 5

you need to format your string in html form during creation then apply formHtml method on whole string. Html.formHtml() method Returns displayable styled text(Spanned) from the provided HTML string. if you are applying this method on substring(with html tags) after that appending them to StringBuffer, sb.append(Html.fromHtml("\n"+" < b>Contact Name< /b>:" + name) actually calls Spanned.toString() method resulting in removal of html tags hence you are viewing plain text in text view.

try this way this will solve your problem

     StringBuffer sb=new StringBuffer();
     sb.append("hello");
     sb.append("<b>How</b>");
     sb.append("are you");
     tv.setText(Html.fromHtml(sb.toString()));
