Why doesn't my text show up with style when using SpannableStringBuilder?

Question

I have a problem with a SpannableString object.

Below's a short example:

SpannableString spanstr = new SpannableString("Bold please!");
spanstr.setSpan(new StyleSpan(Typeface.BOLD), 0, spanstr.length(), 0);

SpannableStringBuilder sb = new SpannableStringBuilder();
sb.append(spanstr);
sb.append("\n"); // A newline
sb.append("The first line is bold. This one isn't.");

CharSequence cq = sb.subSequence(0, sb.length());
// ^There's no such method to return a SpannableString,
// so I try to return a CharSequence instead.

// And then, at last:
TextView contentView = (TextView) findViewById(R.id.some_id);
contentView.setText(cq);

What the example's trying to do is showing this:

Bold please!
The first line is bold. This one isn't.

But the problem is: the first line of the text won't show up in bold.

Why doesn't it do it expected?

Use the spannable string builder for setting as text in textview :

contentView.setText(sb);

or else you can do like this :

SpannableStringBuilder spanstr = new SpannableStringBuilder("Bold please!");
spanstr.setSpan(new StyleSpan(Typeface.BOLD), 0, spanstr.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
spanstr.append("\n");
spanstr.append("The first line is bold. This one isn't.");
contentView.setText(spanstr);

use SpannableStringBuilder instance itself.

contentView.setText(sb);

output with your code:

Thank you very much. I called `toString()` on `spannableBuilder` and couldn't understand why I was not seeing a styled text. – Renat Kaitmazov Sep 14 '16 at 09:25

@RenatKaitmazov You should not call toString() method on SpannableBuilder, if you do so it will consider it as String, not a styled text – Pragnani Sep 14 '16 at 14:18

Try the below. You need to set the spannable string to the textview. So set the spannable string to your text as below

String s= "The first line is bold. This one isn't";
String title="Bold Please!";  
TextView tv = (TextView) findViewById(R.id.some_id);
tv.setText("");
SpannableString ss1=  new SpannableString(title);
ss1.setSpan(new StyleSpan(Typeface.BOLD), 0, ss1.length(), 0);
tv.append(ss1);
tv.append("\n");
tv.append(s);

I tried the above and you can see the resulting snapshot below.

If you use custom font in your device. There is such a silly bug i think. Please change your custom font to default in your device and try again.

late for the answer but for future reader who facing this problem,

make sure you don't call toString() when setting builder into textview

val builder = SpannableStringBuilder()
builder.setspan(xxxxxxx)

do this :

textview.text = builder

and dont do this :

textview.text = builder.toString() //will remove the styling

alas, the styling from SpanableStringBuilder wont work

Why doesn't my text show up with style when using SpannableStringBuilder?
