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

android, spannablestring

Solution

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);

Problem

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?
