Below I have mentioned the code which one through you can create spannableString in Kotlin

val spannableStringBuilder = SpannableStringBuilder()

val boldSpan: StyleSpan = StyleSpan(Typeface.BOLD)

sp_text.setSpan(boldSpan, firstIndex, lastIndex,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

sp_text.setSpan(clickableSpan, firstIndex, lastIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
            sp_text.setSpan(ForegroundColorSpan(ContextCompat.getColor(mContext, R.color.colorPrimary)), firstIndex, lastIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

Answer 2

I would use a string resource such as this:

<string name="health_status"><b>Health:</b> %1$s</string>

When you want to set the health status just use this code:

String ss1 = getString(R.string.health_status, strhealth);

Answer 3

I think you should use 2 different textView, a label and one for the data. it's common and good practice

Answer 4

I am bit late to answer, but I created a method for easy use by using answer already provided here.

    private void setSpanString(String string1, String string2, TextView textView) {
    SpannableStringBuilder builder=new SpannableStringBuilder();
    SpannableString txtSpannable= new SpannableString(string1);
    StyleSpan boldSpan = new StyleSpan(Typeface.BOLD);
    txtSpannable.setSpan(boldSpan, 0, string1.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    builder.append(txtSpannable);
    builder.append(string2);
   textView.setText(builder, TextView.BufferType.SPANNABLE);
}

Answer 5

In kotlin, you can do this. I used this to bold characters/word within a string. For example:

item = "Philippines"

query = "Phil"

result = Philippines

val spannable = SpannableString(item)
val indexStart = item.indexOf(query)
val indexEnd = indexStart + query.length
spannable.setSpan(StyleSpan(Typeface.BOLD), indexStart, indexEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

and use it like this

textView.text = spannable

Answer 6

The easiest way is

textview1.setText(Html.fromHtml("<b>Health:</b> good"));

The mistake in your code is to use string concatenation here: "\n"+ss1+strhealth+"\n\n" which strips out all formatting because the components are taken as normal strings.
