Use SpannableString in Android Home Screen widgets?

Question

Can I use SpannableStrings in a widget's textView? I tried and all it rendered was plain text. I don't know if it is something I'm doing wrong (most likely), or if it just isn't possible for some reason.

Here's the code I'm using (nothing special really...)

 public static void updateWidgetState(Context paramContext, String paramString, Integer appWidgetId) {

    SpannableString majorLabel = new SpannableString("");
    SpannableString minorLabel = new SpannableString("");
    if (position > -1) {
        majorLabel = GetParsedMajorLabel(paramContext);
        minorLabel = GetParsedMinorLabel(paramContext);
    }
    RemoteViews localRemoteViews = buildUpdate(paramContext, paramString, appWidgetId);
    localRemoteViews.setTextViewText(R.id.majorlabel, majorLabel);
    localRemoteViews.setTextViewText(R.id.minorlabel, minorLabel);
 }

Answer 1

If you would like to display formatted text in a TextView, use fromHtml

Answer 2

String urlink = "http://www.google.com";
String link = "<a href=\"+urlink+ >link</a>"; 
textView.setText(Html.fromHtml(link));

Answer 3

you can easily set Spannable String in widget. what I did is I used SpannableStringBuilder as set it to remoteView's textView.

  views.setTextViewText(R.id.rsTV, WidgetUtils.setPriceSpannableHomeScreenString(currentUserBalance.balance, context))


fun setPriceSpannableHomeScreenString(price: String, context: Context?): SpannableStringBuilder {

    val builder = SpannableStringBuilder()

    if (AppClass.hasValue(price) && context != null) {

        val st = StringTokenizer(price.trim { it <= ' ' }, ".") //pass dot as delimeter

        val balanceArrayList = ArrayList<String>()

        //iterate through tokens

        while (st.hasMoreTokens()) {
            balanceArrayList.add(st.nextToken("."))
        }

        val priceRsText = context.getString(R.string.rs)
        var priceBeforeDecimal = ""
        var priceAfterDecimal = ""

        if (balanceArrayList.size > 0) {

            if (balanceArrayList.size > 0 && balanceArrayList.get(0) != null) {
                priceBeforeDecimal = balanceArrayList.get(0)
            }

            if (balanceArrayList.size >= 2 && balanceArrayList.get(1) != null) {
                priceAfterDecimal = balanceArrayList.get(1)
            }

        }

        val firstValue = "$priceRsText.$priceBeforeDecimal."

        val lastValue = priceAfterDecimal


        val txtSpannable = SpannableString(firstValue)
        val boldSpan = StyleSpan(Typeface.BOLD)
        txtSpannable.setSpan(RelativeSizeSpan(1.5f), 0, firstValue.length, 0) // set size
        txtSpannable.setSpan(boldSpan, 0, firstValue.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
        builder.append(txtSpannable)
        builder.append(lastValue)
        // priceSpannableTextView.setText(builder, TextView.BufferType.SPANNABLE)

        return builder
    }

    return builder
}
