Troubleshooting when using SpannableStringBuilderfinal TextView textTroubles = (TextView) findViewById(R.id.text_view_font_3);
SpannableStringBuilder word3 = Caution: must first append or set text to SpannableStringBuilder or SpannableString
then set the spans to them,otherwise,IndexOutOfBoundException is thrown when setting spansword3.append(one);
For AbsoluteSizeSpan,the flag must be set to 0,it will apply this span to until end of textword3.setSpan(Spannable.SPAN_INCLUSIVE_INCLUSIVE);
For BackgroundColorSpanSpan,it will apply this span to end of textnew BackgroundColorSpan(Color.DKGRAY),0); Spannable.SPAN_INCLUSIVE_INCLUSIVE);word3.append(two);
