private void setSpann(){//1ForegroundColorSpan 文本顏色(前景色)SpannableString spannableString = new SpannableString("我是一個無聊的文本,啦啦啦啦啦啦");ForegroundColorSpan colorSpan = new ForegroundColorSpan(Color.parseColor("#0099EE"));spannableString.setSpan(colorSpan, 9, spannableString.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);textView3.append("\n1");textView3.setText(spannableString);//2BackgroundColorSpan 背景色spannableString.setSpan(new BackgroundColorSpan(Color.parseColor("#0099EE")), 6, spannableString.length(), spannableString.SPAN_INCLUSIVE_EXCLUSIVE);textView3.append("\n2");textView3.append(spannableString);// 3.

代碼:
String sms = "審計系統(tǒng)在線"; String sjs = "審計系統(tǒng)在線"; int fstart = 4; int fend = 6; if (sms.contains("在線")) {SpannableStringBuilder style = new SpannableStringBuilder(sms);style.setSpan(new ForegroundColorSpan(Color.rgb(166, 116, 50)), fstart, fend, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);nethomesmstatus.setText(style); } else {nethomesmstatus.setText(sms); }?
