部分字體著色

代碼：

String sms = "審計系統在線"; String sjs = "審計系統在線"; 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); }

字體樣式

字體類型
Typeface.DEFAULT：默認字體，常規字體類型
Typeface.DEFAULT_BOLD：黑體字體類型
Typeface.MONOSPACE：等寬字體類型
Typeface.SANS_SERIF：sans serif字體類型
字體樣式
Typeface.BOLD //粗體
Typeface.BOLD_ITALIC //粗斜體
Typeface.ITALIC //斜體
Typeface.NORMAL //常規

?//下劃線?

textView.getPaint().setFlags(Paint. UNDERLINE_TEXT_FLAG );

//抗鋸齒

textView.getPaint().setAntiAlias(true);

//中劃線
