部分字体着色
代码:
String sms = "审计系统在线";
String sjs = "审计系统在线";
int fstart = 4;
int fend = 6;
if (sms.contains("在线")) {
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);
}
效果:
textView.setShadowLayer(2,6,20,R.color.colorPrimary);//清晰度,偏移量,最后一个无效参数
