      String str="这是设置TextView部分文字背景颜色和前景颜色的demo!";

        int bstart=str.indexOf("背景");

        int bend=bstart+"背景".length();

        int fstart=str.indexOf("前景");

        int fend=fstart+"前景".length();

        SpannableStringBuilder style=new SpannableStringBuilder(str);

        style.setSpan(new BackgroundColorSpan(Color.RED),bstart,bend,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  

        style.setSpan(new ForegroundColorSpan(Color.RED),fstart,fend,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);

        TextView tvColor=(TextView) findViewById(R.id.tv_color);

        tvColor.setText(style);

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：

 

 

字体阴影

textView.setShadowLayer(2,6,20,R.color.colorPrimary);//清晰度，偏移量，最后一个无效参数

 

字体样式

字体类型
Typeface.DEFAULT：默认字体，常规字体类型
Typeface.DEFAULT_BOLD：黑体字体类型
Typeface.MONOSPACE：等宽字体类型
Typeface.SANS_SERIF：sans serif字体类型
字体样式
Typeface.BOLD //粗体
Typeface.BOLD_ITALIC //粗斜体
Typeface.ITALIC //斜体
Typeface.NORMAL //常规
 

 

textView.setTypeface(Typeface.DEFAULT, Typeface.BOLD_ITALIC );

 

 //下划线 

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

//抗锯齿

textView.getPaint().setAntiAlias(true);

//中划线
textview.getPaint().setFlags(Paint. STRIKE_THRU_TEXT_FLAG); 

// 设置中划线并加清晰 
textview.setFlags(Paint. STRIKE_THRU_TEXT_FLAG|Paint.ANTI_ALIAS_FLAG);  

 

holder.odlte.setPaintFlags(Paint. STRIKE_THRU_TEXT_FLAG|Paint.ANTI_ALIAS_FLAG);

//字体加粗

textView.getPaint().setFakeBoldText(true);
