改变Textview中个别字体的属性

ColorStateList redColors = ColorStateList.valueOf(Color.parseColor("#fc994a"));//这设置颜色

SpannableStringBuilder spanBuilder = new SpannableStringBuilder(textA);//textA:原始字符串

int indexStart=hospitalName.indexOf(key);//key:想要改变的部分字符串

int indexEnd=indexStart+key.length();

//style 为0 即是正常的，还有Typeface.BOLD(粗体) Typeface.ITALIC(斜体)等

//size 为0 即采用原始的正常的 size大小

if (indexStart>=0&&indexEnd>=0){

DensityUtil densityUtil=new DensityUtil();

spanBuilder.setSpan(new TextAppearanceSpan(null, 0,densityUtil.dip2px(context,17) , redColors, null), indexStart, indexEnd, Spanned.SPAN_EXCLUSIVE_INCLUSIVE);

.setText(spanBuilder);
