使一段字符串显示不同的颜色

一种：字体颜色改变

 

     String appname= info.appname;   //字符串内容
         
        int start = appname.indexOf(mKeywordname); //mKeywordname需要改变颜色的字符串

          
        ColorStateList redColors = ColorStateList.valueOf(0xFF960c0c);//0xFF960c0c颜色值
        SpannableStringBuilder spanBuilder =new SpannableStringBuilder(appname);
        spanBuilder.setSpan(new TextAppearanceSpan(null, 0, 0, redColors, null), start, start +mKeywordname.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  
       searchAppItem.mSearchAppListAppNameTextView.setText(spanBuilder); 

 

        
  二种：字体背景改变   

   
    SpannableStringBuilder style = new SpannableStringBuilder(appname);  
      style.setSpan(new BackgroundColorSpan(Color.RED), start, start +mKeywordname.length(),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);          
        searchAppItem.mSearchAppListAppNameTextView.setText(spanBuilder);
