从csv字符串搜索sql(sql search from csv string)

 您可以使用SpannableString和SpannableStringBuilder 。 
 
SpannableStringBuilder ssb = new SpannableStringBuilder("25 415,50 XX");
var realtiveSizeSpan = new RelativeSizeSpan(1.5f);
ssb.SetSpan(realtiveSizeSpan, 0, 6, 0);
textView.TextFormatted = ssb;
 
 这为内容中的给定字符范围设置了“格式”。 SetSpan设置子字符串的格式，这里我从索引0设置6个字符。 请注意，您需要将值分配给TextFormatted属性而不是Text 。 
 
 另一种方法是将两个不同格式的TextView控件彼此相邻（例如，包含在Horizontal LinearLayout中），但这种解决方案不太可靠，并且不能确保文本完全位于一条直线上。 

You can use the SpannableString and SpannableStringBuilder.
 
SpannableStringBuilder ssb = new SpannableStringBuilder("25 415,50 XX");
var realtiveSizeSpan = new RelativeSizeSpan(1.5f);
ssb.SetSpan(realtiveSizeSpan, 0, 6, 0);
textView.TextFormatted = ssb;
 
This sets a "formatting" for a given character range in the content. The SetSpan sets a formatting of a substring, here I set it from index 0, for 6 characters. Note that you need to assigne the value to the TextFormatted property instead of Text.
 
The alternative would be to have two differently formatted TextView controls next to each other (wrapped in a Horizontal LinearLayout for example), but such solution is less reliable and does not ensure that the texts will lay exactly in one straight line.
