margin 设置为 textView 的第一行
我只想为 TextView 的第一行设置起始边距（不是每个段落的第一行）？我使用了以下代码：
SpannableString s = new SpannableString("this is a test"+"\n"+"this is a test");
s.setSpan(new android.text.style.LeadingMarginSpan.Standard(30, 0), 0, s.length(), 0);
textView .setText(s);
这里为该段落的所有行设置了起始边距。我不希望这样。我希望起始边距仅应用于第一行..请帮助..
I want to set start margin only for the first line of TextView (Not first line of each paragraph)? I have used the following code:
SpannableString s = new SpannableString("this is a test"+"\n"+"this is a test");
s.setSpan(new android.text.style.LeadingMarginSpan.Standard(30, 0), 0, s.length(), 0);
textView .setText(s);
Here start margin is getting set for all lines of the Paragraph.. I don't want that. I want start margin to be applied for first line only.. Pls help..

您实际上已经回答了自己的问题。
您所需要做的就是将跨度长度设置为
1而不是s.length()。这样，边距将仅应用于第一段。
You actually already answered your own question.
All you need to do is to set span lenght to
1instead ofs.length().That way margin will only be applied to the first paragraph.
正如这里所建议的，我也认为最好的解决方案是在开头简单地添加一些空格。如果您只需要
TextView第一行的边距空间，我不认为您需要做一些真正高级的事情。如果稍后需要更改或使用 TextView 中的文本，则可以使用
substring()方法仅获取字符串的一部分，即s.substring( 2、s.length());这不是一个完美的解决方案，但我认为它可以。
As it has been suggested here, I also think the best solution is to simply add a few spaces at the beginning. If you only need the margin space at the very first line of the
TextView, I don't see any reason why you'd need to do something really advanced.If you need to change or use the text in the TextView at a later point, you can just use the
substring()method to get only a part of the string, i.e.s.substring(2, s.length());It's not a perfect solution, but I think it'll do.
