问题描述

我需要我的 textview 有不同颜色的文本.我还需要从 xml 代码中执行此操作，而不是从 java 代码中执行此操作.有没有人知道这样做的方法?谢谢

I need my textview to have different colored texts. Also I need to do this from xml code, non from java code. Is there anyone who knows some way for doing this? Thanks

例如我有一句话这是红色的".我需要单词是绿色的，而单词red是红色的.

e.g. I have sentence "This is red". I need words to be green, and word red to be red.

推荐答案

有三种方法可以改变 textview 中某些文本的颜色.

There are three ways to change the color of some text inside a textview.

1. 通过 strings.xml 文件在 (res>values) 中，使用标签 (<![CDATA[<p>This is green <font color='红色的十六进制值'>这是红色的</font>.</p>]]>) 然后在java代码中将textview声明为myTextView.setText(Html.fromHtml(getString(R.string.myText));

1. through strings.xml file in (res>values), using the tag (<![CDATA[<p>This is green <font color='hexvalue of red'>and this is red</font>.</p> ]]>) and then declaring the textview in java code as myTextView.setText(Html.fromHtml(getString(R.string.myText));

通过java代码，使用HTML标签String text = "<font color='hexvalue of green'>这是绿色</font><font color='hexvalue of red'>这是红色的</font>.";myTextView.setText(Html.fromHtml((text));

through java code, using the HTML tag String text = "<font color='hexvalue of green'>This is green</font> <font color='hexvalue of red'>and this is red</font>."; myTextView.setText(Html.fromHtml((text));

通过Spannable文本使用java代码.

through Spannable text using java code.

Spannable span = new SpannableString("My String");

span.setSpan(new ForegroundColorSpan(Color.RED), start_position, end_position,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

myTextView.setText(span);

如果还有其他方法可以做到这一点，那么我不知道它们.希望这会有所帮助

If there are other ways to do it then I'm not aware of them. Hope this helps
