Android中TextView多种颜色的设置

一、概述

项目中需要实现在一行文本中实现多种文本的颜色，参考（见文章结尾）网友的资料后实现。现总结方法，方便自己记忆和以后的使用。

二、实现过程

方法一：

tvSpan = (TextView) findViewById(R.id.tv_span);
SpannableStringBuilder span = new SpannableStringBuilder("彩虹的颜色是：红橙黄绿青蓝紫。");
span.setSpan(new ForegroundColorSpan(Color.GRAY), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.RED), 7, 8, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.parseColor("#FCCC2C")), 8, 9, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.parseColor("#FDFD00")), 9, 10, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.GREEN), 10, 11, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.parseColor("#01FFFF")), 11, 12, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.BLUE), 12, 13, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.parseColor("#A700FF")), 13, 14, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new ForegroundColorSpan(Color.GREEN), 14, 15, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
tvSpan.setText(span);

方法二：（推荐）

TextView tvText = (TextView) findViewById(R.id.tv_text);
String text = "<font color = '#707070'> 彩虹的颜色是：</font>"
+ "<font color = '#ff0000'>红</font>"
+ "<font color = '#FCCC2C'>橙</font>"
+ "<font color = '#FDFD00'>黄</font>"
+ "<font color = '#00ff00'>绿</font>"
+ "<font color = '#01FFFF'>青</font>"
+ "<font color = '#0000ff'>蓝</font>"
+ "<font color = '#A700FF'>紫</font>"
+ "<font color = '#00ff00'>。</font>";
tvText.setText(Html.fromHtml(text));



效果如下
