Android中设置文本颜色的四种方法：

一、利用系统自带的颜色类

tx.setTextColor(android.graphics.Color.RED);

二、数字颜色表示

tx.setTextColor(0xffff00f);

三、自定义颜色

在工程目录values文件夹下的color.xml（没有自己新建）。

四、直接在xml的TextView中设置

android:textColor=”#F8F8FF00” 或

android:textColor=”#F8FF00”

这里主要是列出第三条：
在color.xml里面的配置是这样的：

这样做的好处就是常用的颜色可以直接调用，既方便的开发，也方便做统一的修改和代码的维护。体现了复用性的价值。

当然如果用的是AS（android studio）的话，在编辑页左边数列对于颜色是由提示显示的。系统也提供的可以自有修改和定义颜色的功能，直接用鼠标点击，就会弹出修改的颜色功能窗。
