1、在android中经常看到设置的颜色为八位的十六进制的颜色值,例如:
1
2
3
|
public static final class color { public static final int lightblue= 0x7f040000 ; } |
或者在Java中tx.setTextColor(0xffff00f);
说明:
0xffff00ff是int类型的数据,分组一下0x|ff|ff00ff,0x表示颜色整数的标记,ff表示透明度,f00f表示色值,注意:0x后面ffff00ff必须是8位的颜色表示。
颜色和不透明度 (alpha) 值以十六进制表示法表示。任何一种颜色的值范围都是 0到 255(00到 ff)。
对于 alpha,00表示完全透明,ff表示完全不透明。
表达式顺序是“aabbggrr”,其中“aa=alpha”(00到ff);“bb=blue”(00到ff);“gg=green”(00到ff);“rr=red”(00到ff)。
2、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文件夹下新建一个color.xml,内容如下:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<drawable name="dkgray">#80808FF0</drawable>
<drawable name="yello">#F8F8FF00</drawable>
<drawable name="white">#FFFFFF</drawable>
<drawable name="darkgray">#938192</drawable>
<drawable name="lightgreen">#7cd12e</drawable>
<drawable name="black">#ff000000</drawable>
<drawable name="blue">#ff0000ff</drawable>
<drawable name="cyan">#ff00ffff</drawable>
<drawable name="gray">#ff888888</drawable>
<drawable name="green">#ff00ff00</drawable>
<drawable name="ltgray">#ffcccccc</drawable>
<drawable name="magenta">#ffff00ff</drawable>
<drawable name="red">#ffff0000</drawable>
<drawable name="transparent">#00000000</drawable>
<drawable name="yellow">#ffffff00</drawable>
</resources>
根据个人需要,颜色可以自行添加。
在Java中设置:
tx.setTextColor(tx.getResources().getColor(R.drawable.red));
color.xml中也可用color标签
<color name="red">#ffff0000</color>
java中设置相应改为:
tx.setTextColor(tx.getResources().getColor(R.color.red));
四、直接在xml的TextView中设置
android:textColor="#F8F8FF00" 或
android:textColor="#F8FF00"
3、另附Android中146种颜色对应的xml色值:
