android中的android api 4.1中的按钮点击后背景颜色如何变化？

Question

我想知道按钮点击背景颜色如何在这里改变,它发生的次数超过按钮大小.任何人都可以告诉我背景颜色来自哪里？在android api 4.1里面,在路径:Android API-res-layout-log_text_box_1.xml文件看起来像这样.

此行为是为河洛主题默认的Android风格的按钮,选择使用此类按钮位于路径到SDK \平台\ Android的16\DATA \水库\绘制与名称,如:btn_default_holo_dark.xml和btn_default_holo_light.xml

用于第一个选择器的drawable是:

btn_default_normal_holo_dark.9

btn_default_disabled_holo_dark.9

btn_default_disabled_focused_holo_dark.9

btn_default_focused_holo_dark.9

btn_default_pressed_holo_dark.9

最后9个补丁图像是负责超出按钮边框效果的图像,希望这是您正在寻找的.
