推荐答案

1 prepare 3图像按钮状态，并把它变成资源/绘制文件夹。

1. Prepare 3 images for button states, and put it into resource/drawable folder.

2 创建 RES /绘制/ 文件夹，一个新的XML文件，以任何你想要的名称，在这种情况下，我们只给一个名称为 my_button.xml 。确定该文件的按钮状态是属于哪个形象。

2. create a new XML file in res/drawable/ folder, in whatever name you want, in this case, we just give a name as my_button.xml. This file defined which button state is belong to which image.

现在，你可以通过这个ID是指这个按钮：@绘制/ my_button

Now, you can refer to this button via this Id : @drawable/my_button.

文件：RES /绘制/ my_button.xml

File : res/drawable/my_button.xml

使用这样的按钮图像 my_button.xml 中创建XML文件绘制文件夹

create xml file using the button image like this with my_button.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:drawable="@drawable/button_pressed_yellow"
      android:state_pressed="true" />
  <item android:drawable="@drawable/button_focused_orange"
      android:state_focused="true" />
<item android:drawable="@drawable/button_normal_green" />
</selector>

添加一个普通按钮，经由

add a normal button, and attach the background image to above "my_button" via

android:background:@drawable/my_button
