目前，我有一个自定义视图，以9面片图像作为边框

该自定义视图在线性布局中放置了三次，因此看起来如下所示：

+------------------------+
|  CustomView            |
+------------------------+
|  CustomView            |
+------------------------+
|  CustomView            |
+------------------------+

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

我在视图中附加了一个单击事件侦听器，因此它是可单击的。但当我点击它时，我看不出我在点击它——颜色没有变化

所以，我想我应该附加一个“onPress”侦听器，然后更改视图的背景，但我找不到这样的侦听器

那么，我如何在视图上创建行为，以便看到它被按下？这通常是在Android中完成的，背景为绿色，表示现在正在按下它。

您可以为视图设置OnClickListener。单击视图时将调用的。但是，对于像在单击视图时更改背景这样简单的事情，您应该使用有状态的可绘制视图。它们是这样工作的，你可以制作3张9面片图像

就是你现在的正常背景

是用户使用轨迹球/d-pad选择视图时背景的样子

是用户单击视图时视图的外观

然后在drawable文件夹中创建一个新的xml文件。应该是这样的：

+------------------------+
|  CustomView            |
+------------------------+
|  CustomView            |
+------------------------+
|  CustomView            |
+------------------------+

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

然后，当您设置视图的背景时，将其设置为xml文件。

如果您在访问颜色时可能遇到问题，您可能希望将colors.xml添加到values文件夹中，其中包含一些您喜欢的颜色，如：

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <color name="background_pressed">#FFFF00</color> <!--yellow-->
 <color name="background_normal">#808000</color>    <!--olive-->
 <color name="background_focused">#0000FF</color>    <!--blue-->
</resources>

如果希望所有X11/w3c颜色代码都使用此处提供的post或just代码：

Thx for that=）因此，我有点接近解决方案。我没有试图找到“onPress”之类的东西，而是创建了3个不同的图像，将它们放在选择器XML文件中，然后附加选择器XML文件作为背景？我要试试那个=）谢谢！嗯，在[android:drawable=“@drawable/background_pressed”]上，我找不到我的drawable。如果我尝试用我的图像替换背景，它不会显示。我错过什么了吗？嗯，好像没用。。。这很正常-没有改变背景…我猜这与我在指定android:drawable=“…”时没有得到建议有关。您是在Eclipse中添加了XML还是仅仅添加到文件系统中？如果将其添加到文件系统中，则需要刷新eclipse文件夹。至于找不到drawable，您需要确保在xml中输入的名称与图像的名称完全相同，减去扩展名。您需要确保将视图设置为可单击和可聚焦。
