Android的布局元素设置背景颜色
我想，有些克隆的活动from一组在Android的UI设计的幻灯片。但是我有一个非常简单的任务的一个问题。
I am trying to, somewhat clone the design of an activity from a set of slides on Android UI design. However I am having a problem with a very simple task.
我已经创建了布局，显示的图像，以及标题是的TextView 在 RelativeLayout的。现在我想更改 RelativeLayout的的背景颜色，但我似乎无法弄清楚如何。
I have created the layout as shown in the image, and the header is a TextView in a RelativeLayout. Now I wish to change the background colour of the RelativeLayout, however I cannot seem to figure out how.
我知道我可以设置安卓背景属性在XML文件中的 RelativeLayout的标签，但什么我将它设置为？我想定义一个新的颜色，我可以在多个地方使用。它是一个绘制或字符串？
I know I can set the android:background property in the RelativeLayout tag in the XML file, but what do I set it to? I want to define a new colour that I can use in multiple places. Is it a drawable or a string?
此外我希望那里是一个非常简单的方法来此从Eclipse的Android UI设计师，我必须失去了在？
Additionally I would expect there to be a very simple way to this from within the Eclipse Android UI designer that I must be missing?
目前我沮丧了一下，因为这应该是与点击几下最大执行的活动。因此，任何帮助pciated非常AP $ P $。 ：）
I am a bit frustrated currently, as this should be an activity that is performed with a few clicks at maximum. So any help is very appreciated. :)
您可以使用简单的颜色资源，里面的 RES /价值/ colors.xml通常指定。
<color name="red">#ffff0000</color>
和通过用这个机器人：背景=@色/红色。这种颜色可以使用任何其他地方也一样，例如作为文本的颜色。在XML参考用同样的方式，或通过 getResources得到它在code（）。的getColor（R.color.red）。
and use this via android:background="@color/red". This color can be used anywhere else too, e.g. as a text color. Reference it in XML the same way, or get it in code via getResources().getColor(R.color.red).
您也可以使用任何绘制资源为背景，用机器人：背景=@可绘制/ mydrawable这个（这意味着9patch可绘，正常位图，形状可绘制。）
You can also use any drawable resource as a background, use android:background="@drawable/mydrawable" for this (that means 9patch drawables, normal bitmaps, shape drawables, ..).
