Add Frame or Border to ImageView and Drop-Shadow
提问by Shrikant
What I'm trying to do will work better with an example image. As you can see below I have a grey background, ontop of that sits a container with some padding containing an image. The container also has a slight dropshadow to it.
我正在尝试做的事情会更好地与示例图像一起使用。正如你在下面看到的，我有一个灰色的背景，上面是一个容器，里面有一些包含图像的填充。容器也有轻微的阴影。
What I want to know, is if there's so non-painstaking way of doing this in my layout.xml? In a normal HTML document this would've been easy. But since this is for a mobile app and for a number of screen resolutions and so on, it's proving a bit difficult.
我想知道的是，在我的 layout.xml 中是否有这么简单的方法？在普通的 HTML 文档中，这很容易。但由于这是针对移动应用程序和许多屏幕分辨率等，事实证明这有点困难。
Any advice?
有什么建议吗？
Edit: I eventually settled using a 9patch image. Everyting went really smooth in the creation of it but when I actually use it in my app I see these dark stripes on the right and bottom of the image. The dropshadow seems to work, it's a very light dropshadow.. but those darn stripes??
编辑：我最终使用 9patch 图像解决了问题。一切在创建过程中都非常顺利，但是当我在我的应用程序中实际使用它时，我会在图像的右侧和底部看到这些深色条纹。阴影似乎有效，它是一个非常轻的阴影……但是那些该死的条纹？？

You can provide a border to a view by writing an xml file (say editBorder.xml) in drawable folder:
您可以通过在 drawable 文件夹中编写一个 xml 文件（例如 editBorder.xml）来为视图提供边框：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke
android:width="5dp"
android:color="#EBDDE2" />
<padding
android:bottom="2dp"
android:left="2dp"
android:right="2dp"
android:top="4dp" />
<gradient
android:centerColor="@color/white"
android:endColor="@color/white"
android:startColor="@color/white" />
<corners android:radius="8dp" />
</shape>
and to provide this border, use statement in ImageView as android:background="@drawable/editBorder"
并提供此边框，在 ImageView 中使用语句作为 android:background="@drawable/editBorder"
This should solve your problem. :)
这应该可以解决您的问题。:)

Create a blank white frame with drop shadow(Photoshop recommended).
创建一个带有阴影的空白白框（推荐使用 Photoshop）。
So just do this
所以就这样做
<ImageView android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/image"
android:background="@drawable/whiteFrame"
android:padding="10dp" >
</ImageView>
