Android layout - alignment issue with ImageView
提问by Alnitak
I'm trying to put an image at the top left of a LinearLayout, but with the image border and padding taking up the whole of the width of the window.
我试图将图像放在 a 的左上角LinearLayout，但图像边框和填充占据了窗口的整个宽度。
If I try the XML below, I get my image with its border and a white background across the whole width of the page, exceptthat the image ends up centered, and doesn't move to the left.
如果我尝试下面的 XML，我会得到我的图像，它的边框和整个页面宽度的白色背景，除了图像最终居中，并且不会向左移动。
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:src="@drawable/banner"
android:background="@android:color/white"
android:padding="@dimen/d_8px"
/>
Is there some attribute that I've not yet discovered that forces the image to be left aligned within the ImageViewwhen the layout_widthis set to fill_parent?
是否有一些我尚未发现的属性会强制图像在设置为ImageView时左对齐？layout_widthfill_parent
In the meantime, I've worked around this by dropping the ImageViewinside another LinearLayoutand dropping an empty TextViewto its right that takes up the rest of the horizontal space.
与此同时，我解决了这个问题，把ImageView里面的另一个LinearLayout放下，TextView在它的右边放下一个空的，占据了其余的水平空间。

I was having a similar problem, to which you replied earlier today. Is this on "screen design" viewer provided by the Eclipse plugin side-by-side with the XML editor, or are you encountering the alignment problems when actually running the app? If the former, that appers to be a bug in the plugin, if the latter, try adding:
我遇到了类似的问题，你今天早些时候回复了。这是在 Eclipse 插件与 XML 编辑器并排提供的“屏幕设计”查看器上，还是在实际运行应用程序时遇到对齐问题？如果是前者，那似乎是插件中的一个错误，如果是后者，请尝试添加：
android:scaleType="fitStart"
From the documentation I've read, that seems to be the closest to what you need.
从我读过的文档来看，这似乎最接近您的需要。

Just configure your ImageView on your layout XML file with something like this:
只需使用以下内容在布局 XML 文件上配置 ImageView：
<ImageView android:id="@+id/imageViewName"
android:layout_width="90dp"
android:layout_height="90dp"
android:scaleType="fitStart"
android:adjustViewBounds="true"
android:padding="10dp"
android:src="@drawable/ic_contact_picture"
android:background="@color/white" />
