If your image lends itself to being converted to a scalable 9-patch image, then doing that would cause the background to scale around the TextView.

You can create a <code>FrameLayout</code> and put an <code>ImageView</code> and your <code>LinearLayout</code> there. So you'll be able to configure the layout of your background image.

blocks|key|2131834|text|我相信这里最好的解决方案是将android:clipToPadding=设置为“true”。这样做的目的是排除主布局的填充，并将您的布局包装到其子布局。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2131835|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I believe the best solution here is to set android:clipToPadding="true". What this does is excludes the padding for the main layout and wraps your layout to its children.

blocks|key|5147104|text|好吧，这个帖子有点老了，但我有一个解决方案，也许有一天有人会发现它很有用。我认为Android在缩小大图像方面有问题，所以LinearLayout的大小最终会被背景可绘制的位图增大，而ImageView最终会强制增大父容器的大小。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5147105|除非您使用相对布局。您可以将ImageView设置为相对于LinearLayout的位置，即使ImageView位于父级中的布局之后。我的解决方案看起来像这样：|5147106|<?xml+version="1.0"+encoding="utf-8"?>

</RelativeLayout>|code-block|syntax|javascript|5147107|我在不同的显示尺寸和操作系统版本上尝试了一下，看起来效果很好。请注意，LinearLayout中的填充是为背景图像图形中的阴影边框留出空间的技巧。LinearLayout不需要任何相对定位，因为假设了左上角。|5147108|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

OK, so this thread is a little old, but I have a solution that someone might someday find useful. I think Android has problems scaling large images down, so the LinearLayout size ends up getting bumped by the background drawable bitmap, and the ImageView ends up forcing up the size of the parent container.

Unless you use a relative layout. You can make the ImageView relative to the position of the LinearLayout, even when the ImageView is behind the layout in the parent. My solution looks something like this:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout 
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 xmlns:android="http://schemas.android.com/apk/res/android"&gt;
&lt;ImageView
 android:src="@drawable/activation_popup"
 android:scaleType="fitXY"
 android:layout_width="0dp"
 android:layout_height="0dp"
 android:layout_alignTop="@+id/activation_layout"
 android:layout_alignBottom="@id/activation_layout"
 android:layout_alignLeft="@id/activation_layout"
 android:layout_alignRight="@id/activation_layout"
 android:contentDescription="@string/act_code_label" /&gt;
&lt;LinearLayout
 android:id="@id/activation_layout"
 android:clipToPadding="true"
 android:padding="25dp"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:orientation="vertical" &gt;
 &lt;!-- LinearLayout wraps a bunch of smallish views here --&gt;
&lt;/LinearLayout&gt;
&lt;/RelativeLayout&gt;
</code></pre>

I tried this on a top of display sizes and OS versions, seems to work great. Note that the padding in the LinearLayout is a trick to make space for a shadow border in the background image graphic. The LinearLayout doesn't need any relative positioning because top left is assumed.

blocks|key|3031283|text|这是因为Android视图根据其背景可绘制大小计算其最小大小。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3031284|在另一篇文章中查看my+answer+here，这篇文章涵盖了相同的问题，这将帮助你实现布局配置。|offset|length|3031285|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/31278522/4052043^0|0|9|E|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

This happens because the Android view calculates its minimum size based on its background drawable size.

Check <a href="https://stackoverflow.com/a/31278522/4052043">my answer here</a> in this another post which covers the same problem which will help you to achieve your layout configuration.

How can I get a LinearLayout (or any other ViewGroup) to assume the size of it's child views rather than assuming the size of the background image?

<pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:background="@drawable/large_image300x300pix"&gt;

 &lt;TextView android:id="@+id/TextView01" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:text="Hello world!"/&gt;
&lt;/LinearLayout&gt;
</code></pre>

The linear layout becomes the same size as the background image.
