AndroidLinearLayout:添加阴影边界LinearLayout - Android(安卓)LinearLayout : Add border with shadow around a l - android

主题：

我想创建相同的linearlayout这个边界为例:在这个例子中,我们可以看到,在linearlayout边境是不一样的。我如何使用xml可拉的创建这个文件?现在,我只能够创建一个简单的linearlayout边境周围是这样的:

原文：

I would like to create the same border of this linearlayout as example :

In this example, we can see that the border is not the same all around the linearLayout. How can i create this using an xml drawable file ?

For now, i have only able to create a simple border all around the linearlayout like this :

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">  <corners      android:radius="1dp"      android:topRightRadius="0dp"      android:bottomRightRadius="0dp"      android:bottomLeftRadius="0dp" />  <stroke      android:width="1dp"      android:color="#E3E3E1" />  <solid android:color="@color/blanc" />shape>

网友:您可以使用财产……创建一个XML文件与矩形等形状,颜色和阴影效果和设置它作为你的线性布局的背景。

(原文：you can use background property for that...create one XML file with shape like rectangle, color and shadow effect for it and set it as background for your linear layout..)

网友:使用中风的灰色边框和填充效果

(原文：use stroke for gray border and padding effect too)

网友:我认为,它的两个布局xml,一个是线性布局和内部是相对布局有填充

(原文：I think,that its two layout xml,say one is linear layout and inner is relative layout having padding)

楼主:@Prag创建这个xml文件的你能帮我吗?

(原文：@Prag's Could you help me for creating this xml file please ?)

网友:是的..等一下..

(原文：yeah..wait a minute..)

解决方案：
试试这个.. 原文：

Try this..

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <item>        <shape android:shape="rectangle">            <solid android:color="#CABBBBBB"/>            <corners android:radius="2dp" />        shape>    item>    <item        android:left="0dp"        android:right="0dp"        android:top="0dp"        android:bottom="2dp">        <shape android:shape="rectangle">            <solid android:color="@android:color/white"/>            <corners android:radius="2dp" />        shape>    item>layer-list>

楼主:@Hariharan谢谢!如何你的代码看起来好。但是,有一件事要做,我怎么能添加一个薄的边界(1dp)左边和右边的linearlayout吗?(为例)

(原文：@Hariharan Thanks a lot ! i tryed your code and it seems ok. But, there is one thing to do yet, how can i add a thin border (1dp) on the left and on the right of the linearlayout? (as the example))

网友:@wawanopoulos就取代Hariharan的答案。

(原文：@wawanopoulos Just replace "0dp" with "1dp" in Hariharan's answer.)

网友:您可以添加#EAEAEA颜色到父布局将问题图片一样

(原文：you can add #EAEAEA color to the parent layout so it will be just like the question image)

解决方案：
我得到最好的结果通过使用9块图形。您可以简单地创建一个个人9块图形通过使用以下编辑:http://inloop.github。io/shadow4android/例子:9块图形:结果:来源: 原文：

I get the best looking results by using a 9 patch graphic.

You can simply create an individual 9 patch graphic by using the following editor:http://inloop.github.io/shadow4android/

Example:

The 9 patch graphic:

The result:

The source:

"200dp"android:layout_height="200dp"android:orientation="vertical"android:background="@drawable/my_nine_patch"

网友:很好的方式,谢谢:-)

(原文：nice Way , Thanks :-))

网友:有用的链接谢谢@funcoder

(原文：Usefull link thanks @funcoder)

解决方案：
作为一种替代方法,您可以使用9块图像为背景对你的布局,允许更“自然”的阴影:结果:把图像在你的文件夹。确保文件扩展名,而不是顺便说一句,这是一个修改(减少到最小平方大小)的现有资源中发现19sdkAPI资源文件夹。我离开了红色标记,因为它们似乎并不是有害的,如draw9patch工具所示。[编辑]9补丁,如果你与他们从来没有任何关系。只需添加视图的背景。black-marked区域(左前)将拉伸(垂直、水平)。底部black-marked地区(右)定义“内容区”(可以添加文本或视图——你可以叫无名地区“填充”,如果你喜欢)。教程:http://radleymarx.com/blog/simple-guide-to-9-patch/ 原文：

As an alternative, you might use a 9 patch image as the background for your layout, allowing for more "natural" shadows:

Result:

Put the image in your /res/drawable folder.
Make sure the file extension is .9.png, not .png

By the way, this is a modified (reduced to the minimum square size) of an existing resource found in the API 19 sdk resources folder.
I left the red markers, since they don't seem to be harmful, as shown in the draw9patch tool.

[EDIT]

About 9 patches, in case you never had anything to do with them.

Simply add it as the background of your View.

The black-marked areas (left and top) will stretch (vertically, horizontally).
The black-marked areas (right, bottom) define the "content area" (where it's possible to add text or Views - you can call the unmarked regions "padding", if you like to).

楼主:@Der傀儡我从不使用9块,dos它是如何运作的吗?

(原文：@Der Golem I never use 9patch, how dos it works ?)

网友:伟大的9块资源!谢谢你！

解决方案：
好吧,我知道这是太迟了。但是我有相同的需求。我解决了1。首先创建一个xml文件(例如:border_shadow.xml)“可移动”文件夹,复制下面的代码。2。现在的布局要让阴影(例子:LinearLayout)添加这个android:背景,为我工作。原文：

okay, i know this is way too late. but i had the same requirement. i solved like this

1.First create a xml file (example: border_shadow.xml) in "drawable" folder and copy the below code into it.

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android"android:shape="rectangle" ><item>    <shape>                <stroke            android:width="2dp"            android:color="#7000" />                <padding            android:bottom="2dp"            android:left="2dp"            android:right="-1dp"            android:top="-1dp" />        <corners android:radius="3dp" />    shape>item><item>    <shape>        <solid android:color="#fff" />        <corners android:radius="3dp" />    shape>item>

2.now on the layout where you want the shadow(example: LinearLayout) add this in android:background

<LinearLayout    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:layout_margin="8dip"    android:background="@drawable/border_shadow"    android:orientation="vertical">

and that worked for me.

解决方案：
这就是为什么CardView存在。CardView|Android开发者只是FrameLayout支持海拔pre-lollipop设备。使用这个您需要添加依赖关系: 原文：

That's why CardView exists. CardView | Android Developers
It's just a FrameLayout that supports elevation in pre-lollipop devices.

<android.support.v7.widget.CardView    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    app:cardUseCompatPadding="true"    app:cardElevation="4dp"    app:cardCornerRadius="3dp" >    android.support.v7.widget.CardView>

To use this you need to add dependency to build.gradle:

compile 'com.android.support:cardview-v7:23.+'
