      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain

      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,

      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

      boilerplate notice, with the fields enclosed by brackets "[]"
      replaced with your own identifying information. (Don't include

# CardviewFix 简书地址 [https://www.jianshu.com/p/8c8b2708bdb4]

##### 原生的CardView虽然好,但是公司UI设计必须修改阴影颜色
这个库是基于google官方库,所以基本属性相同,增加三个属性,暂时只支持xml配置,分别是`startColor`,`endColor`,`topDelta`,意思是支持修改渐变颜色值,而`topDelta`是1.0.1版本加进来支持修改上下阴影比例的,取值范围是-1到1的浮点值,具体效果可以看截图


>demo在另一个项目https://github.com/bigmanLau/Tablayout 去吧比卡丘



依赖方式
Step 1. Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:

````
	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}
````
Step 2. Add the dependency
````
dependencies {
	        implementation 'com.github.bigmanLau:CardviewFix:1.0.3'
	}
````

效果图如下
![1.png](https://upload-images.jianshu.io/upload_images/12262980-a456f38c9faabf0d.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

第一个item就是topDelta等于-1的效果,第二个item是topDelta等于0的效果,第三个item是topDelta等于1的效果

>*注意:这个偏移量和cardCornerRadius的值有关,最大值就是cardCornerRadius的值,其实就是设置cardCornerRadius的百分比*

##### 有些同学不喜欢我贴代码,那么直接上我的github地址去看

具体原理看代码 
[github地址] (https://github.com/bigmanLau/CardviewFix)

>注意问题
>1. 如果出现黑边  需要修改主题为` <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">`
>2.其他属性用法和原生的一样
>3.如果出现白边请用cardview的请设置` app:cardPreventCornerOverlap="false"`

/**
 * A FrameLayout with a rounded corner background and shadow.
 *
 *
 * CardView uses `elevation` property on Lollipop for shadows and falls back to a
 * custom emulated shadow implementation on older platforms.
 *
 *
 * Due to expensive nature of rounded corner clipping, on platforms before Lollipop, CardView does
 * not clip its children that intersect with rounded corners. Instead, it adds padding to avoid such
 * intersection (See [.setPreventCornerOverlap] to change this behavior).
 *
 *
 * Before Lollipop, CardView adds padding to its content and draws shadows to that area. This
 * padding amount is equal to `maxCardElevation + (1 - cos45) * cornerRadius` on the
 * sides and `maxCardElevation * 1.5 + (1 - cos45) * cornerRadius` on top and bottom.
 *
 *
 * Since padding is used to offset content for shadows, you cannot set padding on CardView.
 * Instead, you can use content padding attributes in XML or
 * [.setContentPadding] in code to set the padding between the edges of
 * the CardView and children of CardView.
 *
 *
 * Note that, if you specify exact dimensions for the CardView, because of the shadows, its content
 * area will be different between platforms before Lollipop and after Lollipop. By using api version
 * specific resource values, you can avoid these changes. Alternatively, If you want CardView to add
 * inner padding on platforms Lollipop and after as well, you can call
 * [.setUseCompatPadding] and pass `true`.
 *
 *
 * To change CardView's elevation in a backward compatible way, use
 * [.setCardElevation]. CardView will use elevation API on Lollipop and before
 * Lollipop, it will change the shadow size. To avoid moving the View while shadow size is changing,
 * shadow size is clamped by [.getMaxCardElevation]. If you want to change elevation
 * dynamically, you should call [.setMaxCardElevation] when CardView is initialized.
