如何在Android API低21中使用矢量drawable？ [英] How to use vector drawables in Android API lower 21?

问题描述

我正在开发一个Android项目，我选择了< vector> 来显示图标，因为它具有适应性和动态性，但是，我只能在设备上运行此应用运行Android，具有API 21或更高版本。我的问题是如何在较低的Android版本（即API 14或其类型）上使用< vector> 。谢谢！

I am working on an Android project and I chose <vector> to display icon because it is adaptable and dynamically, however, I just can run this app on devices running Android, which have API 21 or higher. My question is how can I use <vector> on lower Android version i.e. API 14 or kind of. Thanks!

<!-- drawable/ic_android_debug_bridge.xmlxml -->
<vector xmlns:android="http://schemas.android.com/apk/res/android"

推荐答案

Vector Drawables是现在向后兼容，只需将您的gradle版本升级到1.4.0-beta3或更高版本，然后升级您的IDE：

Vector Drawables are now backward compatible, it's just a matter of upgrading your gradle version to 1.4.0-beta3 or higher, and upgrade your IDE :

我们也非常高兴为Android Studio 1.4中的vector
资产提供向后兼容性。一旦你的res / drawable在
中有了一个vectorDrawable图像，Gradle插件就会在构建时间内为API等级20及以下版本自动生成
栅格PNG图像。这个
意味着您只需要为
应用项目更新和维护矢量资产，Android Studio就可以处理图像转换
流程。

We are also excited to offer backwards compatibility for your vector assets in Android Studio 1.4. Once you have a vectorDrawable image in your res/drawable, the Gradle plugin will automatically generate raster PNG images for API level 20 and below during build time. This means you only need to update and maintain your vector asset for your app project and Android Studio can take care of image conversion process.
