Android向量相容性 [英] Android vector compatibility
问题描述
我想开始在我使用的应用程序中使用矢量作为图标，但是不确定如何处理兼容性
I'd like to start using vectors for the icons with in the apps I do, but not sure how to deal with the compatibility
我对任何第三方兼容库都不感兴趣，很高兴等待google版本(此处提及
I'm not interested in any of the third party compat libraries and happy to wait for googles version (Mentioned here VectorDrawable - is it available somehow for pre-Lollipop versions of Android?).
所以基本上到目前为止，我很高兴继续获得每个分辨率的图像以及Lollipop的其他图像.如果设备高于21，则将使用矢量，否则将退回到标准png.
So basically for now I'm happy to continue to have the images per resolution as well as an additional for > Lollipop. If the device is higher than 21 it will use the vector otherwise it will fall back to the standard png's.
我可以将矢量放置在drawable-v21文件夹中，但是drawable- [dpi]文件夹优先于版本，这意味着不使用矢量.
I can have the vector in a drawable-v21 folder, but the drawable-[dpi] folder takes precedence over the version, meaning the vector isn't used.
我希望使用该向量，以便当compat可用时，我可以简单地删除所有png并知道这些向量是可以的，因为我已经能够在运行Lollipop的设备上对其进行测试.
I'm hoping the vector is used so that when the compat comes available I can simply delete all the png's and know the vectors will be ok as I have been able to test them on a device running Lollipop.
推荐答案
从Android 5.0(API级别21)开始，您可以在应用程序中使用vector drawable.您可以使用新的Android Studio工具，称为:Vector Asset Studio.它会自动处理旧版本的PNG.请参阅下面的链接以获取完整说明:
From Android 5.0 (API level 21) you can use vector drawable in your app. You can use new Android Studio tool called: Vector Asset Studio. It handles PNG making for older versions automatically. See link below for a complete explanation:
