2019年学android

重点 (Top highlight)

It’s been over a year since I released my last article about Android libraries. Now, I’m back with a summary of awesome libraries and projects released (or heavily refreshed) in 2019. They’re not in ranked order. Let’s begin!

自从我发布有关Android库的上一篇文章以来已有一年多了。现在，我返回了有关2019年发布(或大量刷新)的优秀库和项目的摘要。它们的排名不高。让我们开始！

1.线圈 (1. Coil)

Coil is a really fresh approach to image loading on Android.The acronym of this library stands for coroutine image loader. The library is fast, lightweight (~1500 methods), easy to use, and modern, especially in comparison to libraries like Glide, Picasso, or Fresco. It supports GIFs and SVGs and can do four default transformations: blur, circle crop, grayscale, and rounded corners.

Coil是Android上一种非常新颖的图像加载方法。该库的缩写代表协程图像加载器 。该库快速，轻量(约1500种方法)，易于使用且具有现代性，尤其是与Glide，Picasso或Fresco之类的库相比。它支持GIF和SVG，并且可以执行四个默认转换：模糊，圆形裁剪，灰度和圆角。

Code example below:

下面的代码示例：

imageView.load(“https://www.example.com/image.jpg") {
 crossfade(true)
 placeholder(R.drawable.image)
 transformations(CircleCropTransformation())
}

The documentation and code samples are more than enough to start using it without any hesitation. Everything is clear and easy. Currently the lib is in a version 0.9.5.

文档和代码示例足以毫不犹豫地开始使用它。一切都清晰而轻松。目前，该库的版本为0.9.5。

Fun fact: During the last three months, I interviewed 14 candidates, and no one knew about Coil. Be cool, and impress your interviewer by mentioning Coil. Even Google made a mistake about an author when they wrote about Coil in their “Loading Large Bitmaps Efficiently” article. Regardless, it’s fixed now.

有趣的事实：在过去三个月中，我采访了14位候选人，但没人知道Coil。保持冷静，并提及Coil，打动您的面试官。甚至Google在“ 高效地加载大位图 ”一文中提到Coil时，也对作者犯了一个错误。无论如何，它现在已修复。

2. MultiSearchView (2. MultiSearchView)

This library has a really cool approach to an animated search view.

该库具有一种非常酷的动画搜索视图方法。

It’s easy to set up and is customisable — you can add your style’s set under styles.xml.

它易于设置且可自定义-您可以在styles.xml下添加样式集。

The README is quite short, but I believe it’s OK. This is version 0.1, so I wouldn’t use it in production. Rather, I’d treat it like a great lib for a playground project to have some fun in.

自述文件很短，但我认为可以。这是版本0.1，所以我不会在生产中使用它。相反，我将其视为一个游乐场项目的有趣的自由库。

It was released under the Apache 2.0 license.

它是根据Apache 2.0许可发布的。

3. CalendarView (3. CalendarView)

This is a highly customizable calendar library, powered by RecyclerView.

这是一个高度可定制的日历库，由RecyclerView提供支持。

It has lots of features:

Custom calendar view
自定义日历视图
Horizontal- or vertical-scrolling mode
水平或垂直滚动模式
Fully customizable views
完全可定制的视图
And much more
以及更多

The documentation is really comprehensive and full of examples. What’s more, there’s a sample app that showcases every feature of the library. It’s written 100% in Kotlin and released under MIT license. If you need a calendar view in your application, I believe this one is good to go, despite the fact it’s still in version 0.3.2 (at the time of this article).

该文档确实非常全面，并包含许多示例。此外，有一个示例应用程序展示了库的所有功能。它是用Kotlin写的100％，并根据MIT许可发布。如果您需要在应用程序中使用日历视图，尽管它仍处于0.3.2版中(在本文撰写之时)，但我相信这样做是不错的选择。

4.气泡导航 (4. Bubble Navigation)

This is a fresh approach to a navigation — a light-weight library to easily make beautiful navigation bars with a ton of customisation options.

这是一种新颖的导航方法-轻巧的库，可通过大量自定义选项轻松制作精美的导航栏。

It has many cool features:

两种类型的NavigationView适用于不同的用例： BubbleNavigationConstraintView (支持spread ， inside和packed模式)和BubbleNavigationLinearView (允许平均分配，使用权重或打包模式)
It’s highly customizable
高度可定制
You can add badges, and it has the BubbleToggleView to create new UI components, other than just the navigation
您可以添加徽章，它具有BubbleToggleView来创建新的UI组件，而不仅仅是导航

The README file is quite detailed and explains how to use all of the components to achieve this cool-looking UI. You can always check the sample app. The project was released under the Apache 2.0 license.

这不是一个库，而是一个展示应用程序，用于展示使用和不使用MotionLayout实现的高级UI动画。

It’s a really interesting project — with two correlated articles on Medium:

这是一个非常有趣的项目-关于Medium的两篇相关文章：

“Complex UI/Animations on Android”
“ Android上的复杂UI /动画 ”
“Complex UI/Animations on Android — featuring MotionLayout”
“ Android上的复杂UI /动画-具有MotionLayout ”

Worthy reading for sure!

肯定值得一读！

6. SmoothBottomBar (6. SmoothBottomBar)

SmoothBottomBar describes itself as “a lightweight Android material bottom navigation bar library.”

SmoothBottomBar将自己描述为“轻量级的Android材质底部导航栏库”。

11.瞥见 (11. Glimpse)

Let’s stay with cropping tools for a little bit. Glimpse is a content-aware cropping library for Android, and it’s awesome that these kinds of libraries are created and open sourced.

让我们继续使用裁剪工具。 Glimpse是适用于Android的内容感知裁剪库，并且创建并开源了这些库真是太棒了。

As you can see above, instead of center-cropping images blindly, Glimpse catches the right spot.

正如您在上方看到的那样，Glimpse不会盲目地对图像进行中心裁剪，而是抓住了正确的位置。

But how? It uses TensorFlow Lite underneath with a proper model. What’s also great is it supports Coil and Glide. You should check out the README file for sure because it’s really extensive, and you’ll learn a lot. It’s released under the Apache 2.0 license. Maybe it’s not ready for production yet, but I still highly recommend it.

但是如何？它在适当的模型下使用TensorFlow Lite 。很棒的地方是它支持Coil和Glide。您应该确定检查README文件，因为它确实很广泛，并且您会学到很多东西。它是根据Apache 2.0许可发布的。也许它还没有准备好生产，但是我仍然强烈推荐它。

12. RubberPicker (12. RubberPicker)

This is an animated and interesting approach to SeekBars.

这是SeekBars一种生动有趣的方法。

The RubberPicker library contains the RubberSeekBar and RubberRangePicker, inspired by Cuberto's rubber-range-picker for iOS.

每个人都知道商店。至少，他们应该。目前，我们处于这个用于异步数据加载和缓存的出色库的第四次迭代中。根据自述文件：

“A Store is a class that simplifies fetching, sharing, storage, and retrieval of data in your application. A Store is similar to the Repository pattern while exposing an API built with Coroutines that adheres to a unidirectional data flow.

“ Store是一类，可简化应用程序中数据的获取，共享，存储和检索。 Store类似于存储库模式，同时公开了使用Coroutines构建的，遵循单向数据流的API。

Store provides a level of abstraction between UI elements and data operations.”

Store提供了UI元素和数据操作之间的抽象层次。”

You can learm more about Store in the last Android Developers Backstage podcast: “Episode 132: Storing data with Store.”

20.轮廓 (20. Contour)

Contour is a typesafe, Kotlin-first API for complex layouts on Android from Square Engineering.

Contour是Square Developer上用于Android上复杂布局的类型安全的Kotlin优先API。

According to their GitHub page:

根据他们的GitHub页面：

“Contour aims to be the thinnest possible wrapper around Android’s layout APIs. It allows you to build compound views in pure Kotlin without using opaque layout rules — but instead by hooking into the layout phase yourself. The best comparison for Contour would be to ConstraintLayout — but instead of defining constraints in XML you actually provide them as executable lambdas.”

“ Contour旨在成为Android布局API的最薄包装。它允许您在不使用不透明布局规则的情况下，在纯Kotlin中构建复合视图，而是自己自己进入布局阶段。 Contour的最佳比较将是ConstraintLayout，但实际上不是将约束定义为XML，而是将它们提供为可执行lambda。”

This is a really interesting idea, especially since this library tries to deprecate the old XML-Android approach. The documentation is really good, but please remember that:

这是一个非常有趣的想法，尤其是因为该库试图弃用旧的XML-Android方法。该文档非常好，但是请记住：

“This project is currently experimental and the API subject to breaking changes without notice.”

“该项目目前处于试验阶段，API如有更改，恕不另行通知。”
