    1.Data Binding框架MVVM

    项目源码位置:AndroidProjects/DataBinding目录

    介绍

    • Data binding 在2015年7月发布的Android Studio v1.3.0 版本上引入,在2016年4月Android Studio v2.0.0 上正式支持。目前为止,Data Binding 已经支持双向绑定了。

    • Data Binding 解决了 Android UI 编程中的一个痛点,官方原生支持 MVVM 模型可以让我们在不改变既有代码框架的前提下,非常容易地使用这些新特性;

    • Databinding 是一个实现数据和UI绑定的框架,是一个实现 MVVM 模式的工具,有了 Data Binding,在Android中也可以很方便的实现MVVM开发模式。

    • Data Binding 是一个support库,最低支持到Android 2.1(API Level 7+)。

    • Data Binding 之前,我们不可避免地要编写大量的毫无营养的代码,如 findViewById()、setText(),setVisibility(),setEnabled() 或 setOnClickListener() 等,通过 Data Binding , 我们可以通过声明式布局以精简的代码来绑定应用程序逻辑和布局,这样就不用编写大量的毫无营养的代码了。

    Gradle配置:

    android {  
        dataBinding {
            enabled = true
        }
    }

    5.MultiChannelBuild

    项目源码位置:AndroidProjects/MultiChannelBuild目录

    介绍

    • Gradle多渠道打包
    • Gradle动态打包(包名,Logo,APP名称)
    • Gradle对生成APK名称重命名
    • Gradle签名配置
    • Gradle支持lambda
    • Gralde编译JDK1.8
    • Gradle存储库maven仓库设置

    Gradle常见命令

    • ./gradlew clean:清理删除build文件夹
    • ./gradlew build:检查依赖并编译打包debug和release版本
    • ./gradlew -v:版本号
    • ./gradlew assembleRelease:打包所有渠道release版本
    • ./gradlew assembleBaiduRelease:打某个渠道的release版本
    • ./gradlew assembleDebug:打包所有渠道debug版本
    • ./gradlew assembleBaiduDebug:打某个渠道的debug版本
    • ./gradlew installRelease:打包并安装Release模式包
      • ./gradlew installBaiduRelease:同上
    • ./gradlew uninstallRelease:卸载Release模式包
      • ./gradlew uninstallBaiduRelease:同上

    Gradle注意事项

    • linux下使用./gradlew
    • windows下使用gradlew
    • 打包后的apk文件在app–>build–>outputs—>apk
    • 使用gradlew时可能出现没有找到该命令,需要chmod 755 gradlew

    7.CustomTabs

    项目源码位置:AndroidProjects/CustomTabs目录

    介绍

    Chrome 浏览器现在已经成为 Android 原生系统的默认浏览器了。如果在您的应用中需要打开网页内容,之前的做法要么使用 WebView 或者 直接打开第三方浏览器来显示内容。典型的场景比如微信里面的大部分内容都是先在微信自己的 WebView 中显示,然后你可以选择菜单中的在浏览器中打开。而 Chrome 团队认为现在在应用中显示网页内容已经非常常见了,为了方便大家显示网页内容并且保存良好的用户体验,实现了这么一个功能。具体来说,如果您想在应用中打开一个网页,你可以通过 Chrome Custom Tabs 来打开 Chrome 浏览器的一个自定义 Tab 来显示该网页,你可以自定义这个 Tab 的一些属性来保持良好的用户体验,并且让用户感觉这个自定义 Tab 就是您应用的一部分。目前可以自定义如下内容:
    • ActionBar(也就是最上面的 Toolbar,网址一栏)的颜色
    • 自定义 Tab 的进入和退出过场动画
    • 在自定义 Tab 的 ActionBar 上添加自定义图标和菜单
    • 自定义返回图标
    • 自定义 Tab 可以通过回调接口来通知应用网页导航的情况
    • 性能更好,使用 Custom Tab 来打开网页的时候,还可以预先加载网页内容,这样当打开的时候,用户感觉非常快。
    • 生命周期管理,使用 Custom tab 可以和您的应用绑定一起,当用户在浏览网页的时候,您的应用也被认为是互动的程序,不会被系统杀死。
    • 可以共享 Chrome 浏览器的 Cookie ,这样用户就不用再登录一遍网站了。
    • 如果用户开启了 Chrome 的数据压缩功能,则一样可以使用
    • 和 Chrome 一样的自动补全功能
    • 只需点击左上角的返回按钮一次就可以返回您的应用中了
    • 每次用的都是最新版本的 Chrome
    何时选择使用 WebView 和 Chrome Custom Tabs 呢?
    • 如果你之前使用的不是 WebView ,则这种情况都应该用 Chrome Custom Tabs 来打开网页。如果你之前使用的是 WebView,则这里有两种情况来帮组您选择哪种情况更适合你:如果要显示的网页内容是由您自己控制的,并且网页内容需要和 Android 组件交互,比如通过 JavaScript 接口来调用 Android 系统的一些功能,这种情况下你还需要用 WebView 来实现;其他情况都可以用 Chrome Custom Tabs 来实现。

    • Chrome Custom Tabs 使用起来非常简单,简单的使用只需要一行代码,和直接调用系统浏览器显示网页没啥区别。通过简单的几项设定,就能让用户感觉浏览第三方网页就像您应用本身的功能一样。

    使用注意
    • 在CustomTabActivityHelper这个类里面的openCustomTab这个方法说明了一下:packageName is null打开自己定义的WebviewActivity的WebView,is not null打开一个自定义选项卡URL
    • 我通过2个手机测试发现
      • 谷歌亲儿子Nexus5:打开的是Chrome浏览器
      • 乐视X608:打开都是都是自己定义的WebviewActivity的WebView
    • 总结国内的ROM厂商已经干掉了Chrome,所以使用这个库意义不大。
