android 使用uimode android 使用建模文件

在android开发中使用MVP模式进行开发最烦的就是要创建model，presenter，view等等一系列文件。这大大的降低了开发效率，那么有没有方法能够解决这个问题呢？这里不得不感谢AS的伟大，他为我们提供了这一类事插件的功能。

在创建Activity的过程中这一张图片大家一定很熟悉

当我们点击Empty Activity时给我们创建了一个带XML布局的Activity，并且帮我们在清单文件中注册了Activity。可能大家之前只用了这个功能，却没有想过为什么他能这样帮我们创建好这些个文件。没错今天要说的这个解决办法就是要依赖这个AS提供的可扩展办法。

我这里用的是Mac系统，Windows系统请自行找到位置

打开应用程序->右击显示包内容........按照上面图片底部的路径找到那个文件夹。是不是很惊喜，哈哈哈哈哈。原来我们在创建Activity是可以选择的模版都在这里。既然找到了根源我们就来看一下他的庐山真面目。

发现一个模版主要就是由上面那几个文件构成。

简单说明一下

globals文件主要是配置一些全局的变量

recipe文件用来将模版文件从模版路径输出到我们想要的路径

template文件就是配置我们新建Activity时的那个新建界面

.png的这张图就是我们的模版预览图片

root 就是我们Activity模版真正实现的地方

这里我贴一下我的MVP的模版代码，大家自行理解吧，应该不难的。

1.globals文件

<?xml version="1.0"?>
<globals>
    <global id="hasNoActionBar" type="boolean" value="false" />
    <global id="parentActivityClass" value="" />
    <global id="excludeMenu" type="boolean" value="true" />
    <global id="generateActivityTitle" type="boolean" value="false" />
    <global id="activityClass" value="${pageName}Activity" />
    <#include "../common/common_globals.xml.ftl" />
</globals>

2.recipe文件

<?xml version="1.0"?>
<#import "root://activities/common/kotlin_macros.ftl" as kt>
<recipe>
    <#include "../common/recipe_manifest.xml.ftl" />

<#else>
<instantiate from="root/src/app_package/MVPActivity.java.ftl"
