AndroidStudio 4.X+ 编写自定义模板

写在前面此文仅为记录AndroidStudio fox 编写自定义模板，网上关于此类文章少之又少，踩了不少坑，遂写文记录希望能帮到有需要的人。

AndroidStudio 自定义模板主要区分在AS 4.0版本
- AndroidStudio 4.0版本之前，编写自定义模板使用Freemarket进行编写，并存放在 AS 的plugin - template 文件夹下即可。可参考鸿洋文章 AndroidStudio自定义模板进行学习。
- AndroidStudio 4.0版本之后，AS 没有了 plugin 文件夹，但提供了新的方式：使用Kotlin 编写 template，以jar包形式使用。
此文编写模板是依附于自己项目 QuickAndroid 进行编写,开发工具：AndroidStudio Fox 2020.3.1 Patch 3 Build

开始

Use this template

我们需要在官方的template模板上进行编写，官方模板地址为:intellij-platform-plugin-template,打开模板仓库后，点击Use this template 会提示你 Create a new repository from intellij-platform-plugin-template 类似fork，创建好仓库后，git clone 到本地，并使用AS 打开

添加依赖

添加wizard-template.jar
- 项目根目录下创建lib文件夹
- 添加AndroidStudio目录下的wizard-template.jar,具体路径为:/Applications/Android Studio.app/Contents/plugins/android/lib/
- 打开项目build.gradle.kts文件，添加代码如下：

dependencies {
    compileOnly(files("lib/wizard-template.jar"))
}

添加plugins
- 打开项目build.gradle.kts文件，在plugins下添加detekt 和 ktlint插件
- 添加detekt依赖代码如下：

    plugins {
    ...
    // detekt linter - read more: https://detekt.github.io/detekt/gradle.html
    id("io.gitlab.arturbosch.detekt") version "1.16.0"
    // ktlint linter - read more: https://github.com/JLLeitschuh/ktlint-gradle
    id("org.jlleitschuh.gradle.ktlint") version "10.0.0"
}


dependencies {
    detektPlugins("io.gitlab.arturbosch.detekt:detekt-formatting:1.18.1")
}

添加过依赖后build.gradle.kts 下plugins 和dependencies代码：

plugins {
    // Java support
    id("java")
    // Kotlin support
    id("org.jetbrains.kotlin.jvm") version "1.6.0"
    // Gradle Changelog Plugin
    id("org.jetbrains.changelog") version "1.3.1"
    // Gradle Qodana Plugin
    id("org.jetbrains.qodana") version "0.1.13"
    // Gradle IntelliJ Plugin
    id("org.jetbrains.intellij") version "1.3.0"
    // detekt linter - read more: https://detekt.github.io/detekt/gradle.html
    id("io.gitlab.arturbosch.detekt") version "1.16.0"
    // ktlint linter - read more: https://github.com/JLLeitschuh/ktlint-gradle
    id("org.jlleitschuh.gradle.ktlint") version "10.0.0"
}


dependencies {
    detektPlugins("io.gitlab.arturbosch.detekt:detekt-formatting:1.18.1")
    compileOnly(files("lib/wizard-template.jar"))
}

修改gradle.properties

修改gradle.properties文件下相关配置具体意义查看Gradle properties
- pluginGroup
- pluginName
- pluginVersion : 编译后生成jar版本号就是这里控制的
- pluginSinceBuild
- pluginUntilBuild
- pluginVerifierIdeVersions
- platformType
- platformVersion
- platformPlugins
此处需注意的是 pluginSinceBuild pluginUntilBuild pluginVerifierIdeVersions
- pluginSinceBuild:表示插件适配的最低版本
- pluginUntilBuild:表示插件适配的最高版本
- pluginVerifierIdeVersions: 4.X版本AS 使用模板会有此字段，Fox版本没有，文档也没有显示，个人还是添加上了
- 关于最低最高版本就是AS 版本信息中build 信息，本人使用的是AndroidStudio Fox 2020.3.1 Patch 3 Build，build 信息为203.xxxx

gradle.properties文件内容如下：

# IntelliJ Platform Artifacts Repositories
# -> https://plugins.jetbrains.com/docs/intellij/intellij-artifacts.html

pluginGroup = me.jiayang
pluginName = tin-mvvm
# SemVer format -> https://semver.org
pluginVersion = 1.0.72

# See https://plugins.jetbrains.com/docs/intellij/build-number-ranges.html
# for insight into build numbers and IntelliJ Platform versions.
pluginSinceBuild = 201
pluginUntilBuild = 213.*
pluginVerifierIdeVersions = 2020.2.4, 2020.3.4, 2021.1
# IntelliJ Platform Properties -> https://github.com/JetBrains/gradle-intellij-plugin#intellij-platform-properties
platformType = IC
platformVersion = 2020.2.4

# Plugin Dependencies -> https://plugins.jetbrains.com/docs/intellij/plugin-dependencies.html
# Example: platformPlugins = com.intellij.java, com.jetbrains.php:203.4449.22
platformPlugins = java, com.intellij.java, org.jetbrains.android, android, org.jetbrains.kotlin

# Java language level used to compile sources and to generate the files for - Java 11 is required since 2020.3
javaVersion = 11

# Gradle Releases -> https://github.com/gradle/gradle/releases
gradleVersion = 7.3

# Opt-out flag for bundling Kotlin standard library.
# See https://plugins.jetbrains.com/docs/intellij/kotlin.html#kotlin-standard-library for details.
# suppress inspection "UnusedProperty"
kotlin.stdlib.default.dependency = false

修改包名以及创建Template生成类

修改项目包名
- AS 打开项目后，可以看到src - kotlin - 包名 - listeners services ...
- 修改包名，个人修改结果如下
- 具体为src - kotlin - 包名 me.jiayang - 两个文件夹，一个存放项目原本文件 template，一个存放自定义模板代码 tinmvvm

修改MyProjectManagerListener

internal class MyProjectManagerListener : ProjectManagerListener {

    override fun projectOpened(project: Project) {
        projectInstance = project
        project.getService(MyProjectService::class.java)
    }

    override fun projectClosing(project: Project) {
        projectInstance = null
        super.projectClosing(project)
    }

    companion object {
        var projectInstance: Project? = null
    }
}

创建Template入口生成类 SamplePluginTemplateProviderImpl
- tinmvvm文件夹下创建 SamplePluginTemplateProviderImpl类
- WizardTemplateProvider的是 lib 下 wizard-template.jar的抽象类
- mvvmActivityTemplate为具体生成Template对象

class SamplePluginTemplateProviderImpl: WizardTemplateProvider() {
    override fun getTemplates(): List<Template> = listOf(
        mvvmActivityTemplate
    )
}

修改plugin.xml
- 创建好SamplePluginTemplateProviderImpl类后，打开resources-META-INF-plugin.xml文件
- 修改id
- 修改name：此处名字是AS plugin安装后显示的名字
- 修改vendor:此处为AS plugin 安装后显示的作者名字
- 添加三个 depends
- 添加extensions 指定defaultExtensionNs 为 com.android.tools.idea.wizard.template，wizardTemplateProvider 为创建的SamplePluginTemplateProviderImpl类
- 此处注意，一定要写全路径，包名一定一定一定要写上,4.X版本编写的时候网上的文章都没有写，个人不清楚4.X版本是否真的不用写全路径

<idea-plugin>
    <id>me.jiayang.tinmvvm</id>
    <name>TinMVVM</name>
    <vendor>jiayang</vendor>

    <depends>org.jetbrains.android</depends>
    <depends>org.jetbrains.kotlin</depends>
    <depends>com.intellij.modules.java</depends>
    <depends>com.intellij.modules.platform</depends>

    <extensions defaultExtensionNs="com.intellij">
        <applicationService serviceImplementation="me.jiayang.template.services.MyApplicationService"/>
        <projectService serviceImplementation="me.jiayang.template.services.MyProjectService"/>
    </extensions>

    <applicationListeners>
        <listener class="me.jiayang.template.listeners.MyProjectManagerListener"
                  topic="com.intellij.openapi.project.ProjectManagerListener"/>
    </applicationListeners>
    <extensions defaultExtensionNs="com.android.tools.idea.wizard.template">
        <wizardTemplateProvider implementation="me.jiayang.tinmvvm.SamplePluginTemplateProviderImpl" />
    </extensions>
</idea-plugin>

创建Teplater具体对象mvvmActivityTemplate,本人原本想着写两个Template对象，后将Fragment Activity 都写在了一个下面，别纠结创建的文件夹名字已经文件名为activity
- tinmvvm 文件夹下创建了activity文件夹，并在其下创建名为mvvmActivityTemplate的kt文件
- 此处个人说明一下个人踩的坑以及对字段含义
  - revision ：低版本的时候用于说明版本，此次fox编译的时候 revision会报错，遂注释
  - name : 编译好Jar包使用时，显示的模板名字
  - description : 使用模板时，顶部简介
  - minApi : 低版本4.0以下编写的时候使用的min_api minBuildApi，用于说明编译版本，此次fox编写时，minBuildApi会报错，遂也改minApi ,MIN_API为lib 下 wizard-template.jar中字段
  - category : 定义为other
  - formFactor : 定义为 mobile
  - screens : 低版本编写的时候没有，此处具体本人也不太懂
  - 接下来就是模板上要显示内容了
  - 具体分为 stringParameter booleanParameter enumParameter
  - 说一些和低版本不同的地方：低版本有id type字段，此次发现没有了id type字段 ,type 个人觉得在你创建的时候已经指定了具体类型的Template
  - name：界面上的类似label的提示语,constraints：填写值的约束,suggest：建议值，比如填写ActivityName的时候，会给出一个布局文件的建议值,default:默认值,help:底部显示的提示语
  - 低版本 help 会在底部显示提示语，高版本会在鼠标放置字段上停滞一段时间后显示。
  - 编写template 必须给default 值，不然安装jar后会连入口都没有，包括官方的模板都没有！！！这里坑了自己两天，后扒AS启动日志才发现报错
  - widgets:将编写的Template对象放入。
  - recipe :设置具体替换对象。此处在activity文件夹下创建mvvmActivityRecipe的kt文件，将需要的值通过参数传入
  - mvvmActivityRecipe下根据类型写了创建act viewmodel repository 等，这些看代码即可，具体act viewmodel repository 看代码即可，这里简单说明一下就是创建方法，然后返回值为 string内容，内容写基础内容即可，放一个activity的内容吧，具体根据自己项目替换即可
- 编写template 必须给default 值错误日志图、文件代码内容如下:


val mvvmActivityTemplate
    get() = template {
//        revision = 1
        name = "Quick Template"

编译

编写好后点击 Gradle - Task - Build - jar，编译好后会在项目根目录-build-libs文件夹下生成jar包，名字为项目名-版本号.jar

可能你的Gradle 页面是这样的:

点击Task list not built..

去掉Gradle 下第一个 Do not build Gradle task list ..的勾选

拿着编译好的jar包，打开AS Settings/Preferences > Plugins > ⚙️ > Install plugin from disk... > RESTART IDE

点击app 或者包名 右键使用模板

最后

编写匆忙恐有疏漏如有不足尽情谅解
