我所理解的组件化即是将项目按业务逻辑拆分成若干个模块,每个模块以Android Studio 中的Module为载体,模块之间没有相互依赖关系,它们依赖于公共的基础模块,模块之间使用路由进行通信,单个模块可以在开发时作为一个Application独立运行调试,而在打包时则作为一个Android Libary被App模块依赖,能够实现动态切换.
方法论:
- 抽取公共基础模块,如Utils,自定义控件,网络请求,数据库等.
- 模块化,即将业务逻辑进行拆分.使用Module承载
- 配置Gradle脚本,能够动态切换library和Application
- 加入路由模块.实现模块间通信.
前两步略过,每个项目的业务逻辑都不一样
-
新建
config.gradle文件,置于项目根目录,如下ext { //定义切换开关 isModule = true //统一管理公共变量 android = [ compileSdk : 26, minSdk : 16, targetSdk : 26, versionCode : 1, versionName : "1.0", buildToolsVersion : '26.0.2', supportVersion : "26.1.0", constraintVersion : "1.0.2", butterknifeVersion : "8.8.1", glideVersion : '3.7.0', rx2FastAndroidNetworking: '1.0.1', retrofitVersion : '2.3.0', dagger2Version : '2.8', rxjava2Version : '2.0.6', rxandroidVersion : '2.0.1', gsonVersion : '2.8.0', timberVersion : '4.5.1', roomVersion : "1.0.0", recyclerAdapterHelper : '2.9.30', matisseVersion : "0.4.3" ] //配置模块的applicationId,因为当library转换成Application时需要一个id appId = [ app : "com.wenjian.myplayer", home : "com.wenjian.home", finder : "com.wenjian.finder", videoplay: "com.wenjian.videoplay", mine : "com.wenjian.mine" ] //统一管理依赖库 dependencies = [ "appcompat-v7" : "com.android.support:appcompat-v7:$android.supportVersion", "recyclerview-v7" : "com.android.support:recyclerview-v7:$android.supportVersion", "support-v4" : "com.android.support:support-v4:$android.supportVersion", "design" : "com.android.support:design:$android.supportVersion", "cardview-v7" : "com.android.support:cardview-v7:$android.supportVersion", "rxjava" : "io.reactivex.rxjava2:rxjava:$android.rxjava2Version", "rxandroid" : "io.reactivex.rxjava2:rxandroid:$android.rxandroidVersion", "retrofit" : "com.squareup.retrofit2:retrofit:$android.retrofitVersion", "adapter-rxjava2" : "com.squareup.retrofit2:adapter-rxjava2:$android.retrofitVersion", "converter-gson" : "com.squareup.retrofit2:converter-gson:$android.retrofitVersion", "butterknife" : "com.jakewharton:butterknife:$android.butterknifeVersion", "butterknife-compiler" : "com.jakewharton:butterknife-compiler:$android.butterknifeVersion", "gson" : "com.google.code.gson:gson:$android.gsonVersion", "glide" : "com.github.bumptech.glide:glide:$android.glideVersion", "BaseRecyclerViewAdapterHelper": "com.github.CymChad:BaseRecyclerViewAdapterHelper:$android.recyclerAdapterHelper", "logging-interceptor" : "com.squareup.okhttp3:logging-interceptor:3.8.1", "room-rxjava2" : "android.arch.persistence.room:rxjava2:1.0.0", "cardstack" : "com.daprlabs.aaron:cardstack:0.3.1-beta0", "MZBannerView" : "com.github.pinguo-zhouwei:MZBannerView:v2.0.0", "constraint-layout" : "com.android.support.constraint:constraint-layout:1.0.2", "circleimageview" : "de.hdodenhof:circleimageview:2.2.0", "room-runtime" : "android.arch.persistence.room:runtime:$android.roomVersion", "room-compiler" : "android.arch.persistence.room:compiler:$android.roomVersion", "timber" : "com.jakewharton.timber:timber:$android.timberVersion", "matisse" : "com.zhihu.android:matisse:$android.matisseVersion", "arouter-api" : "com.alibaba:arouter-api:1.3.1", "arouter-compiler" : "com.alibaba:arouter-compiler:1.1.4", ] } -
在根项目的
build.gradle文件中引入以上配置文件apply from: "config.gradle"
-
然后再module的
build.gradle添加如下配置配置开关
if (isModule) { apply plugin: 'com.android.library' apply plugin: 'com.jakewharton.butterknife' }else { apply plugin: 'com.android.application' }用来动态切换,
butterknife插件是用来生成R2文件的,以便能在module当中使用butterknife,但是这里有个问题,当处于集成模式时需要使用R2.id.xxx,而在独立开发时需要使用R.id.xxx,这个切换工作完全是体力活,所以一般组件化不推荐使用butterknife,还是老老实实findViewById吧(虽然写起来不够优雅).定义全局变量
def cfg = rootProject.ext.android def appId = rootProject.ext.appId def deps = rootProject.ext.dependencies
主要是为了之后书写更加优雅简洁
配置
ApplicationId,如果是单独运行模式if (!isModule) { applicationId appId.home }
**配置
java资源目录和AndroidManifest**sourceSets{ main{ //在组件模式下 使用不同的manifest文件 if(!isModule){ manifest.srcFile 'src/main/module/AndroidManifest.xml' java.srcDirs 'src/main/module/java','src/main/java' }else{ manifest.srcFile 'src/main/AndroidManifest.xml' } } }因为你想要单独运行必须要有启动页和配置了启动页的
AndroidManifest文件添加基础模块和路由模块的依赖
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' implementation deps["recyclerview-v7"] implementation deps["cardview-v7"] implementation deps["appcompat-v7"] implementation deps["rxjava"] implementation deps["BaseRecyclerViewAdapterHelper"] implementation deps["glide"] implementation deps["design"] implementation deps["butterknife"] annotationProcessor deps["butterknife-compiler"] implementation deps["MZBannerView"] implementation project(':base') implementation deps["arouter-api"] annotationProcessor deps["arouter-compiler"] }
到此为止,普通模块的gradle 配置完毕
-
添加App模块的gradle配置
if (isModule) { implementation project(':home') implementation project(':finder') implementation project(':mine') implementation project(':videoplay') }
其他的和普通模块类似,这里在集成模式下去依赖其他的业务模块
