关于android页面跳转我们一般使用自带intent进行跳转就像下面写的一样：
Intent intent = new Intent(mContext, MainActivity.class);
intent.putExtra("key","value");
startActivity(intent);
Intent intent = new Intent(mContext, MainActivity.class);
intent.putExtra("key","value");
startActivityForResult(intent, 1);
使用这种页面跳转的方式一般我会遇到下面集中问题：
- 多人开发，组件化开发，别人并不知道你的页面名字什么
- 隐士的intent跳转，清单文件配置会很混乱，配置过多的话也会重叠
- 跳转过程无法干预，进行其他的判断
- 代码繁琐（重点啊重点）
现在android有关路由使用的框架一般都是使用的阿里的ARouter，链接如下：
添加以下依赖：
defaultConfig {
......
javaCompileOptions {
annotationProcessorOptions {
arguments = [moduleName: project.getName()]
}
}
......
}
implementation 'com.alibaba:arouter-api:1.2.4'
annotationProcessor 'com.alibaba:arouter-compiler:1.1.2'
application进行配置：
if (isDebug) {
ARouter.openLog();
ARouter.openDebug();
}
ARouter.init(this);
配置工具类进行路由的统一配置：
String ACTIVITY = "/activity/";
String MAIN_2_ACTIVITY = ACTIVITY + "MAIN_2_ACTIVITY";
String MAIN_3_ACTIVITY = ACTIVITY + "MAIN_3_ACTIVITY";
/**
* 直接跳转
*/
ARouter.getInstance().build(Utils.MAIN_2_ACTIVITY).navigation();
/**
* 携带参数
*/
ARouter.getInstance().build(Utils.MAIN_3_ACTIVITY)
.withString("bookId", "123")
.withString("chapterId", "12")
.navigation();
/**
* 分组
*/
// 这个页面主动指定了Group名
ARouter.getInstance().build("/module/2", "m2").navigation();
/**

*/

ARouter.getInstance().build(uri).navigation();
/**
