一、模块以及依赖
1、模块分类
应用：apply plugin: 'com.android.application'
库：apply plugin: 'com.android.library
区别是，application是能直接运行的
2、依赖分类：
implementation：添加到编译路径，并将依赖打包到apk。依赖不传递
api：和之前的compile一样，添加到编译依赖，并将依赖打包到apk。依赖传递
compileOnly：只参加编译不打包到apk
runtimeOnly：不参加依赖，但是打包到依赖
annotationProcessor：检测源代码，找出Annotation，根据注解自动生成代码
二、ARouter
1、什么是ARouter
A framework for assisting in the renovation of Android componentization (帮助 Android App 进行组件化改造的路由框架)
https://github.com/alibaba/ARouter
2、ARouter的使用
1、新建工程ARouter Demo
2、新建module: library1
3、在library1中新建Activity： Library1Activity
4、在library1中新建layout：activity_library1
5、在library1的manifest中配置Library1Activity
6、在library1的gradle的android的defaultConfig中配置：
javaCompileOptions {
annotationProcessorOptions {
arguments = [ AROUTER_MODULE_NAME : project.getName() ]
}
}
7、在library1的gradle的android的dependencies中配置：
implementation 'com.alibaba:arouter-api:1.5.1'
annotationProcessor 'com.alibaba:arouter-compiler:1.5.1'
8、Library1Activity配置：
@Route(path = "/xianbing/Library1Activity")
9、新建Application：App
10、App的onCreate中添加：
ARouter.openLog();
ARouter.openDebug();
ARouter.init(this);
在manifest中配置好
11、回到主app，主app需要依赖library1
12、在MainActivity中添加点击事件
13、在gradle中同样配置
javaCompileOptions {
annotationProcessorOptions {
arguments = [ AROUTER_MODULE_NAME : project.getName() ]
}
}
以及：
implementation 'com.alibaba:arouter-api:1.5.1'
annotationProcessor 'com.alibaba:arouter-compiler:1.5.1'
14、在MainActivity中添加点击事件
findViewById(R.id.button).setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
ARouter.getInstance().build("/xianbing/Library1Activity").navigation();
}
});
15、新建SecondActivity，manifest中配置
16、给SecondActivity添加@Route(path="/xianbing/SecondActivity")
17、在主activiyt中添加新的btn以及事件
findViewById(R.id.btn_with_param).setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
ARouter.getInstance().build("/xianbing/SecondActivity").withString("name", "xianbing").navigation();
}
});
18、转场动画
fade_in.xml
<?xml version="1.0" encoding="utf-8"?><alpha xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="3000" />
fade_out.xml
<?xml version="1.0" encoding="utf-8"?><alpha xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="3000" />
ARouter.getInstance().build("/xianbing/SecondActivity").withTransition(R.anim.fade_in, R.anim.fade_out).withString("name", "xianbing").navigation(MainActivity.this);
19、Fragment
@Route(path="/xianbing/DemoFragment")
public class DemoFragment extends Fragment {
@Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_demo, container, false);
return view;
}
}
findViewById(R.id.find_fragment).setOnClickListener(new View.OnClickListener(){
@Override public void onClick(View v) {
Fragment fragment = (Fragment) ARouter.getInstance().build("/xianbing/DemoFragment").navigation();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.fragment_parent, fragment);
transaction.commit();
}
}
);}
20、autowired需要
ARouter.getInstance().inject(this);
21、模块依赖
implementation project(':library')
22、app初始化以及在manifest中配置
23、拦截器
@Interceptor( priority =1)
public class LoginInterceptor implements IInterceptor {
@Override
public void process(Postcard postcard,InterceptorCallback callback) {
Log.i("Simon","LoginInterceptor process");
if (isLogined()) {
callback.onContinue(postcard);
}
else {
if (postcard.getPath().equalsIgnoreCase("/xianbing/DemoActivity")) {
callback.onInterrupt(new RuntimeException(""));
}
else {
callback.onContinue(postcard);
}
}
}
@Override
public void init(Context context) {
}
public boolean isLogined() {
return true;
}
}
