有人想要Android面向切面编程,今天他来了!轻松完成各种骚操作,登录状态拦截,日志拦截,权限拦截,轻松搞定!
1.project.gradle
buildscript {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'org.aspectj:aspectjtools:1.9.6'
classpath 'com.github.TanZhiL.OkAspectj:okaspectj-plugin:+'
}
}
2.app.gradle 添加(注意每个需要生成切面的文件的组件都需要添加annotationProcessor)
apply plugin: 'com.xtc.thomas.okaspectj'
dependencies {
implementation 'org.aspectj:aspectjrt:1.9.6'
implementation 'com.github.TanZhiL.OkAspectj:okaspectj:+'
annotationProcessor 'com.github.TanZhiL.OkAspectj:okaspectj-compiler:+'
}
@OkAspectj
@Target(ElementType.METHOD)
public @interface NeedLogin {
int value()default 0;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
test();
test1();
}
@NeedLogin(2)
private void test() {
}
@TestAnnotaion
private void test1() {
}
}
3.在Application设置全局切面拦截处理
public class App extends Application {
private static final String TAG = "App";
@Override
public void onCreate() {
super.onCreate();
OkAspectjHelper.init(new PointHandler() {
@Override
public void onHandlePoint(Class clazz, ProceedingJoinPoint joinPoint) {
Log.d(TAG, "handlePoint() called with: clazz = [" + clazz + "]");
if(clazz==NeedLogin.class){
MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
NeedLogin annotation = methodSignature.getMethod().getAnnotation(NeedLogin.class);
Log.d(TAG, "handlePoint() called with: joinPoint = [" + annotation.value() + "]");
try {
joinPoint.proceed();
} catch (Throwable throwable) {
throwable.printStackTrace();
}
}
}
});
}
}
4.配置完成,可以在onHandlePoint(Class clazz, ProceedingJoinPoint joinPoint)中自由发挥你的骚操作了! 5.也可自己编写切面文件,然后通过调用OkAspectjHelper.notifyHandler(Class clazz,ProceedingJoinPoint joinPoint),发送切点信息进行统一处理.
6.拦截系统方法请参考以下案例.
1.点击事件
@OkAspectj("execution(* android.view.View.OnClickListener.onClick(..))")
@Target(ElementType.METHOD)
public @interface TestClick {
}
2.生命周期
@OkAspectj("execution(* android.app.Activity.on**(..))")
@Target(ElementType.METHOD)
public @interface TestLifeCycle {
}
