在日常开发中，会经常使用反射调用隐藏api或者其他方法，此时需要一个非常方便就能指定位置的反射库，此反射库采用接口式的写法，可快速的复制源码上的方法，打上注解，反射代码则会自动生成，不用额外的编写反射代码。
allprojects { repositories { ... // 加入仓库 maven { url 'https://jitpack.io' } } }implementation 'com.github.CodingGay.BlackReflection:core:1.0.4' annotationProcessor 'com.github.CodingGay.BlackReflection:compiler:1.0.4'1. 如果你需要反射 android.app.ActivityThread 中的各种方法，参考：ActivityThread.java
@BClassName("android.app.ActivityThread") public interface ActivityThread { @BStaticMethod Object currentPackageName(); @BStaticMethod Object currentActivityThread(); @BMethod String getProcessName(); @BMethod void sendActivityResult(@BParamClass(IBinder.class) IBinder token, String id, int requestCode, int resultCode, Intent data); @BClassName("android.app.ActivityThread$H") interface H { @BStaticField int CREATE_SERVICE(); } } Object currentActivityThread = BRActivityThread.get().currentActivityThread(); String processName = BRActivityThread.get(currentActivityThread).getProcessName(); Log.d(TAG, "processName: " + processName); BRActivityThread是程序自动生成的类，生成规则是BR + ClassName
- BRActivityThread.get() 用于调用静态方法
- BRActivityThread.get(caller) 用于调用非静态方法
| 注解 | 注解方式 | 解释 |
|---|---|---|
| @BClass | Class | 指定需要反射的类 |
| @BClassName | Class | 指定需要反射的类 |
| @BStaticMethod | Method | 注明是静态方法 |
| @BMethod | Method | 注明是非静态方法 |
| @BStaticField | Method | 注明是静态变量 |
| @BField | Method | 注明是非静态变量 |
| @BParamClass | Parameter | 注明该参数的Class，用于反射时寻找方法 |
| @BParamClassName | Parameter | 注明该参数的Class，用于反射时寻找方法 |
详细用法请看Demo MainActivity.java
