|
||
|
||
|
||
|
||
|
||
|
||
## 引入依赖环境
|
||
|
||
```java
|
||
implementation 'org.greenrobot:eventbus:3.2.0'
|
||
```
|
||
|
||
## 创建MessageEvent类
|
||
|
||
```java
|
||
public class MessageEvent {
|
||
|
||
public String message;
|
||
public MessageEvent(String message) {
|
||
this.message = message;
|
||
}
|
||
}
|
||
```
|
||
|
||
## 消息发送（POST）
|
||
|
||
```java
|
||
EventBus.getDefault().post(new MessageEvent(message));
|
||
```
|
||
|
||
## 消息接收（sub）
|
||
|
||
```java
|
||
@Subscribe(threadMode = ThreadMode.MAIN)
|
||
public void onMessageEvent(MessageEvent event) {
|
||
message= event.message;
|
||
Log.i("event-bus","messgae为"+message);
|
||
}
|
||
```
|
||
|
||
## 监听
|
||
|
||
```java
|
||
EventBus.getDefault().register(this);//在需要使用的地方注册
|
||
EventBus.getDefault().unregister(this);//不再使用后结束注册
|
||
```
