Android 使用 Rxjava2

1）引用

implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'
implementation 'io.reactivex.rxjava2:rxjava:2.1.5'

2）创建 方法

public final class RxBus {//this how to create our bus
    private static final BehaviorSubject<Object> behaviorSubject
            = BehaviorSubject.create();


    public static Disposable subscribe(@NonNull Consumer<Object> action) {
        return behaviorSubject.subscribe(action);
    }
    //use this method to send data
    public static void publish(@NonNull Object message) {
        behaviorSubject.onNext(message);
    }
}

3）发送消息

RxBus.publish( "发送消息");

4）接收消息

Disposable disposable = null;

@Override
protected void onCreate(Bundle savedInstanceState) {

disposable = RxBus.subscribe(new io.reactivex.functions.Consumer<Object>() {
    @Override
    public void accept(Object o) throws Exception {
        if (o instanceof String) {
            String data = (String) o;//接收消息
        }
    }
});

}

@Override
protected void onDestroy() {
    super.onDestroy();
    if (disposable != null) {
        disposable.dispose();
    }
}
