注册监听

A类中添加

1、定义监听接口
public interface OnPulseHandListener {
void onLeft(boolean isLeft);
}

2、监听调度类
public static class pulseHand{

    public static OnPulseHandListener onPulseHandListener = null;

    //设置监听器
    public void setPulseListener(OnPulseHandListener onPulseHandListener){
        this.onPulseHandListener = onPulseHandListener;
    }

    public static void doPulse(boolean isLeft) {
        if (onPulseHandListener != null) {
            onPulseHandListener.onLeft(isLeft);
        }
    }
}

B类中添加

3、期待执行的类中设置监听

public SenderThread.pulseHand pulseHand = new SenderThread.pulseHand();

pulseHand.setPulseListener(new SenderThread.OnPulseHandListener() {
public void onLeft(boolean isLeft) {
Log.i("OnPulseHandListener", "onLeft "+isLeft);
PulseHand(isLeft);
}
});

A类中调用监听执行
4、执行

pulseHand.doPulse(false);
