轮询超时/执行 案例
说明：这是在项目中用到的 实际操作请截取部分有关的片段【标记】
方便自己也方便大家
以后实现这个类中的接口即可

再比如 做一个一直轮询的任务 同样实现该接口 只是不做超时处理

task.startPolling();
eventBus.register(this);
}
public void stop() {//在必要时是要关闭的
if (task == null || !task.isStart()) {
return;
}
task.suspendPolling();
task = null;

}
@Override
public void onExecute() {

if (Util.stringIsEmpty(BJMGFCommon.getOfflineTime())) {

}
} else {

}
}
@Override
public void onTimeout() {
<span style="white-space:pre"> </span>//不作处理
}
public void onEventMainThread(BaseReceiveEvent revEvent) {
