此问题暂时存在，并且不确定原因。
我正在从设备发送和接收数据。我想要做的就是将收到的消息与正在发送的对象上的变量集进行比较。
例如，我可以发送一个receiveValue为'Received 86 C0'的对象。
如果成功发送，我应该返回类似的内容：
IRDA1: Received 86 C0
我在日志名称'发送'下的对象上记录了返回值，然后我记录了名称'test'下返回的内容。
以下代码显示了我如何比较2个字符串：
public boolean checkReceived(DataCommand command) {
if (TextUtils.isEmpty(message)) {
return false;
}
if (message.contains(command.getCommandReturn())) {
return true;
}
else {
return false;
}
}
现在它似乎不起作用。它最终确实有效，但需要永远。例如，下面的日志显示程序最终正确比较字符串所花费的次数。

仅供参考：command.getCommandReturn()刚刚收到我正在讨论的变量。
感谢。
更新
我应该清除我的坏事。
Message是活动中类的开头声明的字符串变量。
public void onEventMainThread(TemplateMessageSystem event) {
Log.i("test", event.getMessage());
message = event.getMessage();
}
这是一个消息接收器，用于处理接收传入消息的不同线程。它确实正确地设置了消息变量以及它应该是什么。我不确定字符串比较的加载时间，但这种方法每1-2秒可能有2个字符串。
