所以我在大约一年前设计了一个Android应用程序，现在在Android Studio中处理我学院的一些事情。但是，我从来没有完全完成＆＃34;它。它缺少的一件事是当我点击一个按钮它启动一个计时器并输出一个字符串。但是，如果我在该计时器启动之前按下另一个按钮，它将同时说两个按钮。在网上看，我还没找到我想要的东西，所以我想我会把它打开到Stackoverflow社区，也许你可以引导我朝着正确的方向前进。现在是代码。

非常感谢任何帮助。
public void BRC(View view) {

答案 0 :(得分：0)
在MainActivity函数中，声明一个变量来定义每个计数器的状态。在所有计数器的onTick（）中，使其检查变量
希望得到这个帮助。
