Question

我想在后台检查2个整数是否相同。当它们相同时，我希望线程停止，我想要调用我的一个函数。我怎么能这样做？

Answer 1

I am going to make an assumption here that you know how to setup and execute java threads in the background. In your runnable, when defining your run() function you can setup a while true loop which then compares the value of the two numbers and breaks the loop if they are equal. if they are not equal it sleeps for x milliseconds before it loops. After the loop you call the function you wanted to call if the values were equal. It should look like this:

public void run() {
    while(true){
        if(a == b){
            break;
        }
         Thread.sleep(200);
    }
    myfunction();
}

试试这个，

Runnable runnable = new Runnable() {
    @Override
    public void run() {
        if (!runnable.interrupted()) {
           if( varOne.equals(varTwo)) {
               yourFn();
            runnable.interrupted();
           } else {
               //Do nothing.
           }
        }
};
new Thread(runnable).start();

运行线程直到2整数是相同的
