Android终止运行线程

Question

我使用此代码查找所有可运行的线程

我想终止这个帖子，但我的代码不能正常工作

我怎么样？

for (Thread t: Thread.getAllStackTraces().keySet()) {
    if (t.getState() == Thread.State.RUNNABLE) {
        t.stop();
        //Thread.interrupted();
    }
}

我会创建一个单独的类来实现Runnable并执行此操作：

public class GameLoopThread implements Runnable {

private GameView view;
private boolean running = false;
private SurfaceHolder surfaceHolder;

public GameLoopThread(GameView view) {
    this.view = view;
    surfaceHolder = view.getHolder();
}

@Override
public void run() {
    Canvas c;
    while (running) {
        c = null;
        try {
            c = this.surfaceHolder.lockCanvas();
            synchronized (surfaceHolder) {
                //draw your stuff
            }
        } finally {
            if (c != null) {
                surfaceHolder.unlockCanvasAndPost(c);
            }
        }
    }
}

public void setRunning(boolean run) { running = run; }
}

所以要创建线程，你会做

GameLoopThread gameLoopThread = new GameLoopThread(this);
gameLoopThread.setRunning(true);
Thread t = new Thread(gameLoopThread);

当你想要阻止它时：

gameLoopThread.setRunning(false);

基本上它是一个可以阻止它的自定义线程。
