Question

每次我创建新的Thread时，它都被添加到主ThreadGroup中，甚至我将它仍然存在于主ThreadGroup中的线程中，从而导致内存泄漏。请帮忙

更新

public void surfaceDestroyed(SurfaceHolder holder) {
        Log.d("mThread", "Surface Destroyed Called");
        getHolder().removeCallback(this);
        boolean retry = true;
        _thread.setRunning(false);      
        while (retry) {
            try {
                Log.d("mThread", "b4 Interrupted");
                _thread.interrupt();
                Log.d("mThread", "b4 thread group Interrupted");
                _thread.getThreadGroup().interrupt();
                Log.d("mThread", "b4 join");
                _thread.join();
                retry = false;
            } catch (InterruptedException e) {
                Log.d("mThread", "Interrupted");
                Thread.currentThread().interrupt();
                _thread.getThreadGroup().list();                
                _thread = null;//======>here nulling thread
                break;
            }
        }
    }

Answer 1

问题不在于它被添加到线程组中。已终止的线程将始终（最终）从线程组中删除。

如果应用程序泄漏内存，则代码中存在错误。你正在咆哮错误的树。

Answer 2

如果线程存在于ThreadGroup中并且您需要将其删除，则可以使用ThreadGroup类的.remove()方法。它从ThreadGroup组中删除指定的线程。

语法：

void remove(Thread t);  
// t is thread to be removed from the ThreadGroup.
