以锁的方式循环执行两个线程，当然也可以使用lock.newCondition实现线程的唤醒
Condition con1 = lock.newCondition();
final Lock lock = new ReentrantLock();
Thread thread = new Thread() {
@Override
public void run() {
while (true) {
int i = 0;
lock.lock();
Log.e("xmq", "aaaaaaaaaa");
lock.unlock();
try {
sleep(1000l);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
Thread thread1 = new Thread() {
@Override
public void run() {
while (true) {
int i = 0;
lock.lock();
Log.e("xmq", "bbbbbbbbbbbbb");
lock.unlock();
try {
sleep(1000l);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
thread.start();
thread1.start();
ReentrantReadWriteLock 读写锁
