线程中的synchronized使用
?
private static class ListenerHandlerThread implements Runnable {
?
private Looper looper;
?
private byte[] listenerKey = new byte[0];
?
public ListenerHandlerThread() {
new Thread(this).start();
synchronized (listenerKey) {
while (looper == null) { ?//注意while必须放synronized里面，不然会出错
try {
listenerKey.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
?
public Looper getLooper() {
return looper;
}
?
@Override
public void run() {
Looper.prepare();
looper = Looper.myLooper();
synchronized (listenerKey) {
listenerKey.notifyAll();
}
Looper.loop();
}

}
