我想实现两个子线程之间互相通讯的功能

Question

private void Thread2() {
new Thread() {
@Override
public void run() {
super.run();
int i = 0;
Looper.prepare();
handlerOne = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
switch (msg.what) {
case MSG_JJ:
Log.e("m_tag", "收到了Thread3发来的消息:");
break;
}
}
};
for (int j = 0; j < 20; j++) {
i++;
}
if (i > 10) {
if (null != handlerOne) {
Log.e("m_tag", "Thread2" + Thread.currentThread());
handlerOne.sendEmptyMessage(MSG_HH);
}
}
Looper.loop();
}
}.start();
}

private void Thread3() {
    new Thread() {
        @Override
        public void run() {
            super.run();
            int i = 0;
            Looper.prepare();
            handlerTwo = new Handler() {
                @Override
                public void handleMessage(Message msg) {
                    super.handleMessage(msg);
                    switch (msg.what) {
                        case MSG_HH:
                            Log.e("m_tag", "收到了Thread2发来的消息:");
                            break;
                    }
                }
            };
            for (int j = 0; j < 50; j++) {
                i++;
            }
            if (i > 25) {
                if (null != handlerTwo) {
                    Log.e("m_tag", "Thread3" + Thread.currentThread());
                    handlerTwo.sendEmptyMessage(MSG_JJ);
                }
            }
            Looper.loop();
        }
    }.start();
}

    代码如上所示，log打印的：11-20 15:48:33.920 5190-5190/? E/m_tag: btn2

11-20 15:48:33.920 5190-5206/? E/m_tag: Thread2Thread[Thread-152,5,main]
11-20 15:48:33.920 5190-5208/? E/m_tag: Thread3Thread[Thread-153,5,main]

就是发不出去，或者是发出去了没接受到？？？
