主线程无法从线程获取通知

Question

我使用retrofit2从Web服务获取数据，但是当我从线程调用notify（）时，主线程无法获取它。挂起应用程序，我不知道为什么。我希望有一个人可以帮助我 。

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); synchronized (listRespones) { while (listRespones.size() < 2) { try { listRespones.wait(); } catch (InterruptedException e) { e.printStackTrace(); } } }

apiManager.getChannelListRespone(areaCode).enqueue(new Callback<CommonListRespone>() {

    @Override
    public void onResponse(Call<CommonListRespone> call, final Response<CommonListRespone> response) {
        Thread channel1 = new Thread(new Runnable() {
        @Override
        public void run() {
            synchronized (listRespones) {
                CommonListRespone commonChannel = response.body();

                listRespones.add(commonChannel);
                listRespones.notify();
            }
        }});
        channel1.start();


    }

    @Override
    public void onFailure(Call<CommonListRespone> call, Throwable t) {

    }});
