具有非活动类/线程的Android Toast队列

Question

我正在研究线程队列。我的目标是确保同一时间不超过一个烤面包重叠。示例在onCreate，onStart，onResume中烤面包。

首先，我为带有烤面包队列和活动上下文的烤面包助手创建一个类。该队列执行线程，直到队列中没有任何项目，但是此代码不起作用，我看不到任何吐司

班级

public class ToastCreater {
    private static List<ToastSettings> _toastQueue = new ArrayList<>();
    public static void CreateToast(final ToastSettings toastSettings) {
        _toastQueue.add(toastSettings);
        if (_toastQueue.size() != 0) {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        for (ToastSettings item : _toastQueue) {
                            Toast.makeText(item.getContext(), item.getMessage(), item.isLong() ? Toast.LENGTH_LONG : Toast.LENGTH_SHORT);
                            if (item.isLong()) Thread.sleep(4000);//Long 3500ms Short 2000ms
                            else Thread.sleep(3000);
                            _toastQueue.remove(item);
                        }
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            });

        }
    }

    public static class ToastSettings {
        private String Message;
        private boolean IsLong;
        private Context Context;

        public android.content.Context getContext() {
            return Context;
        }

        public ToastSettings setContext(android.content.Context context) {
            Context = context;
            return this;
        }

        public String getMessage() {
            return Message;
        }

        public ToastSettings setMessage(String message) {
            Message = message;
            return this;
        }

        public boolean isLong() {
            return IsLong;
        }

        public ToastSettings setLong(boolean aLong) {
            IsLong = aLong;
            return this;
        }

    }

}

用法：

ToastCreater.CreateToast(
                new ToastCreater.ToastSettings()
                       .setContext(this.getBaseContext())
                        .setMessage("onCreate")
                        .setLong(true));
