Question

我正在尝试访问一些SharedPreferences并在活动的Dialog方法内的mainUiThread上填充onCreate()：

这是我的onCreate()方法代码中的一些：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    new Handler(Looper.getMainLooper()).post(new Runnable() {

        @Override
        public void run() {
            // Access shared Prefs, then inflate a dialog using the 
            // LayoutInflater class
        }
    });
}

我为什么这样做？ 我注意到，我用来访问SharedPreferences然后膨胀Dialog的代码给主线程带来了沉重的负担，因此我将其放在Handler中。我开始在Crashlytics上找到它：

Fatal Exception: java.lang.IllegalStateException: The specified message queue synchronization  barrier token has not been posted or has already been removed.

   at android.os.HandlerThread.run(HandlerThread.java:61)

有什么主意吗？
