吐司没有出现在Android 4.4奇巧

我有一个使用吐司的应用程序，我已经使用Android 4.3测试它在三星Galaxy II，它工作正常。

I have an application that uses Toast and I have tested it on a Samsung Galaxy II using Android 4.3 and it works fine.

我最近得到了运行Android 4.4奇巧是Nexus 5，当我尝试加载吐司它不会出现。

I have recently gotten a Nexus 5 running Android 4.4 KitKat and when I try to load the Toast it doesn't appear.

的面包被删除或者改变奇巧的语法？

Has Toast been removed or the syntax altered in KitKat?

这是code我使用，使并调用吐司：

This is the code I'm using to make and call the Toast:

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item)
{
    int itemId = item.getItemId();
    switch (itemId) {

    case R.id.action_settings:
        Log.e("TOAST","This was called");
        Toast.makeText(MainActivity.this, "This is my Toast message!",Toast.LENGTH_LONG).show();
        break;
    }
    return true;
}

我已经调试的code，并通过线这一部分线踩所以它肯定是被称为，但没有任何反应。

I have Debugged the code and stepped through this part line by line so it is definitely being called, but nothing happens.
