wish help you to fix your issue Hmmm... I don't see anything wrong with the code you've posted. I wonder if the problem lies with your fragment_drink.xml file?
In any case, I put together a working example based on your data.
code :
package com.example.spinnerfragmenttest;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity 
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}
package com.example.spinnerfragmenttest;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class DrinkFragment extends Fragment
{
    private Spinner mSpDrinkItem;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    {
        View v = inflater.inflate(R.layout.fragment_drink, container, false);

        mSpDrinkItem = (Spinner)v.findViewById(R.id.sp_drink_list);

        ArrayAdapter<CharSequence> drinkAd = ArrayAdapter.createFromResource(getActivity(), R.array.drink_item, android.R.layout.simple_spinner_item);
        drinkAd.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        mSpDrinkItem.setAdapter(drinkAd);


        return v;
    }
}
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment android:name="com.example.spinnerfragmenttest.DrinkFragment"
              android:id="@+id/drink_fragment"
              android:layout_width="match_parent"
              android:layout_height="match_parent" />

</RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <Spinner android:id="@+id/sp_drink_list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"/>

</RelativeLayout>

        <item>檸檬汁</item> 
    </string-array>

</resources>

seems to work fine If you need the value of the selected item you can simply use .getSelectedItem() of the spinner. So:
code :
String posicaoSpinner = posicaoSpinner.getSelectedItem().toString();
