您必须创建CustomSpinner,

为此,请尝试以下方式,它适用于我

第1步:创建自定义微调器类

    class CustomSpinnerAdapter extends CursorAdapter {
        LayoutInflater mInflater;

        private int cocktailname; 

        CustomSpinnerAdapter(Context context, Cursor cursor)
        {
            super(context, cursor);
            mInflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);  

          cocktailname = cursor.getColumnIndex(YourDatabase.CK_NAME);  

        }

        @Override
        public View newDropDownView (Context context, Cursor cursor, ViewGroup parent)
        {
             return mInflater.inflate(R.layout.dropdownspinnertext, parent, false); 
        }
        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent)
        {
            return mInflater.inflate(R.layout.spinnertext, parent, false); 
        }

       @Override
        public void bindView(View row, Context context, Cursor cursor)
        { 
                    //Setting the Value here
            TextView paymentname = (TextView) row.findViewById(R.id.text1);    
            paymentname.setTypeface(textFont);
            String cocktail = cursor.getString(cocktailname);
            paymentname.setText(cocktail); 

        }  

     }

第2步:调用此适配器

  CustomSpinnerAdapter custom_spinneradapter = new CustomSpinnerAdapter(this,youcursor);  
  spnListCocktails.setAdapter(custom_spinneradapter); 
  spnListCocktails.setOnItemSelectedListener(this);

xml for dropdownspinnertext

我正在使用Checked Dropdown Spinner

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1" 
style="?android:attr/spinnerDropDownItemStyle" 
android:singleLine="true" 
android:layout_width="fill_parent" 
android:layout_height="?android:attr/listPreferredItemHeight"
android:textColor="#FFFFFF"
android:textSize="18sp"
android:background="@drawable/background_image"
/>

对于spinnertext.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1" 
style="?android:attr/spinnerItemStyle"
android:singleLine="true" 
android:layout_width="fill_parent"
android:layout_height="wrap_content"  
android:textColor="#FFFFFF" 
android:gravity="center"
android:padding="4dip"
android:layout_marginLeft="10dip"
android:textSize="20sp"/>

希望有所帮助
