如何更改微調項目中文本的背景顏色？

Question

如何更改微調器選項的背景顏色？我不想改變整個背景顏色，所以我不能在佈局中定義它。

String[] strings = {"Somelist", "SOmelist"}; 

Spinner spinner = (Spinner) findViewById(R.id.spinner1); 
     spinner.setAdapter(new MyAdapter(this, R.layout.row, strings)); 

....  

public class MyAdapter extends ArrayAdapter<String> { 

      public MyAdapter(Context context, int textViewResourceId, 
        String[] objects) { 

       super(context, textViewResourceId, objects); 

      } 

      @Override 
      public View getDropDownView(int position, View convertView, 
        ViewGroup parent) { 

       return getCustomView(position, convertView, parent); 

      } 

      @Override 
      public View getView(int position, View convertView, ViewGroup parent) { 

       return getCustomView(position, convertView, parent); 

      } 

      public View getCustomView(int position, View convertView, 
        ViewGroup parent) { 

       LayoutInflater inflater = getLayoutInflater(); 

       View row = inflater.inflate(R.layout.row, parent, false); 

       TextView label = (TextView) row.findViewById(R.id.company); 

       label.setText(strings[position]); 

       TextView sub = (TextView) row.findViewById(R.id.sub); 

       sub.setText(subs[position]); 

///You can have different combinations on which items in the list you want to change background, text or anything else 

       if (position % 2 == 0) { 
        label.setTextColor(Color.BLUE); 
        row.setBackgroundColor(Color.RED); 
       } 

       return row; 

      } 

     } 

佈局：

<TextView 
    android:id="@+id/company" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_marginLeft="5dip" 
    android:layout_marginTop="2dip" 
    android:padding="3dip" 
    android:text="CoderzHeaven" 
    android:textStyle="bold" /> 

<TextView 
    android:id="@+id/sub" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/company" 
    android:layout_marginLeft="5dip" 
    android:padding="2dip" 
    android:text="Heaven of all working codes" />
