1. 创建一个自定义的SpinnerAdapter
2. 在getView方法中设置TextView的背景颜色和文本颜色
3. 将自定义的SpinnerAdapter设置给Spinner

代码示例:

public class MySpinnerAdapter extends ArrayAdapter { private Context context; private String[] values;

public MySpinnerAdapter(Context context, int textViewResourceId,
        String[] values) {
    super(context, textViewResourceId, values);
    this.context = context;
    this.values = values;
}

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

    TextView textView = (TextView) super.getView(position, convertView, parent);
    textView.setTextColor(Color.WHITE);
    textView.setBackgroundColor(Color.BLACK);
    return textView;
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
    TextView textView = (TextView) super.getDropDownView(position, convertView, parent);
    textView.setTextColor(Color.WHITE);
    textView.setBackgroundColor(Color.BLACK);
    return textView;
}

}

// 在Activity中使用

Spinner spinner = (Spinner) findViewById(R.id.spinner); String[] values = {"item1", "item2", "item3"}; MySpinnerAdapter adapter = new MySpinnerAdapter(this, android.R.layout.simple_spinner_item, values); spinner.setAdapter(adapter);
