这里有一个链接，可以帮助你改变旋转器的颜色:

点击这里

<Spinner
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/spinner"
    android:textSize="20sp"
    android:entries="@array/planets"/>

你需要用自定义的spinner_item.xml创建你自己的布局文件:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:textColor="#ff0000" />

如果要自定义下拉列表项，则需要创建一个新的布局文件。spinner_dropdown_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="?android:attr/spinnerDropDownItemStyle"
    android:maxLines="1"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:ellipsize="marquee"
    android:textColor="#aa66cc"/>

最后是旋转器声明中的另一个变化:

ArrayAdapter adapter = ArrayAdapter.createFromResource(this,
R.array.planets_array, R.layout.spinner_item);

adapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
spinner.setAdapter(adapter);

就是这样。

我是这样做的。我已经使用getDropDownView()和getView()方法。

对于打开的微调器使用getDropDownView()。

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
  View view = convertView;
  if (view == null) {
    LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = vi.inflate(R.layout.context_row_icon, null);
  }
  TextView mTitle = (TextView) view.findViewById(R.id.context_label);
  ImageView flag = (ImageView) view.findViewById(R.id.context_icon);                

  mTitle.setText(values[position].getLabel(activity));

  if (!((LabelItem) getItem(position)).isEnabled()) {
    mTitle.setTextColor(activity.getResources().getColor(R.color.context_item_disabled));
  } else {
    mTitle.setTextColor(activity.getResources().getColor(R.color.context_item));
  }
  return view;
}

关闭的微调器使用getView()。

@Override
public View getView(int position, View convertView, ViewGroup parent) {
  View view = convertView;
  if (view == null) {
    LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = vi.inflate(R.layout.context_row_icon, null);
  }
  TextView mTitle = (TextView) view.findViewById(R.id.context_label);
  ImageView flag = (ImageView) view.findViewById(R.id.context_icon);

  mTitle.setText(values[position].getLabel(activity));
  mTitle.setTextColor(activity.getResources().getColor(R.color.context_item_disabled));

  return view;
}

你可以有这种类型的转轮适配器，完全定制:

 ArrayAdapter<String> genderAdapter = new ArrayAdapter<String>(getActivity(), R.layout.spinner_text, genderList) {

        public View getView(int position, View convertView, ViewGroup parent) {
            View v = super.getView(position, convertView, parent);
            ((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
            ((TextView) v).setTextColor(Color.parseColor("#676767"));
            ((TextView) v).setTypeface(vrFont);
            return v;
        }

        public View getDropDownView(int position, View convertView, ViewGroup parent) {
            View v = super.getDropDownView(position, convertView, parent);
            ((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
            ((TextView) v).setTypeface(vrFont);
            ((TextView) v).setTextColor(Color.parseColor("#676767"));

            if (position == 0) {
                ((TextView) v).setTextColor(Color.parseColor("#979797"));
            }

            return v;
        }

而出来。spinner_text是:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1"
style="?android:attr/spinnerItemStyle"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:gravity="center_vertical|left"
android:ellipsize="marquee"
android:maxLines="1"
android:textColor="@color/whiteThree" />

为了防止滞后，你不仅需要在onItemSelected监听器中设置文本属性，还需要在Activity的onCreate方法中设置文本属性(但这有点棘手)。

具体来说，你需要在设置适配器后把这个放在onCreate中:

spinner.setSelection(0, true);
View v = spinner.getSelectedView();
((TextView)v).setTextColor(backgroundColor);

然后把这个放到onItemSelected中:

((TextView) view).setTextColor(backgroundColor);

下面是一个完整的例子:

@Override  
protected void onCreate(Bundle savedInstanceState)
{  
    Spinner spinner = (Spinner) findViewById(R.id.spinner); 

    //Set the choices on the spinner by setting the adapter.  
    spinner.setAdapter(new SpinnerAdapter(toolbar.getContext(), new String[]{"Overview", "Story", "Specifications", "Poll", "Video"}, accentColor, backgroundColor));

    //Set the text color of the Spinner's selected view (not a drop down list view) 
    spinner.setSelection(0, true);
    View v = spinner.getSelectedView();
    ((TextView)v).setTextColor(backgroundColor);

    //Set the listener for when each option is clicked.  
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
    {  

        @Override  
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
        {  
           //Change the selected item's text color  
           ((TextView) view).setTextColor(backgroundColor);
        }  

        @Override  
        public void onNothingSelected(AdapterView<?> parent)
        {  
        }  
    });  

}  

要了解更多细节，请参见我的问题。

为旋转器项创建自定义XML文件。

spinner_item.xml:

将自定义的颜色和大小设置为该文件中的文本。

<?xml version="1.0" encoding="utf-8"?>

<TextView  
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:gravity="left"  
    android:textColor="#FF0000"         
    android:padding="5dip"
    />

现在使用这个文件来显示你的旋转项，比如:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinner_item,list);

您不需要设置下拉资源。它将只使用spinner_item.xml来在spinner中显示您的项目。

简单而干脆……

private OnItemSelectedListener OnCatSpinnerCL = new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

       ((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);
       ((TextView) parent.getChildAt(0)).setTextSize(5);

    }

    public void onNothingSelected(AdapterView<?> parent) {

    }
};
