Question

我有一些关于设置微调器

的问题

我需要更改微调器的drawable（选定视图）当用户打开下拉列表时（我尝试了几个选择器具有不同的状态，但没有正常工作）
我无法更改下拉列表中项目的文字颜色（我可以更改颜色，但我需要不同颜色的选定值）你可以看到更多以下链接中的详细信息。
我不能从下拉列表中删除分隔符。

我不想使用带按钮和列表的自定义布局来模拟微调器的功能（但如果没有解决方案，我会这样做）。

style.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">

<style name="AppBaseTheme" parent="@android:style/Theme.Black.NoTitleBar.Fullscreen">
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/white</item>
    <item name="android:colorBackground">@android:color/white</item>
    <item name="android:dropDownSpinnerStyle">@style/SpinnerTheme</item>
</style>

<style name="SpinnerAppTheme" parent="android:Widget.Holo.Light.Spinner">
    <item name="android:background">@drawable/spinner_background_holo_light</item>
    <item name="android:dropDownSelector">@drawable/list_selector_holo_light</item>
    <item name="android:dropDownListViewStyle">@style/mySpinnerStyle</item>
</style>

<style name="mySpinnerStyle" parent="android:Widget.ListView.DropDown">
     <item name="android:divider">@null</item>
    <item name="android:dividerHeight">0px</item>
</style>

<style name="Theme_Dialog_Translucent" parent="android:Theme.Dialog">
    <item name="android:windowBackground">@null</item>
    <item name="android:background">@android:color/white</item>
    <item name="android:windowTitleStyle">@style/dialog_title_style</item>
</style>

<style name="Theme_Dialog_Measurment_Data_Dialog" parent="android:Theme.Dialog">
    <item name="android:windowBackground">@null</item>
    <item name="android:background">@color/general_background_color</item>
    <item name="android:windowTitleStyle">@style/dialog_title_style</item>
</style>

<style name="dialog_title_style" parent="android:Widget.TextView">
    <item name="android:textColor">@android:color/black</item>
</style>

 <Spinner
     android:id="@+id/res_spinner"
     android:layout_width="0dp"
     android:layout_height="30dp"
     android:layout_weight="60"
     android:background="@drawable/ref_spinner_selector"
     android:dropDownVerticalOffset="1dp"
     android:dropDownWidth="60dp"
     android:gravity="center"
     android:popupBackground="@null"
     android:spinnerMode="dropdown"/>

how the spinner needs to be look like

how the spinner looks like now

更新：如果有人有问题来定制微调器

我设法使用ListPopupWindow解决所有问题

private void initPopup()
{
    _lp = new ListPopupWindow(getActivity());
    _lp.setAnchorView(_resTitle);

    ColorDrawable cd = new ColorDrawable(getResources().getColor(android.R.color.transparent));

    _lp.setBackgroundDrawable(cd);
    _lp.setOnDismissListener(new OnDismissListener()
    {

        @Override
        public void onDismiss()
        {
            _resTitle.setSelected(false);
        }
    });
    _listPopupAdapter = new DataSetListAdapter(getActivity(), _resData);
    _lp.setAdapter(_listPopupAdapter);
}

的onclick

案例R.id.res_title：

            if (!_lp.isShowing())
            {
                _resTitle.setSelected(true);
                _lp.setOnItemClickListener(this);
                _lp.show();
                _lp.getListView().setDivider(null);
                _lp.getListView().setDividerHeight(0);
            }
            else
            {
                _resTitle.setSelected(false);
                _lp.dismiss();
            }
            break;

Android不允许自定义微调器UI.So 如果你想修改你的微调器UI，那么使用android弹出视图，你可以在这里放置你的风格UI，效果如下拉菜单示例

  spinner=(EditText)findViewById(R.id.txt_Spinner);


    spinner.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            p = new Point();
            p.x = location[0]+(v.getHeight());
            p.y = location[1]+v.getHeight();

            if (p != null)
                showPopup(statusActivity.this, p);

            System.out.println("show popup");
        }
    });




// The method that displays the popup.
private void showPopup(final Activity context, Point p) {
    int popupWidth = 300;
    int popupHeight = 500;

    // Inflate the popup_layout.xml
    LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popup);
    LayoutInflater layoutInflater = (LayoutInflater) context
    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View layout = layoutInflater.inflate(R.layout.popup_layout, viewGroup);

    // Creating the PopupWindow
    popup = new PopupWindow(context);
    popup.setContentView(layout);
    popup.setWidth(popupWidth);
    popup.setHeight(popupHeight);
    popup.setFocusable(true);

    // Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
    int OFFSET_X = 00;
    int OFFSET_Y = 00;

    // Clear the default translucent background
    popup.setBackgroundDrawable(new BitmapDrawable());

    // Displaying the popup at the specified location, + offsets.
    popup.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);
    ((TextView)layout.findViewById(R.id.textView2)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView3)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView4)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView5)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView6)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView7)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView8)).setClickable(true);
    ((TextView)layout.findViewById(R.id.textView9)).setClickable(true);

}
