android - 微调器下拉箭头

Question

我正在尝试获得像这样的自定义 Spinner:

但我只能得到这个:

如您所见，我遇到了几个问题。

1. 虽然我添加了自定义箭头，但我仍然看到原始箭头。
2. 我的自定义箭头显示在每一行。
3. 如何调整自定义箭头的尺寸和布局位置？
4. 如何生成带下划线的行？

这是我的代码:

onCreateView():

Spinner spinner = (Spinner) rootView.findViewById(R.id.spinner);
this.arraySpinner = new String[]{
    "Seleziona una data",
    "03 Agosto 2015",
    "13 Giugno 2015",
    "27 Novembre 2015",
    "30 Dicembre 2015",
};
ArrayAdapter<String> adapter = new ArrayAdapter<>(
        getActivity(),
        R.layout.row_spinner,
        R.id.weekofday,
        arraySpinner);

spinner.setAdapter(adapter);

res/layout/row_spinner.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="8dp">

    <TextView android:id="@+id/weekofday"
        android:singleLine="true"
        android:textSize="@dimen/textSize"
        style="@style/SpinnerDropdown"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <ImageView android:id="@+id/icon"
        android:paddingStart="8dp"
        android:paddingLeft="8dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/spinner_arrow"/>

</LinearLayout>

EDIT

我删除了 ImageView 并添加了第二个 Spinner 从 Resource 创建:

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
        getActivity(),
        R.array.date,
        R.layout.spinner_layout);
spinnerDate.setAdapter(adapter);

Spinner spinnerTime = (Spinner) rootView.findViewById(R.id.spinnerTime);
ArrayAdapter<CharSequence> adapterTime = ArrayAdapter.createFromResource(
        getActivity(),
        R.array.ore,
        R.layout.spinner_layout);
spinnerTime.setAdapter(adapterTime);

使用这种布局:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:padding="8dp"
    android:singleLine="true"
    android:layout_height="wrap_content" android:layout_width="match_parent"/>

我已将其添加到我的 style.xml 中:

<style name="AppTheme" parent="@style/_AppTheme"/>
<!-- Base application theme. -->
<style name="_AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:dropDownSpinnerStyle">@style/SpinnerTheme   </item>

    <item name="android:windowActionBarOverlay">false</item>
    <item name="colorPrimary">@color/ColorPrimary</item>
    <item name="colorPrimaryDark">@color/ColorPrimaryDark</item>
</style>

....
.... 
....

<!--Spinner styles 2-->
<style name="SpinnerTheme" parent="android:Widget.Spinner">
    <item name="android:background">@drawable/apptheme_spinner_background_holo_light</item>
    <item name="android:dropDownSelector">@drawable/apptheme_list_selector_holo_light</item>
</style>

<style name="SpinnerTheme.DropDown">
    <item name="android:spinnerMode">dropdown</item>
</style>

<!-- Changes the spinner drop down item radio button style -->
<style name="DropDownItemSpinnerTheme" parent="android:Widget.DropDownItem.Spinner">
    <item name="android:checkMark">@drawable/apptheme_btn_radio_holo_light</item>
</style>

<style name="ListViewSpinnerTheme" parent="android:Widget.ListView">
    <item name="android:listSelector">@drawable/apptheme_list_selector_holo_light</item>
</style>

<style name="ListViewSpinnerTheme.White" parent="android:Widget.ListView.White">
    <item name="android:listSelector">@drawable/apptheme_list_selector_holo_light</item>
</style>

<style name="SpinnerItemTheme"
    parent="android:TextAppearance.Widget.TextView.SpinnerItem">
    <item name="android:textColor">#000000</item>
</style>

但是没有结果!我仍然看到这个:

EDIT 2

我已将 style.xml 更改为:

这就是我得到的:

现在我没有替换下拉箭头图标，而是有了第二个图标，全息复选框(效果很好，当我选择一项时被选中)，但是，我如何才能只得到我想要的那个？ ？

您必须将 Imageview 移除到您的自定义布局 row_spinner.xml 中。以防万一，您不需要在自定义布局内创建箭头，因为如果您这样做，它会像发生在您身上的那样在每一行中创建。要执行您向我们展示的相同操作，您必须将 Spinner 样式更改为您的 styles.xml。

例如:

<resources>

    <style name="SpinnerTheme" parent="android:Widget.Spinner">
        <item name="android:background">@drawable/spinner_background_holo_light</item>
        <item name="android:dropDownSelector">@drawable/list_selector_holo_light</item>
    </style>

    <style name="SpinnerTheme.DropDown">
        <item name="android:spinnerMode">dropdown</item>
    </style>

    <!-- Changes the spinner drop down item radio button style -->
    <style name="DropDownItemSpinnerTheme" parent="android:Widget.DropDownItem.Spinner">
        <item name="android:checkMark">@drawable/btn_radio_holo_light</item>
    </style>

    <style name="ListViewSpinnerTheme" parent="android:Widget.ListView">
        <item name="android:listSelector">@drawable/list_selector_holo_light</item>
    </style>

    <style name="ListViewSpinnerTheme.White" parent="android:Widget.ListView.White">
        <item name="android:listSelector">@drawable/list_selector_holo_light</item>
    </style>

    <style name="SpinnerItemTheme" 
            parent="android:TextAppearance.Widget.TextView.SpinnerItem">
        <item name="android:textColor">#000000</item>
    </style>

</resources>

EDIT

选择器_spinner.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item>

        <layer-list>

            <item>
                <shape>
                    <gradient android:angle="90" android:endColor="#ffffff" android:startColor="#ffffff" android:type="linear" />

                    <stroke android:width="1dp" android:color="#504a4b" />

                    <corners android:radius="5dp" />

                    <padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
                </shape>
            </item>

            <item>

                <bitmap android:gravity="bottom|right" android:src="@android:drawable/arrow_up_float" />

            </item>

        </layer-list>

    </item>

</selector>

样式.xml:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
        <item name="android:spinnerStyle">@style/SpinnerTheme</item>
    </style>

    <style name="SpinnerTheme" parent="android:Widget.Spinner">
        <item name="android:background">@drawable/selector_spinner</item>
    </style>

</resources>

最后，微调器看起来像

以下代码放入details_fragment_three.xml

<Spinner
    android:id="@+id/spinnerDate"
    android:layout_marginLeft="-8dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/spinner_item_drawable"/>
