java - Android 中的微调器颜色样式

Question

我正在制作如下图所示的 Spinner。它工作正常，如我所愿。但我想将 background 颜色更改为 #FFFFFF 并将 textColor 更改为 #000000。但是我得到了修改输出...

java代码:

Spinner staticSpinner = (Spinner)findViewById(R.id.static_spinner);
        ArrayAdapter<CharSequence> staticAdapter = ArrayAdapter.createFromResource(this,R.array.request_role,android.R.layout.simple_spinner_item);

        staticAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        // Apply the adapter to the spinner
        staticSpinner.setAdapter(staticAdapter);

xml代码:

<Spinner
         android:id="@+id/static_spinner"
         android:layout_width="150dp"
         android:layout_height="45dp"
         android:layout_marginLeft="30dp"
         style="@android:style/Widget.Holo.Light.DropDownItem"     ></Spinner>

simple_spinner_dropdown_item.xml

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="?android:attr/spinnerDropDownItemStyle"
    android:singleLine="true"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/dropdownListPreferredItemHeight"
    android:ellipsize="marquee"
    android:textColor="#000000"

  />

simple_spinner_item.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/text1"
    style="?android:attr/spinnerItemStyle"
    android:singleLine="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:textColor="#000000"
    android:textAlignment="inherit"/>

样式.xml

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

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat">

        <item name="colorPrimary">#0072BA</item>
        <item name="colorPrimaryDark">#004F80</item>

通过使用下面的代码我可以解决我的问题。

  <Spinner
                android:id="@+id/static_spinner2"
                android:layout_width="fill_parent"
                android:layout_height="32dp"
                android:layout_marginLeft="30dp"
                android:background="@drawable/apptheme_spinner_background_holo_light"
                android:popupBackground="#ffffff" />

Spinner_item.xml

<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="14sp"
    android:background="#FFFFFF"
    android:textColor="#000000" />

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:singleLine="true"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:ellipsize="marquee"
    android:textColor="#000000"/>

Java 代码:

Spinner staticSpinner = (Spinner)findViewById(R.id.static_spinner);
        ArrayAdapter<CharSequence> staticAdapter =
                ArrayAdapter.createFromResource(this,R.array.request_role,R.layout.spinner_item);

        staticAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);

        // Apply the adapter to the spinner
        staticSpinner.setAdapter(staticAdapter);
