java.lang.UnsupportedOperationException：インデックス13の属性を解決できませんでした：TypedValue {t = 0x2/d = 0x7f010046 a = -1}

Question

異なる色合いのためにandroid attrs.xmlファイルに属性を追加しました。 styles.xmlファイルでは、これらの属性の色を指定しているため、スタイルごとに異なります。

Attrs.xml：

<attr name="lightBackground" format="color" /> 
<attr name="normalBackground" format="color" /> 

のstyles.xml：

<style name="AppThemeNight" parent="Theme.AppCompat.Light.NoActionBar"> 
    <item name="colorPrimary">@color/colorPrimaryNight</item> 
    <item name="colorPrimaryDark">@color/colorPrimaryDarkNight</item> 
    <item name="colorAccent">@color/colorAccentNight</item> 

    <item name="drawerArrowStyle">@style/DrawerIcon</item> 
    <item name="lightBackground">@color/colorPrimaryLightNight</item> 
    <item name="normalBackground">@color/colorPrimaryNight</item> 
</style> 

は、カスタムスピナーレイアウトを膨らま：spinner_layout_adapter.xml：しかし

<?xml version="1.0" encoding="utf-8"?> 
<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/spinnerLayoutAdapter_tv_spinnerText" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:padding="15dp" 
     android:text="TextView" 
     android:textColor="@android:color/white" 
     android:background="?attr/normalBackground" 
     android:textSize="16sp"/>

属性を以下のような通常の色で変更すると機能します。属性？attr/normalBackgroundは機能していないようです。

android:background="@color/colorPrimary" 

誰かが私が間違っていた考えを持っていますか？

Answer 1

「AppThemeNight」を使用する場所はどこですか？あなたのコードで小さなプロジェクトをセットアップし、 "AppThemeNight"がマニフェストで使用され、すべてが期待どおりに機能することを定義しました。私はマニフェストで「AppThemeNight」への参照を削除するとアプリが次のエラーでアウトエラーが発生した：

Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 13: TypedValue{t=0x2/d=0x7f0200c9 a=-1}

私はあなたが見ていることを考えるものであるので、私はあなたのことを指定しているとは思わないいますテーマを使用する必要があります。もしあなたがいたら、それを投稿してください。私たちはもう一度問題を解決しようとします。参考のため、ここに私のテストマニフェストがあります：

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.attributes"> 

    <application 
     android:allowBackup="true"
