java.lang.UnsupportedOperationException : Failed to resolve attribute at index 13: TypedValue{t=0x2/d=0x7f010046 a=-1} 异常

Question

我在 android attrs.xml 文件中添加了一个属性，用于不同的颜色深浅。在 styles.xml 文件中，我为这些属性指定了颜色，因此它们对于每种样式都是不同的。

属性.xml:

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

样式.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>

膨胀自定义微调器布局:spinner_layout_adapter.xml:

<?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"/>

但是，

当我像下面这样用正常颜色更改属性时，它起作用了。属性 ?attr/normalBackground 似乎不起作用。

android:background="@color/colorPrimary"

有人知道我做错了什么吗？

Answer 1

您在哪里定义要使用“AppThemeNight”？我用你的代码建立了一个小项目，并定义了“AppThemeNight”将在 list 中使用，一切都按预期工作。当我在 list 中删除对“AppThemeNight”的引用时，应用出现以下错误:

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

这就是我认为您所看到的，所以我不认为您指定应该使用您的主题。如果是，请发布，我们将再次尝试解决该问题。作为引用，这是我有效的测试 list :

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppThemeNight">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
