【问题描述】：

我在 android attrs.xml 文件中添加了一个用于不同颜色深浅的​​属性。在styles.xml 文件中，我为这些属性赋予了颜色，因此每种样式的颜色都不同。

属性.xml：

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

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>

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"/>

然而，

当我用正常颜色更改属性时，如下所示，它可以工作。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？

【问题讨论】：

  • 您运行的是哪个版本的 Android？我在 Android O（测试版）中遇到过类似的情况，但很少发生。
  • SDK 25 也有类似的问题。
  • 这个问题是不可重现的。
  • 我的问题是我的应用程序没有使用 AppCompat 主题。由于 Thimo 如上面的代码所示这样做，这里的问题似乎是另外一回事。
  • 当我使用 android:background="?selectableItemBackground" 扩展布局时会发生这种情况

标签： java android attributes android-appcompat


【解决方案1】：

您在哪里定义要使用“AppThemeNight”？我用您的代码建立了一个小项目，并定义“AppThemeNight”将在清单中使用，一切都按预期工作。当我在清单中删除对“AppThemeNight”的引用时，应用程序出错并出现以下错误：

原因：java.lang.UnsupportedOperationException：无法解析索引 13 处的属性：TypedValue{t=0x2/d=0x7f0200c9 a=-1}

这就是我认为您所看到的，所以我认为您没有指定应该使用您的主题。如果您是，请发布，我们将再次尝试解决该问题。作为参考，这是我的有效测试清单：

<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>

【讨论】：

  • 还可以在 catch 块日志中获取更具体的信息 exception.getMessage()
  • 是的，我已经在 Menifest 中指定了我的主题，但仍然遇到同样的问题。还有别的事吗？请帮忙:(
