解决Android布局报错：Failed to resolve attribute at index 1: TypedValue{t=0x2/d=0x7f040007 a=-1}

问题背景

在Android 9平板和Android 13手机上运行自制Android Java应用时，触发报错：resolve attribute at index 1: TypedValue{t=0x2/d=0x7f040007 a=-1}，报错指向布局文件的Toolbar标签，但自闭合标签/>写法合规，尝试常见方案后问题仍存在。

排查与解决方案

核心原因

报错并非自闭合标签/>的问题，而是Toolbar组件类引用错误，导致系统无法解析?attr/actionBarSize属性。布局中直接使用<Toolbar>未指定完整包名，系统无法匹配到正确的组件类，进而无法找到属性定义。

具体解决步骤

修正布局中的Toolbar组件类
由于项目使用了Material组件库（导入了MaterialToolbar），推荐使用MaterialToolbar，也可使用AppCompat的Toolbar，二选一即可：

方案一：使用MaterialToolbar

<com.google.android.material.appbar.MaterialToolbar
    android:id="@+id/nowPlayingTopAppBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:title="   Now Playing"
    app:menu="@menu/top_app_bar_for_now_playing"
    app:titleTextColor="#FFFFFF" />

方案二：使用AppCompat Toolbar

<androidx.appcompat.widget.Toolbar
    android:id="@+id/nowPlayingTopAppBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:title="   Now Playing"
    app:menu="@menu/top_app_bar_for_now_playing"
    app:titleTextColor="#FFFFFF" />

确保主题兼容
检查AndroidManifest.xml中MainActivity的主题是否继承自Material或AppCompat主题，例如：
```
<activity
    android:name=".MainActivity"
    android:theme="@style/Theme.MaterialComponents.Light.NoActionBar">
</activity>
```
这类主题包含actionBarSize等属性定义，若主题不兼容会导致属性解析失败。
验证依赖配置
确认Module级build.gradle中包含必要的依赖：
```
implementation 'com.google.android.material:material:1.9.0'
implementation 'androidx.appcompat:appcompat:1.6.1'
```
版本号可根据项目需求调整，确保依赖存在且版本兼容。
