问题描述 #

在Android 7.1.1设备上运行应用时，突然出现视图膨胀异常，报错为：Error inflating Binary XML file line #53: Error inflating class com.google.android.material.textview.MaterialTextView。尝试将MaterialTextView替换为TextView后问题仍未解决，按钮组件也出现相同异常。

问题根源分析 #

从堆栈最底层的ArrayIndexOutOfBoundsException可以看出，问题出在系统读取资源字符串时索引越界，说明编译生成的资源文件可能损坏，或者资源引用存在错误，导致视图初始化时无法正确读取所需资源。

解决方案 #

• 清理并重建项目：执行Android Studio的Build -> Clean Project，再执行Build -> Rebuild Project，或者用命令行运行./gradlew clean assembleDebug，清除编译缓存并重新生成资源文件。
• 检查资源完整性：排查所有XML布局文件、strings.xml、colors.xml等资源文件，确保没有未闭合标签、特殊字符，以及所有引用的资源（如@color/black）都存在且拼写正确。
• 适配依赖版本：Android 7.1.1对应API 25，检查com.google.android.material:material库的版本是否兼容。如果使用了过高版本，尝试降级到兼容API 25的版本（如1.6.1）。
• 清除设备缓存：卸载应用后，进入设备设置的应用管理清除残留缓存，再重新安装最新编译的APK。
• 调整资源压缩配置：如果开启了shrinkResources true，检查proguard-rules.pro或res/raw/keep.xml，确保必要的资源没有被误删，避免运行时找不到资源导致索引越界。
