Android 8.0三星Experience 9.0编辑TextInputEditText时应用崩溃

数据老陈

2026-8-2

Android 8.0三星Experience 9.0系统下EditText编辑已有数据崩溃问题

问题现象：

仅在Android 8.0（Oreo）三星Experience 9.0系统中触发，其他Android版本运行正常
编辑lyrics_editor对应的已有数据时应用必现崩溃，新建编辑器无异常
尝试将控件类型从EditText改为TextInputEditText后，问题仍未解决

解决方案：
该崩溃是Android 8.0三星定制系统的DynamicLayout绘制bug，触发原因是文本绘制时索引越界，可尝试以下修复方式：

禁用硬件加速：
针对lyrics_editor所在的TextInputLayout禁用硬件加速，避免绘制时的索引计算错误：

// 在dialog.show()之前添加
view.findViewById<TextInputLayout>(R.id.lyrics_input_layout).setLayerType(View.LAYER_TYPE_SOFTWARE, null)

文本预处理：
清理已有歌词文本中的异常换行或特殊字符，避免绘制解析错误：
```
val cleanedLyrics = lyrics?.replace("\r\n", "\n")?.trim() ?: ""
lyricsEditor.setText(cleanedLyrics)
```

延迟设置文本：
延迟到视图绘制完成后再设置文本，避免初始化阶段的绘制冲突：

lyricsEditor.post {
    lyricsEditor.setText(lyrics)
    lyricsEditor.textAlignment = View.TEXT_ALIGNMENT_TEXT_START
}

降级Material组件版本：
若使用高版本Material Components，尝试降级到1.4.0等稳定版本，减少新组件与旧系统的兼容性问题。
