Profile页面随机崩溃求助：IndexOutOfBoundsException异常排查

我有一个个人资料页面，包含若干TextView、EditText和Spinner组件。页面平时运行正常，但偶尔会随机崩溃，而且崩溃属于系统内部问题，堆栈跟踪没指向我Activity文件里的具体代码行，没法确定崩溃原因。

• 检查文本更新逻辑：确保所有TextView/EditText的文本修改都在主线程执行，避免多线程并发修改导致布局计算出错
• 关闭硬件加速：可以在AndroidManifest.xml中给对应Activity添加android:hardwareAccelerated="false"，或者针对单个TextView/EditText调用view.setLayerType(View.LAYER_TYPE_SOFTWARE, null)
• 升级SDK版本：部分旧Android系统的DynamicLayout存在此类bug，升级到较新的目标SDK可能修复系统层面的问题
• 优化文本更新频率：如果有频繁更新文本的操作，合并更新请求或添加适当延迟，减少布局重绘次数
• 捕获异常避免崩溃：继承TextView/EditText，重写onDraw方法，捕获IndexOutOfBoundsException并处理，防止崩溃扩散
