Only the original thread that created a view hierarchy can touch its views. Expected: android.imms Calling: main

这个错误是由于在一个非UI线程中尝试更新UI视图引起的。Android UI框架是不线程安全的，因此只有创建UI视图的主线程才能更新UI视图。如果你想在其他线程上执行一些耗时操作，你可以使用异步任务(AsyncTask)或者Handler机制来更新UI视图。

Android.imms是一个系统服务，负责处理输入法相关的请求和交互。如果你在非主线程中调用它，也会导致上述错误。为了避免这种情况，你应该在主线程中调用与输入法相关的API。

Only the original thread that created a view hierarchy can touch its views.

This means that only the thread that created a view hierarchy (e.g. the main thread in Android) is allowed to modify or interact with the views within that hierarchy. If another thread attempts to modify a view, an exception will be thrown. This restriction is in place to ensure that views are accessed and modified in a thread-safe manner, preventing potential concurrency issues and ensuring that the user interface remains responsive and stable.

android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

这个异常是因为你在非 UI 线程中尝试更新 UI 控件。 Android 中的 UI 控件只能在 UI 线程中进行更新。你可以使用 runOnUiThread() 方法或者 Handler 将更新 UI 的代码放到 UI 线程中执行。或者你可以使用 AsyncTask，在 doInBackground() 方法中执行后台任务，在 onPostExecute() 方法中更新 UI 控件。
