Android 开发具有100'的应用程序;编辑字段和文本字段的类型
我正在开发一个包含100个文本字段和编辑字段的应用程序。在很多文本中,我使用textwatcher来监听更改和更新其他文本字段。在这个问题上我没有太多的选择,因为许多领域相互依赖。但该应用程序遇到了很多性能问题。它经常结冰。我可以得到一些关于开发文本字段数量惊人的应用程序的提示吗。我认为我使用的所有TextWatcher都在减慢ui线程的速度Android 开发具有100'的应用程序;编辑字段和文本字段的类型,android,android-studio,android-textwatcher,Android,Android Studio,Android Textwatcher,我正在开发一个包含100个文本字段和编辑字段的应用程序。在很多文本中,我使用textwatcher来监听更改和更新其他文本字段。在这个问题上我没有太多的选择,因为许多领域相互依赖。但该应用程序遇到了很多性能问题。它经常结冰。我可以得到一些关于开发文本字段数量惊人的应用程序的提示吗。我认为我使用的所有TextWatcher都在减慢ui线程的速度 //Business Operating Cost TextWatcher businessOperatingCostTextWatc

如何简化主UI线程: 向视图公开ViewModel的一些LiveData,只需在TextWatcher中调用
postValue
。然后它会很快释放
然后,在LiveData observer中,您可以在单独的线程上处理处理,并将结果再次发送到LiveData对象finalOperstingCosts
然后,在该LiveData的观察者中,将文本设置为字段
这样,主线程上就不会有长时间运行的任务。一次只激活一个
TextWatcher
,因此这可能不是原因。检查主线程中是否有其他工作正在进行
