问题描述

My App widget has a TextView that it's text changes in interaction with user.Now how I can Retrieve Text from it in run time?

推荐答案

你不能.应用小部件是只写的:您可以向它们推送数据，但不能读取它们.

You can't. App widgets are write-only: you can push data to them, but you cannot read them.

相反，当您使用新文本更新应用小部件时，您需要将该文本存储在某个地方，也许是在一个文件中.

Instead, when you update your app widget with new text, you will need to store that text somewhere, perhaps in a file.
