我刚开始使用 android home 小部件进行编程,所以我可以通过 settextviewtext() 从我的小部件提供程序将文本设置为 home 小部件中的 textview,但是当我想从中获取文本时,我没有理想.不能像在活动中一样正常使用 findViewById(),然后使用 getText().有没有办法从小部件提供者那里获取主页小部件中的 textview 文本?或者告诉我如何从另一个活动中获得?
I just begin programming with android home widget, so i could set text to a textview in home widget from my widget provider by settextviewtext() but when i want to get text from it, i have no ideal. Can not use findViewById() as normal as in activity and then getText(). Is there any way to get text of textview in home widget from widget provider? Or show me how to get from another activity?

in这个问题说:
你不能.应用程序小部件是只写的:您可以将数据推送给它们,但是你无法阅读它们.
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.
