如何在 appwidgetprovider 中查找视图 ID? [英] How to find view id in appwidgetprovider?

问题描述

我有一个从 appwidgetprovider 扩展的 appwidget.

I have a appwidget extends from appwidgetprovider.

我创建了一个名为 main_layout.xml 的布局 xml 文件并添加了一个按钮.如果我开发一个 listActivity，我会通过以下路径到达此按钮:R.layout.main_layout.button01.

I have created a layout xml file named main_layout.xml and add a button. If i develop a listActivity i reach this button with this path: R.layout.main_layout.button01.

(Button)findViewById(R.layout.main_layout.button01)

Activity 类有一个名为 findViewById() 的成员方法，但 appwidgetprovider 没有.

Activity class has a member method that named findViewById() but appwidgetprovider has not.

如何到达布局中的按钮?

How can i reach my button in my layout?

对不起我的英语

推荐答案

您永远不能直接在 Appwidget 中引用或修改视图.您应该在 RemoteViews 中执行此操作.

You can never reference or modify views in Appwidget directly. You should do this in RemoteViews.
