java - 修改 Settings.apk 以使用 Project Glass

Question

我正在尝试构建 Settings.apk 以在 Google I/O 的 Hacking Glass session 上用于 Glass:https://www.youtube.com/watch?feature=player_detailpage&v=OPethpwuYEk#t=500s

他提到为了让设置 apk 工作，需要修改 list 中的一行。这是 AOSP list :

http://pastebin.com/2yQ3QEgX (由于篇幅已添加到pastebin)

每次我运行设置应用程序时，它都会崩溃，这是 logcat 输出:

对于 list 中应该修改哪些内容才能使其正常工作，有什么想法吗？

Answer 1

对于来自 ICS MR1 分支的设置 apk，除了删除 AndroidManifest 中的 sharedUserId 字段...

您看到的崩溃是因为 holder 的图标和摘要字段为空。com.android.internal.R.layout.preference_header_item 是一个简单的 TextView。

如果你换入 R.layout.preference_header_switch_item，并隐藏开关，它应该可以工作。
