为什么不能在&QUOT上下文菜单中工作;记事本"教程? [英] Why doesn't the context menu work in the "Notepad" tutorial?
问题描述
我通过记事本教程中的开发人员指南给出工作: http://developer.android.com/guide/tutorials/notepad/index.html
I'm working through the 'notepad' tutorial given in the developer's guide: http://developer.android.com/guide/tutorials/notepad/index.html
由于某些原因,我使用他们的解决方案的文件,即使,上下文菜单没有拿出我的列表条目点击并按住
For some reason, even when i'm using their solution files, the context menu does not come up with i 'click and hold' on a list entry.
本类扩展ListActivity,并呼吁registerForContextMenu(getListView());
The class extends ListActivity, and calls "registerForContextMenu(getListView());"
但我从来没有看到上下文菜单中火。
but I never see the context menu fire.
任何想法有什么错呢?
推荐答案
他们铺陈行该教程的方式意味着你只能实际上使文本选择,而不是仅仅排它的。你是pressing行本身吗?
The way they lay out the rows in that tutorial means that you can only actually make a selection on text, not just the row it's on. Are you pressing on the row itself?
您可以修复使用的,而不是WRAP_CONTENT中的LinearLayout和在notes_list.xml的layout_width属性的ListView FILL_PARENT,并在里面notes_row.xml TextView的
You can fix that by using fill_parent instead of wrap_content in the layout_width attributes of the LinearLayout and ListView in notes_list.xml, and in the TextView inside notes_row.xml
