是否可以仅制作窗口小部件而制作Android版图？

[英]Is it possible to make an Android Layout, without just widgets?

原文 2010-10-26 17:08:20 9 2 android/ xml/ layout/ widget

Just something I have been thinking about. 只是我一直在想的事情。 It is possible to create an android layout with just a TextView widget and no Layout code (eg: inearLayout, ScrollLayout), but if I try to add anything else to the XML file all sorts of errors start popping up. 可以仅使用TextView小部件而不使用布局代码（例如：inearLayout，ScrollLayout）创建android布局，但是如果我尝试将其他内容添加到XML文件中，则会出现各种错误。 Is it possible to create a Layout with just widgets? 是否可以仅使用窗口小部件来创建布局？

Also, if it is, how? 另外，如果是，怎么办？

I don't think it's possible inside of an XML layout to have a layout of purely widgets and no ViewGroups. 我认为在XML布局内部不可能有仅包含小部件且没有ViewGroups的布局。 You would for one be creating an invalid XML doc (multiple roots since a widget cannot contain other widgets). 您可能会创建一个无效的XML文档（多个根，因为一个小部件不能包含其他小部件）。 Also you need a ViewGroup to hold multiple Views. 另外，您还需要一个ViewGroup来容纳多个View。 You can create a merge and then decide on the view group later, however that is just a substitute for a ViewGroup. 您可以创建一个合并，然后在以后决定视图组，但这只是ViewGroup的替代。 However it is the closest thing to an XML layout with only widgets in it, surrounded by a merge element as the root xml tag. 但是，这是最接近XML布局的东西，其中只有小部件，周围是merge元素作为xml根标签。

Yes it is possible to create layout with a single View (eg TextView ). 是的，可以使用单个 View （例如TextView ）创建布局。 But if multiple Views are required you neeed to wrap them with a ViewGroup (eg LinearLayout ) 但是，如果需要多个视图，则需要用一个ViewGroup包裹它们（例如LinearLayout ）
