如何在Android中解决用户界面问题？ [英] How Can I Solve User Interface Problem In Android ?

问题描述

伙计们。我是Android编程的新手。

当我想在（XML）中设计我的UI时，我遇到了问题。

我的问题是当我在Nexus7中运行我的应用程序（800 * 1280 hdpi）时一切都很好。

但如果我将AVD更改为Nexus One（480 * 800 hdpi）它向我展示了不同的东西！

我使用dp单位进行布局和输入，使用Sp单位进行字体处理。

但是我说它没有显示正确的用户界面！

我的代码：

 <   LinearLayout     xmlns：android   =  http： //schemas.android.com/apk/res/android\" 
   
           xmlns：tools   =  http://schemas.android.com/tools        
   
           android：layout_width   =  match_parent  
   
           android：layout_height   =  match_parent  
   
           android：paddingBottom   =  @ dimen / activity_vertical_margin  
   
           android：paddingLeft   =  @ dimen / activity_horizo​​ntal_margin  
   
           android：paddingRight   =  @ dimen / activity_horizo​​ntal_margin  
   
           android：paddingTop   =  @ dimen / activity_vertical_margin  
   
          工具：上下文  = 。MainActivity          
   
           android：remo ved   =  @ color / color_name_1  
   
           android：orientation  < span class =code-keyword> =  vertical
