我有一个menucreen XML。当我打开项目宽屏时它不适应所有屏幕尺寸。我怎样才能克服这个问题。

当我想添加关于这个问题的图片时，我想我需要10个代表。点:)）

有人可以帮助我吗？

Answer 1

在android中，为了支持尽可能多的设备，您可以提供一个布局的多个定义。首先，您需要将这些文件夹添加到资源中，对于每个文件夹，您可以指定相同布局的不同xml文件，以满足您希望应用程序使用的设备屏幕。

以下是文件夹结构的示例：

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

res/layout/main_activity.xml           // For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml   // For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml   // For 10” tablets (720dp wide and bigger)

（在应用清单中）

<supports-screens 
        android:smallScreens="true" 
        android:normalScreens="true" 
        android:largeScreens="true"
        android:xlargeScreens="true"  
        android:anyDensity="true"/>

有关支持多个屏幕的更多信息，我强烈建议您阅读有关它的Google文档。 Here是文档的链接。 http://developer.android.com/guide/practices/screens_support.html

Answer 2

声明尺寸值 - 小，值 - 大，值 - xlarge等。

不要忘记在AndroidManifest.xml中声明支持屏幕

 <supports-screens 
        android:smallScreens="true" 
        android:normalScreens="true" 
        android:largeScreens="true"
        android:xlargeScreens="true"  
        android:anyDensity="true"/>

Answer 3

在Android中，您必须根据屏幕尺寸在不同的不同绘图中设置图像，并根据屏幕尺寸进行布局。

res/layout/my_layout.xml(drawable also like layout) ---- default layout. 
res/layout-layout-hdpi/my_layout.xml ---- layout for hdpi screen size 
res/layout-layout-large-hdpi/my_layout.xml ---- layout for large hdpi screen size 
res/layout-layout-mdpi/my_layout.xml ---- layout for mdpi screen size(normal tables also) 
res/layout-layout-Xdpi/my_layout.xml ---- layout for Xhdpi screen Size(high resolution)

Answer 4

You can proceed as following

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

res/layout/main_activity.xml           # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml   # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml   # For 10” tablets (720dp wide and bigger)

res/drawable-mdpi/my_icon.png        // bitmap for medium density
res/drawable-hdpi/my_icon.png        // bitmap for high density
res/drawable-xhdpi/my_icon.png       // bitmap for extra high density


<supports-screens 
        android:smallScreens="true" 
        android:normalScreens="true" 
        android:largeScreens="true"
        android:xlargeScreens="true"  
        android:anyDensity="true"/>
