我应该从layout_weight移动探底？ [英] should I move from layout_weight to dip?

问题描述

我创建了一个小部件。我故意用 layout_weight

I have created a widget. I intentionally used layout_weight

所以它适合任何屏幕尺寸。

so it would fit any screen size.

小部件总是跨越到1X4。

The widget is always spanned to 1X4.

我现在看在不同设备中的图形编辑器，我看到的重量并没有帮助。

I now look at different devices in the graphic editor and I see the weight doesn't help.

我应该搬到沾大小？

的线性布局相对于背景图象不同跨区

The linear-layouts are spanned differently in relation to the background image.

我的XML：

推荐答案

这是明显，因为单布局的普通屏幕大小的设备上完美的工作，并不意味着它会工作在大/ XLARGE屏幕尺寸相同的方式。因此，建立内部资源文件夹布局大或布局XLARGE（根据设备屏幕大小）。同样的布局复制到新创建的文件夹，然后作出一些改变它，所以它会适合大/ XLARGE屏幕按您的要求。你也可以复制图像到LDPI，MDPI，华电国际和xhdpi支持多种密度。

It is obvious because single layout working perfectly on a normal screen sized device doesn't mean that it'll work the same way on large/xlarge sized screens. So create a folder inside res "layout-large" or "layout-xlarge" (depending on device screen size). Copy same layout into newly created folder and then make some changes to it, so it'll fit for large/xlarge screens as per your requirement. Also you may copy images into ldpi, mdpi, hdpi and xhdpi to support multiple densities.
