不同屏幕尺寸的 Android 布局

Question

I am struggling for layouts for an Android app. I have defined different layouts for different screen sizes and the current layout directory structure is something like this:

• layout
• layout-land
• layout-small
• layout-xlarge
• layout-xlarge-land

Problem

The main layout directory files are being displayed for 3.7 to 7.0 which is a very broad range. And text overlap on small screens and if I adjust on small; it becomes very tiny on the large screen.

According to me, the layout small files should be rendered for smaller screens but those files are only rendered for android wear devices.

layout-xlarge seems to work for Nexus 9 to Nexus 10

I want to know, how can I define the different layout for 3.7-5.0 and 5.0-7.0 screen sizes.

Answer 1

The answer is already given by user5594218 but looks like you are still unclear. (maybe you are beginner)

So, here is the step by step guideline

Solution 1: (short and simple)

1. Navigate to app > src > main > res

2. Duplicate layout directory by copying and pasting

3. Rename duplicated Directories eg layout-sw300dp

Solution 2: (bit lengthy)

1. Create new resource directory: res > New > Android resource directory

2. Select Resource Type as layout

3. Add sw<N>dp in Directory name eg layout-sw300dp and Hit OK

4. Navigate to app > src > main > res

5. Copy layouts XML file inside new directory

   //repeat process for other qualifiers

List of Qualifiers to support all screens:

• layout-sw300dp
• layout-sw330dp
• layout-sw480dp
• layout-sw600dp
• layout-sw720dp

Testing:

This is how it gonna look like, if you did it right.

Answer 2

Create folders like the following

layout-sw300dp
layout-sw330dp
layout-sw480dp 
layout-sw600dp 
layout-sw720dp 

Create also values-folders like

values-sw300dp 
values-sw330dp 
values-sw480dp
values-sw600dp
values-sw720dp

Answer 3

导航应用程序- > res-> 布局并右键单击然后新建-> 布局资源文件正确写入文件名并从可用限定符中选择您想要的大小。

Answer 4

Dear you don't need to declare layout for various screen. just make single layout for every screen and don't fix the width and height of layout. you have to keep height either match parent and wrap content as well as for width.

Answer 5

您应该在 layout-height/layout-width/textsize 中尝试 dp，因为它与屏幕尺寸无关。

Answer 6

尝试使用百分比相对布局。
