Android layouts for different screen sizes

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.

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 e.g 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 e.g 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.

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

Navigate app-> res-> layout and right click then New-> layout resource file write the filename correctly and from available qualifiers choose the size you want.
