Mobile phone screen adaptation

With the increasing number of mobile phone screens, some users' mobile phone screens are still in the size of 240*320. Of course, they are also stored in some irregular screen resolution. For many UIS, multiple sets of images can be drawn from different mobile phone screens to ensure that the mobile client matches on different screens. Plan the implementation of the mobile client on different screens, and develop a filling Area algorithm that can calculate the position of the specific control, this is an interface adaptation algorithm for matching different mobile phone screens in the early stage.

First, recognize several cell phone screen areas (starting from 240*320 and 320*240 ):
1. Filling Area
Container: In this standard, the concept of filling area is used to control the interface. The whole page consists of filling areas of different sizes. Different filling areas have different Scaling Rules when they adapt to the screen.
2. Screen
Screen: the size of the visible area under each resolution in the Root Filling Area. The size is equal to the screen resolution of a mobile phone model. For example, in n73, the screen parameter is 240*320.

3. baseline screen
For landscape screens and landscape screens, two sets of landscape screens are used: Landscape screens 240*320 and landscape screens 320*240. You can switch between the two screen types.

Portrait screen 240*320 appropriate screen Scaling:
The screen size of the portrait screen is 240*320, and can be scaled to a size of 480*640. Meet the needs of iPhone, Android, and other users.

Vertical screen font proportional Scaling: when the control adapts to different screens, the control usually needs to scale according to the font.

Principles Followed-headers and tails
In the adaptation process of the regular interface, the principle is to determine the header height first and then the footer height, then, the height of the content filling area is determined based on the screen height and the head and tail height, and the layout of the entire interface is adjusted. The control width is based on proportional scaling.

(Common interface)
(For Android and iPhone touch screens)
(Nokia, kjava, and other keyboard types)

Scaling principle:

When the interface is adapted to different interfaces, two different Scaling Rules are used. Font scaling and proportional scaling are used for different filling areas as needed.

The overall scaling rule is designed based on the adaptive mode of images on different screens. We assume there is an n73 mobile phone with a screen resolution of 240*320, on this phone, you can view a full screen 480*640 image. The mobile phone is displayed as follows (the red box shows the visible area of the screen ):

If we use an e63 mobile phone (resolution: 320*240) for viewing, the effects of different viewing modes are as follows (the red box shows the visible area ):

(Highly adaptive effect)

(Adaptive width effect)

It can be seen from the effect that, if the adaptive width effect is used for zooming, the upper and lower scroll bars can achieve better display effect and ensure that the image content can be clearly viewed. Therefore, the image width is used as an image and the width ratio of different screen resolutions is used to adjust the wallpaper scale the image.

Startup interface:

240*320-320*240:

240*320-Portrait screen extension:

320*240-horizontal screen extension:

General interface:

240*320-320*240:

240*320-Portrait screen extension:

320*240-horizontal screen extension:

On the gongge page, the program automatically sorts the icons, and The beginning and end follow the regular interface adaptation principle.
