How to understand the interactive characteristics of Android Pad, in view of this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Android Pad has the same multi-size problem as Phone. For Pad, what is more worrying is the diversity of screen scale and size, which directly affect the performance of UI. What is confusing is how to design an Android Pad application that takes into account a variety of screen sizes, resolutions, proportions and orientations. For this reason, we ask ourselves what is the difference between Android Pad and Phone? What's the difference between Android Pad and iPad?

It is difficult to find a product that represents Android Pad (uncertain size, button location, number). Here is only the picture below to show the mysterious Android Pad.

Mysterious and changeable Android Pad

The first question: how did Pad become Pad? Here I summarize the difference between Pad and Phone:

PadPhone

Size 5 inch-10 inch 2 inch-5 inch application scene home, used for entertainment in the office environment, demonstrating a continuous, long-term immersive and smooth experience in your pocket and more fragmented in terms of carrying time. Touch the screen interactively, click and drag. Touch the screen, click, drag. The hand-holding method is generally held with both hands, but can be operated with the help of the knee, also known as laptop. The left hand holds, the right hand operation is more one-handed operation is more common. It can be said that it is in the palm of the hand. The operation time is long, the operation time is short over half an hour, mostly less than 3 minutes, and the operation frequency is high. Most of the display direction takes into account both horizontal and vertical direction. Most of them are vertical direction information display hierarchical page + pop-up menu structure. Less full page switching, local information switching Screen + popup box page to page switching Screen to screen, page to another page switching content enough space to show more content and functions. There is more explicit content and function. Space is limited, some functions and content are cleverly hidden, such as the content is stitched together through subordinate pages. The function is hidden in menu or in the context menu. Keep the page showing more content.

In addition, many domestic brands under the Android Pad are in 7 inches to 8 inches, the resolution of 800 × 480 accounted for the vast majority. Physical buttons are different.

The current characteristics of Android Pad are as follows:

At present, most Android Pad run system versions for mobile phones.

The dimensions are basically divided into 3 sizes, 5 inches (dell streak), 7 inches (more), and 10 inches (more). The screen resolutions of 800x480and 1024 × 600are the most. The screen ratio is 16, 10, 10, 17, and 10, which is not the traditional 4:3 ratio, which is quite different from iPad. Number and location of physical keypad

The aigo Pad E700 button is placed on both sides of the narrow side.

General trend: there are 1, 3 and 4 in number, but most of them are placed on the narrow side of the screen, and physical keys are rarely scattered.

The default direction of the screen is mostly horizontal, and only the 7-inch screen represented by Samsung is vertical by default.

The layout scheme of Android Pad

Note: the following layout scheme is based on Android 1.5 to 2.2 systems and may not be suitable for Android3.0.

◆ Design for widescreen

◆ Design for horizontal direction: the vertical direction of widescreen is difficult to accept because different applications consider different default directions.

◆ Design for two-handed operation and single right-handed right-handed operation

In view of the large number of widescreen terminals, the information layout can be planned as follows.

◆ Status bar: as the intended object for information notification and task switching, it is indispensable on pad.

◆ double-column layout: the left side is the application level navigation, and the right side is the subordinate page.

◆ Page: including page title, content area, more functional operations on the right.

◆ Popup box: the pop-up box that appears in the operation appears near the action button (figure popup box). At the bottom of the information pop-up box is more functional operation area.

◆ Dialog box: you can also pop up a dialog box above this information pop-up box, which is the judgment and selection of some functions and attributes.

◆ Toast: weak toast-style prompts may also appear on top of the dialog box.

These are the popular Android Pad on the market recently, most of which are installed on systems ranging from 1.6 to 2.2, and such systems are thought to be Android systems barely used on large screens on small screens.

What is Android doing with the big screen?

The Future of Android Android 3.0 Honeycomb

The system that will run Android for Pad 3.0 is characterized by the elimination of physical keystrokes and the placement of home pages, returns, and menus on the screen for more flexible intention objects.

MOTO XOOM loads Android 3.0. we can see that the system is characterized by the cancellation of physical buttons and the placement of home pages, returns, and menus on the screen as a more flexible intention object. The benefits are obvious:

◆ supports more directions at will, and is no longer restricted by keystrokes. Pad can display the application interface in four directions.

The ◆ global home screen, menu and return button can be customized according to the application properties, and the presentation of the application is more flexible.

◆ implements a full-touch interface that no longer relies on physical buttons.

3.0 is a brand new operating system designed for large screens, especially tablets. Emphasis on real, holographic interface design, is an elegant, content-focused interaction mode. It still inherits Android*** 's multitasking, powerful notification mechanism, custom home screen, tools, etc., and carries these features through the lifelike 3D experience and deeper interaction.

Compared with previous systems, the change in layout lies in the bar at the top and bottom.

The ◆ system bar (System Bar), located at the bottom of the screen, corresponds to the global status and notification system. Similar to the status bar at the top of previous versions, but with features such as multitasking.

◆ operation bar (Action Bar): located at the top of the screen in the application, it is the specific operation function of the application.

◆ 3.0 has a wealth of connections, USB, WIFI, Bluetooth. A more efficient connection protocol has been added so that you can directly connect devices such as cameras to synchronize media files.

A series of standard applications have been updated, such as the curved interface of browsers that support multiple Tab; cameras, and the dual-column design of contacts and emails. It is worth mentioning that the interaction of multi-selection and drag is realized in the list operation.

Contact and email use double-column design

Multi-select and drag interaction

Pad's larger screen can show more content, can accommodate more functions, but also can add more interactive actions, which is worthy of our study. In addition, the Android Pad system will also show a two-track status quo: the most commonly used Android1.6 to 2.2 system and the newly released 3.0 system. Dual tracks are bound to increase the complexity of Android as a whole. In addition, the business overlap between Chrome OS and Android, which is used in Notebook, also casts a shadow. It is still worth considering whether Web App can be directly used in Android Pad to reduce the cost of each development team.

This is the answer to the question on how to understand the interactive characteristics of Android Pad. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
