Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0022] Such as figure 1 Shown, JAVA technology is a cross-platform software technology. The JAVA application program (MIDlet) conforming to the J2ME specification can run on different hardware devices after simple adjustment and adaptation (even without adjustment at all), regardless of the processor and operating system details of the hardware device platform.

[0023] The cross-platform feature of JAVA itself depends on its abstract application running environment, that is, the JAVA virtual machine. The core part of the function that implements the JAVA virtual machine is usually called the JAVA kernel (Core), or simply called the JVM.

[0024] When different JAVA applications run on the same hardware device, they need to manage thei...

Abstract

The invention discloses a method for realizing rotation of a JAVA application programming interface (API) with the rotation of a screen. The method comprises the steps as follows: a processor detects that the state of mobile equipment is changed to trigger the screen to rotate; a bottom-layer application program sends a screen rotation event to a platform application layer; the platform application layer controls a local application program to rotate with the rotation of a display interface, and then sends the screen rotation event to a JAVA kernel through a JAVA adaptation layer; the JAVA kernel modifies screen size parameters; the JAVA core calls the screen size of the mobile equipment of the JAVA application program to modify an interface; and the JAVA application program reads new screen size parameters in altering functions of the screen size of the mobile equipment, and refreshes interface display in accordance with the new screen size parameters. By means of the method, the JAVA API can rotate with the rotation of the screen of the mobile equipment by using the minimum development working capacity, so that the mobile equipment with the rotatable screen realizes more complete promotion of user experience.

Description

technical field [0001] The invention relates to the application field of mobile devices, in particular to a method for following the rotation of a JAVA application program interface when the screen rotates. Background technique [0002] In order to provide a richer user experience and adapt to different usage habits, more and more mobile devices support screen rotation, such as triggered by sliding cover or G-sensor or other methods, so that users can switch to horizontal screen at any time according to their preferences display or vertical display. [0003] When the screen rotation is triggered, the local application program developed in the operating platform language in the mobile device can directly receive the trigger event, so as to realize the follow-up rotation of its application program interface, but the JAVA application program in the mobile device, due to the JAVA specification There is no interface definition for screen rotation events. Most JAVA applications a...
