A method and device for realizing virtual keys of an Android system intelligent terminal

Abstract

The invention discloses a virtual press key realization method and device of an Android system intelligent terminal. The method comprises the following steps of detecting whether the Android system intelligent terminal has the root authority or not; when the condition that the Android system intelligent terminal has the root authority is detected, judging whether the current application obtains the root authority or not; after the condition that the current application obtains the root authority is judged, determining the virtual press key function to be realized; obtaining key value code corresponding to the virtual press key function; creating and executing a shell instruction corresponding to the key value code; after the shell instruction is successfully executed, calling and executing the preset jar base file so as to perform reflection calling of an injection virtual press key function through the main function of the jar base file, wherein the jar base file stores files required for realizing the virtual press key functions; after the reflection calling of the injection virtual press key function is successful, realizing the virtual press key function. The method has the advantages that the virtual press key functions can be conveniently realized; low cost, flexibility and reliability are realized.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method and device for realizing a virtual button of an Android system intelligent terminal. Background technique [0002] The keys of smart terminals, especially smart phones, are usually set at fixed positions on the mobile phone. For example, at the bottom of the screen, there are: return key, menu key and home key. Users can only execute corresponding functions by clicking these areas. These buttons are the most frequently used by users. After long-term use, these areas tend to be insensitive or invalid, which makes the mobile phone difficult to operate and use. Users can only spend money to replace the screen or buy a new mobile phone, resulting in large economic loss. [0003] In the prior art, a method for realizing a virtual key is provided, including: receiving a command for generating a virtual function key; generating a virtual function key acco...

AI Technical Summary

Problems solved by technology

It can be seen from the analysis that this method pre-defines the command of the virtual function key, and then sends different virtual key commands according to the position of the focus, thereby replacing the physical key, realizing the operation of the focus point through the virtual key, and solving the problem that the physical key does not work. The problem of adapting to the touch screen mobile phone of the Android system, but there are also certain problems in this implementation method: the virtual function key command needs to be defined in advance, this operation requires system permissions to be realized, and it needs to be pre-integrated into the mobile phone ROM, which needs to be integrated with the mobile phone It can only be realized through the cooperation of manufacturers. In addition, pre-defining the commands corresponding to virtual keys increases storage costs and is not conducive to maintenance.
