Abstract

The invention discloses a method for locking and unlocking a screen of a mobile phone with an Android system. The method comprises the following steps that: 1) a system presets a triggerable screen locking signal and stores a triaxial angular value and an acceleration value of the mobile phone of the triggerable screen locking action in a memory; and 2) a gravity sensor triggers the screen locking; and the Android system receives the triaxial angular value and the acceleration value of the mobile phone through an application program interface (API) of the gravity sensor in real time, compares the triaxial angular value and the acceleration value of the mobile phone with those of triggerable screen locking stored in the system respectively and executes the screen locking operation if all the differences of the six values are in a given range. In the method, the screen is locked and unlocked by using the gravity sensor through the action of the mobile phone, so that the method is simple to realize and convenient to use and can prevent error operation as much as possible.

Description

technical field [0001] The invention relates to the field of mobile phone applications, in particular to a method for locking and unlocking a screen on a mobile phone with an Android system. Background technique [0002] When the mobile phone is not in use, it is often affected by certain factors and misoperation occurs. Because the mobile phone keyboard is often exposed, and with the wide application of touch-screen mobile phones, there is a function of locking the screen keyboard. Current touch-screen mobile phones also have this problem, and touch-screen mobile phones are more sensitive and are more likely to be affected by misuse, so an efficient and simple lock screen mechanism is very important. [0003] There are two main types of existing screen lock technologies, namely button screen lock and action screen lock. Button-type screen lock is a commonly used screen lock method for ordinary mobile phones, and the screen is locked by pressing a specific combination of k...
