Abstract
The invention discloses a mobile phone screen unlocking method based on an Android platform. The mobile phone screen unlocking method is further based on a mobile phone screen unlocking device. Steps of the mobile phone screen unlocking method include 1, recording a coordinate point assembly PS of a user control; 2, recording a touch trace L of the user control; 3, adopting a coordinate point on the L as a center point and gathering all coordinate points in a radius R range into a coordinate point assembly LS; 4, calculating intersection of the coordinate point assembly LS and the coordinate point assembly PS of the user control, and reassigning the value of the intersection as zero; and 5, calculating ratio of the number of the coordinate points with the values of 1 in the coordinate point assembly PS of the user controls to the number of coordinate points in a coordinate point assembly S in a touch screen, judging that an unlocking event occurs if the ratio is smaller than a preset threshold value K, and finishing the current process if the ratio is not smaller than the preset threshold value K. If the ratio of the number of the coordinate points of an unerased portion of the analog user control to the number of total coordinate points of the touch screen of a mobile phone is smaller than a certain threshold value, unlocking is successful; and if the unlocking condition is not met, locking is still kept. The mobile phone screen unlocking method based on the Android platform is low in error operating rate and convenient in operation, and meets experiences of users.
