Background technology
Android is widely used Embedded Mobile open source operating system, has the mobile terminals such as more than one hundred million mobile phones, panel computers at present and has made this operating system.In android system, separate between each application program, application program is then referred to as task after running.System provides built-in nearest task manager, for freely switching between the different task run.Simultaneously, production firm generally is Android terminal and is equipped with original input system with main screen key (Home), Menu key (Menu), back spacer (Back), search key (Search) 4 standard operation keys (also claiming function key), controls terminal with person easy to use.
Here front and back switch and refer to that the priority operation order according to the nearest task of terminal switches: be switched to a upper task from current task and be and switch forward; And switch back current task again from a upper task and be and switch backward.
In routine use; people usually can run into and in current task, process before affairs will switch back certain task or switch back the situation of current task again from certain task before; in terminal use procedure, switch nearest task if want, following 3 kinds of modes of operation can be had at present:
Use nearest task manager: first, length is pressed main screen key (Home) and is recalled task manager graphical interfaces, find the task icons needing to switch in the nearest task listed at graphical interfaces again, finally the position clicked on touch-screen residing for task icons switches.This mode needs user's multi-pass operations, and needs to search in numerous task icons with the naked eye on graphical interfaces, there is the shortcoming of the low and poor user experience of efficiency.
Repeatedly short in back spacer: repeatedly short by back spacer, current task is exited after, be switched in a task.Although this mode does not need to search in numerous task icons of naked eyes on graphical interfaces, press back spacer because needs are repeatedly short, still there is the shortcoming that efficiency is not high.In addition, because back spacer only can carry out back operation, make this mode only can forward and can not task switching backward.
Use combination operation: this is the mode that more existing improvement opportunity schemes provide, and needs user in the given time, draws corresponding gesture on the touchscreen or connects by former input keyboard or streak multiple button.When gesture, connect by or streak after operation is identified and just can be switched in previous task.Although this kind of mode efficiency is higher, but due to the operating habit of gesture identification success ratio heavy dependence user, and connecting by needing the response of terminal system delay to each button with the identifying of streaking operation, this type of mode can not bring good Consumer's Experience.In addition, because these technical schemes are only have made some improvements in interactive mode, still task switching backward cannot be realized.
