Adjusting method for button functions in electronic device and related apparatus
An adjusting method for button functions, used in an electronic device having a plurality of buttons respectively corresponding to at least one key value, is disclosed. The method includes determining an angle of the electronic device corresponding to a predefined direction; and adjusting the relationship between each of the plurality of buttons and the at least one key value according to the angle.
1. An adjusting method for button functions, used in an electronic device comprising a plurality of buttons arranged in a first button order relative to a predefined direction and respectively corresponding to at least one key value all arranged in a first key value order when the plurality of buttons are in the first button order, the method comprising:
determining an angle of the electronic device corresponding to the predefined direction; and
reversing all of the plurality of buttons from the first button order to a second button order and maintaining the key values in the first key value order relative to the predefined direction when the angle is determined to be greater than a predefined angle, such that the plurality of buttons have different corresponding key values when the buttons are arranged in the second button order compared to when the buttons are arranged in the first button order, wherein the plurality of buttons are located at a same side of the electronic device, and wherein the at least one key value is associated with at least one function of the electronic device;
wherein the at least one function comprises increasing volume and decreasing volume;
wherein an amount of the plurality of buttons is more than 2.
2. The adjusting method of claim 1 , wherein the predefined direction is a gravity direction.
3. The adjusting method of claim 1 , further comprising when the angle restores from being larger than the predefined angle to being smaller than the predefined angle, reversing the plurality of buttons from the second button order to the first button order and maintaining the key values in the first key value order relative to the predefined direction.
4. An electronic device, comprising:
a plurality of buttons, arranged in a first button order relative to a predefined direction and corresponding to at least one key value all arranged in a first key value order when the plurality of buttons are in the first button order;
an angle detector, for detecting an angle of the electronic device corresponding to the predefined direction; and
a control module, coupled to the plurality of buttons and the angle detector, reversing all of the plurality of buttons from the first button order to a second button order and maintaining the key values in the first key value order relative to the predefined direction when the angle is determined to be greater than a predefined angle, such that the plurality of buttons have different corresponding key values when the buttons are arranged in the second button order compared to when the buttons are arranged in the first button order, wherein the plurality of buttons are located at a same side of the electronic device, and wherein the at least one key value is associated with at least one function of the electronic device;
wherein the at least one function comprises increasing volume and decreasing volume;
wherein an amount of the plurality of buttons is more than 2.
5. The electronic device of claim 4 , wherein the predefined direction is a gravity direction.
6. The electronic device of claim 4 , when the angle restores from being larger than the predefined angle to being smaller than the predefined angle, reversing the plurality of buttons from the second button order to the first button order and maintaining the key values in the first key value order relative to the predefined direction.
