For example, in an embodiment, the step C may specifically include:
step C01: acquiring the current distance between two contacts, and calculating the difference value M between the current distance and the initial distance between the two contacts;
for example, the current distance and the initial distance are distances of the two contact points in the arrangement direction of the tool keys, for example, the tool keys in the toolbar may be arranged in the height direction of the screen of the interactive display device as shown in fig. 2, or may be arranged in the width direction of the screen, and lengths of the tool keys in the arrangement direction of the tool keys may be the same;
for example, the interactive display device in this embodiment adopts an Android operating system;

when the two contacts slide towards each other, if n is larger than or equal to K, all the tool keys except one tool key in the control toolbar are changed to be not displayed, so that the length of the toolbar is minimum, and if n is smaller than K, the n tool keys currently displayed in the control toolbar are changed to be not displayed;
when the two contacts move away from each other, if N ≧ (N-K), all tool keys which are not currently displayed are controlled to be changed to be displayed so that the length of the toolbar is maximum, and if N < (N-K), N tool keys which are not currently displayed are controlled to be changed to be displayed;
and K is the number of the currently displayed tool keys in the toolbar, and N is the number of the tool keys corresponding to the maximum length of the toolbar in the arrangement direction of the tool keys.
For example, if the interactive display device adopts an Android operating system, a toolbar can be implemented by adding a windows manager, a toolbar is a parent view of a tool key therein, if the tool keys in the toolbar are arranged in the screen height direction of the interactive display device, an icon of the tool key can be hidden or displayed by changing the height of the view of the toolbar (i.e., the parent view of the tool key) (i.e., the length of the toolbar in the arrangement direction of the tool keys), and after the height of the view of the toolbar is changed, the display height of the toolbar can be updated by using mwndowmanager.
For example, a toolbar including 5 tool keys is shown in fig. 2 (i.e., N is 5) when it is fully expanded (all tool keys are displayed), after which a user performs a pinch operation, the folding operation is started after the distance between two fingers decreases by a length l, the tool key one is hidden, the tool keys two, three, four, and five are displayed, the tool key five is hidden after the distance between two fingers decreases by a length l again, the tool keys two, three, and four are displayed, the state of the toolbar is shown in fig. 3, when the distance variation between two contact points reaches 4 l, the control tool key three is displayed, the tool keys one, two, four, and five are hidden, the state of the toolbar is shown in fig. 4, if the distance between two contact points continues to decrease, the tool button three is always kept displayed, namely the toolbar is always kept in the state shown in the figure 4;
if the user touches the view area of the toolbar with two fingers when the toolbar is as shown in fig. 4, then the two-finger unfolding operation is performed, the toolbar starts to perform the unfolding operation after the distance between the two fingers increases by a length l, a currently-undisplayed toolbar key is changed to be displayed, and then every time the distance between the two fingers increases by a length l, the currently-undisplayed toolbar key is changed to be displayed until all the toolbar keys in the toolbar are in the displayed state (as shown in fig. 2), and then if the distance between the two touch points continues to increase, the toolbar always keeps the state of fig. 2;
in addition, in the embodiment of the present invention, the number of toolbars displayed by the interactive display device may be 1, or may be multiple, for example, one toolbar may be provided on each of the left and right sides of the screen.
According to the method for adjusting the toolbar provided by the embodiment of the invention, a user can adjust the number of the tool buttons displayed in the toolbar through gestures, for example, the toolbar is folded when two fingers are kneaded, and the toolbar is unfolded when the two fingers are unfolded, so that the user can conveniently control the number of the tool buttons in the toolbar.
The embodiment of the present invention further provides an interactive display device, including a processor and a memory coupled to the processor, where the memory stores an instruction for the processor to execute, and when the processor executes the instruction, the method for adjusting the toolbar can be implemented, for example, the interactive display device may be a device including a display touch screen, such as a touch-control all-in-one machine, an electronic blackboard, an electronic whiteboard, an intelligent television all-in-one machine, an intelligent interactive large screen, or an intelligent interactive flat panel, or may be a device not including a display touch screen, such as an OPS (Open plug capable Specification, Open Pluggable Specification) device.
