【detailed description】

The present invention will be described in detail below with reference to the specific embodiments and drawings.

Please refer to FIG. 1, which is a schematic flowchart of a first embodiment of a display method of a menu of the present invention. The display method of the menu includes the following steps:

S101. Receive an enable signal for enabling a menu.

S102, displaying a menu in a ring shape, the menu includes at least one concentric ring, each concentric ring is used to display a setting item of the first level menu; when a setting item is selected, if the selected setting item has a next level menu, The next level menu is displayed in a concentric ring shape, and the concentric rings of the next level menu are nested with the concentric rings of the previous menu.

For example, in the nested concentric rings, the outer concentric rings are a first-level menu, and the adjacent inner concentric rings are secondary menus, and so on. Of course, it may also be the innermost concentric ring as a first-level menu, and the adjacent outer concentric rings are secondary menus and the like. When the setting item on the first level menu is selected, if the selected setting item has the next level menu, the second level menu is displayed in a ring shape in the concentric ring of the first level menu. If the selected setting item does not have the next level menu, the function of the selected setting item is directly called.

Different from the prior art, the present invention can maximize the setting by setting the menu to a concentric ring shape. Items are concentrated in one interface. The multi-level menu is displayed by a plurality of concentric rings, and the plurality of concentric rings are nested with each other, so that the multi-level menu can be displayed at the same time, the entire setting can be completed in one interface, and the interface is not required to be switched, thereby reducing the repeated jump of the interface. It also simplifies the operation, making the operation more convenient and quick. Moreover, the concentric ring-shaped menu makes the display of menu items at all levels more intuitive and beautiful. In this embodiment, the concentric annular menu is a circular ring. Of course, in other embodiments, the menu option may also be set to a polygonal manner, such as a triangle, a quadrangle, a pentagon, or a hexagon, etc., specifically It is preferably a regular polygon or the like.

In addition, the embodiment can also set a circular or polygon free switching mode at the same time, thereby intelligently setting according to the size of the display interface, enriching the user experience.

Referring to FIG. 2, it is a schematic flowchart of a second embodiment of a display method of a menu of the present invention. The display method of the menu includes the following steps.

S201. Receive an enable signal for enabling the menu.

S202, displaying a menu in a ring shape, the menu includes at least one ring, each ring is used to display a setting item of the first level menu; when a setting item is selected, if the selected setting item has a next level menu, The next menu is displayed in a ring shape, and the ring of the next menu is nested with the ring of the previous menu. A disc knob is located in the center of the ring. And, a position is preset as a selected position on the ring where at least the first level menu is located, and the setting item at the selected position is the selected setting item.

For example, when there are two levels of menus, the first level menu is displayed on the outer ring and the second level menu is displayed on the inner ring. The disc knob is used to indicate the setting items of the secondary menu on the inner ring. If the position at the bottom of the ring is preset to the selected position, the setting item at the lowest position is the selected setting item. The selected setting item can be highlighted, for example by changing the color, highlighting, or adding a circle to highlight.

In the step S202, the manner of selecting the setting item of the menu of the selected position at least one level includes selecting the setting item to be selected to be the selected position by at least one of clicking and sliding the ring.

Specifically, when the operation is a click setting item, it is determined by the coordinates of the click whether the user clicks on the setting item, and if not, no operation is performed. If yes, the selected item is automatically rotated to The selected location, such as the lowest position.

When the operation is a sliding ring, the user directly slides the setting item to be selected to the selected position, that is, at the lowest position of the ring.

In addition, you can also use the disc knob to select the setting item, specifically the rotary disc knob to point to the setting item to be selected. The disc knob can be provided with a raised dot, a line or an arrow as an indicator. Of course, the indicator can also be set on the disc knob by engraving, drawing or pasting.

If the selected setting item has the next level menu, the ring of the next level menu is displayed in the menu circle, and the setting item of the level menu is displayed on the ring of the next level menu. For example, if the photo size item in the Camera application is selected in the first menu of the outer ring, the inner ring can display the value that the photo size can be set, for example, 1M, 2M, 3M, 5M, 8M, etc., where 1M is 1 million pixels, 2M is 2 million pixels, and so on. Alternatively, you can also display Large, Medium, and Small in the inner ring. The Large item can correspond to 6M, the Medium item to 3.3M, and the Small item to 1.5M. Of course, the corresponding pixel size of each item can be set according to the actual situation.

If the selected setting item does not have a next-level menu, the function corresponding to the selected setting item is called. For example, when 1M is selected in the inner ring and the terminal determines that the setting item has no next-level menu, the next ring will not be displayed, but the function of the setting item is called, that is, the photo size is adjusted to 1M.

Please refer to FIG. 3 , which is a schematic diagram of a menu display interface according to a third embodiment of the display method of the menu of the present invention.

In this embodiment, the present invention is described by taking a menu display in a Camera application of a touch screen mobile phone as an example.

In this embodiment, the step of receiving an enable signal for enabling the menu of the Camera application, that is, when the user wants to set the parameters of the Camera, clicking the set button, the mobile phone receives the enable signal of the click setting button to enable the menu.

The step of displaying the menu, that is, the ring menu pops up in the screen of the mobile phone, the ring menu is divided into an outer ring 30 and an inner ring 31 which are nested with each other, the outer ring 30 is a first level menu, and the inner ring 31 is a second level menu. The item displayed most frequently is displayed by default. When one level menu of the outer ring 30 is selected, the inner ring 31 displays the corresponding one. Secondary menu.

In this embodiment, each setting item of the outer ring 30 is a small picture. According to the setting items, each item is attached to the outer ring 30 at equal intervals. In theory, 20 items can be placed. When one setting item of the first menu of the ring 30 is selected, the inner ring 31 displays a secondary menu corresponding to the first level menu setting item.

Common Camera settings and settings are shown in Table 1.

Table 1.

Setting item	Settable value
		ISO	Auto, 100, 200, 400, 800, 1600
Exposure value	-3,-2,-1,0,+1,+2,+3
		Timed photo time	3s, 5s, 10s, off
Photo size	1M, 2M, 3M, 5M, 8M
		Shutter sound	On,off
Photo mode selection	Auto,night,Hdr,panorama,make up, etc.
		flash	Auto, on, off, torch

As above, these setting items are the most commonly used setting items. As can be seen from the above table, these setting items are simple ways to select one value, or two simple choices, on or off. It can be used as a setting item for the first level menu, and the settable value is used as the setting item of the second level menu. As mentioned above, the first level menu can theoretically accommodate nearly 20 setting items, so it is more than enough for the Camera setting items, and the second level menu is generally within 10 items, which is also sufficient.

Referring to FIG. 3, the entire setting interface mainly includes an outer ring 30 and an inner ring 31 for displaying data, and a disk knob 32 at a central position of the inner ring. These three sections correspond to three custom Views: CircleLayout, InnerCircleLayout, and Rotate View. The principle of CircleLayout and InnerCircleLayout are basically similar. The children of CircleLayout are evenly displayed along the outer ring. These sub-items can be Any view, but in this embodiment, the image view is mainly used. In this embodiment, the lowest position is defined as the selected position 300, and the setting item of the selected position 300 is defined as the setting item indicated by the operation signal. It is the child in the set state. The secondary menu corresponding to the setting status sub-item is displayed on the inner ring 31. The children of the inner ring InnerCircleLayout are mainly TextView, and the TextView is used to display the value of the secondary menu item. The adjustment knob RotateView at the center of the inner ring 31 is a picture. RotateView recognizes the user's swipe operation and simulates the rotation of the spin button to adjust the value of the secondary menu. The setting interface also includes a fourth portion 33 for displaying information of the current setting item.

When you need to display the setup menu, Camera will pass in all the available settings (see Table 1). To do this, you need to build a data adapter Arra Adapter<ListPreference> for the ring. The contents of ListPreference are as shown in Table 2:

Table 2

Please refer to FIG. 4 , which is a schematic diagram showing the position of the menu display interface setting item of the display method menu of the present invention. The ListPreference series is provided by Camera and its contents are shown in Table 1. After CircleLayout obtains the data content through the Adapter, it calculates the position of the setting item relative to the CircleLayout center according to the number of setting items to be loaded, that is, the center is taken as the center, and the selected position 300 in the figure is taken as the starting point. Draw the picture of each sub-item to the ring at an equal angle. The setting item located at the selected position 300 is the item currently in the setting state, the item is marked as CenterItem, the degree of the CenterItem on the ring is 0 degree, the CenterItem is highlighted, and the corresponding waiting is displayed in the secondary menu InnerCircleLayout. Assume Set value. As shown in Figure 4, the sub-item currently in the set state is ISO. There are 6 values to be set under the setting item mEntries={auto, 100, 200, 400, 800, 1600}, and these six values are respectively used as the value of TextView. Also, according to the CircleLayout method, it is sequentially drawn onto the InnerCircleLayout, and the selected value "200" is highlighted. Finally, RotateView, RotateView is the internal member of InnerCircleLayout. The center of RotateView, InnerCircleLayout and CircleLayout are overlapped. As shown in Figure 3, when InnerCircleLayout draws the value to be set, RotateView is drawn together. RotateView points the pointer to The selected value is "200" and the position is recorded.

In this embodiment, the selected operation of the setting item of the outer ring 30 may be a click setting item or a sliding outer ring.

The following describes the operation of clicking the setting item.

Please refer to FIG. 5 , which is a schematic diagram of the operation of determining the setting item indicated by the operation signal in the display method of the menu of the present invention when the setting item is clicked. Specifically, when the user makes a click event on the outer ring 30, CircleLayout's onSingleTapUp function is triggered, and onSingleTapUp determines whether the user clicks on the setting item by clicking the coordinates, and if not, does not operate, otherwise the clicked item will The position of the CenterItem is automatically rotated, and the clicked child is defined as mTappedView. When the mTappedView is rotated to the position of the CenterItem, the mTappedView picture is set to be highlighted, and the secondary menu is displayed to the inner ring 31.

Further, the selected item that is clicked is automatically rotated to the bottom of the ring as follows: First, the outer ring 30 is centered on the CircleLayout center, and a circle is formed with a specified radius, and each item is drawn in a circle in equal arcs. On, starting with the starting child CenterItem, each sub-item has its own degree. At this time, calculate the difference between the degree of mTappedView and CenterItem, as shown in Figure 5. By calculation, the degree of the selected item is 240°, and CenterItem The difference of 0 degrees is 240°. Since it can be rotated to the position of CenterItem clockwise or counterclockwise, it is prescribed to rotate to the CenterItem with the shortest path. When the difference is greater than 180°, it is taken up, in this embodiment. The 240° complement is 60°, so it only needs to rotate 60° clockwise to reach the CenterItem position. The key java code for rotation is as follows:

While(startAngle<destAngle){

startAngle+=velocity/75;

Velocity*=1.0666F;

}

Among them, velocity is the rotation speed, startAngle is used to assist the increment of velocity, its initial value is 0, and destAngle is the target degree, which is 60° of the above example. The function of this step is to divide 60° into a short segment and a small segment. Move the menu one step at a time to achieve the purpose of animation. The degree of each segment is different. The larger the velocity, the larger the degree of increase. This can show the speed from fast to slow until the stop.

The following piece of code is the inverse of the previous code. Each time, velocity/75 converts the velocity to the degree of rotation that needs to be rotated, and passes the degree to the rotateButton function, which sets each setting item on the basis of the original degree. Increase or decrease the incoming degree, then call the draw function, redraw the menu, then velocity/=1.0666F, the speed becomes smaller, and repeat the above steps until velocity/75<3°. When mTappedView is rotated to the position of CenterItem, notifyRotateFinished() is called to notify InnerCircleLayout to update the secondary menu to the secondary menu of the current mTappedView, and the click event is completed.

If(Math.abs(velocity)>5&&allowRotating){

If(rotateToCenter){

If(!(Math.abs(velocity)<200&&(Math.abs(angle

-firstChildPos)%angleDelay<2))){

rotateButtons(velocity/75);

Velocity/=1.0666F;

CircleLayout.this.post(this);

}else{//hongqi

notifyRotateFinished();

}

}else{

rotateButtons(velocity/75);

Velocity/=1.0666F;

CircleLayout.this.post(this);

}

}

Please refer to FIG. 6 , which is a schematic diagram of a setting interface of a display item of the menu of the present invention for determining an operation item indicated by an operation signal by sliding an outer ring. The operation of sliding the outer ring is described below. This operation is mainly to rotate the outer ring by sliding the finger, the process includes releasing the front part of the finger and releasing the two parts of the finger:

Before releasing your finger, do the following in the onTouchEvent function:

Case MotionEvent.ACTION_MOVE:

Double currentAngle=getAngle(event.getX(), event.getY());

rotateButtons((float)(startAngle-currentAngle));

startAngle=currentAngle;

Break;

In the function getAngle, through the formula Math.asin(y/Math.hypot(x,y))*180/Math.PI, calculate the angle of the current finger sliding coordinates x and y with respect to the center of the circle, and then directly call the rotateButtons function. The angle of the finger movement redraws the CircleLayout, which completes the animation during the finger swipe.

After releasing the finger, if the finger slides faster on the CircleLayout, the program calculates the speed at which the finger is released, then converts the speed to the initial velocity of the CircleLayout rotation, and then enters the decreasing redraw thread of velocity, if the velocity is large enough When CircleLayout is possible It will rotate a lot of circles. When the velocity is reduced to 0, the bottom setting item is not aligned with the CenterItem position. Then you need to move the setting item closest to the CenterItem to the CenterItem position again, and then notify InnerCircleLayout to update the secondary menu. The event is over.

The secondary menu corresponds to the secondary menu of the item in the first level menu that is in the set state. When the layout of the CircleLayout changes, its notifyRotateFinished will be called. This function notifies the InnerCircleLayout that the item is currently set, and passes the corresponding ListPreference; the InnerCircleLayout gets the mEntries value in the ListPreference, for example, mEntries={auto,100, 200,400,800,1600}, InnerCircleLayout will use these values as the display content of the TextView, and set the position ID of these values (such as the position ID of auto to 0 and the position ID of "1600" to 5) to the TextView. A total of six TextView, and then draw the TextView onto the InnerCircleLayout. The specific drawing process has been described above and will not be described here.

The selected item of the secondary menu is highlighted. There are two ways to select the sub-menu of the second-level menu. One is to rotate the circular button to point to the corresponding value. If the circular button pointer does not point to the value and then the finger is released, the rotary button automatically switches to the nearest distance. The position of the value; the second is to directly click the corresponding value, then the circular button will automatically rotate to the position of the corresponding value.

Clicking on the setting value means that the value on the menu is directly clicked in the inner ring to make the value in the selected state. When a TextView is clicked, the position ID value corresponding to the TextView is obtained, and then the Camera setting function is called back, and the corresponding ID value is returned to complete the setting.

Rotate the disc knob to point to the set value by sliding the RotateView on the InnerCircleLayout.

Please refer to FIG. 7 , which is a schematic diagram of a setting interface of a menu for determining a setting indication of an operation signal by rotating a disk knob. The implementation of sliding RotateView: When the finger clicks on the RotateView, the center of the RotateView is taken as the center, and the degree of the clicked point in the circle is calculated by the arctangent function, which is recorded as currentdegree. After the finger starts to slide, the coordinates of the finger click start to change. The degree of the corresponding degree is calculated every time the coordinates are updated, and the degree of the current slip can be obtained with the degree-currentdegree. The number increment, using this increment to rotate the RotateView and redraw, completes a slide. If it slides continuously, the RotateView will follow the finger all the time, and the whole process forms the effect of the slide knob RotateView. When the finger is released, the current degree of the knob is converted to the index value of the set value. The conversion method is: rotateView calculates the arc of each optional setting value in the circle according to the number of optional setting values. For example, when mEntries={auto, 100, 200, 400, 800, 1600}, there are six options. When the value is set, the degree of auto is 0°, and in order, 100 is 60°, 200 is 120°, 400 is 180°, 800 is 240°, and 1600 is 300°. If the degree of RotateView is 289° when the finger is released, it can be seen that 289° is between '800' and '1600', but 289° is closer to '1600', so the converted position ID is 5, and the pointer of RotateView at this time. Does not point to '1600', you need to rotate the RotateView 11°, and then click the same as the click setting, callback Camera's setting function, and return the corresponding ID value to complete the setting.
