[0046] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

The singular forms "a" and "the" may also include the plural forms.

[0048] Currently, the cursor in traditional Android text controls has not been specially processed. When dragging the cursor, it jumps bit by bit according to the offset of the current text. The cursor position is refreshed every time the offset changes. In this case, the user will feel a noticeable pause and delay.

[0049] To this end, the present application provides a cursor display method, a smart device, and a storage medium.

[0050] A text control is an interface element used to display and edit text.

[0051] Taking Android as an example, TextView is the most common and basic Android text control, used to display text content to the user. The TextView control has many attributes that can be set in XML files, and these attributes can also be declared dynamically in code. For example, you can set the text content, font color, and font size. TextView can also be configured to display clickable links when the text is a URL, email, phone number, or map.

[0052] For example, EditText is another Android text control that is a subclass of TextView. Users can edit an EditText control, meaning they can interact with it to enter or modify its contents. Listeners can also be set for the EditText control to detect whether the user's input is valid.

[0053] It can be understood that the above-mentioned text controls of the present application are not limited to text controls of the Android system, but can also be text controls of other smart device operating systems.

[0054] In order to make the purpose, technical solutions and advantages of this application more clear, the following is a further detailed description of the cursor display method of this application in conjunction with the accompanying drawings and embodiments, taking TextView as an example of a text control. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit the cursor display method described in this application to using TextView as a text control.

[0055] Please refer to FIG1 , which is a schematic flow chart of main steps of a cursor display method according to an embodiment of the present application.

[0056] As shown in FIG1 , the cursor display method in the embodiment of the present application mainly includes the following steps S101 to S103 .

[0057] Step S101: Acquire a first position based on a touch operation of a user, where the touch operation is the user touching a touch screen of a smart device, and the first position is a corresponding position of a finger on the touch screen.

[0058] The smart device in this application can be a mobile phone, a tablet computer, a personal computer (PC), a personal digital assistant (PDA), a smart watch, a netbook, a wearable electronic device, an augmented reality (AR) device, a virtual reality (VR) device, a vehicle-mounted device, a smart car, a smart speaker, a robot, etc. This application does not impose any special restrictions on the specific form of the smart device.

[0059] The smart device includes at least one touch screen. When a user touches the touch screen of the smart device, the smart device generates a touch event (TouchEvent). The touch event listener of the smart device can obtain detailed information about the touch event, including the horizontal coordinate (X value) and vertical coordinate (Y value) of the touch point in the touch screen coordinate system. As shown in FIG2 , the position (X, Y) of the touch point is shown in the screen coordinate system.

[0060] Step S102: determining a second position based on the first position, where the second position is the position of the cursor in the view coordinate system of the text control.

[0061] The view coordinate system of a text control is the positional relationship between a subview (such as a TextView or EditText text control) and its parent view. In this coordinate system, the top-left corner of the parent view is defined as the origin (0, 0). For smart devices, this origin corresponds to the top-left corner of the touchscreen, with positive directions pointing to the right horizontally and downward vertically. The view coordinate system shown in Figure 2 can be used as an example.

[0062] The second position is the position of the cursor in the view coordinate system of the text control determined by calculation.

[0063] Step S103: updating the display of the current frame cursor based on the second position.

[0064] In this application, a frame refers to a single image that constitutes a continuous dynamic image. The current frame cursor can be understood as the cursor that the user sees and operates at any given moment. When the user drags the cursor, the cursor moves continuously on the screen, forming a series of position points. These position points can be analogized as a continuous "frame" in the visual effect of real-time interaction.

[0065] Specifically, the current frame cursor is redrawn according to the position of the cursor in the view coordinate system of the text control, and the drawn current frame cursor is displayed.

[0066] When drawing a cursor, create a graphical element to represent the cursor, such as a vertical line (|) or an I-beam. Use the text control's drawing API to draw the cursor at the calculated cursor coordinates.

[0067] Based on the above steps S101-S103, first, a first position is obtained based on the user's touch operation, where the touch operation is the user touching the touch screen of the smart device, and the first position is the corresponding position of the touch operation on the touch screen; based on the first position, a second position is determined, where the second position is the position of the cursor in the view coordinate system of the text control; and based on the second position, the current frame cursor is updated. In this way, the second position of the cursor in the view coordinate system of the text control (the position of the finger on the touch screen) is accurately calculated, which means that the cursor is no longer limited to bit-by-bit jumping between text characters, but can move continuously and smoothly according to the touch action, thereby achieving a more intuitive and natural user interface interaction experience. In the traditional way, the cursor only refreshes its position when the text offset changes, resulting in an obvious sense of pause and delay. However, the present application can achieve real-time tracking of the user's touch action and immediately update the display position of the current frame cursor, so that the user hardly feels any delay when dragging the cursor, thereby enhancing the smoothness and comfort of the operation.

[0068] The above steps S102 to S103 are further explained below.

[0069] Specifically, the above step S102 can be implemented through the following steps S1021 to S1023.

[0070] Step S1021: determining a position offset based on the first position, where the position offset is a position offset of the finger in the view coordinate system.

[0071] Specifically, when processing a touch event, the text control can convert the touch point of the touch event into a relative position in the TextView (that is, the position offset of the finger in the view coordinate system) by calling convertToLocalHorizontalCoordinate() of the text control TextView, where the touch point is based on the screen as the reference system.

[0072] Alternatively, the position offset may be determined in the following manner.

[0073] In a specific embodiment of the present application, determining the position offset based on the first position includes: acquiring a text layout object of the text control; and determining the position offset based on the first position and the text layout object.

[0074] Specifically, by obtaining the layout object of the text control TextView and calling the getOffsetForHorizontal() of the layout, the word closest to the touch point is found in the text layout of the TextView. That is, the offset position of this word relative to the first word in the text layout of the TextView is the position offset.

[0075] Exemplarily, taking Figure 3 as an example, when the user touches the word "种", the word closest to the touch point is the word "种". At this time, the word "种" is divided into two equal widths on the left and right. When the touch point is within the left half (left one - half) width range of the word "种", the position offset is 1. When the touch point is within the right half (right one - half) range of the word "种", the position offset is 2. When the user touches the middle position between the word "一" and the word "种", the word closest to the touch point can be "一", and the determined position offset is 1.

[0076] Step S1022: Determine the third position based on the position offset. The third position is the current line where the finger is in the text layout of the text control. In the text layout of a text control (such as TextView or EditText), the current line refers to the line where the cursor is or the line of text that the user is currently focused on when the text content is displayed.

[0077] In a specific embodiment of the present application, the determining the third position based on the position offset includes: obtaining the text layout object of the text control; and determining the third position based on the position offset and using the text layout object.

[0078] The text layout object (Layout object) of the text control is a class responsible for managing the text layout and measurement in the text control. In Android development, the Layout object can calculate the display method of the text, including the number of lines of the text, the start and end positions of each line, the width and height of the text, etc.

[0079] Specifically, first obtain the text layout object of the text control, and then call the getLineForOffset(offset) of the layout object of the TextView to obtain the current line where the touch operation is in the text layout of the text control.

[0080] Step S1023: Determine the second position based on the first position and the third position.

[0081] Specifically, step S1023 can be implemented through the following steps S10231 to S10233.

[0082] Step S10231: Determine the boundary information of the current row based on the third position.

[0083] The boundary information of the current row may include a top position and a bottom position of the current row in the view coordinate system.

[0084] Specifically, first obtain the text layout object, that is, the Layout object, call getLineTop(line) to obtain the top position of the current line in the view coordinate system, and call getLineBottom(line) to obtain the bottom position of the current line in the view coordinate system.

[0085] Step S10232: Determine the horizontal coordinate of the cursor in the view coordinate system based on the first position.

[0086] Specifically, call convertToLocalHorizontalCoordinate() of TextView to convert the X value of the touch point to the relative position x in TextView. The relative position is the left value, which is the horizontal coordinate of the cursor in the view coordinate system.

[0087] Step S10233: Determine the second position based on the boundary information of the current row and the horizontal coordinate of the cursor in the view coordinate system.

[0088] Specifically, the bottom position of the current line in the view coordinate system is used as the bottom position of the cursor, the top position of the current line in the view coordinate system is used as the top position of the cursor, the horizontal coordinate of the cursor in the view coordinate system is used as the left position of the cursor, and the horizontal coordinate of the cursor in the view coordinate system plus the width of the cursor is used as the right position of the cursor.

[0089] In this way, the position of the cursor in the view coordinate system of the text control can be accurately obtained according to the position of the touch point in the screen coordinate system, which is conducive to achieving the effect of the cursor moving smoothly following the finger.

[0090] The above is a further description of step S102 , and the following further describes step S103 .

[0091] Specifically, step S103 can be implemented through the following steps S1031 to S1032.

[0092] Step S1031: Determine the position of the current frame cursor based on the second position and the width of the cursor.

[0093] Generally speaking, the cursor can be a vertical line (|) or a flashing mark of an I-block. Taking the vertical line (|) as an example, the width of the cursor is very small, usually just the width of a pixel, which represents an insertion point in the character stream. The height of the cursor usually matches the height of the currently used font so that the user can clearly identify the position of the cursor in the text. For the I-block cursor, the width of the I-block cursor is generally slightly larger than one pixel to make it easier to notice. It usually covers the width of one or more characters, and the specific width can be adjusted according to design needs. Similarly, the height of the I-block cursor should also be consistent with the height of the current font to ensure that the cursor can completely cover the vertical space of the character. The width of the cursor can be adaptively adjusted according to the actual application scenario, or it can be set according to the user's preferences. There is no specific limitation on this.

[0094] Specifically, according to the second position and the width of the cursor, the specific position where the cursor should be drawn in the current frame can be set through setBounds.

[0095] Exemplarily, the bottom position of the current line in the view coordinate system is used as the bottom position of the cursor, the top position of the current line in the view coordinate system is used as the top position of the cursor, the horizontal coordinate of the cursor in the view coordinate system is used as the left position of the cursor, and the horizontal coordinate of the cursor in the view coordinate system plus the width of the cursor is used as the right position of the cursor. At this time, the cursor position can be obtained as setBounds(left,top,left+width,bottom).

[0096] Step S1032: redrawing the current frame cursor based on the position of the current frame cursor.

[0097] Specifically, according to the specific position of the current frame cursor that has been set, invalidateCursor() is called and the current frame cursor view (View) is redrawn so that the new current frame cursor position can be displayed correctly.

[0098] In a specific embodiment of the present application, before determining the second position based on the first position, the method further includes: determining whether the cursor is dragged based on the user's touch operation.

[0099] As shown in Figure 4, when a touch event is received by the smart device (S201), the text control (e.g., TextView) processes the touch event (S202). Specifically, it first determines whether the cursor of the text control is being dragged (S203). If so, the position of the current frame cursor in the view coordinate system of the text control is determined according to the method of the aforementioned embodiment (S204); if not, the position of the current frame cursor in the view coordinate system of the text control is not determined. For example, if the user only touches the position of the current frame cursor with a finger but does not perform a drag action, the position of the current frame cursor in the view coordinate system of the text control is not determined. Finally, if it is determined that the cursor is being dragged, the cursor is drawn during the dragging process according to the position of the cursor (S205).

[0100] Specifically, when the cursor is dragged, the cursor's property value mIsDraggingCursor is set to true. When dragging ends or stops, the cursor's property value mIsDraggingCursor is set to false. Therefore, by determining the specific state of the cursor's property value mIsDraggingCursor, you can confirm whether the cursor is being dragged. In this way, you can accurately determine whether the cursor is being dragged.

[0101] In one embodiment, as shown in FIG5 , the cursor display method may be implemented specifically through the following steps S2041 to S2046 .

[0102] S2041: When the cursor is determined to be dragged, a touch operation is received and an offset of the touch event in the TextView is calculated based on the touch event position. If the offset is different from the previous offset, the offset of the current finger touch position in the view coordinate system of the TextView is updated. Specifically, Selection.setSelection() may be called to update the current offset.

[0103] S2042: Determine the current line of the touch operation in the text layout of the text control according to the offset in the text control TextView.

[0104] Specifically, getLineForOffset(offset) may be called to obtain the current line of the touch operation in the text layout of the text control.

[0105] S2043: Determine the bottom position and top position of the current row in the view coordinate system according to the current row.

[0106] Specifically, the top position of the current line in the view coordinate system is obtained by calling getLineTop(line), and the bottom position of the current line in the view coordinate system is obtained by calling getLineBottom(line).

[0107] S2044: Determine the horizontal coordinate of the cursor in the view coordinate system according to the position of the touch event.

[0108] Specifically, call convertToLocalHorizontalCoordinate() of TextView to convert the X value of the touch point to its relative position in TextView. This relative position is the horizontal coordinate of the cursor in the view coordinate system.

[0109] S2045: Setting the cursor position of the current frame according to the bottom position bottom and the top position top of the current line in the view coordinate system, the horizontal coordinate of the cursor in the view coordinate system, and the cursor width.

[0110] For example, the position of the current frame cursor can be set by setBounds(left, top, left+width, bottom).

[0111] S2046: Call invalidateCursor() to redraw the current frame cursor.

[0112] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effect of the present application, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present application.

[0113] Furthermore, the present application also provides a cursor display device.
