Description

Method, device and computing device for adapting application notification color under Android system

Technical field

The present invention relates to the field of Android technology, and in particular, to a method, an apparatus, and a computing device for adapting an application notification color in an Android system.

Background technique

Currently, notifications from devices with Android (Andriod) systems mainly include system default notifications and application notifications. The default notification of the system is customized by the manufacturer. The layout, color background, and font color of the notification are well defined by the system, so the Android device can display the system default notification normally. The application notification is a custom notification issued by an application (APP) installed in the system, and the background color and font color of the notification are set by the application.

Since the manufacturer may prohibit the application installed on the Android system from modifying the notification color when popping up the notification, for example, the background color is prohibited from being modified. Therefore, if the font color of the application notification is close to the background color of the system default notification, the user may not be able to view it. Clear the content of the application notification, affecting the user experience. For example, the default notification color of the Android phone A system is black on white, and restricts other APP pop-up application notifications to modify its background color. If the color of the notification sent by the application B installed on the Android phone A is white on a black background, since the system prohibits the application from notifying the custom background color, the application notification displayed to the user is white on a white background, and the user cannot see the notification of the application. content.

detailed description

Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiment of the present invention has been shown in the drawings, it is understood that Rather, these embodiments are provided so that this disclosure will be thorough and complete.

As mentioned above, since the manufacturer may prohibit the application installed on the Android system from modifying the notification color when popping the notification, for example, prohibiting the application from modifying the notification background color, the background color and application of the system default notification are replaced instead of the display. When the font color of the notification is close, the user cannot see the content of the application notification, thereby affecting the user experience.

In response to this situation, the present invention proposes a solution to construct a system default notification and obtain the font or background color of the system default notification, and select a color matching style that matches the system default font or background color as the default for the application notification. The color matching style is such that the color of the font does not conflict with the background color, so that the user can clearly recognize the content of the application notification.

Embodiments of the present invention will be specifically described below with reference to FIGS. 1 through 3. FIG. 1 shows a functional block diagram of a computing device 100 in accordance with one embodiment of the present invention. The computing device 100 can be any type of computing device on which an Android system is installed, preferably a mobile device, including a mobile computer or mobile computing device (eg, a tablet computer, a personal digital assistant, a laptop computer, a notebook computer, a netbook, etc.), A mobile phone (eg, a smart phone), a wearable computing device (eg, a smart watch, smart glasses, etc.) or other type of mobile device.

As shown in FIG. 1, computing device 100 can include a memory 110 and a processor 120 that is coupled to memory 110. In one embodiment of the invention, computing device 100 may include other components such as a display screen, input and output devices, etc., not shown in FIG. The above and other components may be connected to each other, for example, via a bus. It should be understood that the functional block diagram of the computing device shown in FIG. 1 is for illustrative purposes only and is not intended to limit the scope of the invention. Those skilled in the art can add or replace other components as needed.

The memory 110 is used to store information, which may include color combinations of system default notifications, such as fonts and corresponding background colors. The default font color of the system can be, for example, black, and the background color is white. A plurality of colors of any color space or color gamut can also be stored in the memory 110.

The processor 120 can construct a system default notification to retrieve the system default font or background color from the memory 110. For example, the processor may include a notification construction unit that may generate a system default notification to obtain a layout file ID of the default notification, and the processor may further include a layout generation unit that may generate a layout corresponding to the obtained layout The view container of the file ID, and then traverse the child controls of the view container to get the font color or background color of the system default notification.

The processor 120 can also select a color matching style corresponding to the font or the background color from the memory 110 as the default color matching style of the application notification. For example, when the font color of the acquired system default notification is black, black is selected from the memory 110 as the font color of the application notification. Or when the default background color of the obtained system is white, a color such as black which is significantly different from white is selected from the memory as the font color of the application notification, so that the font color of the application notification does not conflict with the default background color of the system. For user identification.

Thus, the font color of the application notification can be adapted to the system default background color, and the font color of the pop-up application notification is significantly different from the background color of the system default notification, so that the user can easily recognize, thereby ensuring the user's notification reading experience.

It should be understood by those skilled in the art that the above examples are illustrative and not limiting, and the processor may also select other color matching styles from the memory as the default color matching style for application notification. Moreover, when the font or background color of the system default notification acquired by the processor is other colors (for example, white on black background, white on transparent background, etc.), a plurality of matching color matching styles may also be selected as the color matching style of the application notification.

The process of adapting the processor 120 to the application notification color under the Android system can be seen in FIG. 2. 2 shows a flow chart of an adaptation method in accordance with an embodiment of the present invention.

As shown in FIG. 2, in step S210, the system default notification is constructed to obtain the default font or background color of the system.

In Android, Android app message reminders can display notification content in a pop-up box. That is, the system can display the notification content to the user by a Toast that pops up automatically after a few seconds. In order to ensure that the user can recognize the content of the application notification, the application notification needs to be properly matched. For example, the font color of the notification needs to be adapted to the background color in order to provide the user with an easily recognizable and aesthetically pleasing notification.

However, some systems prohibit the app from being free to change the color of its notifications. For example, some systems prohibit the application from modifying the background color of the notification, which causes the app to actually notify you of the font color selected by the app and the default background color of the system. At this time, if the font and the background are the same or similar in color, the notification content will be illegible. If the font and background colors are not similar but not coordinated, the user experience will also be degraded. To do this, you need to know the system's default notification color. The overall color scheme can be inferred simply from its font or background color.

In order to achieve the above object, the solution of the present invention knows the default notification color of the system by constructing a system default notification without actually issuing the notification of the above configuration. In one embodiment, the font color or background color of the system default notification can be obtained by traversing the child controls of the view container by knowing the layout ID of the system default notification and the corresponding view container.

For example, the system default notification A may be generated by a module provided by the system, such as a notification constructor, by the system default notification A's content view and calling its native API to obtain a corresponding layout ID, which is generated using, for example, a layout generator provided by the system. The view container B corresponding to the layout ID of the system default notification, traverses all the child controls of the view container B, finds all the text control list C whose control type is TextView type, and traverses the text control list C to obtain the font color of the system default notification.

Similarly, all child controls of view container B can also be traversed in a similar manner to obtain the background color of the system default notification.

After knowing the font or background color of the system default notification, in step S220, the color matching style corresponding to the system default font or background color may be selected as the default color matching style of the application notification. For example, when the color of the system default font is black, you can select the color style with black font as the default color for application notification, and so on.

In some embodiments, for a font color of different color values, a background of a color matching style matching the color value is designed, and a color matching sample file is formed and stored in a memory of the computer, and the color matching sample is recognized after the font background is recognized. The file selects and calls the corresponding background to complete the matching of the background color, so that the font color matches the background, and the font can be highlighted.

It should be understood by those skilled in the art that the above examples are illustrative and should not be used to limit the present invention. The color scheme of the application notification of the present invention may also be implemented in other manners.

Since there are generally four text controls in the layout file notified by the system default, corresponding to the title, content, time, and information, in the process of traversing the text control list C, it is preferable to directly judge the font color according to a text control. This is because it is often difficult to get the font color information directly from multiple text controls, and the title is the most prominent text control (for example, the title has the largest font and the most prominent color), which can be regarded as the representative of the text color, and thinks The color of the system default font is obtained accordingly. Therefore, for step S210, it is also preferable to obtain the default text color of the system as the default font color of the system.

Thus, when traversing the text control list C, it is necessary to find the text control to which the system default notification target belongs (for example, the text control with the largest font) D, and call the native API of the title text control D to obtain the text color of the title. .

In one embodiment, in the case where the system has a plurality of default color matching styles, these color matching styles may be read in advance to facilitate selection of a matching color matching style according to the font or background color acquired in step S210. Therefore, for step S220, all system notification color matching styles can be acquired, and the specific system notification color matching is selected if it is determined that the font or background color of the system notification is the same or similar to the font or background color of the specific system notification color matching style. Style is the default color style for app notifications.

The specific implementation manner is as follows: calculating a color difference value between the font color and a preset color matching sample; when the color difference value is smaller than a first preset threshold, selecting a color matching style that is the same as or similar to the color matching sample; otherwise Choose a color style that is different from the color sample.

The color sample values are pure black (0,0,0) or pure white (255,255,255). The first preset threshold is 0.5. The color value range of the color matching sample is not limited to this. Depending on the specific application scenario, the value of the color matching sample can be any color value, such as (150, 150, 150), (175, 250, 45) or (15, 58, 241 )Wait. At the same time, the selection range of the first preset threshold is not limited thereto. The value of the first preset threshold can be any value between 0-1, depending on the specific application scenario.

For example, in the case where the title color of the system notification of the learned structure is black, the color matching style in which the title color is the same as black can be selected. If there is more than one color matching style with the title color being black, the text content color and/or the background color can be further compared to select the color matching style with the largest similarity.

Here, the similarity of colors can be judged by introducing the concept of color null. In one embodiment, the similarity may be determined by the font or background color being notified to the particular system by the font of the color-matching style or the distance of the background color within the color space. The color space here can be a color space actually used by systems such as RGB space and CMYK space.

Specifically, the similarity of colors can be judged by the following method.

Suppose there are two RGB colors, Color1 and Color2, which can be converted into two three-dimensional coordinates in the RGB color space, such as Color1 converted to (R1, G1, B1) and Color2 converted to (R2, G2, B2). The coordinate differences of the x, y, and z axes are respectively obtained, that is, Rx=R1-R2, Gy=G1-G2, and Bz=B1-B2. The distance between Color1 and Color2 in the color space can be calculated according to the formula diff=sqrt(Rx*Rx+Gy*Gy+Bz*Bz), where sqrt represents the second square root. The above distance may represent a color difference between the two colors.

Thereby, the system notification color matching style whose background or font is the smallest with the background or font color difference obtained in step S210 can be selected from the acquired system notification color matching style as the color matching style of the application notification.

In a simpler embodiment, it is considered that the system usually has two color schemes of white on black and black on white, so that it can be simply stepped in without having to obtain the color scheme of the system notification in advance. The color obtained by the S210 is closer to pure black or pure white and is directly selected from the white color on black and the black color on white.

For example, you can directly compare the font or background color of the system default notification with pure black, take the obtained font or background color as Color1, and pure black as Color2, and calculate the color difference diff according to the above formula. Subsequently, the similarity formula can be used to determine whether the font or background color of the acquired system default notification is similar to pure black. Here, since the color difference between pure white (255, 255, 255) and pure black (0, 0, 0) is the largest, the color difference diff_max calculated by pure white and pure black can be used as the denominator, and Color1 and Color2 are calculated. The color difference is diff, then the similarity s is calculated as s=(1-diff)/diff_max. The similarity value can be between 0 and 1. The closer to 0, the more dissimilar. The closer to 1, the more similar, the 0.5 can be taken as the critical value. If the similarity is greater than 0.5, the two colors are considered similar. not similar. Therefore, in the case that the font or background color of the system default notification is similar to pure black, the color style of the black text or the background is selected, otherwise, the color style of the white text or the background is selected.

[Application example]

This scheme constructs an instance of the system default notification, which simply uses the title text color of the system default notification as the default font color of the system, and selects black text on white or black on white according to the similarity between font color and pure black. The system color scheme is used as an application notification color. The specific implementation process is as follows:

1. Generate a system default notification A through the notification constructor provided by the system;

2. Obtain the corresponding system default notification layout file ID by notifying A's content view member (content view) and calling its native API (getLayoutId);

3. Using the layout generator provided by the system (LayoutInflater, the role is to generate a view container according to the layout file) to generate a view container B corresponding to the layout file ID of the notification A;

4. Traverse all the child controls of view container B, find out all the text control list C of the control type is Text View;

5. Traverse the text control list C, find the text control D with the largest font size, the control is the title text control of the system default notification;

6. Call the title of the text control D's native API (getCurrentTextColor) to get its text color F;

7. Calculate the similarity between pure black (0,0,0) and text color F by the color difference formula of RGB color. If the text color F is similar to pure black, load the black text style application notification layout, otherwise load the white text style. Application notification layout.

Those skilled in the art will appreciate that the present scheme constructs an instance of a system default notification, but is constructed without actually sending the notification, and is constructed and retrieved only once.
