At present, when a screen is clicked by multiple fingers, if a lifting event of one finger is not uploaded to a host, the host considers that a current key is not released all the time, and other touch data are not processed, so that a false dead state occurs, a user mistakenly considers that a vehicle is dead, and user experience is influenced; in addition, the car machine is in the in-process of assembly debugging hot plug, and the mistake is touched the operation very easily and is appeared, makes and is touched the button and is in unreleased state always, leads to the mistake to judge the product as the defective products.
Based on this, the method, the device, the terminal device and the medium for identifying the touch screen operation provided by the embodiment of the invention can avoid the problem of a false death state caused by unstable data, and improve the user experience.
To facilitate understanding of the present embodiment, first, a detailed description is given of an identification method of a touch screen operation disclosed in the embodiment of the present invention, which may be executed by a terminal device with a touch screen, such as a smart phone, a computer, an iPad, a vehicle-mounted entertainment system, and so on, referring to a flowchart of an identification method of a touch screen operation shown in fig. 1, which illustrates that the method mainly includes the following steps S101 to S103:
step S101: acquiring touch data of a touched key in a touch screen; the touched keys are a plurality of keys which are touched simultaneously.
In one embodiment, when a plurality of fingers simultaneously click on a screen, touch data of a plurality of touched keys can be acquired, wherein the touch data of each touched key comprises: a touch ID, touch coordinates and a touch identifier of the touched key, the touch identifier indicating a touch state of the touched key, such as: when the touch flag is 1, the touch state of the corresponding touched key is a pressed state. In addition, the number of touched keys, namely the hand index of simultaneously clicking the screen, can be acquired.
Step S102: and analyzing the touch data of each touched key in sequence to obtain the touch state of the touched key, and reporting the touch state of the touched key to an operating system.
In an embodiment, the touch state of the touched key may be obtained through analysis based on the touch identifier of each touched key, and the analyzed touch state of the touched key is reported to the operating system.
Step S103: and when the last touch data is analyzed and the touch state of the touched key obtained by analysis is a target state, changing the touch state of each touched key into a release state, and reporting the release state of each touched key to the operating system.
Specifically, in the embodiment of the present invention, when the current analyzed touch data of the last finger is and the touch state is the target state (such as the release state), all the acquired touched keys are released again, that is, the touch state of each touched key is changed to the release state, and the release state is reported to the operating system, so that each touched key is released, and a false dead state is avoided.
According to the identification method for touch screen operation provided by the embodiment of the invention, when a plurality of fingers click screen keys, touch data of each touched key can be normally reported to an operating system; meanwhile, when the last touch data (namely the received touch data of the last finger) is analyzed and the touch state is the target state, all the received touched keys are released again (namely the touch state of each touched key is changed into the release state), so that the normal state can be recovered even if the host does not receive the release state in the touch data, the data instability is avoided, and the user experience is improved.
In an embodiment, in order to facilitate analysis and processing of the acquired touch data, the method provided in the embodiment of the present invention further includes: and storing the acquired touch data of the touched key into a cache region. Based on this, in the embodiment of the present invention, data may be sequentially read from the buffer area according to the touch ID of the touched key for analysis and processing.
Further, in order to ensure that the host system can be normally used, before analyzing the touch state of each touched key, touch coordinates need to be judged to determine that the user clicks an effective area of the touch screen, and a touch message can be normally received. In particular, the method can be realized by the following modes including but not limited to: and judging whether the touch ID of the touched key is a valid ID or not based on the touch coordinate of the touched key.
In a specific embodiment, whether the touch coordinate of the touched key is within the resolution range of the touch screen or not can be judged; if yes, determining that the touch ID of the touched key is a valid ID; if not, determining that the touch ID of the touched key is an invalid ID.
Further, if the touch ID of the touched key is a valid ID, the touch data of the valid ID is analyzed to obtain the touch state of the valid ID. Specifically, the touch identifier of the valid ID may be analyzed to obtain the touch state of the valid ID, and the touch state and the touch coordinate are uploaded to the operating system together.
And if the touch ID of the touched key is the invalid ID, changing the touch state of the touched key corresponding to the invalid ID into the release state. Specifically, touch data of an invalid ID may be filtered out, and a corresponding touch state may be changed to a release state.
For example, assuming that three fingers simultaneously click the screen, it can be obtained that the number of touched keys is 3, the touch IDs of the touched keys are ID1, ID2 and ID3, respectively, and the touch coordinate and the touch identifier corresponding to each touch ID. Firstly, touch coordinates corresponding to ID1, ID2 and ID3 are judged, if the touch coordinates of ID1 and ID3 are located in the resolution range of the touch screen, the ID1 and ID3 are determined to be valid IDs, the touch coordinates of ID2 are not located in the resolution range of the touch screen, and the ID2 is determined to be invalid ID; then, the touch state of each touched key is analyzed in sequence, because the IDs 1 and 3 are valid IDs, the touch states of the IDs 1 and 3 can be obtained through analysis according to the touch identifications corresponding to the IDs 1 and 3, the touch coordinates and the touch states of the IDs 1 and 3 are reported to the operating system, and the ID2 is an invalid ID, so that the touch state of the ID2 is changed into a release state.
When the last touch data is analyzed, that is, the touch data corresponding to the ID3 is analyzed, and the touch state corresponding to the ID3 is the release state, all of the IDs 1, 2, and 3 are changed to the release state, and are reported to the operating system.
For convenience of understanding, an embodiment of the present invention further provides another identification method for a touch screen operation, and referring to a flowchart of the another identification method for a touch screen operation shown in fig. 2, it is shown that the method mainly includes the following steps S201 to S207:
step S201: the touch screen communication bus is initialized.
Specifically, the touch screen communication bus is initialized, so that the initialization of the touch data receiving bus is realized, and the communication link is normal.
Step S202: touch data is received.
In one embodiment, the receipt of touch data is handled primarily by an interrupt thread. When the screen notification is received and a touch event is generated, the host reads touch messages of the touch screen through the touch screen communication bus, and puts all the read touch messages into a touch data cache (buffer), namely, obtains touch data of a touched key in the touch screen, and stores the obtained touch data of the touched key into a cache region.
Step S203: judging whether the touch coordinate of the touched key is in the resolution range of the touch screen; if so, step S204 is executed, otherwise, step S207 is executed.
In one embodiment, the acquired touch data includes: the number of touched keys, a touch ID, touch coordinates and a touch identification. After the touch data is acquired, in order to enable the system to work normally, the touch coordinate needs to be judged first, if the touch coordinate of the touched key is located in the resolution range of the current touch screen, the key ID of the touched key is determined to be valid, and if not, the key ID of the touched key is determined to be invalid.
Step S204: and analyzing the touch state of the effective ID, and uploading the touch state and the touch coordinate of the effective ID to an operating system.
Specifically, when the touch coordinate is within the resolution range of the current touch screen, the touch coordinate is considered to be valid, that is, the touch ID of the touched key corresponding to the touch coordinate is valid, so that the touch identifier of the valid ID can be analyzed to obtain the touch state of the valid ID, and the touch state and the touch coordinate are uploaded to the operating system together.
Step S205: judging whether the current effective ID is the last touch ID or not and the touch state is a release state; if so, step S206 is executed, otherwise, the process returns to step S202.
Step S206: and changing the touch states of all the touched keys into release states, and reporting the release states of all the touched keys to an operating system.
Specifically, when a plurality of fingers simultaneously touch the screen module, the number of touched keys (namely, the number of touched fingers) and touch data of each touched key can be acquired, then under the condition that touch coordinates are effective, the touch data of each touched key are sequentially analyzed, when the last touch data is analyzed and the touch state of the touched key obtained by analysis is a release state, the current maximum number of keys (namely, the number of touched keys) is acquired, all keys are sequentially released, namely, the touch state is adjusted to be the release state, and the release states of all the touched keys are reported to an operating system, so that all the touch states in the current system are ensured to be in the release state; and when the touch state does not accord with the judgment condition, continuously waiting for the next frame of touch data.
Step S207: the touch state of the invalid ID is changed to the release state.
Specifically, when the touch coordinate of the touched key is not within the resolution range of the touch screen, the touch coordinate is considered to be invalid, that is, the touch ID of the touched key corresponding to the touch coordinate is invalid. In order to ensure that the touch of the host system is in the release state under the abnormal condition, invalid data can be filtered out, and the corresponding touch state is changed into the release state.
The method provided by the embodiment of the invention can detect the key ID received each time and the corresponding touch state, and inquire the number of fingers pressed by the current key. When a plurality of fingers click, the data can be normally reported to the operating system firstly, and meanwhile, when the touch data of the last key is detected and the touch state is the release state, all keys received historically can be released again, so that the system can be recovered to the normal state after the operation even if the host does not receive the release state of the last group of touch data, the false death problem caused by unstable data to the host is solved, and the touch failure problem caused by hot plugging during the assembly and debugging of the vehicle machine can be improved.
