Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
The present invention proposes a kind of scan method applying the equipment of android system.Fig. 1 is the flow chart of the method specific embodiment.As shown in Figure 1, the method comprises:
Step 101: the main thread starting current active, and in this main thread, registration radio receiver.
In the equipment of application Android system, with user interface interaction be movable (activity).When an activity is in foreground, this activity can be carried out mutual with equipment user, and namely this activity can receive the instruction (as received the action command etc. that user is sent by touch-screen) of user, and then makes certain reaction according to this instruction.The activity being in foreground is called current active in the present invention, and the thread of current active, also referred to as the main thread of current active, only in the main thread of current active, the operation relevant with current active could be performed.
In this step, the main thread of device start current active, and in this main thread, registration radio receiver (BroadcastReceiver).Broadcast is a kind of mechanism of transmission information, and radio receiver then filters broadcast, receive and respond.
Step 102: the bar code of equipment to its outside scans, and scan-data is sent to radio receiver with the forms of broadcasting.
The bar code of equipment to its outside scans, and can obtain scan-data, and this scan-data by the data of this recognition of devices, can be the form of analog signal or digital signal.
Scan-data is sent to radio receiver with the form of broadcast by equipment, when departing from special scanning application software, can realize the transmission of scan-data.
Step 103: radio receiver receives scan-data, and the interior display of the edit box being sent to current active.
Scan-data is sent to radio receiver by step 102, foreground is in owing to only there being current active, thus only have in the main thread of current active and have registered radio receiver, like this, the scan-data also just only having the radio receiver of current active just can receive step 102 to send.
The edit box of current active can identify scan-data and show it.
Step 104: close radio receiver, and then suspend the main thread of current active.
Before the main thread needing time-out current active, first radio receiver will be closed, to save system resource.
Suspend the main thread of current active, namely current active has departed from foreground.
As can be seen here, in the present invention, after starting current active main thread, namely radio receiver is registered, like this, when equipment scans outside bar code, and after the scan-data of acquisition is sent to radio receiver with the forms of broadcasting, radio receiver in current active main thread can obtain scan-data, and then shows in the edit box being sent to current active, thus realizes by the cognition of scanning barcode.Before the main thread suspending current active, first close this radio receiver, can system resource be saved again.As can be seen here, the present invention utilizes broadcast to transmit scan-data, achieves the direct scanning to bar code under the prerequisite departing from application software.
In step 102, the bar code of equipment to its outside scans, and sends to the method for radio receiver to be scan-data: the bar code of equipment to its outside scans, and obtains view data with the forms of broadcasting, this view data can be analog signal, also can be digital signal; This image data analyzing is scan-data by equipment, and scan-data is sent to radio receiver with the forms of broadcasting.
The invention allows for a kind of equipment applying android system, Fig. 2 is the structure chart of this equipment specific embodiment.As shown in Figure 2, this equipment comprises: processor 201, scanning means 202, display unit 203.As shown in Figure 2, processor 201 is connected with display unit 203 with scanning means 202 respectively.
Processor 201 for, run all activities; Start the main thread of current active, and in this main thread, registration radio receiver; The scan-data that scanning means 202 is sent here is sent to radio receiver with the forms of broadcasting; Utilize radio receiver to receive scan-data, and be sent to display unit 203; Close radio receiver, and then suspend the main thread of current active;
Scanning means 202 for, the bar code of outside is scanned, and scan-data is sent to processor 201;
Display unit 203 is for, the edit box of display current active, and display is received from the scan-data of processor 201 in this edit box.
Scanning means 202 in the present invention can realize with camera, also can realize with probe.Here probe can be common scanner, can be also special probe, as bar code scan head.
Processor 201 can be connected by various interface with scanning means 202, as being connected by serial ports, is connected by parallel port, or is connected by various wave point.
Bar code in the present invention can for arbitrarily can by the bar code scanned, as bar code, image etc.Here bar code can be the bar code of any type, as one-dimension code, Quick Response Code etc., all within protection scope of the present invention.
As can be seen here, the present invention has the following advantages:
(1) in the present invention, after starting current active main thread, namely radio receiver is registered, like this, when equipment scans outside bar code, and after the scan-data of acquisition is sent to radio receiver with the forms of broadcasting, the radio receiver in current active main thread can obtain scan-data, and then show in the edit box being sent to current active, thus realize by the cognition of scanning barcode.Before the main thread suspending current active, first close this radio receiver, can system resource be saved again.As can be seen here, the present invention utilizes broadcast to transmit scan-data, achieves the direct scanning to bar code under the prerequisite departing from application software.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
