[0042] The puipose, technical proposal and advantages in the examples of the present disclosure will become more clear and complete from the following detailed description when taken in conjunction with the appended drawings. Apparently, the examples described thereinafter are merely a part of examples of the present disclosure, not all examples. Persons skilled in the art can obtain all other examples without creative works, based on these examples, which pertains to the protection scope of the present disclosure.

100431 Inventors of the present disclosure have found in the process of research and practice, the prior art has technical problems at least as follo s: up to date the content displayed in the draggable listv iew is static and dynamic content cannot be displayed; for example, the items in the draggable listview of a music player can only display the fixed information such as song name and singer, but it can not display the synchronized lyrics of the son being played. This makes the content displayed in the draggable listvie is relatively plain and affects the using experience of the draggable listview for the user.

100441 Fig. 1 is a flowchart of an example of a method for refreshing the content of a draggable list vie of the present disclosure. The method may be applied to the dev ices with touch screen, especially to the smart terminals, such as smart phones, tablet computers and so on. Steps of Fig. 1 may be performed by processor 1 - 10 to execute instructions stored in memory 1 - 12. Referrin to Fig. 1 , the method can comprise:

[0045] Step l OO(SlOO), determining, by a processor, whether the draggable listview is dragged by a user; if not, go to Step 1 10( S 1 10); if yes, go to Step 1 20( S 120); [0046] An object (such as a user's finger, a touch pen etc.) can perform the drag operation on the draggable listview. When the object is performing a down— move at a designated position of an item on the draggable listview, then we will say, the object is performing a drag operation on the draggable listview, and the draggable listview is being dragged.

[0047] In an optional example, the method can modify the source code of the drag operation, for example, define a flag bit in the source code of the drag operation, wherein the flag bit is used to indicate whether the draggable listview is being dragged or not. Specifically, the value of the fla bit tells whether the draggable listview is being dragged.

100481 When a dra operation performed by an object is detected, the value of the flag bit is set to a first value, for example, the value of the flag bit is set to true to indicate the draggable listview⁷ is being dragged. When no drag operation is detected, the value of the flag bit is set to a second value, for example, the value of the flag bit is set to false to indicate the draggable listview is not being dragged.

100491 It should be understood that setting the first value to true and setting the second value to false is just an available option. The first value may also be set to 1 and the second value may be set to 0. The examples of the present disclosure make no limitation on how⁷ to set the specific values of flag bit.

100501 As mentioned above, when an object is performing a down-move at a designated position of an item in the draggable listview, that is to say, the object is performing a drag operation on the draggable listview. Therefore, in the examples of the present disclosure, the flag bit having the first value is corresponding to an object triggering a down event in the draggable listview, the flag having the second value is corresponds to an object triggering an up event in the draggable listview⁷.

[0051] Step 110(S110), triggering, by the processor, a thread to refresh the content of items in the draggable listview at a preset refreshing frequency.

[0052] Optionally, by triggering a thread, a timer that controls the refreshing frequency may be set in the thread. Owning to the timer, this example can use a handler provided by an operating system to tell a main U I thread to refresh a data source of the draggable listview's adapter at a preset refreshing frequency, so as to refresh the content of the items of the draggable listview.

[0053] In order to refresh the content of the items of the draggable listview in real-time, the examples of the present disclosure may provide the following insurance mechanism to ensure the real-time:

100541 If the data source is local data, identifying a refreshing content relevant to the items of the draggable listview according to a position marker of the local data, using a handler provided by an operating system to tell a main UI thread to refresh the content of draggable listview items with the refreshing content at a preset refreshing frequency.

100551 Taking the draggable listv iew in the music player for example, due to the data source is local data, the local storage lyrics have the marks of song playing time, which may be matched w ith that of the songs currently playing (the positioning marking the local data is the song playing time mark). Therefore the lyrics corresponding to current playing time may be achieved from the lyrics of local storage and furthermore the real time refreshing of the lyrics in the draggable listview of music players may be realized.

100561 If the data source is internet data, using a handler provided by the operating system to tell the main UI thread to refresh the content of the items of the draggable listview with the latest internet data acquired from the internet at a preset refreshing frequency.

[0057] In an optional example, when the flag bit having the second value is detected, the method goes to Step l l O(SH O), i.e. triggering a thread to refresh the content of the items of the draggable list v iew at a preset refreshing frequency.

100581 Step 120(S 120), triggering, by the processor, the thread to stop refreshing the content of the items in the draggable listv iew, performing, by the processor, a drag operation in the draggable listview, after the dragging operation is finished, triggering, by the processor, the thread to refresh the content of the items in the draggable listview at the preset refreshing frequency.

100591 Because refreshing the content of the items of the draggable listview and performing a drag operation in the draggable listview both need to be executed by the main UI thread, if refreshing the content of the items of the draggable listview and performing a drag operation in the draggable listview at the same time may easily lead to a stuck or a pause on the display interface of a touch screen apparatus, which may affect the user^'s experience.

100601 Therefore, when the draggable listview being dragged is detected, the examples of the present disclosure w ill trigger a thread to stop refreshing the content of the items of the draggable listview, and only perform the drag operation in the draggable listview; once the dragging operation is finished, go to Step 1 10( S 1 10 ), i.e., trigger a thread to refresh the content of the items of the draggable list view at a preset refreshing frequency.

100611 In an optional example, when the flag bit having a first value is detected, the method can go to Step 20( S 1 20), i.e. triggering a thread to stop refreshing the content of the items of the draggable listview, then performing the drag operation in the draggable listview, once the dragging operation is finished, triggering a thread to refresh the content of the items of the draggable listview at a preset refreshing frequency

100621 In the examples of the present disclosure, when the draggable listv iew is not being dragged, the method triggers a thread to refresh the content of the items of the draggable listview; when the draggable listview is being dragged, the method triggers a thread to stop refreshing the content of the items of the draggable listview, then performs the drag operation in the draggable listview, once the dragging operation is finished, triggers a thread to refresh the content of the items of the draggable listview at a preset refreshing frequency. In this way, the content shown in the draggable listview is no longer static and may be refreshed dynamically at a preset refreshing frequency, therefore the method can dynamically display the items of the draggable listview.

100631 Fig. 2 is a flowchart of a preferable example of a method for refreshing the content of a draggable listview of the present disclosure. All steps in Fig. 2 may be performed by processor 2- 10 to execute instructions stored in memory 2- 1 2. Referring to Fig. 2, the method can comprise:

[0064] Step 200(S2Q0), Extracting, by the processor, a value of a flag bit defined in the source code of the drag operation, wherein the flag bit is used for indicating whether the draggable listview is dragged;

100651 Step 210(S210), if the flag bit has a first value, go to Step 250(S25Q), if the flag bit has a second value, go to Step 220(S220);

[0066] If the flag bit has a first value, it indicates the draggable listview is being dragged, if the flag bit has a second value, it indicates the draggable listview isn't being dragged.

[0067] Step 220(S220), determining the type of the data source of the draggable listview's adapter;

[0068] Step 230(S23G), if the data source is local data, identifying, by the processor, a refreshing content relevant to the items of the draggable listview according to a position marker of the local data, and instructing, by the handler provided by the operating system, the main user interface (UI) thread to refresh the content of the items of the draggable listview at the preset refreshing frequency;

[0069] Step 240(S240), if the data source is internet data, instructing, by the processor, by the handler provided by the operating system, the main user interface (UI) thread to refresh the content of the items of the draggable listview with the latest internet data acquired from the internet at the preset refreshing frequency.

[0070] Step 250(S250), performing the drag operation in the draggable listv iew;

[0071] Step 260(S260), determining whether the drag operation is finished; if yes, go to Step 220(S220); if not, go to Step 260(S260).

[0072] In the examples of the present disclosure, the method for refreshing the content of a draggable listview can dynamically refresh the content of the items of the draggable listview at a preset frequency, so as to dynamically display the content of the items of the draggable listv iew.
