As an example, the sub-view type node data structure shown in fig. 2 is a schematic design diagram, where the structure has a linked list node property and is used for bearing relationship attribute preset of sub-view types, and the sub-view node may be encapsulated through a view node (view node) data structure shown in fig. 2, for example: advertisement view node (AdViewnode), system notification view node (Notifynode) and user recommended content view node (CommonViewnode), wherein each view node comprises the view type, the number of nodes corresponding to the view type and the weight of the entire list view occupied by the view type.
For example, as shown in fig. 3, a first linked list may be determined according to the child view type node data structure shown in fig. 2, where the first linked list is a permutation chain of view types included in the list view.

In this way, the multi-type sub-view content data source is stored and defined in a mode of combining the linked list and the array, the second target node corresponding to the first target node can be directly obtained from the second linked list which is preset according to the first target node, the content data corresponding to the target sub-view can be obtained from the second target node, the content data corresponding to the sub-view can be directly changed in the second, the maintenance of the list view and the investigation of the problem of the list view are facilitated, the multi-type data source is compatible with a single adapter, the content data corresponding to the sub-view in the list view can be obtained from the same data source, the problem of logic complexity confusion of invoking the sub-view data by the list view can be solved, the efficiency of view data acquisition, management and maintenance can be improved, and the expansibility of the multi-type content data is improved.
In one implementation manner, after the obtaining the content data corresponding to the target sub-view from the second target node, the method further includes:
and returning the content data corresponding to the target sub-view to the list view.
Specifically, the content data corresponding to the target sub-view is returned to the list view, and the content data corresponding to the target sub-view can be displayed in the list view.
In one implementation manner, as shown in fig. 6, each first node stores in advance a view type corresponding to the first node, each first node corresponds to only one view type, and different first nodes correspond to different view types, and according to the first target node, a second target node corresponding to the first target node is obtained from a second preset linked list, and content data corresponding to the target sub-view is obtained from the second target node, including the following steps:
step 602: and determining a target view type and second position information corresponding to the target sub-view according to the first target node.
And acquiring the child view type of the designated position from the first linked list through the adapter, triggering the linked list to start recursive calculation from the root node, and returning the view type and the second position information of the target child view in the array data source in the corresponding node in the second linked list when the view type is matched with the corresponding view type.
Wherein the second position information is an order of arrangement of the target sub-views in the first target node.
As an example, as shown in fig. 4, for example, the first linked list is an arrangement order list of sub-view types included in the list view, where the first linked list includes visible nodes and/or invisible nodes, the visible nodes are first nodes, and the first target nodes corresponding to the target sub-views in the first linked list may be searched through the adapter, and the target view types and the second position information corresponding to the target sub-views may be determined from the root node of the first linked list through the following steps.
1) And judging whether the current node is empty or not.
2) If the current node is empty, the returned second position information is empty, and if the current node is not empty, whether the current node is visible or not is judged, namely whether the current node is the first node or not is judged.
3) If the current node is not visible, the current node is the next node in the first linked list, and the step 1) is executed in a return mode, if the current node is visible, namely, the current node is the first node, the number of sub views corresponding to the current node is obtained, and the size between the first position information and the number of sub views corresponding to the current node is compared.
4) If the first position information is smaller than the number of sub-views corresponding to the current node, the current node is a first target node corresponding to the target sub-view, the view type corresponding to the current node is the target view type, the first position information at the moment is the second position information, the target view type and the second position information are returned, if the first position information is larger than the number of sub-views corresponding to the current node, the first position information is converted into a value of subtracting the number of sub-views corresponding to the current node from the first position information, the current node is the next node in the first linked list, and the step 1) is executed in a returning mode.
Step 604: and acquiring the second target node from the second linked list according to the target view type.
Each second node in the second linked list stores the view type corresponding to the second node in advance, each second node only corresponds to one view type, and different second nodes correspond to different view types.
Specifically, the second linked list is directly traversed, and the second target node is obtained from the second linked list according to the type of the target view.

The arrangement order of the target sub-views in the first target node and the second target node is the same, and the second target node stores content data of sub-views with target number in advance, wherein the target number is the number of sub-views corresponding to the first target node.
Specifically, in the second linked list, content data corresponding to sub-views of the same view type are stored in the same node in the form of an array, and after the second target node is determined, the content data corresponding to the second position information is directly searched in the content data array corresponding to the sub-views in the second node according to the second position information.
In this way, the target view type and the second position information corresponding to the target sub-view are determined according to the first target node, the second target node is acquired from the second linked list according to the target view type, and the content data corresponding to the target sub-view is acquired from the second target node according to the second position information, so that the content data of sub-views with different view types can be acquired in one data source linked list, the problem that when the view types are increased, the logic of invoking the sub-view data by the list view is complex and disordered can be solved, and the efficiency of acquiring, managing and maintaining the view data can be improved.
In one implementation, the method further comprises:
when the list view is loaded or updated for the first time, according to a preset rule, determining the visibility of each third node, the visibility of the view type corresponding to each third node and the visibility of the sub-view corresponding to each third node according to attribute information of the view type corresponding to each third node in a third linked list, wherein nodes corresponding to each third node are arranged in the first linked list, the visibility of the nodes in the first linked list is the same as the visibility of the corresponding third nodes, and the attribute information comprises the weight of the view type corresponding to each third node in the list view.
For example, as shown in fig. 7, a third linked list may be determined according to the child view type node data structure shown in fig. 2, where the third linked list is a weighted sequential chain of view types included in the list view.
Specifically, when the list view is initially loaded or updated, the initialization may be performed through the adapter or the observer monitoring may be triggered, and as an example, as shown in fig. 8, when the list view is initially loaded or updated, starting from the root node of the third linked list, the preset rule may be customized according to the requirement, and expanding the preset rule, for example: the method comprises the steps of determining the visibility of each third node according to the attribute information of the view type corresponding to each third node in a third linked list, wherein the visibility comprises the following steps of:
1) Judging whether the current third node is empty or not, if so, ending the flow, and if not, judging whether the current third node accords with rules preset by all types of nodes of the list view, for example, the weight value occupied by the current third node is smaller than or equal to the residual weight value;
2) If the current third node is judged not to accord with the preset rule of each type of node of the list view, the current third node is set as an invisible node, namely the visibility of the view type corresponding to the current third node is set as invisible, the visibility of the sub view corresponding to the current third node is invisible, the residual weight value is obtained by converting the current state into the residual weight value and subtracting the weight value of the current third node, the current third node is the next third node in the third linked list, and the step 1) is executed in a return manner; if the current third node accords with the preset rule of each type of node of the list view, the current third node is set as a visible node, namely the visibility of the view type corresponding to the current third node is set as visible, the visibility of the sub view corresponding to the current third node is set as visible, the residual weight value is obtained by subtracting the weight value of the current third node from the current residual weight value, the current third node is the next third node in the third linked list, and the step 1 is executed in a return mode.
In this way, the visibility of each sub-view can be set directly through a third linked list through the preset rule, so that the setting logic is simple and effective, the maintenance efficiency and the management efficiency of the view list are improved, and the calling of the content data of the sub-view corresponding to the list view is facilitated.
In one implementation, the method further comprises:
receiving request information which is sent by the list view and used for obtaining the number of the visible sub-views; responding to the request information, and counting the total number of sub-views corresponding to the first node in the first linked list; and sending the total number of sub-views corresponding to the first node in the first linked list to the list view.
Specifically, as one, for example, as shown in fig. 9, from the root node of the first linked list, counting the total number of sub-views corresponding to the view types with visible visibility in the first linked list, that is, the total number of sub-views corresponding to the first node, includes the following steps:
1) And judging whether the current node is empty, if so, returning the total number of the visible child views, and if not, judging whether the current node is visible.
2) If the current node is visible, the number of sub-views of the current node is obtained, the total number of visible sub-views is converted into the total number of visible sub-views plus the number of sub-views of the current node, the current node is converted into the next node in the first linked list, and the step 1) is executed in a return mode, and if the current node is not visible, the current node is converted into the next node in the first linked list, and the step 1) is executed in a return mode.
Thus, the request information for acquiring the number of the visible sub-views is sent by receiving the list view; responding to the request information, and counting the total number of sub-views corresponding to the first node in the first linked list; the total number of the sub-views corresponding to the first node in the first linked list is sent to the list view, so that the number of the sub-views can be seen, and the maintenance and management of the subsequent corresponding list view are facilitated.
