In order to technical solutions according to the invention are described, illustrate below by specific embodiment.
Embodiment one:
Fig. 1 illustrates the flow chart of a kind of focus control method based on android control that first embodiment of the invention provides, and details are as follows:
Step S11, when user enters interface, loads and shows the fragment control of ground floor in described interface；Each control is corresponding with a control id (i.e. identifier).
Wherein, user enters interface and is the main interface entering the activity software realized.
In this step, the ground floor of system loads activity, and in the ground floor loaded, add the fragment control of this ground floor, when adding control to each layer, can be added by dynamic mode, it is possible to added by static mode.Wherein, dynamic addition manner refers to that the program according to presetting is added one by one, namely shows the fragment control of interpolation one by one；And the addition manner of static state refers to the mode according to xml layout, after being loaded by whole fragment controls, another rising shows.The ground floor of the activity of system loads is the level defined first, and after this ground floor, the level of definition is the second layer, other the like.Wherein, all corresponding level of each layer of activity uniquely identifies, in order to distinguish different layers.Described activity includes least one layer of fragment control, and each layer includes at least one fragment control.Assume that activity has N shell, the fragment control of ground floor is Fragment_1, and the fragment control of the second layer is Fragment_2, and the fragment control of third layer is Fragment_3, ... the fragment space of n-th layer is Fragment_N, then the layout of activity is as shown in Figure 2.In embodiments of the present invention, relation between the fragment control of adjacent two layers is not filiation, the simply quantitative relation between simple identifier, once enter into the fragment control of lower floor, just it doesn't matter with a upper fragment control, and in existing method, the relation between the fragment control of adjacent two layers is filiation, and it must one-level one-level upwards be looked for.
Alternatively, in described loading and when showing the fragment control of ground floor in described interface, including:
Initialization level variable, and focus is arranged on the fragment control of display, described level variable is for identifying the level residing for fragment control of display.This level variable defines in advance in activity, specifically, when loading and show the fragment control of ground floor in described activity, it is 1 by level initialization of variable,, focus is arranged in the fragment control of ground floor, so that user knows the position of the fragment control of display according to the focus arranged meanwhile, during default initialization, focus is arranged in first fragment control of ground floor.Correspondingly, when focus is in the second layer, this level variable becomes 2, other the like.
