In another specific embodiment of the invention, a kind of mobile terminal application program EMS memory occupation optimization method, the step
Anti- Rendering operations include in rapid 2：The elimination of format information is carried out to the word in unit and/or picture in unit is carried out minimum
Change is handled.
In another specific embodiment of the invention, a kind of mobile terminal application program EMS memory occupation optimization method, the shifting
Moved end application program EMS memory occupation optimization method is realized based on React-Native frame structures.
In another specific embodiment of the invention, a kind of mobile terminal application program EMS memory occupation optimization method.The reality
Apply a method as follows in detail：
cell：The part of list, is a unit of list.
In the prior art, as described in Figure 2, during list upward sliding, the cell 1 of top has been ejected screen
Curtain foreign side, bottommost will create a new cell 5.
Although this cell 1 in Fig. 2 is not shown above in screen, still it is present among APP internal memory,
If the ratio slided is very fast, system can ceaselessly create more new cell, and cell 1, cell 2 ... will be present in
Among internal memory, then internal memory will explode.Want to solve this problem, it is necessary to which the cell outside to screen does some processing, allows him
Occupy the internal memory of minimum.
A kind of mobile terminal application program EMS memory occupation optimization method that this specific embodiment is provided, comprises the following steps：
1st, before during cell is rendered, system does not do any operation, that is to say, that each in list
Cell, has farthest been rendered out, it is now desired to first judged before rendering, if can render.
In above-mentioned steps, by defining a Boolean type variable visible, distinguish whether cell needs by the variable
Minimize.
2nd, in order to most accurately control variable visible value, visible value is carried out on most suitable opportunity
Change, it is necessary to be achieved the goal by some calculating.
(1) in order in sliding process, that time point that can accurately catch cell to disappear and will appear from,
Need constantly to go to take cell position.Here it is possible to realize onscroll methods when list initialization：
<ListView onScroll={ this.onScrollDrag }/>
Then inside onScrollDrag methods, it can be taken by e.nativeEvent.contentOffset.y
The offset of offset, as list relative to screen.Offset is subtracted with y values of the current cell in the coordinate system of list,
It can be obtained by height of the cell apart from the top of screen.
, so, can by monitoring onScroll methods, as long as finger has slided screen, it is possible to listen to this event
To be will appear from in a flash draw out him in cell, he can also be minimized in a flash what cell disappeared.So
It just can farthest complete the optimization of internal memory.
(2) value is recorded with a floating number distance.
When distance is less than or equal to 0, representing cell will frame out, and be rolled to above screen, now,
Visible is now arranged to false；
When distance is more than or equal to the height of screen, representing cell will frame out, and be rolled to screen
Lower section, is now arranged to false by visible；
When distance is within 0 to screen height this interval range, visible is arranged to true.
By the algorithm, it is that outside screen, which cell is in screen that can easily judge which cell
Portion.
3rd, need to carry out cell some processing now, the internal memory of minimum is occupied when allowing him outside screen, because
Now user can't see the cell, so, he can be minimized, be degenerated to a most basic control.
Because user can't see the content outside screen, user will not be concerned about that what the content of outside is, so
The element outside screen is directed to, allows him to become minimum element, the internal memory of minimum is occupied, does not spend and render those pictures, text
The thing of word etc.In app, image (picture) component is most consumption internal memory, and the internal memory shared by him is a common sky
When the picture of more than ten times of white view, particularly some comparison high definitions.
4th, can be cell's in order to which the cell by outside screen as fast as possible is degenerated to a basic view
When visible states one change, it is rendered again.
First, visible is put into state machine, can thus listens to the event that visible value changes, as long as
Visible mono- changes, and cell will be rendered again.So, it is necessary to first judge visible value when cell is rendered, then
Rendered：
(1) if visible is true, it is in inside screen, it is necessary to normally render him to represent him, allows user to have seen
Whole cell
(2) if visible is false, it is that outside screen, now, cell only need to be set to wide height once to represent him,
Any other operation is not done.That is, him as a most basic view.
Visible is put into state machine, can be refreshed in cell convenient very first time when visible value is changed
Hold, by the cell outside screen to minimum.State machine is the container that React-Native is supplied to developer, is put into state
The thing of machine, will render view again as long as attribute changes.
The technical scheme of this specific embodiment, allows list to take less internal memory as far as possible, is particularly showing a large amount of
When data.Facebook provides good component listview to show list, but is not provided with good side
The problem of method is to solve internal memory optimization, and most consume the part of internal memory, is exactly often those picture components and character component, with
The place that family be can't see, without picture, word these things are showed, it is only necessary to they are rendered on suitable opportunity
Come.By above method, the performance of list can be allowed greatly to be lifted, allow app to take less internal memory during use.
