Abstract
The present invention relates to a kind of Assets files in batch copy methods, it passes through the path of file under the pre-configured Assets catalogues of resource.xml configuration files, and read resource.xml files using AssetsManager.open interfaces, the path of file destination is obtained, then AssetsManager.open interfaces is called to read file destination.Compared with prior art, batch copy method of the invention substantially increases the speed of batch copy.
Description
Technical field
The present invention relates to Android applied technical fields, and in particular to a kind of Assets files in batch copy method.
Background technology
Assets puts the catalogue of resource file for Android application memories.AssetsManager is in Android
One resource management class that can operate Assets catalogues, it contains the interfaces such as list and open, and list interfaces can obtain
Folder path under Assets catalogues, open interfaces can open the file specified under Assets catalogues.Sdcard is
Android phone stored memory card.
As shown in Figure 1, needing to copy the All Files under assets/config catalogues under sdcard to, existing solution
Certainly scheme is All Files folder and the text traversed by AssetsManager.list (" config ") interface under config catalogues
Part calls AssetsManager.open to read file and is copied if get is file to traversal；If got
It is file, then then needing that list interfaces is called to carry out traversal acquisition again, needs to call AssetsManager.list
(" config/data ") and AssetsManager.list (" config/resource "), if there is folder hierarchy
The numbers for calling list much more.
Currently existing scheme traverses file by calling AssetsManager.list interfaces, and interface calling compares
It takes, averagely takes at 20 milliseconds ~ 200 milliseconds, had differences according to loom performance difference.So existing scheme there are the shortcomings that
Be exactly if there is folder hierarchy it is more in the case of, need repeatedly to call AssetsManager.list interfaces, cause non-
It often takes, even ANR, ANR can occur for improper use（Application Not Responding）Refer to application program without
Response, if cannot respond user operation case in Android applications 5s will occur ANR.
Invention content
The purpose of the present invention is to provide a kind of Assets files in batch copy methods, can improve Android applications
Copy the speed of sdcard to from Assets files in batch.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of Assets files in batch copy method comprising following steps：
Step 1 creates resouces.xml configuration files under Assets catalogues, and the content of this document is under Assets catalogues
File path configuration, partial content is as shown in Figure 3；
Step 2 calls AssetsManager.open (" resources.xml ") to read resource.xml configuration files, and
Resources.xml files are parsed, the file path under Assets catalogues, i.e. file destination path are obtained；
Step 3, according to the file destination path obtained in step 2, call AssetsManager.open to read file destination, and
File destination is copied in sdcard.
After adopting the above scheme, the present invention by the pre-configured Assets catalogues of resource.xml configuration files hereafter
The path of part, and resource.xml files are read using AssetsManager.open interfaces, the path of file destination is obtained,
Then AssetsManager.open interfaces are called to read file destination.Under identical file and quantity of documents, existing skill
The copy method of art averagely takes in second grade level, reaches on the type of part tens seconds, and uses the method for the present invention in phase
Reach Millisecond under same type, substantially increases the speed of batch copy.Moreover, the batch copy method of the present invention only needs
Safeguard resources.xml configuration files, and automatic script can be used to generate for this document, maintenance cost is low.
Description of the drawings
Fig. 1 is Assets catalogues schematic diagram of the present invention；
Fig. 2 is flow chart of the present invention；
Fig. 3 is the content schematic diagram of resources.xml files of the present invention.
Specific embodiment
As shown in Fig. 2, present invention is disclosed a kind of Assets files in batch copy method, it is specific as follows：
Step 1 creates resouces.xml configuration files under Assets catalogues, and the content of this document is under Assets catalogues
File path configuration, partial content is as shown in Figure 3；
Step 2 calls AssetsManager.open (" resources.xml ") to read resource.xml configuration files, and
Resources.xml files are parsed, the file path under Assets catalogues, i.e. file destination path are obtained；
Step 3, according to the file destination path obtained in step 2, call AssetsManager.open to read file destination, and
File destination is copied in sdcard.
The present invention it is critical that the present invention passes through under the pre-configured Assets catalogues of resource.xml configuration files
The path of file obtains file destination path without using AssetsManager.list interfaces, but uses
AssetsManager.open interfaces read resource.xml files, obtain the path of file destination, then directly invoke
AssetsManager.open interfaces read file destination.Under identical file and quantity of documents, the copy of the prior art
Method averagely takes in second grade level, reaches on the type of part tens seconds, and uses the method for the present invention in identical type
Under reached Millisecond, substantially increase batch copy speed.Moreover, the batch copy method of the present invention only needs to safeguard
Resources.xml configuration files, and automatic script can be used to generate for this document, maintenance cost is low.
The above is only the embodiment of the present invention, is not intended to limit the scope of the present invention, therefore every
According to the technical essence of the invention to any subtle modifications, equivalent variations and modifications made by above example, this is still fallen within
In the range of inventive technique scheme.
Claims (1)
1. a kind of Assets files in batch copy method, it is characterised in that：The batch copy method includes the following steps：
