Android's hottest rapid development framework Xutils

recently searched some framework for beginners to learn, compared a bit xutils is currently more active on Git a framework, is based on the development of afinal, more than afinal stability improved a lot, the following is the introduction: Xutils Introduction

• Xutils contains a lot of useful Android tools.
• Originally derived from the Afinal framework, Xutils has been heavily refactored to allow the xutils to support large file uploads, more comprehensive HTTP request protocol support (10 predicates), more flexible ORM, more event annotations support, and no confusion effects ... Generally speaking, Android development, the basic confusion is possible, but in addition to confusion, but also need to use some resource platform to add a layer of security to the previously confused code, that is, encryption protection, which is now doing Android development has to learn not to know a skill!
• XUITLS Minimum compatible Android 2.2 (API Level 8)

• current Xuti LS has four main modules:

• • DbU TILs module:

    • android in Orm frame , a line of code can be used for additional deletions;
    • support transactions, closed by default;
    • Support for binding foreign keys, saving entities when the foreign key associated entities are automatically saved or updated;
    • auto-load foreign key associated entities, support delay loading;
    • support chain expression query, more intuitive query semantics, refer to the following introduction or sample examples.
  • viewutils module:

    • android ioc frame, UI, resource, and event bindings can be fully annotated,
    • new event binding, which works when confused with obfuscation tools ;
    • currently supports 20 commonly used event bindings, Viewcommoneventlistener class and package com.lidroid.xutils.view.annotation.event.

  • httputils module:

    • supports synchronous, asynchronous requests;
    • support large file upload, upload large files will not oom;
    • support Get,post, Put,move,copy,delete,head,options,trace,connect request;
    • download support 301/302 Redirect, support setting whether to rename downloaded files according to content-disposition;
    • The request to return text content (by default, only get requests enabled) supports caching, setting the default expiration time and the expiration time for the current request.

  • Bitmaputils module:

    • When loading the bitmap, there is no need to consider the phenomenon of the image dislocation when the Oom and the Android container move quickly during the bitmap loading process.
    • Support to load network pictures and local images;
    • The memory management uses the LRU algorithm, better manages the bitmap memory;
    • Configurable line preempted thread count, cache size, cache path, load display animation, etc...
  The following permissions are required to use the Xutils rapid development Framework :
• 
  Things to note when confusing:
• 
  
• • Add Android Default obfuscation configuration ${sdk.dir}/tools/proguard/proguard-android.txt
  • Do not confuse the annotation type in xutils, add confusion Configuration:-keep class * extends Java.lang.annotation.Annotation {*;}
  • Do not confuse entity classes that use Dbutils module persistence, or annotate all table and column names @table (name= "xxx"), @Id (column= "xxx"), @Column (column= "xxx"), @Foreign (column= "XXX", foreign= "xxx");

  Dbutils How to use:

• Dbutils db = Dbutils.create (this); User user = new user (); It is important to note that the user object must have an id attribute, or a property User.setemail ("[email protected]") with the @id annotation, user.setname ("Wyouflf");d B.save ( user); When you save an entity with Savebindingid, you assign a value to the ID of the entity ...//find the Parent entity = Db.findbyid (Parent.class, Parent.getid ()); list<parent> list = Db.findall (Parent.class);//Find parent parent = Db.findfirst by Type (Selector.from (Parent.class). Where ("name", "=", "Test")),//is nullparent Parent = Db.findfirst (Selector.from (Parent.class). WHERE ("name", "=", null) );//is not nullparent Parent = Db.findfirst (Selector.from (Parent.class). WHERE ("name", "! =", null));//Where id<54 and (age>20 OR age<30)                                   ORDER by ID LIMIT pageSize OFFSET pageoffsetlist<parent> list = Db.findall (Selector.from (Parent.class) . WHERE ("id", "<", si). and (Wherebuilder.b ("Age", ">",). or ( "Age", "<", ()). ("id").Limit (pageSize). Offset (pageSize * pageIndex));//OP is "in", the last parameter must be an array or an implementation class of iterable (for example, Li St, etc.) Parent test = Db.findfirst (Selector.from (Parent.class). WHERE ("id", "in", New Int[]{1, 2, 3});//OP is "between", The last parameter must be an array or Iterable implementation class (such as list, etc.), Parent test = Db.findfirst (Selector.from (Parent.class). WHERE ("id", "between", new string[]{"1", "5"}));D Bmodel Dbmodel = Db.finddbmodelall (Selector.from (Parent.class). Select ("name"));//select (" Name ") only remove the name column list<dbmodel> dbmodels = Db.finddbmodelall (Selector.from (Parent.class). GroupBy (" name "). Select ("Name", "Count (name)"); ... list<dbmodel> dbmodels = db.finddbmodelall (sql); Custom SQL query Db.execnonquery (SQL)//execute custom SQL ...

  
  viewutils How to use
  • UI binding and event binding can be done in a fully annotated manner.
  • No need for Findviewbyid and Setclicklistener.

  • Xutils's view annotation requires that an ID be provided so that code confusion is not affected. @ViewInject (R.id.textview) TextView textview;//@ViewInject (Vale=r.id.textview, Parentid=r.id.parentview)// TextView TextView; @ResInject (id = r.string.label, type = restype.string) private string label;//cancels the way the event was bound by using the method name. Using ID binding is not affected by obfuscation//support binding multiple IDs @OnClick ({r.id.id1, R.id.id2, R.ID.ID3})//or @OnClick (VALUE={R.ID.ID1, R.id.id2, R.ID.ID3}, PARENTID={R.ID.PID1, R.id.pid2, R.ID.PID3})// See Viewcommoneventlistener classes and Package com.lidroid.xutils.view.annotation.event for more event support. @OnClick (R.id.test_button) public void Testbuttonclick (View v) {//method signature must match the requirements in the interface ...}    ...//injected in activity: @Overridepublic void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);    Setcontentview (R.layout.main); Viewutils.inject (this);    Inject view and events ... textview.settext ("some text ..."); ...} Injected in fragment: @Overridepublic View Oncreateview (layoutinflater inflater, ViewGroup container, Bundle Savedinstancestate) {View view = Inflater.inflate (r.layout.bitmap_fragmENT, container, false); Load Fragment layout Viewutils.inject (this, view); Inject view and events ...} Injected in preferencefragment: public void onactivitycreated (Bundle savedinstancestate) {super.onactivitycreated (    Savedinstancestate); Viewutils.inject (this, Getpreferencescreen ()); Inject view and events ...} Other overloads//inject (view view),//inject (activity activity)//inject (preferenceactivity preferenceactivity)//inject ( Object handler, view view)//Inject (object handler, activity activity)//Inject (object handler, Preferencegroup Preferenc Egroup)//inject (Object handler, preferenceactivity preferenceactivity)

    
    
  httputils How to use: normal Get Method

• Httputils http = new Httputils (); Http.send (HttpRequest.HttpMethod.GET,    "http://www.lidroid.com",    New Requestcallback<string> () {        @Override public        void onloading (Long, Long, Boolean isuploading) {            Testtextview.settext (current + "/" + total);        }        @Override public        void onsuccess (responseinfo<string> responseinfo) {            Textview.settext ( Responseinfo.result);        }        @Override public        void OnStart () {        }        @Override        the public void OnFailure (httpexception error, String msg) {        }});

  
  Uploading files using Httputils or submitting data to the server (POST method)

• Requestparams params = new Requestparams ();p arams.addheader ("name", "value");p arams.addquerystringparameter ("name", "Value");//The default use of bodyparamsentity,//is similar to urlencodedformentity ("application/x-www-form-urlencoded") when it contains only string arguments. Params.addbodyparameter ("name", "value"), or//Multipartentity ("Multipart/form-data") is used by default after adding the file parameter,//if required "multipart/ Related ", the Multipartentity support settings provided in Xutils are subtype to" related ". Use Params.setbodyentity (httpentity) to set more types of httpentity (such as://Multipartentity,bodyparamsentity,fileuploadentity, inputstreamuploadentity,stringentity). For example, send JSON parameter: params.setbodyentity (new Stringentity (Jsonstr,charset));p arams.addbodyparameter ("File", New file (" Path ")); Httputils http = new Httputils (); Http.send (HttpRequest.HttpMethod.POST, "Uploadurl ...", params, new REQUESTCALLB        Ack<string> () {@Override public void OnStart () {testtextview.settext ("conn ..."); } @Override public void onloading (long, Long, Boolean isuploading) {           if (isuploading) {testtextview.settext ("Upload:" + current + "/" + total);            } else {Testtextview.settext ("Reply:" + current + "/" + total); }} @Override public void onsuccess (responseinfo<string> responseinfo) {Testtextvie        W.settext ("Reply:" + Responseinfo.result); } @Override public void OnFailure (httpexception error, String msg) {Testtextview.settext (error.g        Etexceptioncode () + ":" + msg); }});

  
  To download a file using httputils:
  • Support breakpoint continuation, stop downloading task at any time, start task

  • httputils http = new Httputils (); HttpHandler handler = http.download ("http://apache.dataguru.cn/httpcomponents/httpclient/source/ Httpcomponents-client-4.2.5-src.zip ","/sdcard/httpcomponents-client-4.2.5-src.zip ", true,//If the destination file exists, Then the unfinished section continues to download.    The server does not support range when it is newly downloaded.    True,//If the file name is obtained from the request return information, it is automatically renamed after the download is complete. New Requestcallback<file> () {@Override public void OnStart () {testtextview.settext ("conn.        ..");        } @Override public void onloading (long, Long, Boolean isuploading) {Testtextview.settext (CU        Rrent + "/" + total); } @Override public void onsuccess (responseinfo<file> responseinfo) {Testtextview.settext ("        Downloaded: "+ responseInfo.result.getPath ());        } @Override public void OnFailure (httpexception error, String msg) {testtextview.settext (msg); }});//Call the Cancel () method to stop downloading Handler.cancel (); 

    
    
  bitmaputils How to use

• Bitmaputils bitmaputils = new Bitmaputils (this);//load Network picture Bitmaputils.display (Testimageview, "http://bbs.lidroid.com/ Static/image/common/logo.png ");//load local picture (path with/start, absolute path) Bitmaputils.display (Testimageview,"/sdcard/test.jpg ");// Load the picture in assets (the path starts with assets) Bitmaputils.display (Testimageview, "assets/img/wallpaper.jpg");// When you use a container such as a ListView to display a picture, the Pauseonscrolllistener controls the slide and pauses loading of the picture during the Quick slide Listview.setonscrolllistener (new Pauseonscrolllistener (Bitmaputils, False, True)); Listview.setonscrolllistener (New Pauseonscrolllistener ( Bitmaputils, False, True, Customlistener));

  
  Output Log Logutils

• Add tag automatically, format: Classname.methodname (l:linenumber)//can set global Logutils.allowd = False,logutils.allowi = False ..., Controls whether to output log. Custom log Output Logutils.customlogger = new Xxxlogger (); LOGUTILS.D ("Wyouflf");
