Xutils Introduction

• Xutils contains a lot of useful Android tools.
• Xutils from the afinal framework, the afinal has been heavily reconstructed, allowing the xutils to support large file uploads, more comprehensive HTTP request protocol support, more flexible ORM, more event annotations support, and no confusion affected ...
• XUITLS Minimum compatible Android 2.2 (API Level 8)

Currently Xutils has four main modules:

• Dbutils module:

  • The ORM framework in Android, a line of code can be used for the enhancement and deletion;
  • Support transactions, closed by default;
  • Annotations can be used to customize table names, column names, foreign keys, uniqueness constraints, NOT NULL constraints, check constraints, etc. (Please note the table and column names when confusion is required);
  • Support for binding foreign keys, saving entities when the foreign key associated entities are automatically saved or updated;
  • Automatic loading of 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:

  • The IOC framework in Android enables UI binding and event binding in a fully annotated manner;
  • New event binding mode, the use of obfuscation tools can still work properly;
  • Currently supports 11 commonly used event bindings, see Viewcommoneventlistener Class and package com.lidroid.xutils.view.annotation.event.

• Httputils module:

  • Support synchronous, asynchronous requests;
  • Support large file upload, upload large files will not oom;
  • Support Get,post,put,move,copy,delete,head request;
  • Download support 301/302 Redirect, support setting whether to rename downloaded files according to Content-disposition;
  • A GET request that returns text content supports caching, which sets 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:

• 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:

Viewutils How to use

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

Httputils How to use: Normal Get method

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

Requestparams params = new Requestparams (); Params.addheader ("name", "value"); Params.addquerystringparameter ("name", "value"); Bodyparamsentity is used by default when only string parameters are included,//similar to urlencodedformentity ("application/x-www-form-urlencoded"). Params.addbodyparameter ("name", "value"); Multipartentity ("Multipart/form-data") is used by default after adding the file parameters,//If "multipart/related" is required, The Multipartentity support settings provided in Xutils are subtype "related". Use Params.setbodyentity (httpentity) to set more types of httpentity such as://Multipartentity,bodyparamsentity,fileuploadentity, inputstreamuploadentity,stringentity). Params.addbodyparameter ("File", new file ("path")); ... Httputils http = new Httputils (); Http.send (HttpRequest.HttpMethod.POST, "Uploadurl ...", params, new requestcallback<string> () {@Override public void OnStart () {testtextview.settext ("conn ..."); @Override public void onloading (long total, long current) {Testtextview.settext (current + '/' + total);} @Override Publi c void onsuccess (String result) {Testtextview.settext ("Upload response: "+ Result.getpath ());} @Override public void OnFailure (httpexception error, String msg) {Testtextview.settext (Error.getexceptioncode () + ":" + M SG);  } });

To download a file using httputils:

• Support breakpoint continuation, stop downloading task at any time, start task
