Xutils3网络请求的封装

Xutils3网络请求的封装1.gradle中添加compile'org.xutils:xutils:3.3.40'112.自定义Application/***CreatedbyJoeon2016/9/25.*/publicclassMyAppextendsApplication{@OverridepublicvoidonCreate(){super.onCreate();x.Ext.init(this);x.Ext.setDebug(BuildConfig.DEBUG);//是否输出debug日志,开启debug会影响性能.}}3.清单文件application节点点添加android:name=".activitys.MyApp"上面三步走完接下来就可以使用了先写一个单利类，话不多说上代码privatevolatilestaticXutilsHttpinstance;privateHandlerhandler;privateXutilsHttp(){handler=newHandler(Looper.getMainLooper());}/***单利模式*@return*/publicstaticXutilsHttpgetInstance(){if(instance==null){synchronized(XutilsHttp.class){

if(instance==null){instance=newXutilsHttp();}}}returninstance;}写好接口//接口回调publicinterfaceXCallBack{voidonResponse(Stringresult);voidonFail(Stringresult);}//下载的接口回调publicinterfaceXDownLoadCallBack{voidonstart();voidonLoading(longtotal,longcurrent,booleanisDownloading);voidonSuccess(Fileresult);voidonFail(Stringresult);voidonFinished();}封装普通get请求/***普通get请求*@paramurl*@parammaps*@paramcallback*/publicvoidget(Stringurl,Map<String,String>maps,finalXCallBackcallback){RequestParamsparams=newRequestParams(url);if(null!=maps&&!maps.isEmpty()){for(Map.Entry<String,String>entry:maps.entrySet()){params.addQueryStringParameter(entry.getKey(),entry.getValue());}}x.http().get(params,newCallback.CommonCallback<String>(){privatebooleanhasError=false;privateStringresult=null;@OverridepublicvoidonSuccess(Stringresult){
