1、添加依赖：
compile 'org.xutils:xutils:3.3.40'2、自定义application：
/**
* created by joe on 2016/9/25.
*/
public class myapp extends application {
@override
public void oncreate() {
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"4、xutilshttp
private volatile static xutilshttp instance;
private handler handler;
private xutilshttp(){
handler = new handler(looper.getmainlooper());
}
/**
* 单利模式
* @return
*/
public static xutilshttp getinstance(){
if (instance == null){
synchronized (xutilshttp.class){
if (instance == null){
instance = new xutilshttp();
}
}
}
return instance;
}5、写好接口
//接口回调
public interface xcallback{
void onresponse(string result);
void onfail(string result);
}
//下载的接口回调
public interface xdownloadcallback{
void onstart();
void onloading(long total,long current,boolean isdownloading);
void onsuccess(file result);
void onfail(string result);
void onfinished();
}6、 封装普通get请求
/**
* 普通get请求
* @param url
* @param maps
* @param callback
*/
public void get(string url, map<string,string> maps, final xcallback callback){
requestparams params = new requestparams(url);
if (null != maps && !maps.isempty()){
for (map.entry<string,string> entry : maps.entryset()){
params.addquerystringparameter(entry.getkey(),entry.getvalue());
}
}
x.http().get(params, new callback.commoncallback<string>() {
private boolean haserror = false;
private string result = null;
@override
public void onsuccess(string result) {
if (result != null) {
this.result = result;
}
}
@override
public void onerror(throwable ex, boolean isoncallback) {
haserror = true;
toast.maketext(x.app(), ex.getmessage(), toast.length_long).show();
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
if (!haserror && result != null) {
onsuccessresponse(result,callback);
}
}
});
}7、带缓存的get请求
/**
* 带缓存数据的异步get请求
* @param url
* @param maps
* @param ifcache 是否缓存
* @param cachetime 缓存存活时间
* @param callback
*/
public void getcache(string url,map<string,string> maps,final boolean ifcache,long cachetime,final xcallback callback){
requestparams params = new requestparams(url);
params.setcachemaxage(cachetime);
if (null != maps && maps.isempty()){
for (map.entry<string,string> entry : maps.entryset()){
params.addquerystringparameter(entry.getkey(),entry.getvalue());
}
}
x.http().get(params, new callback.cachecallback<string>() {
private boolean haserror = false;
private string result = null;
@override
public boolean oncache(string result) {
if (ifcache && null != result){
this.result = result;
}
// true: 信任缓存数据, 不在发起网络请求; false不信任缓存数据.
return ifcache;
}
@override
public void onsuccess(string result) {
if (result != null) {
this.result = result;
}
}
@override
public void onerror(throwable ex, boolean isoncallback) {
haserror = true;
toast.maketext(x.app(), ex.getmessage(), toast.length_long).show();
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
if (!haserror && result != null) {
onsuccessresponse(result,callback);
}
}
});
}8、普通post请求
/**
* 异步post请求
* @param url
* @param maps
* @param callback
*/
public void post(string url, map<string,string> maps, final xcallback callback){
requestparams params = new requestparams(url);
if (null != maps && !maps.isempty()){
for (map.entry<string,string> entry : maps.entryset()){
params.addbodyparameter(entry.getkey(),entry.getvalue());
}
}
x.http().post(params, new callback.commoncallback<string>() {
private boolean haserror = false;
private string result = null;
@override
public void onsuccess(string result) {
if (result != null) {
this.result = result;
}
}
@override
public void onerror(throwable ex, boolean isoncallback) {
haserror = true;
onfailresponse(ex.getmessage(),callback);
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
if (!haserror && result != null) {
onsuccessresponse(result,callback);
}
}
});
}9、带缓存的post请求
/**
* 带缓存数据的异步post请求
* @param url
* @param maps
* @param ifcache 是否缓存
* @param cachetime 缓存存活时间
* @param callback
*/
public void postcache(string url,map<string,string> maps,final boolean ifcache,long cachetime,final xcallback callback){
requestparams params = new requestparams(url);
params.setcachemaxage(cachetime);
if (null != maps && maps.isempty()){
for (map.entry<string,string> entry : maps.entryset()){
params.addbodyparameter(entry.getkey(),entry.getvalue());
}
}
x.http().get(params, new callback.cachecallback<string>() {
private boolean haserror = false;
private string result = null;
@override
public boolean oncache(string result) {
if (ifcache && null != result){
this.result = result;
}
// true: 信任缓存数据, 不在发起网络请求; false不信任缓存数据.
return ifcache;
}
@override
public void onsuccess(string result) {
if (result != null) {
this.result = result;
}
}
@override
public void onerror(throwable ex, boolean isoncallback) {
haserror = true;
toast.maketext(x.app(), ex.getmessage(), toast.length_long).show();
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
if (!haserror && result != null) {
onsuccessresponse(result,callback);
}
}
});
}10、文件的下载
/**
* 下载文件
* @param url
* @param filepath
* @param callback
*/
public void downfile(string url, string filepath, final xdownloadcallback callback){
requestparams params = new requestparams(url);
params.setsavefilepath(filepath);
params.setautorename(true);
x.http().get(params, new callback.progresscallback<file>() {
@override
public void onsuccess(final file result) {
//下载完成会走该方法
handler.post(new runnable() {
@override
public void run() {
if (callback!=null){
callback.onsuccess(result);
}
}
});
}
@override
public void onerror(final throwable ex, boolean isoncallback) {
handler.post(new runnable() {
@override
public void run() {
if (null != callback){
callback.onfail(ex.getmessage());
}
}
});
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
handler.post(new runnable() {
@override
public void run() {
if (callback!=null){
callback.onfinished();
}
}
});
}
//网络请求之前回调
@override
public void onwaiting() {
}
//网络请求开始的时候回调
@override
public void onstarted() {
handler.post(new runnable() {
@override
public void run() {
if (null != callback){
callback.onstart();
}
}
});
}
//下载的时候不断回调的方法
@override
public void onloading(final long total, final long current, final boolean isdownloading) {
//当前进度和文件总大小
handler.post(new runnable() {
@override
public void run() {
if (callback!=null){
callback.onloading(total,current,isdownloading);
}
}
});
}
});
}11、文件的上传
/**
* 文件上传
*
* @param url
* @param maps
* @param file
* @param callback
*/
public void uploadfile(string url, map<string, string> maps, map<string, file> file, final xcallback callback) {
requestparams params = new requestparams(url);
if (maps != null && !maps.isempty()) {
for (map.entry<string, string> entry : maps.entryset()) {
params.addbodyparameter(entry.getkey(), entry.getvalue());
}
}
if (file != null) {
for (map.entry<string, file> entry : file.entryset()) {
params.addbodyparameter(entry.getkey(), entry.getvalue().getabsolutefile());
}
}
// 有上传文件时使用multipart表单, 否则上传原始文件流.
params.setmultipart(true);
x.http().post(params, new callback.commoncallback<string>() {
@override
public void onsuccess(string result) {
onsuccessresponse(result, callback);
}
@override
public void onerror(throwable ex, boolean isoncallback) {
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
}
});
}12、上传json字符串到服务器
/**
* 上传json串到服务器
* @param url
* @param maps 将需要传的各个参数放在map集合里面
*/
public void uploadjson(string url, map<string, string> maps, final xcallback callback){
jsonobject js_request = new jsonobject();//服务器需要传参的json对象
try {
for (map.entry<string,string> entry : maps.entryset()){
js_request.put(entry.getkey(),entry.getvalue());
}
} catch (jsonexception e) {
e.printstacktrace();
}
requestparams params = new requestparams(url);
params.setasjsoncontent(true);
params.setbodycontent(js_request.tostring());
x.http().post(params, new callback.commoncallback<string>() {//发起传参为json的post请求，
// callback.cachecallback<string>的泛型为后台返回数据的类型，
// 根据实际需求更改
private boolean haserror = false;
private string result = null;
@override
public void onsuccess(string result) {
if (result != null) {
this.result = result;
}
}
@override
public void onerror(throwable ex, boolean isoncallback) {
ex.printstacktrace();
}
@override
public void oncancelled(cancelledexception cex) {
}
@override
public void onfinished() {
if (!haserror && result != null && callback!=null) {
onsuccessresponse(result,callback);
}
}
});
}13、下载调用：
xutilshttp.getinstance().downfile(url, utils.getsdpath() + "/" + "shopbox_guide_video/" + utils.getfilename(url), new xutilshttp.xdownloadcallback() {
@override
public void onstart() {
showdialog(dialog_download_progress);
}
@override
public void onloading(long total, long current, boolean isdownloading) {
//当前进度和文件总大小
mprogressdialog.setmax((int) total);
mprogressdialog.setprogress((int) current);
}
@override
public void onsuccess(file result) {
//下载完成会走该方法
playmedia(result.getpath());
}
@override
public void onfail(string result) {
toast.maketext(mainactivity.this, result, toast.length_short).show();
}
@override
public void onfinished() {
dismissdialog(dialog_download_progress);
}
});14、带缓存get请求
xutilshttp.getinstance().postcache(url, null, true, 60000, new xutilshttp.xcallback() {
@override
public void onresponse(string result) {
// 成功获取数据
}
@override
public void onfail(string result) {
toast.maketext(mainactivity.this, result, toast.length_short).show();
}
});简单简易封装！！！！
