上步驟:
1, 添加依賴

2,在application中初始化XUtils, 記得在清單文件中寫哦
初始化XUtils

還有一個(gè)GsonFormat之后的bean都要實(shí)現(xiàn)的一個(gè)接口
package com.diandou.bigdemo.utils.net;
public interface MResponse {
}
==========================================================
大家還要拿到cancle對(duì)象,神馬的, 在封裝baseActicity或者是BaseFragment在一起cancle掉網(wǎng)絡(luò)請(qǐng)求, 這樣放置奔潰哦
以上的普通的get.post網(wǎng)絡(luò)請(qǐng)求, 還有文件上傳和下載, 還有緩存實(shí)現(xiàn), 大家如果還有需要的, 在去自行封裝吧-_-
下面的這個(gè)是XUtils封裝成的圖片加載框架, 目前尚不算完善, 我會(huì)根據(jù)項(xiàng)目在去進(jìn)行封裝的, 要解決的有l(wèi)istview的view復(fù)用不讓其混亂, 下拉刷新的時(shí)候讓圖片不要閃, 之后要做到的我在更新上來(lái)哦
import android.widget.ImageView;
import org.xutils.image.ImageOptions;
import org.xutils.x;
public class MImageLoaderUtil {
private volatile static MImageLoaderUtil instance;
/**
* Double Check 單例模式
*
* @return
*/
public static MImageLoaderUtil getInstance() {
if (instance == null) {
synchronized (MImageLoaderUtil.class) {
if (instance == null) {
instance = new MImageLoaderUtil();
}
}
}
return instance;
}
public static void load(ImageView imageView, String url) {
ImageOptions options = new ImageOptions.Builder().setAutoRotate(true)
.setRadius(20)
.setFadeIn(true)
.setAutoRotate(true)
.setImageScaleType(ImageView.ScaleType.CENTER_CROP)
.setUseMemCache(true).build();
x.image().bind(imageView, url, options);
//x.image().clearCacheFiles();//清楚圖片緩存,
}
}
