上步骤:
1, 添加依赖
添加依赖.png
2,在application中初始化XUtils, 记得在清单文件中写哦
初始化XUtils

还有一个GsonFormat之后的bean都要实现的一个接口
package com.diandou.bigdemo.utils.net;
public interface MResponse {
}
==========================================================
大家还要拿到cancle对象,神马的, 在封装baseActicity或者是BaseFragment在一起cancle掉网络请求, 这样放置奔溃哦
以上的普通的get.post网络请求, 还有文件上传和下载, 还有缓存实现, 大家如果还有需要的, 在去自行封装吧-_-
下面的这个是XUtils封装成的图片加载框架, 目前尚不算完善, 我会根据项目在去进行封装的, 要解决的有listview的view复用不让其混乱, 下拉刷新的时候让图片不要闪, 之后要做到的我在更新上来哦
import android.widget.ImageView;
import org.xutils.image.ImageOptions;
import org.xutils.x;
public class MImageLoaderUtil {
private volatile static MImageLoaderUtil instance;
/**
* Double Check 单例模式
*
* @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();//清楚图片缓存,
}
}
