RXjava网络获取图片数据的方法

本文实例为大家分享了rxjava网络获取图片数据的具体代码，供大家参考，具体内容如下

rxjava

// an highlighted block
image = findviewbyid(r.id.tu);

  observable.create(new observableonsubscribe<bitmap>() {
   @override
   public void subscribe(observableemitter<bitmap> e) throws exception {
    e.onnext(getbitmap());
   }
  })
    //设置数据在子线程中遍历
    .subscribeon(schedulers.io())
    //设置图片在主线程中加载
    .observeon(androidschedulers.mainthread())
    .subscribe(new observer<bitmap>() {
     @override
     public void onsubscribe(disposable d) {

     }

     @override
     public void onnext(bitmap bitmap) {
      image.setimagebitmap(bitmap);
     }

     @override
     public void onerror(throwable e) {

     }

     @override
     public void oncomplete() {

     }
    });
  image.setonclicklistener(new view.onclicklistener() {
   @override
   public void onclick(view view) {
    toast.maketext(mainactivity.this, "ee", toast.length_short).show();
   }
  });
  image.setonclicklistener(new view.onclicklistener() {
   @override
   public void onclick(view view) {

   }
  });

网络获取数据

// an highlighted block
//获取网络数据
 private bitmap getbitmap() {
  string str = "https://b-ssl.duitang.com/uploads/blog/201406/16/20140616171020_tiexr.thumb.700_0.jpeg";
  try {
   url url = new url(str);
   httpurlconnection urlconnection = (httpurlconnection) url.openconnection();
   urlconnection.setrequestmethod("get");
   urlconnection.setconnecttimeout(2000);
   urlconnection.connect();
   if(urlconnection.getresponsecode() == 200){
    return bitmapfactory.decodestream(urlconnection.getinputstream());
   }
  } catch (malformedurlexception e) {
   e.printstacktrace();
  } catch (ioexception e) {
   e.printstacktrace();
  }
  return null;
 }
