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;
}
