Question

我正在使用以下功能将远程图像加载到ImageView。图像肯定存在于我正在尝试加载它的URL但是当我调用该函数并尝试显示图像时，ImageView仍为空白。

public static void setImage(ImageView view, String url) throws IOException {
    final URLConnection conn = new URL(url).openConnection();
    conn.connect();
    final InputStream is = conn.getInputStream();

    final BufferedInputStream bis = new BufferedInputStream(is, 100000);

    final Bitmap bm = BitmapFactory.decodeStream(bis);
    bis.close();
    is.close();

    view.setImageBitmap(bm);
}

Answer 1

使用https://github.com/kaeppler/ignition可能是一个选项，尝试使用RemoteImageView，它非常容易使用。

Answer 2

试试这个

private void setImage(String urlStr, ImageView iv) throws ClientProtocolException, IOException {
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpGet request = new HttpGet(urlStr);
    HttpResponse response = httpClient.execute(request);
    InputStream is = response.getEntity().getContent();
    TypedValue typedValue = new TypedValue();
    typedValue.density = TypedValue.DENSITY_NONE;
    Drawable drawable = Drawable.createFromResourceStream(null, typedValue, is, "src");
    iv.setImageDrawable(drawable);
}

注意：它同步加载。如果它工作，你的下一步应该加载一个线程，不要阻塞主线程。

Answer 3

我使用Prime来加载所有图片。它可以轻松应对。

Answer 4

这对我有用：

    Bitmap bitmap = null;

    HttpGet httpRequest = null;


    try {
            URL url = new URL(your_url);
            httpRequest = new HttpGet(url.toURI());

            HttpClient httpclient = new DefaultHttpClient();
            HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);

            HttpEntity entity = response.getEntity();
            BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity); 
            InputStream instream = bufHttpEntity.getContent();
            bitmap = BitmapFactory.decodeStream(instream);
    } catch (URISyntaxException e) {
            e.printStackTrace();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
    }

试图将远程图像加载到ImageView，但没有任何反应
