我正在从 url 检索图像并将它们显示在imageview. 但我的代码给了我空消息。

ImageView imageview = (ImageView) findViewById(R.id.imageView1);
try {
    Uri uri=Uri.parse("http://10.0.2.2:8083/call/rahul.jpg");
    // uri.buildUpon().appendQueryParameter("key", "Android developer");
    URI u = new URI(uri.toString());
    System.out.println("path is "+u);
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet();
    httpget.setURI(u);
    //httpget.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();
    is = entity.getContent(); 

    Bitmap bitmap = BitmapFactory.decodeStream(is);
    imageview.setImageBitmap(bitmap); 
} catch(Exception e) {
    System.out.println("this is the error "+e.getMessage()); 
}

尝试这个：

ImageView imageview = (ImageView) findViewById(R.id.imageView1);
mBitmap = BitmapFactory.decodeStream((InputStream) new URL(http://10.0.2.2:8083/call/rahul.jpg).getContent());
imageview .setImageBitmap(mBitmap);

好吧，既然您说我的建议对您很有效，我想我应该将其作为答案提交。我观察到您似乎距离一个可行的解决方案还有很长的路要走，而且由于在您可能希望使用诸如android-query之类的库之前，这个问题已经解决了很多次。我与那个图书馆没有任何关系——我以前自己也用过。另外，由于我没有从技术上回答你的问题，虽然我解决了你的问题，但我最好为绿色勾号多做一点，嗯？

您对库的使用看起来不错，并且您不需要调用回收（顺便说一句，您可以在 Google 上轻松找到）。请注意，您也可以用它做很多其他的好事情，例如在加载图像时淡入淡出，如果它们非常大，则在加载时对其进行下采样等等。您可以在 android-query 网站上找到很多示例。

至于您对它是否免费的询问，许可证是在我链接到的主页上声明的，在靠近顶部的左侧。它是Apache 许可证 2.0。简而言之，此许可证允许您自由使用该库，只要您在您的应用程序的任何发行版中包含 Apache 许可证的副本并明确提及您在该许可证下使用的任何库。或者您可以阅读他们的常见问题解答中的简介。您通常会在您的应用程序中为此类事情放置一个 about 屏幕，这清楚地表明您正在使用 Apache 2.0 许可证下的 android-query 库，并带有可查看的许可证副本。正确的归属：我想你会同意，在这个许可下你可以找到这么多有用的东西，这是一个很小的代价：o）

祝你的应用好运！
