I'm looking for a very basic function. I'm trying to design an app and all I want it to do is load an image from a URL. I've found a few questions and websites, but they all seem to be older and dated, but what I think I'm having issues with is linking the code to activity main.xml for ImageView.

任何建议或链接你，我将不胜AP preciate，谢谢你。

Any suggestions or links you have I would greatly appreciate, thank you.

推荐答案

在这里，这是我如何从URL中的图像视图
显示图像 您必须调用从线程比主线程

Here, this is how I display image from url in the image view
you have to call this code from thread other than main thread

ImageView img = (ImageView) findViewById(R.id.imageView1);
try {
        URL url = new URL("Your URL");
        //try this url = "http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg"
        HttpGet httpRequest = null;

        httpRequest = new HttpGet(url.toURI());

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

        HttpEntity entity = response.getEntity();
        BufferedHttpEntity b_entity = new BufferedHttpEntity(entity);
        InputStream input = b_entity.getContent();

        Bitmap bitmap = BitmapFactory.decodeStream(input);

        img.setImageBitmap(bitmap);

    } catch (Exception ex) {

    }

要小心不要忘了周围的code与尝试catch（我已经做了，在这个code）

Be careful don't forget to surround the code with try catch(I have already done that in this code)

也可以使用web视图加载从URL图像

or you can use webview to load image from url

WebView web = (WebView) findViewById(R.id.webView1);
web.loadUrl("Your Url");

如果你要加载的资源文件夹URL的图像将这样开始 文件：///android_asset/yourimage.jpg
其他正常的互联网网址类似这样的 <一href="http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg">http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg"

if you are trying to load image from the assets folder url will start like this "file:///android_asset/yourimage.jpg"
else normal internet url like this "http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg"

希望这对你的作品 好运

hope this works for you Good Luck
