Android App Display Image From URL

Question

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.

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

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) {

    }

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

or you can use webview to load image from url

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

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"

hope this works for you Good Luck

There is an opensource library called imageloader. It is widely used, you can use it directly or make code similar to it.
