I am trying to set image on imageview but image is not show. I am reading image url from json data and then trying to set it on ImageView but my image is not visible. No any

Solution 1:

Please Use below code for get image from url and display into imageview.

publicclassimageextendsActivity {
    /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Bitmapbitmap= DownloadImage("http://www.gophoto.it/view.php?i=https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_KK4poNaL7XzYaizHU4faYysXvLc3rDSNRCME5hjdr3bMnNzefMmHOi-GuaSONhixPE34YtlICE7RVWEN55W7r2l2fs8zGCpdVJPe7OoEqY74Iaq5IO6D20W-Pl99h_RVElxSjtwIGrx9/s1600/Sachin+Tendulkar.png");

        RelativeLayoutmRlayout1= (RelativeLayout) findViewById(R.id.mRlayout1);
        Drawable d=newBitmapDrawable(bitmap);
        mRlayoutLogin.setBackgroundDrawable(d);
    }

    private InputStream OpenHttpConnection(String urlString)throws IOException {
        InputStreamin=null;
        intresponse= -1;

        URLurl=newURL(urlString);
        URLConnectionconn= url.openConnection();

        if (!(conn instanceof HttpURLConnection))
            thrownewIOException("Not an HTTP connection");

        try {
            HttpURLConnectionhttpConn= (HttpURLConnection) conn;
            httpConn.setAllowUserInteraction(false);
            httpConn.setInstanceFollowRedirects(true);
            httpConn.setRequestMethod("GET");
            httpConn.connect();
            response = httpConn.getResponseCode();
            if (response == HttpURLConnection.HTTP_OK) {
                in = httpConn.getInputStream();
            }
        } catch (Exception ex) {
            thrownewIOException("Error connecting");
        }
        return in;
    }

    private Bitmap DownloadImage(String URL) {
        Bitmapbitmap=null;
        InputStreamin=null;
        try {
            in = OpenHttpConnection(URL);
            bitmap = BitmapFactory.decodeStream(in);
            in.close();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        return bitmap;
    }
}

Solution 2:

you can view image by using this code.

try {
    bitmap = BitmapFactory.decodeStream((InputStream)new URL(url).getContent());
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Solution 3:

It seems you are downloading the image from UI thread. this will block the UI thread and will give you not responding error. as an easy way, you can use a library like Universal Image Loader

Universal Image Loader - GitHub

this will manage the image loading for you and avoid problems like incorrect urls, Out Of Memory error.
