Answer 1

URL에서 이미지를 가져 와서 imageview에 표시하려면 아래 코드를 사용하십시오. AsycTask를 사용하여 다운로드하는 동안

public class image extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     Bitmap bitmap = DownloadImage("http://www.gophoto.it/view.php?i=http://1.bp.blogspot.com/-2LTvCCufBKc/T3L3KgcTj2I/AAAAAAAABbQ/Ki60e1LU9sE/s1600/Sachin%2BTendulkar.png"); 

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

    private InputStream OpenHttpConnection(String urlString) throws IOException { 
     InputStream in = null; 
     int response = -1; 

     URL url = new URL(urlString); 
     URLConnection conn = url.openConnection(); 

     if (!(conn instanceof HttpURLConnection)) 
      throw new IOException("Not an HTTP connection"); 

     try { 
      HttpURLConnection httpConn = (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) { 
      throw new IOException("Error connecting"); 
     } 
     return in; 
    } 

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

Answer 2

Drawable drawable = LoadImage(ImageURL); 
PhotoImageView.setImageDrawable(drawable);  
//PhotoImageView is the ImageView in which you want to load your image from server 

public Drawable LoadImage(String url) 
{ 
    try 
    { 
     InputStream is = (InputStream) new URL(url).getContent(); 
     Drawable d = Drawable.createFromStream(is, "src name"); 
     return d; 
    } 
    catch (Exception e) 
    { 
     System.out.println("Exc=" + e); 
     return null; 
    } 
}

보통 당신은 ProgressBar의 회전을 보여

public class Downloader extends AsyncTask<String,Integer,Bitmap> { 

    @Override 
    protected void onPreExecute() { 
     // show spinning progress bar 
    } 

    @Override 
    protected Bitmap doInBackground(String... arg0) { 
     // download the image 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Bitmap downloadedImage) { 
     // hide spinning progress bar 
     // show downloaded image 
    } 

}

가 당신을 도울 수있는이보십시오.

class DownloadImage extends AsyncTask<Void, Void, Void> { 

    private ProgressDialog bar; 

    @Override 
    protected void onPostExecute(Void result) { 
     super.onPostExecute(result); 
     bar.dismiss(); 
    } 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     bar = new ProgressDialog(context); 
     bar.setIndeterminate(true); 
     bar.setTitle(context.getString(R.string.app_name)); 
     bar.setMessage(context.getString(R.string.please_wait)); 
     bar.show(); 
    } 

    @Override 
    protected Void doInBackground(Void... arg0) { 
     downloadImage(); 
     return null; 
    } 

    void downloadImage() { 
     //Put the logic for download image from url 
    } 
} 

또는 시도 무슨 here.
