BitmapFactory 및 HTTPUrlConnection 문제

Question

URL에서 이미지를 삽입하는 데 문제가 있습니다. I는 BitmapFactory로부터 스트림을 디코딩 할 때, 애플리케이션은

온 클릭 방법

@Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Bundle extras = getIntent().getExtras(); 
       String temp = (String) extras.get("temp"); 

       String ikona = (String) extras.get("ikony"); 
       URLs = "http://openweathermap.org/img/w/"+ikona+".png"; 
       Log.d("asd",URLs); 

       try { 
        URL url = new URL(URLs); 
        Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream()); // here is the problem 
        imageView1.setImageBitmap(bmp); 
       } catch (MalformedURLException e) { 
        Log.d("asd","malformedURLException"); 
        e.printStackTrace(); 
       } catch (IOException e) { 
        Log.d("asd","IOException"); 
        e.printStackTrace(); 
       } 



      } 
     }); 

문제점 맵 BMP = BitmapFactory.decodeStream에 충돌 (url.openConnection().는 getInputStream())

Answer 1

url에서 비트 맵 이미지를 직접 스레드에서 실행할 수 없습니다.

Bundle extras = getIntent().getExtras(); 
String temp = (String) extras.get("temp"); 

String ikona = (String) extras.get("ikony"); 
URLs = "http://openweathermap.org/img/w/"+ikona+".png"; 
Log.d("asd",URLs); 

Thread thread = new Thread(new Runnable() { 

    public void run() { 
     try { 
      URL url = new URL(URLs); 
      Bitmap bmp= BitmapFactory.decodeStream((InputStream) new URL(url).getContent()); 
      imageView1.setImageBitmap(bmp); 
     } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}); 
thread.start(); 

Answer 2

메인 스레드에서 네트워크 호출을 할 수 없습니다. 별도의 스레드 또는 AsyncTask에서 비트 맵 디코딩을 수행합니다. 또한 인터넷 사용 허가를 받았는지 확인하십시오.
