HashMap에서 URL을 이미지로 변환하는 방법은 무엇입니까?

Question

이 내가 모두 Android에 이미지 및 제목을 표시 할 것입니다 원하는 내 Json 인코딩 된 코드입니다하지만 난 이미지

{"lists": 
    [{"post_title":"kigs", 
    "post_img":"post_img":"http://truzzinfotech.com/wp-content/uploads/2014/04/19-150x150.jpg"}, 

    {"post_title":"Lacolline", 
    "post_img":"http://truzzinfotech.com/wp-content/uploads/2014/04/19-150x150.jpg"}, 

    {"post_title":"Cricket", 
    "post_img":"http://truzzinfotech.com/wp-content/uploads/2014/047-150x150.jpg"},  
    ], 
    "success":1} 

를 표시 할 수없는 오전이 점점 이미지에 대한 내 안드로이드 코드 제목

이 같이 시도 ListActivity를 확장 , 이미지 뷰 visit here

Answer 2

에서보기 이미지

JSONArray data = yourjson.getJSONArray("lists"); 

ArrayList<String> imgurls = new ArrayList<String>(); 

for(int i = 0; i < data.length(); i++){ 
    imgUrls.add(data.getJSONObject(i).getString("post_img")) 
} 

당신의 하나가 처리해야하는 더러운 물건의 대부분 이미지보기 경우

com.android.volley.toolbox.NetworkImageView 
     android:id="@+id/networkImageView" 
     android:layout_width="150dp" 
     android:layout_height="170dp" 
     android:layout_centerHorizontal="true" /> 

NetworkImageView 네트워킹 중에이하는 구글에 의해 발리 라이브러리를 사용할 수 있습니다 정말 잘 관리하는 목록보기의 일부입니다.

ImageLoader mImageLoader; 
NetworkImageView mNetworkImageView; 
private static final String IMAGE_URL = 
    "http://developer.android.com/images/training/system-ui.png"; 
... 

// Get the NetworkImageView that will display the image. 
mNetworkImageView = (NetworkImageView) findViewById(R.id.networkImageView); 

// Get the ImageLoader through your singleton class. 
// mImagaLoader is actually the request Queue of the manages all the caching 
// and requesting image from the network in not present in cache 
mImageLoader = MySingleton.getInstance(this).getImageLoader(); 

// Set the URL of the image that should be loaded into this view, and 
// specify the ImageLoader that will be used to make the request. 
mNetworkImageView.setImageUrl(IMAGE_URL, mImageLoader);
