} 그리고 각각의 XML은 여기에 있습니다 :

어댑터 GET보기에서
<com.ifap.util.NewTouchImageView 
    android:id="@+id/image" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:padding="10dip" 
    android:scaleType="matrix" 
    android:src="@drawable/loading" 
    android:contentDescription="@string/image_desc" /> 

: 공공보기의 getView (INT 위치보기 convertView, 뷰 그룹의 부모) {

ViewHolder holder; 
    if (convertView == null) { 
     convertView = inflater.inflate(R.layout.item, null); 
     holder = new ViewHolder(); 
     holder.icon = (NewTouchImageView) convertView 
       .findViewById(R.id.image); 
    } else 
     holder = (ViewHolder) convertView.getTag(); 
imageLoader.DisplayImage(URL, holder.icon); 

    return convertView; 

} 

하여 ImageLoader .Java에서 here

서버에서 이미지가로드 될 때까지 imageview 안에 임시 이미지를 표시하려면 어떻게합니까?

안녕하세요 @ silverback : 어떤 생각이 드십니까? – Umesh

대신에 android : src = "@ drawable/loading"을 사용하면 기본적으로 표시 할 임시 이미지 이름을 지정할 수 있습니다. 또는 holder.icon.setImageBitmap (bitmapImage)을 설정할 수 있습니다. imageLoader.DisplayImage (URL, holder.icon)를 실행합니다. 에 uiThread. 그래서 그것은 이미지가 다운로드 되 자마자 UI를 업데이트 할 것입니다.

당신이 저를 구해 주셨습니다, 제 친구 ..... holder.icon.setImageDrawable (drawableImage)를 사용했습니다 ... 고마워요. – Umesh
