Quick Setup

1. Include library

Manual:

• Download JAR
• Put the JAR in the libs sub folder of your Android project

2. Android Manifest

<manifest>
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- Include next permission if you want to allow UIL to cache images on SD card -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    ...
    <application android:name="MyApplication">
        ...
    </application>
</manifest>

 3. Application class

public class MyApplication extends Application {
 @SuppressWarnings("unused")
 @Override
 public void onCreate() {
  if (Config.DEVELOPER_MODE
    && Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
   StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
     .detectAll().penaltyDialog().build());
   StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
     .detectAll().penaltyDeath().build());
  }
  super.onCreate();
  initImageLoader(getApplicationContext());
 }

 public static void initImageLoader(Context context) {
  // This configuration tuning is custom. You can tune every option, you
  // may tune some of them,
  // or you can create default configuration by
  // ImageLoaderConfiguration.createDefault(this);
  // method.
  ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(
    context).threadPriority(Thread.NORM_PRIORITY - 2)
    .denyCacheImageMultipleSizesInMemory()
    .discCacheFileNameGenerator(new Md5FileNameGenerator())
    .tasksProcessingOrder(QueueProcessingType.LIFO).enableLogging() // Not
                    // necessary
                    // in
                    // common
    .build();
  // Initialize ImageLoader with configuration.
  ImageLoader.getInstance().init(config);
 }

 static class Config {
  public static final boolean DEVELOPER_MODE = false;
 }
}

 4 Common Interface

public interface Common {

 DisplayImageOptions options = new DisplayImageOptions.Builder()
   .showStubImage(R.drawable.ic_stub)
   .showImageForEmptyUri(R.drawable.ic_empty)
   .showImageOnFail(R.drawable.ic_error).cacheInMemory().cacheOnDisc()
   .build();
 
 
 // Image Loader 
 ImageLoader imageLoader = ImageLoader.getInstance();

 AnimateFirstDisplayListener animationListener = new AnimateFirstDisplayListener();

 static class AnimateFirstDisplayListener extends SimpleImageLoadingListener {

  static final List<String> displayedImages = Collections
    .synchronizedList(new LinkedList<String>());

  @Override
  public void onLoadingComplete(String imageUri, View view,
    Bitmap loadedImage) {
   if (loadedImage != null) {
    ImageView imageView = (ImageView) view;
    boolean firstDisplay = !displayedImages.contains(imageUri);
    if (firstDisplay) {
     FadeInBitmapDisplayer.animate(imageView, 500);
     displayedImages.add(imageUri);
    }
   }
  }
 }

5 Image Display Class

public class MonthCalendarAdapter extends BaseAdapter implements Common {

 private LayoutInflater mInflater;
 private ArrayList<MonthCalendarModel> ListData;
 public Context con;

 public MonthCalendarAdapter(Context con, ArrayList<MonthCalendarModel> data) {
  // TODO Auto-generated constructor stub
  mInflater = LayoutInflater.from(con);
  ListData = data;
  this.con = con;
 }

 @Override
 public int getCount() {
  // TODO Auto-generated method stub
  return ListData.size();
 }

 @Override
 public Object getItem(int position) {
  // TODO Auto-generated method stub
  return ListData.get(position);
 }

 @Override
 public long getItemId(int position) {
  // TODO Auto-generated method stub
  return 0;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
  // TODO Auto-generated method stub
  ViewHolder holder;

  if (convertView == null) {
   convertView = mInflater.inflate(R.layout.activity_month_calendar,
     null);
   holder = new ViewHolder();
   holder.name = (TextView) convertView
     .findViewById(R.id.FestivalName);
   holder.content = (TextView) convertView
     .findViewById(R.id.FestivalContent);
   holder.date = (TextView) convertView
     .findViewById(R.id.FestivalplaceName);
   holder.icon = (ImageView) convertView
     .findViewById(R.id.profile_image);
   convertView.setTag(holder);

  } else {
   holder = (ViewHolder) convertView.getTag();
  }

  holder.name.setText(ListData.get(position).getName().toString());
  Log.w("Content", ListData.get(position).getInfo().toString());
  holder.content.setText("dsfsdf  nsafn ");
  holder.date.setText(ListData.get(position).getPlace().toString());
  imageLoader.displayImage(ListData.get(position).getHimg(), holder.icon,
    options, animationListener);
  return convertView;
 }

 static class ViewHolder {
  TextView name;
  TextView content;
  TextView date;
  ImageView icon;
 }

}
