ImageLoader

Image loader library for Android. Allows you to build your own image loader that will do exactly what you want. Almost unlimited customization.

Usage

dependencies {

  implementation 'com.budiyev.android:image-loader:1.8.2' 
}

Basic usage sample

Basic implementation automatically cares about memory caching storage caching

public class MainActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ImageView view = findViewById(R.id.image_view);

 ImageLoader.with(this).from("https://some.url/image").into(view).load();

  
}
 
}

Simple singleton implementation

You can build your own loader using builder

/**  * Simple image loader that automatically cares about memory and storage caching,  * read documentation for more info  */ public final class MyImageLoader {

  private static volatile MyImageLoader sInstance;
  private final ImageLoader<Uri> mLoader;

private MyImageLoader(@NonNull Context context) {

mLoader = ImageLoader.builder(context).uri().memoryCache().storageCache().build();

  
}

/** 
  * Load image form {
@code url
}
 to {
@code view
}
 
  * 
  * @param url  Source URL 
  * @param view Target image view 
  */
  @MainThread
  public void load(@NonNull String url, @NonNull ImageView view) {

mLoader.load(DataUtils.descriptor(Uri.parse(url)), view);

  
}

/** 
  * Get (or create, if not exist) loader instance 
  * 
  * @param context Context 
  * @return Loader instance 
  */
  @NonNull
  public static MyImageLoader with(@NonNull Context context) {

MyImageLoader instance = sInstance;

if (instance == null) {

 synchronized (MyImageLoader.class) {

  instance = sInstance;

  if (instance == null) {

instance = new MyImageLoader(context);

sInstance = instance;

  
}

 
}

}

return instance;
  
}

/** 
  * Clear memory cache if it exists, would be good to call this method in 
  * {
@link Application#onTrimMemory(int)
}
 method, 
  * read documentation for more info 
  */
  public static void clearMemoryCache() {

MyImageLoader instance = sInstance;

if (instance != null) {

 instance.mLoader.clearMemoryCache();

}

  
}
 
}

Implementation usage sample

public class MainActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ImageView view = findViewById(R.id.image_view);

MyImageLoader.with(this).load("https://some.url/image", view);

  
}
 
}

WhirlyGlobe-Maply is a toolkit with two parts, hence the dash. The WhirlyGlobe part is an interactive 3D globe. The Maply part is an interactive 2D map. There are separate view controllers (on iOS) for each, but otherwise they share 95% of their code.

Parallax everywhere (PEW) is a library with alternative android views using parallax effects.

How it works?

  • Any parallax views (PEW*) needs to be inside a view with scroll events, ej: scrollView, listView, gridView....
  • Parallax effect on views will be related to its position on device screen.
  • Parallax effect in ImageView is calculated with left image in Scale mode centerCrop, centerInside or center. You can't make more parallax effect.
  • Parallax effect in no image views needs a size parallax parameter (read: Attributes)

The TileView widget is a subclass of ViewGroup that provides a mechanism to asynchronously display tile-based images, with additional functionality for 2D dragging, flinging, pinch or double-tap to zoom, adding overlaying Views (markers), built-in Hot Spot support, dynamic path drawing, multiple levels of detail, and support for any relative positioning or coordinate system.
