#Version 2 Goals X1. Eliminate strings from detail levels X1. Eliminate ImageViews as Tiles X1. Single package X1. Eliminate hacked core classes X1. Better thread management

1. Issues Xa. Disable zoom on double tap feature request - extend and override onDoubleTap (no super) Xb. Smooth scale to position feature request -c. Skipped detail level feature request Xd. moveMarker(x, y) overrides anchor feature request Xe. setScaleLimit does not work with setScaleToFit(false) bug X1. Allow layer insertion and scaling layer insertion X1. Eliminate downsample paradigm X1. Include a sample downsample X1. Remove LRU cache dependency X1. Use more framework-provided functionality, like GestureListener X1. End fling (test for change) X1. Make most private into protected for extensibility X1. Other Issues Xa. when detail levels change with no downsample, there's a moment when the old one dies before the new one is done. X1. Don't use detail manager as intermediary anymore X1. BitmapDecoder to TileProvider or Adapter paradigm X1. Remove TileSetSelector -1. consider generics in the arbitrary data Object for detail levels X1. optimize data structures X1. optimize tile set comparisons -1. set downsample (addView imageView)?

#TileView

Update: this repo has been updated to include a demo app, and the widget code as an Android Studio library module. All other TileView related repos will be deprecated.

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.

###Documentation Javadocs are here. Wiki is here.

###Installation Gradle:

compile 'com.qozix:tileview:1.0.15'

###Demo A demo application, built in Android Studio, is available in the demo folder of this repository. Several use-cases are present; the RealMapTileViewActivity is the most substantive.

###Quick Setup

1. Tile an image into image slices of a set size, e.g., 256x256 (instructions)
2. Name the tiles by the row and column number, e.g., 'tile-2-3.png' for the image tile that would be at the 2nd column from left and 3rd row from top.
3. Create a new application with a single activity ('Main').
4. Save the image tiles to your assets directory.
5. Add compile 'com.qozix:tileview:1.0.15' to your gradle dependencies.
6. In the Main Activity, use this for onCreate:

@Override
protected void onCreate( Bundle savedInstanceState ) {
  super.onCreate( savedInstanceState );
  TileView tileView = new TileView( this );
  tileView.setSize( 2000, 3000 );  // the original size of the untiled image
  tileView.addDetailLevel( 1f, "tile-%col%-%row%.png");
  setContentView( tileView );
}

That's it. You should have a tiled image that only renders the pieces of the image that are within the current viewport, and pans and zooms with gestures.
