SparseArray instead HashMap Android example

example to getbitmap cache


Old code with HashMap

 Map<Integer, Bitmap> _bitmapCache = new HashMap<Integer, Bitmap>();  
   private void fillBitmapCache() {  
     _bitmapCache.put(R.drawable.icon, BitmapFactory.decodeResource(getResources(), R.drawable.icon));  
     _bitmapCache.put(R.drawable.abstrakt, BitmapFactory.decodeResource(getResources(), R.drawable.abstrakt));  
     _bitmapCache.put(R.drawable.wallpaper, BitmapFactory.decodeResource(getResources(), R.drawable.wallpaper));  
     _bitmapCache.put(R.drawable.scissors, BitmapFactory.decodeResource(getResources(),   
   }  
 Bitmap bm = _bitmapCache.get(R.drawable.icon);  

Use new SparseArray instead for better performance.
