public Bitmap ProcessingBitmap(int image) { |
// TODO Auto-generated method stub |
Bitmap bm1 = null; |
Bitmap newBitmap = null; |
final String data =getIntent().getExtras().getString("keys"); |
bm1 = ((BitmapDrawable) Viewactivity.this.getResources() |
.getDrawable(image)).getBitmap(); |
Config config = bm1.getConfig(); |

//private String[] TEXTS; |
public CustomList(Context context, int[] images){ |
this.IMAGES = images; |
//this.TEXTS = texts; |
this.sContext = context; |
inflator = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); |
} |
@Override |
public int getCount() { |
// TODO Auto-generated method stub |
return IMAGES.length; |
} |
@Override |
