any suggestion?

hi use code resize image @ runtime.

public static bitmap decodesampledbitmapfromresource(resources res, int resid,int reqwidth, int reqheight) {      final bitmapfactory.options options = new bitmapfactory.options();     options.injustdecodebounds = true;     bitmapfactory.decoderesource(res, resid, options);      // calculate insamplesize     options.insamplesize = calculateinsamplesize(options, reqwidth, reqheight);      // decode bitmap insamplesize set     options.injustdecodebounds = false;     return bitmapfactory.decoderesource(res, resid, options); }  public static int calculateinsamplesize(             bitmapfactory.options options, int reqwidth, int reqheight) {     // raw height , width of image     final int height = options.outheight;     final int width = options.outwidth;     int insamplesize = 1;      if (height > reqheight || width > reqwidth) {          final int halfheight = height / 2;         final int halfwidth = width / 2;          // calculate largest insamplesize value power of 2 , keeps both height , width larger requested height , width.          while ((halfheight / insamplesize) > reqheight                 && (halfwidth / insamplesize) > reqwidth) {             insamplesize *= 2;         }     }      return insamplesize; }
