try {

BitmapFactory.Options opt = new BitmapFactory.Options();

opt.inPreferredConfig = Bitmap.Config.RGB_565;

opt.inPurgeable = true;

opt.inInputShareable = true;

FileInputStream fis = new FileInputStream(url);

return BitmapFactory.decodeStream(fis, null, opt); // /把流转化为Bitmap图片

} catch (FileNotFoundException e) {

e.printStackTrace();
