AndroidGUI29：获取ImageView中的图像需要注意的问题(10)

                  Bitmap ret_bitmap =data.getParcelableExtra("ret_bitmap");

                  iv_photo.setScaleType(ScaleType.FIT_XY);

                  iv_photo.setImageBitmap(ret_bitmap);

              }

           super.onActivityResult(requestCode,resultCode, data);

      }

      // 简单的比较两个图像是否一致

    private boolean compare2Image(Bitmap bmp1,Bitmap bmp2)

    {

          int iteration = 0;

          int width = bmp1.getWidth();

          int height = bmp1.getHeight();

          if(width != bmp2.getWidth()) return false;

          if(height != bmp2.getHeight()) return false;

          if(width < height)

          {

                iteration = width;

          }

          else

          {

                iteration = height;

          }

          for(int i = 0; i < iteration; ++i)

         {              

                if(bmp1.getPixel(i, i) != bmp2.getPixel(i,i)) return false;

          }

          return true;

      }

}

5.     另外创建一个Activity，取名为TakePicture，并为它准备一个对应的layout文件takepicture.xml：

        <?xml version="1.0"encoding="utf-8"?>

        <LinearLayout
