我正在尝试进行字母检查。我有一个ImageView11，它显示你必须猜测的随机字母表。 imageView_alphabet_image_1和imageView_alphabet_image_2将显示我必须猜测的两个选项，并且我会将ImageView11图像拖动到显示正确的ImageView上。但我能做到这一点只有第一次当我刷新点击它总是显示不正确敬酒无法进行拖放

书面方式真也接受了错误的字母图像后，以及在显示敬酒两次 – 2015-04-06 11:22:32
@Ashutoshsingh - 你只检查的ImageView的绘制。没有计算拖动的imageview的位置。所以如果你通过_imgView_alphabetImage_1拖动图片，那么它将检查两个imageview。所以你需要检查第一个用户在哪个图像视图上拖动图像。 – 2015-04-06 11:29:00
你可以帮我pllzzzz .....怎么做？ – 2015-04-07 07:50:30
