java Multiple TouchImageView在调用一个的setImageDrawable时重置另一个

Question

我试图在一个视图中使用多个TouchImageView。然后在TouchImageView中单击鼠标从图库中拾取图像以在TouchImageView中显示。但问题是，当我在一个TouchImageView中从gallery设置新图像时，另一个也被重置意味着最后一次缩放仍然在TouchImageView的右侧，但图像内部的最后一个位置被重新定位

这是我的密码：

我想不出问题出在哪里，我还试着通过注释TouchImageView类的onSaveInstanceState（）和onRestoreInstanceState（）。但这也不能解决问题。一些帮助将是非常值得的。提前谢谢
