有一个ListView，其中对于List的每个元素，您有3个按钮用于3个不同的选项，当您进入屏幕时，ImageButton的图像中没有溢出问题，但是当您第一次滚动时，源代码就会开始如下图所示溢出

当您向上或向下滚动时，图像会丢失中心并且未对齐，此问题在iOS中不会发生，仅在Android（版本6,7,8和9）中会发生，显然这是一个问题，例如Android渲染图片

我尝试过，将ImageButton控件更改为Button，问题仍然存在，还尝试将“ Aspect”属性分配给ImageButton，但是我没有获得成功的结果，如何解决此问题有帮助吗？然后我的代码XAML

如何避免这种行为？对我有帮助吗？
