Question

我有一个带有setOntouchlistener的图像视图。当触摸图像时，将显示展开的底页中有关触摸区域的信息。

当我运行该应用程序时，所有内容最初都按预期显示，我可以在屏幕底部看到在图像底部显示的bottomSheet的一览表。

但是，一旦我触摸屏幕，图像视图就会显示在底部页面上方，因此我看不到底部页面。

当我为imageview注释掉setOnTouchListener时，这不再是问题。我也尝试使用片段来导致完全相同的问题。有人可以为此建议一些解决方案吗？

我尝试将触摸侦听器添加到bottomSheet的LinearLayout和底部工作表中的imageview中。带有return false但不能解决问题。

下面是重要代码的摘录。

我的活动中的setOntouchListener
