Android Webview，未调用startActionMode（）

我需要在我的网络视图中有一个自定义的文本选择菜单（CAB）。
正如所回答的，我重写了startActionMode方法，它工作得很好

问题：

在一些设备（据我所测试的两台华为设备）中，webview显示android默认菜单，并且根本不调用

startActionMode

方法。
我覆盖了其他方法，当我选择一些文本时，唯一调用的方法是

showContextMenu（）

。

我曾考虑过在这种情况下使用JS解决方案，但我更喜欢用本机解决方案更简单地解决这个问题

此外，当我重写

showContextMenu（）

方法时，我注意到工作正常的设备和工作不正常的设备的堆栈跟踪是不同的

设备的堆栈跟踪工作正常：
