android - 什么是触摸模式，为什么它对 ActivityTestRule 类很重要？

Question

ActivityTestRule类在其构造函数中接受 initialTouchMode 参数。类(class)引用(或在线任何地方)中没有解释这一点，除非如下:

initialTouchMode - true if the Activity should be placed into "touch mode" when started

“触摸模式”究竟是什么意思？在 ActivityTestRule 中设置 initialTouchMode 有什么影响？ true 还是 false？ (我看到这个参数的默认值是false)。

Answer 1

触摸模式会影响 View 焦点和选择的工作方式。

The touch mode is a state of the view hierarchy that depends solely on the user interaction with the phone. By itself, the touch mode is something very easy to understand as it simply indicates whether the last user interaction was performed with the touch screen.

...

In touch mode, there is no focus and no selection.
