java - Android查看performClick()和callOnClick()的区别

Question

performClick()和callOnClick()在用法上有什么区别？看起来他们的工作方式是一样的，那为什么View有两个方法呢？

Answer 1

这两种方法的 Javadoc 也很容易解释:

public boolean performClick ()

Added in API level 1

Call this view's OnClickListener, if it is defined. Performs all normal actions associated with clicking: reporting accessibility event, playing a sound, etc.

---

public boolean callOnClick ()

Added in API level 15

Directly call any attached OnClickListener. Unlike performClick(), this only calls the listener, and does not do any associated clicking actions like reporting an accessibility event.
