How to call onClick(View v) method explicitly in an Android? Is it possible?

问题

I want to call an onClick(View v) of other class from my activity's method onCreate(). Is it possible?

Because I have a Popupwindow in an onClick method of other class, so when an orientation changes, I want my landscape mode's popupwindow to be intact and appear at runtime. How can it be done?

Thanks in advance!

回答1:

Assuming that the onClick() you want to call is for a View x, use either x.performClick() or x.callOnClick(). Check their javadoc in the Developers Guide for more details.

Notice that you have to have a handle to x. If your orientation changes, you should destroy the PopupWindow and re-display it, which should work.
