Show Android App Widget in all homescreens

I am developing an android wid开发者_开发百科get to show in the homescreen. Now, I can show the widget in main homescreen. Now, is there any way to show that widget every homescreens (in most of the devices there are several homescreens where we can swipe to left or right from the homescreen)?

Only if the user manually adds your app widget multiple times.

These depends on entirely on the home screen app. Some home screen apps could certainly implement a UI to have a widget like this. The launcher that is part of stock Android does not have such a facility.
