Hi,All, I am thinking about the Android OS principle, and do much examples to verify that. One question excuse me much days, and I have tried many ways, that is HOW TO SAVE THE SCREEN？
And I got some viewpoint. 1, For a Window, it has no right to draw its child view's canvas. So, in our activity, we can't draw directly to sub-view. activity could just only send a message(call a API) to underlying views. It's the view's responsibility to draw. Maybe this is function right, just like Human Right. 2, It's likely that View class does not give programmer one draw buffer access method, so in a view, we could not get the current drawing pixels. Even that we could enable the drawCache, or canvas.setBitmap, then we could get the cacheable pixels. But that time after action, not time on action. Could anybody have other idea to capture the screen programmtically? Regards!
