问题 I want to create a clock widget with a second watch hand. And yes, I already read that widgets aren't designed to be refreshed that fast. The widget should become an egg timer which is only animated when the user actively starts it so it is probably not that bad for battery life and performance at all because I only use this high refresh rate when the user actively uses it... Currently I start a service which posts a delayed runnable every 1000 milliseconds. Handler

问题 Alright I'm trying to build an activity that has a horizontal scrollview, that the user can swipe through, to view different "pages". My train of thought is these "pages" will be views.

问题 I'm quite new developing for Android so I have a very basic question. Basically, I have two screen layouts, one for portrait and another for landscape orientation. I use the folders res/layout and res/layout-land. Both orientations are drawn fine, but I have different widgets (buttons) for each orientation, btnPortrait and btnLandscape.
