auto scroll a Gallery widget

阅读更多关于 auto scroll a Gallery widget

I need to implement a gallery which scrolls one item at a time, and which can do 'autoscroll': i.e. every couple of seconds, it automatically scrolls to the next item. As per this thread: Android: Programmatically animate between images in Gallery widget , I extended Gallery, overriding onFling to ignore the fling event and instead simulate a DPAD arrow left or right in order to move a single item at a time: @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { int kEvent; if(isScrollingLeft(e1, e2)){ //Check if scrolling left kEvent = KeyEvent

Resize android datepicker control

阅读更多关于 Resize android datepicker control

How can one resize the initial size of android datepicker control to be smaller or bigger. Is there only way to reimplement it? I haven't been able to figure out a way to resize it, but have seen implementations where they utilize the DatePicker as a dialog. The date is rendered as TextView with an edit button, which launches the DatePicker dialog.
