问题 When I'm adding single widget I can configure it properly and it's updated as supposed to after initial configuration. But when I add second and next instances of widget with the same or different configuration onUpdate is not triggered.

This is the code: public class Vjezba5Activity extends Activity { TimerTask TimerTask11; Timer timer1 = new Timer(); /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final ToggleButton TB1 =

问题 I have a asynctask that I cancel when the view is destoried via onDestoryView(). This problem is I do "downloader.cancel(true);" and it wont cancel. In fact, it will return false. Currently, it references the ListAdapter to add items to it. However when I turn the screen to landscape, the ListAdapter is null during the onPostExecute. I cannot figure out when the ListAdapter becomes null. I have tried both onDestory and onDestoryView to cancel the asynctask before the ListAdapter becomes null

问题 I am trying to include a widget / view in my Android app that displays a number and when the number is incremented, the new number slides into view as if each digit was on a rolling dial.

问题 Ok, this is about to drive me nuts. I'm still a newbie (and maybe an idiot) but this one has had me running in circles. I'm trying to implement cursor control in an editText via soft buttons (left, right, up down). From what I've researched, it looks like I need the methods in the Selection object like moveUp(), moveLeft(), extendUp() etc. but they all need a "text.layout" object and I don't know how to get one. Am I on the right track? Help? 回答1: It sounds like you want to use a
