问题 I have developed a re-sizable app-widget for tablets. The app-widget works nice on most devices with the majority of launchers, however there are some problems with the orientation especially on the GO-HD Launcher in portrait mode. The height of the app-widget is too big and doesn't look nice.

问题 I'm trying to figure out how I can disable the update period on my widgets? I don't need this particular feature.

问题 Let's say that I have a layout that contains <ImageView android:id="@+id/my_id" android:layout_width="123px" android:layout_height="345px" android:padding="0dip" android:scaleType="fitXY" /> which is used in an AppWidget and is set via a RemoteViews.

问题 I am new to Android applications and hence have a few questions. Using the code below, I am trying action on ImageButton.
