bounds

I am using Google Maps v2 in my application. When the user pans or zooms on the screen I would like to get the area of the map based on which I want to fetch the POI only in the screen view part. I went through the documentation but could not find any help. Pavel Dudka You need to use Projection and VisibleRegion classes in order to get visible LatLng region. So your code would look something like: LatLngBounds curScreen = googleMap.getProjection() .getVisibleRegion().latLngBounds; 来源： https://stackoverflow.com/questions/14700498/android-google-maps-get-boundary-co-ordinates

How to get bounds in degrees of google static map which has been returned, for example, for following request http://maps.googleapis.com/maps/api/staticmap?center=0.0,0.0&zoom=10&size=640x640&sensor=false As I know, full Earth map is 256x256 image. This means that n vertical pixels contain x degrees, but n horizontal pixels contain 2x degrees. Right? As google says center defines the center of the map, equidistant from all edges of the map. As I understood equidistant in pixels (or in degrees?). And each succeeding zoom level doubles the precision in both horizontal and vertical dimensions. So

This question already has an answer here: Looping through array and removing items, without breaking for loop 13 answers I have an array of elements and need to remove certain ones from it. The problem is that JavaScript doesn't seem to have a for each loop and if I use a for loop I run into problems with it basically trying to check elements beyond the bounds of the array, or missing elements in the array because the indexes change. Let me show you what I mean: var elements = [1, 5, 5, 3, 5, 2, 4]; for(var i = 0; i < elements.length; i++){ if(elements[i] == 5){ elements.splice(i, 1); } } The

This question already has an answer here: What is an IndexOutOfRangeException / ArgumentOutOfRangeException and how do I fix it? 4 answers I'm aware of what the issue is stating but I am confused to how my program is outputting a value that's outside of the array.. I have an array of ints which is 0 - 8 which means it can hold 9 ints, correct? I have an int which is checked to make sure the users input value is 1-9. I remove one from the integer (like so) if (posStatus[intUsersInput-1] == 0) //if pos is empty { posStatus[intUsersInput-1] += 1; }//set it to 1 then I input 9 myself and I get the

I would like to know how to use the UIView property clipsToBounds . The official documentation says the following: clipsToBounds property A Boolean value that determines whether subviews are confined to the bounds of the view. Discussion Setting this value to YES causes subviews to be clipped to the bounds of the receiver. If set to NO , subviews whose frames extend beyond the visible bounds of the receiver are not clipped. The default value is NO . But I'm unclear on what this means exactly. How should I be using clipsToBounds ? What are the consequences of setting this property to YES

I gather that you cannot bind a Java generics type parameter to a lower bound (i.e. using the super keyword). I was reading what the Angelika Langer Generics FAQ had to say on the subject . They say it basically comes down to a lower bound being useless ("not making any sense"). I'm not convinced. I can imagine a use for them to help you be more flexible to callers of a library method that produces a typed result. Imagine a method that created an array list of a user-specified size and filled it with the empty string. A simple declaration would be public static ArrayList<String>
