map

问题 I'm already first time using Map on java. I'm creating a project on the console where I create Strings with this structure: String = word1 word2 word3, code; //This code is a number, can be the same as the // Map's key. Then, each time I create a String like this, I save it into a Map. After creating and saving into the map one or more Strings, I have to be able to show them in the console, or to delete one of them. The problem I'm getting is that when adding one String to the map, is

问题 I would like to know how can I iterate in a 2Dimensional HashMap? I am creating an Object TrueStringMap2D that does the following: It will be a map 2D, i mean 2 keys and one value. But the iterator implemented here is not functional.. i didnt know how to redefine the Iterator method in TrueStringMap2D :S (if possible should be remove in the iterator() functional) Anyone can help? Thankyou very much!! 回答1: I'll reinterpret the question into something similar that I enjoy answering, and then

问题 I tried to set map center by method setCenter, but still not working. Map is not moving. I tried to used transform from projection to map projection and without successful. Here is part of code. Thanks. <script type="text/javascript"> var lon = 15.869378; //WGS LL84 var lat = 49.528964; var zoom = 5; var map, layer; function init(){ map = new OpenLayers.Map('map'); layer = new OpenLayers.Layer.TMS("Name", "[URL]", { 'type':'png', 'getURL':get_my_url }); map.addLayer(layer); var markers = new

问题 After a lot of research to resolve my issue, I have to ask. Everything is set up but the map won't show. The error is: 08-16 20:31:49.473: E/Google Maps Android API(10864): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors). I am running the Map on Debug mode (I've also tried by installing the .apk into the device and running it) and the same thing happens - no Map. I have checked Api key Manifest <?xml version="1

问题 I'm trying to figure out how to set every String and Key name from my app's SharedPreferences using the getAll() method so I can use those values to name populated buttons and assign those buttons to the access the proper string in sharedpreferences to display in a textview. The problem is I do not know how to save these values to a String or String Array because I haven't ever dealt with maps before. If anybody could help me store my SharedPreferences keys and string values to a String array
