问题 i'm having a problem with a Cursor and a SimpleCursorAdapter. What i want to accomplish: I have a database with 3 fields _id | nickName | somethingelse I want to select all nickNames distinctly and provide them in an AutoCompleteTextView.

问题 Is it possible to resize a CSS mouse cursor that uses a custom image URL? For example: cursor: 'url(resources/images/custom-cursor.png), auto'; The image is too big, and I haven't been able to find a way to style it past setting the image URL. I know I can just save the image with a new size, but I'd rather set the size on the client if possible. 回答1: Checked it, I guess it is not possible to natively change the cursor's size. One thing you can do is to hide the cursor using the following

问题 I have a Spinner that's populated using a cursor containing data from a database. It appears that it's impossible to set the selected item in the spinner using the value of the ID column of a row. And that the only way to set the selected item is by using the position of the row within the dataset. Is this correct? If so, is there a more efficient way of determining the row's position than by iterating through the dataset using the cursor? The inefficient (to my mind) way is outlined here.

问题 All, Just a beginner to Programming. I was exploring on the java Collections and Iterator and I would like to know how the cursor is used for iterating the collections. public class Collections { public void myFun() { int i=0; List<String> listObj = new ArrayList<String>(); listObj.add("Hello"); Iterator<String> itr = listObj.iterator(); while(itr.hasNext()) { String s=(String)itr.next(); System.out.println(" List Elements are : " +s); } } public static void main(String[] args) { Collections

问题 In my java application, i m trying to change the mouse cursor with an argb 32bit bmp file with transparency.

问题 I got a song id from a playlist in MediaStore, using long id = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Playlists.Members.AUDIO_ID)); and the id is correct, but as the only other data available is CONTENT_DIRECTORY, DEFAULT_SORT_ORDER, PLAYLIST_ID, PLAY_ORDER, and _ID, I am not sure how to get the important parts of the song. I need the title, album, artist, etc., as if I was going through MediaStore.Audio.Media to get Song info. I found an answer that I tried to modify to fit my

问题 I know how to set the cursor to a specific point in the console with SetCursorPosition or CursorLeft and CursorTop together. That's not a problem. But , how can I get the value of that point? Isn't there a thing like Console.Cursor ? So I can get the character at that position? Maybe something like: char c = Console.GetCharAtCursor(); No luck? 回答1: AFAIK, you have to read the entire console buffer as a two dimensional buffer, and use the cursor's X and Y coordinates as an index into that
