Android: Edittext with gravity center not working on device

由 回眸只為那壹抹淺笑 提交于 2019-12-18 02:37:16
问题 In Android I'm using a single line edittext with gravity set to center. In the Emulator this works great both the hint and a blinking cursor shows up. When testing on device (Xperia X10) neither the hint text nor the blinking cursor shows up. The blinking cursor only shows if I enter some text into the edittext. This is my edittext, can anyone see if something is missing? <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android

Custom cursor interaction point - CSS / JQuery

由 Deadly 提交于 2019-12-17 22:46:37
问题 I'm trying to use a custom cursor for an online game, in this case it's a sniper scope. The problem is when I reference the cursor via CSS, the interaction point is still the top left of the icon, whereas it needs to be dead center of the icon for the cursor to make any sense. Here's the cursor: cursor:url(http://www.seancannon.com/_test/sniper-scope.cur),default; Here's a demo: http://jsfiddle.net/9kNyF/ If you put the red dot from the cursor over the red dot I created in the demo, it won't

When are TSQL Cursors the best or only option?

由 风流意气都作罢 提交于 2019-12-17 19:18:36
问题 I'm having this argument about using Cursors in TSQL recently... First of all, I'm not a cheerleader in the debate. But every time someone says cursor , there's always some knucklehead (or 50) who pounce with the obligatory 'cursors are evil' mantra. I know SQL-Server was optimized for set-based operations, and maybe cursors truly ARE evil incarnate, but if I wanted to put some objective thought behind that... Here's where my mind is going: 1) Is the only difference between cursors and set

How to get caret position within contenteditable div with html child elements?

由 可紊 提交于 2019-12-17 18:58:42
问题 I am working with a contenteditable div that will have the option to have inline html elements such as tags in the text flow. At certain points I need to grab the caret position but have found that with the example code the position returned is incorrect if the caret is after an html child element. I need a cross browser solution that will allow me to store the position of the caret so that it can be restored a split second later even with the presence of html elements in the text flow.

Android how to query huge database in android (cursor size is limited to 1MB)

由 孤街醉人 提交于 2019-12-17 18:52:53
问题 I'm working to develop an application that has to query at some time, a database with over 4k rows, and each row has 90 fields (Strings). The problem is that if I select * from database, my cursor gets really big (over 4MB). And the cursor in android is limited to 1MB. How can I solve this, or what's the most elegant method to workaround this? It is possible to split database in smaller chunks and query them out? Thanks, Arkde 回答1: I found a way to handle this and I want to share with all who

How can I get position of cursor in terminal?

由 a 夏天 提交于 2019-12-17 18:29:11
问题 I know I may save position using tput sc , but how can I read it's position to the variable? I need the number of row. I don't want to use curses/ncurses. 回答1: At ANSI compatible terminals, printing the sequence ESC[6n will report the cursor position to the application as (as though typed at the keyboard) ESC[n;mR , where n is the row and m is the column. Example: ~$ echo -e "\033[6n" EDITED: You should make sure you are reading the keyboard input. The terminal will "type" just the ESC[n;mR
