cursor

问题 I've updated my device to Android ICS (4.0.3) I have an activity which contains a list view filled in with data read from a database. The data are arranged in the listview using an extension of the ResourceCursorAdapter. Once the list has been loaded and shown on the screen I've pressed the home screen in order to bring up the home screen. Then I've recovered my application from the recents (long pressing the home screen) and suddenly I got the following exception: 05-10 15:49:17.925: E

问题 I know that's a mouthful in the title, but here's what's happening... I'm using Eric Martin's SimpleModal plugin in my project. When a modal popup is shown, I want to show the cursor as busy, not on the popup itself but on the overlay for the background. This is fine; it works, I added cursor:wait to the overlay div's CSS, and I don't to talk about why I shouldn't use the busy cursor. The popup is shown when a webserive call beings and closes after some work is done (waiting for a webservice

问题 I want to be able to see the cursor all the time. No blinking, and no hiding. I could extend editText and get into rendering a graphic and of-setting it as the text is written but this is just a pain and will need redundant work to recognise user taps / cursor moves. To be clear editText.setCursorVisible(false); Is not the answer I am looking for. Possibly it could be set in the XMl drawable file? <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res

问题 I want to have an insert tab button for my UITextView so that users be able to insert a tab at beginning of the current line. No matter where the cursor is in the line, the tab should be inserted at the beginning of the line, and after that the cursor must go to the end of the line. Is it possible ? 回答1: I have no luck with positionFromPosition:inDirection:offset: and characterRangeByExtendingPosition:inDirection: . But this works fine for me: UITextRange *range = [textView selectedTextRange]

问题 Cursor.requery() is a very common method while using it to refresh a ListView's content. But why is this method marked "deprecated"? I can't understand the reason on the API docs very clearly. Cursor.requery() API: http://developer.android.com/reference/android/database/Cursor.html#requery() Can anyone please explain the reason any further? Thanks:) 回答1: I believe it was done because new Loaders API was introduced to simplify querying Cursors asynchronously. As deprecation note says Don't use

问题 im trying to set a cursor. the width and the height of the cursor is bigger than 32 px. but it just scale it down to 32px when i set it. any idea? 回答1: If you're using the LoadCursor function, then I think you'll always get scaled to the standard size. Try using LoadImage with IMAGE_CURSOR , a desired size of (0,0), and do not use the LR_DEFAULTSIZE flag. 来源： https://stackoverflow.com/questions/3560710/c-set-cursor-size-over-32

问题 I'm dynamically changing a cursor to a local svg on hover with $(element).on('mouseover', function () { $(this).css('cursor', 'url(svgs/pointer.svg) 9 30 auto'); }; Thats working fine but I'd like to select that svg to manipulate its fill color. Is there any way to do this so I don't have to make a bunch of different svgs with different fills? Thanks 回答1: You can use inline SVG. Just open your SVG file with your text editor. Copy the XML and use it instead. Just change the fill value and
