How to get the user selection from startActivityForResult(Intent.createChooser(fileIntent, “Open file using…”), APP_PICKED);?

问题 Is there any way to get programmatically the user selection after startActivityForResult(Intent.createChooser(fileIntent, "Open file using..."), APP_PICKED); or startActivity(Intent.createChooser(fileIntent, "Open file using...")); I do not want to start the selected application - I only want to know which one is it? Thanks! 回答1: No, you cannot find out what the user chose. You can, however, use PackageManager and queryIntentActivities() to make your own chooser. 来源： https://stackoverflow.com

问题 I'm looking for a way to set a selection in a textarea in Internet Explorer. In other browsers, this works just fine: textarea.selectionStart = start; textarea.selectionEnd = end; In IE, I assume I have to use createRange and adjust the selection somehow, but I cannot figure out how. Extra bonus points for a link to a proper documentation about createRange and associated methods, MSDN isn't helping out much. 回答1: This works for me: <textarea id="lol">

Android Spinner selection

问题 The OnItemSelectedListener event handler gets called both when a spinner selection is changed programmatically, and when a user physically clicks the spinner control. Is is possible to determine if an event was triggered by a user selection somehow? Or is there another way to handle spinner user selections? 回答1: To workaround you need to remember the last selected position. Then inside of your spinner listener compare the last selected position with the new one. If they are different, then
