问题 I'm trying to get my spinner working as the Action Bar Drop Down List item, but I cant seem to implement it at all, there aren't many tutorials for this after searching through Google.

问题 I deal with numeric data that is often edited up or down by 0.01*Value_of_variable, so a spinner looks like a good choice compared to a usual text cell. I've looked at DefaultCellEditor but it will only take text fields, combo boxes or check boxes. Is there a convenient way to use a spinner? 回答1: ... and overwrite the getCellEditorValue() method: class SpinnerEditor extends DefaultCellEditor { private JSpinner spinner; public SpinnerEditor() { super( new JTextField() ); spinner = new JSpinner

问题 I can successfully push only next view in my iPhone app. However, cause the next view retrieves data to populate the UITableViews , sometimes waiting time could be a few seconds or slightly longer depending on connection. During this time, the user may think the app has frozen etc. So, to counter this problem, I think implementing UIActivityIndicators would be a good way to let the user know that the app is working. Can someone tell me where I could implement this? Thanks. pushDetailView

问题 I have created a spinner which is automatically updated with appliance names when a person adds an appliance using an array adapter. I created an OnItemSelected method with the spinner so when one of the names in the spinner is selected, a new window appears. However the OnItemSelected is automatically selecting the first item on the list when the activity starts and so the user does not have a chance to actually make a selection until the new window appears. Here is the code: public void

问题 I'm trying to use the latest version of the jquery.ui.spinner.js . http://wiki.jqueryui.com/w/page/12138077/Spinner The spinners are showing-up and updating the textboxes, but I'm having trouble figuring out how to capture the 'change' event.

How can I do this? 回答1: What do you mean by id. You can use ArrayAdapter to populate the Spinner. When item is selected just get the element from the adapter and save the data you want. Spinner spinner = (Spinner) findViewById(R.id.spinner); ArrayAdapter<MyObject> adapter =
