I am a very frustrated newbee! I really don’t know where to start. I have an app based on the one in the dummies book. Got it working. Then tried to convert it to use the WIMMOne dialogs for time and date. After a bunch of false starts I loaded one of their samples and got it working. I then isolated the code in that and pasted in my sample. I cannot get past errors. (It doesn’t help that eclipse constantly adds some of its own. Sometimes I load the source and all statements, including imports, are marked as errors, sometimes I get the R.id,— in error, I have even had it marked comments as in error.<\/p>\n
However, I have cleaned it and reloaded it enough times that I think I am down to a few real errors.<\/p>\n
There are a couple basic differences between mine and the sample code: The sample is one big activity java file, mine is in a fragment. Mine had a separate java file for the time dialog. The sample was in the one file, so I coded mine that way. Mine has two menus, a list from which the user goes to a “detail” menu. The sample is all one screen.<\/p>\n
There were 2 JAR files from WIMM, I have both in my libs.<\/p>\n
To save space I included the first part, where I am getting 3 errors, but will be happy to provide it all if needed.<\/p>\n
The first is the sample. It works and even with my commented code, there are no compile errors: Thanks,Clark<\/p>\n

You are copying code that was being used in an Activity<\/code> and using it in a Fragment<\/code>.<\/p>\nThis will require some modification.<\/p>\n

In a Fragment<\/code>, to set the layout and find views we override onCreateView()<\/code>:<\/p>\n@Override\npublic View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){\n View v = inflater.inflate(R.layout.reminder_edit, null);\n mTimeButton = (Button) v.findViewById(R.id.reminder_time); \n return v;\n}\n<\/code><\/pre>\nTimePickerDialog myTimerHandler = new TimePickerDialog(this);\n<\/code><\/pre>\nThe argument of the TimePickerDialog<\/code> constructor is a Context<\/code> object.

This is mainly an attempt to explain what the compilation errors mean<\/em>.<\/p>\n\nERROR: The method setContentView(int) is undefined for the type ReminderEditFragment<\/p>\n<\/blockquote>\n
You are calling a setContentView<\/code> method on ReminderEditFragment<\/code>, but ReminderEditFragment<\/code> has no such method.<\/p>\nIt appears that you are trying to call Activity.setContentView<\/code> on this<\/code>. But this<\/code> is not an Activity<\/code> … because of your refactoring.<\/p>\n\nERROR: The method findViewById(int) is undefined for the type ReminderEditFragment<\/p>\n<\/blockquote>\n
Same as above, for a different Activity<\/code> method.<\/p>\n(I’m not an Android expert, but it seems that you are doing things on a Fragment that you should be doing on an Activity. Perhaps, your Fragment class needs a reference to some Activity instance that it can use for those calls … ?)<\/p>\n
\nERROR: The constructor TimePickerDialog(ReminderEditFragment) is undefined<\/p>\n<\/blockquote>\n
The standard TimePickerDialog<\/code> class has 2 constructors, but neither of them take a single ReminderEditFragment<\/code> argument. You need to look at the TimePickerDialog<\/code> javadoc …<\/p>\n<\/li>\n- \n
1) Don’t run your app, when active XML file.
\nIf you did it, clean project and remove generated file<\/p>\n
2) ?lways save project Ctrl + Shift + S<\/code> after adding widgets to layout. After saving will generated an addresses of this widgets and will have no problem with
