I'm trying to create a my own way of selecting because I want to select across multiple edittexts. And selection might include other Views also (not just text).
I have so far found that the android.text.Selection class handles text selecting. As this class is a static (constructor private) class it ensures that in the application there is no way to create 2 or more selections simultaneously (because when you add a new selection,it has to be done through this class and this class removes the previous selection when adding a new one). Therefore there is no way to select text in multiple edittexts at the same time.
So I'm trying to create my own way of selecting (yes, manually add a backgroundColorSpan when user does what is done when selecting).
But how do I deal with the anchors? As android is open source I'd like it if I can find the class that handles selection anchors (in other words the class which determines when to call Selection class to extend selections to the next line based on how user drags the anchor.) So in which class does this happen exactly?
For anyone interested it's the,
android.widget.Editor class

I really have a hard time finding help on internet since no one is giving examples on how to implement codes in GUI formed app. So I have my interface created and whole app works through buttons. Every code I find is for just workspace line, or how would I call it. Now I want do the following:
I have an input page for registering members in the gym. When I register them, they go to jTable. Now, I want to make it possible to edit columns Weight and Instructor from the table. I saw how to add ComboBox into table column, but don't know how do it in GUI formed app, where table is not created by the code. And I want to edit Weight column with jTextField the same I would do with ComboBox for instructors.
The question can also be: How do I define these custom things in table (or any other object in GUI Java App) when I already have GUI table set on place with drag and drop in NetBeans?
I've one seen on an application for iPhone an interesting idea which consists of showing a list of options when we click on an area for text edition. For example, imagine I have a field called "City" (EditText) which I am suposed to enter the name of the city. When clicking on the EditText, a list automatically shows up with a few city suggestions (e.g. defined by the programmer) which can be selected. If the user doesn't like the suggestions, he writes the city himself and this city can be saved for this list for future.
I want to programme this on my App for android. I need that, when clicking on the EditText for introducing the data, a list automatically shows up with some suggestions defined by me (Programmer). However, I don't know how this can be done. I've googled but maybe it's hard to find the correct keywords to find a similar topic.
The idea is that the user should use the names already written in the list in 90% of the time and just write himself the new ones when it's necessary. Something like a dropdown list but with possibility of writing new stuff instantly without specific option.
How can this be achieved?

You can consider focus changed listener for Edittext,
when focus is gained you can show a context menu to choose data from.
Sorry, I'm kind of a beginner to GUI interfaces (well, a beginner to java, really), and I was wondering: How does one make a list of items that the user can add items to or remove items from, with the press of a + or - button?
What I really want (sorry if I'm being a little vague here) is one of those lists you sometimes see in application windows, which looks like a text box but cannot be typed in. Right now my application (it's a small app to organize the schedule of a hospital) just reads from a text file and writes to another text file. No GUI, no window, the user just writes a bunch of names in the text file, one per line, then runs the jar and opens the output file and the schedule is there. I want them to just be able to add or remove names from a list with buttons — adding a name by clicking 'plus' and typing the name, and removing a name by selecting the name and clicking 'minus'. I still, however, want it to save to a text file, so that the next time the user opens the app, all the names are still on the list.
Just to be clear, I don't want a list displaying the output (i.e. the names organized into a schedule), just one containing the input.
Thanks a lot for any help you can give.
You probably want a JList with a couple of JButton instances to add/remove items.

I'm trying to convert a drop down box widget into a SuggestionBox because the current drop down menu has 100+ choices. It seems like you can only add String suggestions to a SuggestOracle though. I need to be able to add a custom object that contains both a description and an ID that matches the record to the database though. Would I have to extend the SuggestOracle class?
Yes as i know you can not use pair of values i.e Id and Value. You have to add your strings in suggestion box perhaps you can use different solution other then suggestion box i.e. Create a List of values popup. And add as many fields as you like. display your data in flex table with pagination. update your form with the selected row by using selecition handler. for reference how to use FlexTable and handle events please see able Single Row Click Event
SuggestOracle is the parent class of MultiWordSuggestOracle which you are already yousing.
public class MultiWordSuggestOracle extends SuggestOracle
