Android : Creating GUI programmatically at run time in java

I have to create number of buttons and textbox, etc. depending upon a certain number. For ex: if the number = 5, I need to create 5 buttons, and if its value is 10, I need to create 10 buttons.
To achieve such a functionality, the conventional xml GUI won't make it up. I need to develop the GUI dynamically. How can I do that?

Take a look at RecyclerView. You need to apply the DataSet (what u receive dynamclly) and then let the Adapter handle all of the Binding.
Take a look at this tutorial, there are many more.
Notice that you will need to create TWO Viewholder (button and a textview) and override the getItemViewType

Add a Linear/Relative layout in xml and on run time according to given number add view(buttons and text views) in this layout.

Combine javafx 2 ListView and GridPane features

My target is to display an abbreviation list with two entries per line: the abbreviation and the corresponding long version. For a nice layout I used a GridPane because of the vertical alignment over all entries - it's nice to read.
But I also want to scroll to the clicked abbreviation and set the focus on it like in a ListView version of it.
For example the # on page links in good old HTML. Is there another javafx layout element I miss to achieve this?

I don't believe there is a provided control that will work for the specific scenario you are describing. However, I think one of these options might work for you...
Use the TableView control and add two columns for the information you want to show (one for the abbreviation and another for the long version). TableViews also have the scrollTo and setFocus functionality you're looking for. Here is a good resource to get you started with the Tableview control. You can also style the Tableview with CSS to look less like a table and more like a list if thats what your intention is.
The second option is to set a custom cell factory on your ListView that builds custom cells using HBoxes, VBoxes, Labels, etc. to achieve your desired look. You would also want to use the cell factory to populate each ListView cell with an object that contains both the abbreviated text and long version text. A couple good resources, 1, 2
Although I think both option will work fine, I would suggest option 1 since in option 2 you are sort of building a table type structure anyway. I hope this is helpful!

Android - Help needed with designing a screen with either table layout or list views

I am currently developing an Android app that is to be a counterpart to its sister iPhone prototype.
My task is to recreate the screen from a design mockup from the iPhone app in Android, as shown here:
What would be the best layouts / views to use for replicating this screen in an activity?
Thanks.

Your question does not clear some things up. Also, I disagree with Ted Hopp's answer. I believe he is assuming that the medications will be filled statically, or something like that.
By the looks of your app, I assume you will be filling stuff dynamically, probably with many medications at once, or no medication at all. By the arrows in the iPhone mock-up, I also assume you will want to perform actions depending on the medication selected.
All that said, I would use a ListView. My general concept (the one I'd probably use) would be like this:
You have your data source, and use a Loader/LoaderManager/etc. to fill that into a Cursor. I'd feed this cursor to a CursorAdapter (perhaps a SimpleCursorAdapter, which seems likely and easy by looking at that UI concept --- won't need to customize the adapter part itself). Finally, this adapter would be used in the ListView. This is fairly easy and won't take much code (the ListView-SimpleCursorAdapter-Cursor stuff, the data logic is certainly custom).
You can then manage each of your clicks using the proper ListView listeners, IIRC. And act accordingly depending on the item selected. I'm guessing that the user would, for example, startActivity to see a detail about each medication.
However, as I said, if you have a fixed number of medications (here says an experienced former leukemia patient here, so I always assume medications vary widely!), a single TableLayout would do, but I feel that's not the case.
Ah, and about the layout for each component/med, as I said, a simple layout would do. Probably a LinearLayout with horizontal orientation. Again, very simple to implement with a SimpleCursorAdapter.

There's a nice example of how to do this with a custom row view here. This is probably the cleanest way to go.
The closest built-in widget for this is a TableLayout. Take a look at the Hello Views tutorial project for an example of this in action. You might want to wrap it in a ScrollView.

The right approach is highly dependent on the requirements. As I see it, you have (at least) a few options:
TableLayout
ListView
Something custom
As David noted, the TableLayout is most appropriate if you have a fixed set of data, but you can make it work dynamically too simply by adding child views. The benefit of using the TableLayout is mainly a built-in implementation of columns, including dynamic column sizing based on contents. The down-side is the lack of built-in dynamic support, especially when working with large data sets.
A ListView is a better fit for dynamic and large data sets, but comes with the limitation of not supporting columns. Ted's link lets you simulate columns, but unlike TableLayout these columns have a fixed width (in percentage of the parent's width). The columns are not sized based on content. You could potentially try to do something to measure all the children, but it'd be tricky. It can also be mildly annoying to try to deal with headers in a ListView, though with a little searching you'll find plenty of resources to help you with this.
The third option is to roll your own AdapterView or AbsListView. Of course this involves a significant amount more work, but you could take a look at how TableLayout works and resize the columns based on the content. This would also get you support for adapters and all the benefits that come along with that. This is probably quite a bit of work though, especially resizing the columns based on content.
Consider whether your columns must resize to fit their content or not.

Overlapping tabs in Java

I had design 5 tabs using Swing. Each tab contains 2 or 3 sub tabs. Now the problem is, at run time the text fields in tabs are overlapping. I use the method
refreshI18NText(jPanelReceivedForm1A)
to refresh the jpanel.
but still I'm getting the problem.

You need to make sure you are using the correct layout manager. The Oracle tutorial is useful for selecting and explaining each layout manager.

Question about creating GUIS "dynamically" on Android

I'm trying to make an android app (I'm new in the Android programming world), and I'm having problems creating the GUI.
The point is that I get information of some data that is divided in days... The problem is that I don't know, until I retrieve the information, how many days the GUI should display.
http://img574.imageshack.us/img574/3787/mainscreen.jpg
The grey part will be a TextView, and, also, the black part will be another TextView with multiple lines.
So, the point is, how can I do to have multiple TextView's without knowing before the exact number? I suppose that I can't declare them in the layout.xml
The only solution that I've been thinking about is to create in the layout 7 pairs of TextView and, when I know the exact number, just use what I have to, and don't use the others... (It's a bad solution)
What do you suggest?
Thank you for your answers!

You should create a ListView, which inflates TextView for the items you have.
You can use this example of how to create sectioned ListView, which will look exactly like you want.

I'm not familiar with Android, so other people may offer better, more specific advice.
In the environments I'm familiar with, the problem of displaying an unknown number of items is solved by using not a series of display elements for each data item but a list control. The list component will display as many items as you give it, and can usually be modified to have different appearance for different data, so you're flexible in making it as pretty as you want.

Well you can consider this one also,
Create a table layout in XML, give it a id: TableLayout table=(TableLayout)findViewById(r.id. ....)
Create dynamic TextViews using: TextView day=new TextView(this); day.setText(day name);
Now add this text view to your table layout : table.addView(day);
Run the code for textView creation and addition to table in loop
Hope this helps...............
