Android spinners populate with data

I have three spinners in my activity. based on the item selected in first spinner the second spinner is populated with a new set of values. till here the program works fine. now i want that based on selection of item on 2nd spinner the third spinner should be populated. but i am not able to achieve this.

As you can do on the first spinner and second spinner. use secondSpinner.setOnItemSelectedListener(new OnItemSelectedListener() and then create and setAdapter to the third spinner.

How to get seleceted items from a listView

I'm trying to find a way to add a checkBox to a ListView layout that can be used to allow the user to select items to be processed. The listview is populated using a cursor via a SimpleCursorAdapter. Can anyone point in the direction on documentation describing how to do such a thing.

You need to manage the selected items in the listview in the getView method manually. At last you will get the selected items. use Arraylist or hashmap as per your need and comfort.
Hope it will help you.

Android spinner layout

I have set a dynamic value in a spinner . I am using following code for the same.
spinner_generalbooks.setAdapter(new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"}));
It is working fine, but I have a problem with the view of the spinner . If we select simple_spinner_item, it is ok in normal state, but when we want to change it, the rows are very narrow and not CheckedTextView whereas in normal spinner options comes with CheckedTextView. If we select simple_spinner_dropdown_item, the options come with CheckedTextView, but in normal state, it looks different as in the pic
(First one is default spinner and second one is using simple_spinner_dropdown_item).
I want to show the spinner just like as default spinner. How to make it?

Android will take the layout specified in the adapter and use it for the control and the items unless you specify the view-resource separately. The way through this is to set the layout to simple_item in the ArrayAdapter constructor and then set the layout dropdown_item separately in a call to setDropDownViewResource().
ArrayAdapter newAdapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"});
newAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_generalbooks.setAdapter(newAdapter);

If you whant to customize the visual of your Spinner, it'll be more simple to create your own component. A spinner is just a Layout that contains text, image and that display a list in a popup. Create a custom layout for your item and use a new BaseAdapter object to bind your datas.

Android Spinner Control - Presetting an item as being selected

My spinner control is displaying fine no problem. When someone is in create mode they are able to selected a value which I am able to record and store in my database.
But I have a problem when someone is in edit mode and I want to display the list but have one of the items (say the third) selected. I can't see how to do that. All the tutorials talk about how to populate the spinner but not how to preset one as being selected.
this.ddlCategory = (Spinner)this.findViewById(R.id.add_edit_place_ddlCategory);
ArrayAdapter adpt = new ArrayAdapter(this, android.R.layout.simple_spinner_item, categories);
adpt.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
this.ddlCategory.setAdapter(adpt);
Please help

You can use one of the setSelection methods to programatically select a value.
