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.

I want the element to display then remove but not show in next spinner list but not getting any solution.

You must have to call spinnerAdapter.notifyDataSetChanged(); or spinner.setAdapter(spinnerAdapter); after removing element from array, for next spinners.
I am using a Spinner and ArrayAdapter to populate items in Spinner. I want to make the spinner multi-selectable i.e. user can select multiple items and should also be able to deselect to none. My code is as below,
spnAdapter = new ArrayAdapter<String>(this,android.R.layout.select_dialog_multichoice,items);
spnAdapter.setDropDownViewResource(android.R.layout.simple_list_item_multiple_choice);
spnProducts.setAdapter(spnAdapter);
Here the items is an array list.
This code gives me a spinner with check boxes but it does not allow multiple selection. What should I do to make it multiple selection?
Thanks in advance.
I'm wondering if there's a setText() method in spinners? What I want to do is display the selected item in a spinner (it's saved via sharedpreferences.) so the next time, the user displays the saved data, it should display in the spinner. How can I do that? I already know how to do it an edittext like this : age.setText(age);
But wondering how to show it in spinners.
There is no such method in Spinner class.
You need to implement a SpinnerAdapter which will be responsible for creating the items of the Spinnerand attach it via the setAdapter() method.
The official Spinners guide may help you: http://developer.android.com/guide/topics/ui/controls/spinner.html
I have a problem that I have two spinners, second spinner is dependent on first (means when I select a item from 1st Spinner then according to that Second Spinner gets filled). But the problem is, I want Select Keyword as a default Item for both spinners, and when I will click on that, spinner should filled with parsed Info and when I will select an Item from first Spinner then the Parsing starts for Second Spinner but Spinner remains with default Select Keyword, when I will click on second spinner then it should be filled by the parsed Info.
How can I implement this, because when I am setting the adapter in any spinners its onItemSelectedListner first called, which is not desirable.
You will need to add "Select" as your first item in your array list..
and on click event of the Spinner you just remove the First item from your array list
you will also find many similar question in Stack Overflow..search for it and you will get your exact answers with example.
You Can do this by Dialog, make a Customize dialog with List Box and fill the list with parsed data after click on TextBox which contains Select Keyword as a default.
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.
