I am creating spinner dynamically as user enter value in textField.
If user enter three then three spinner get created and all these spinner use same array.
If user select one value of spinner then these value will be deducted from other spinner list
I use onItemStateChangeListener but problem is that when i remove value from array then other spinner has also use same array so changes are reflected in all spinner so i am not geting desire output .
I want the element to display then remove but not show in next spinner list but not getting any solution.
how can i overcome these problem,please help me
You must have to call spinnerAdapter.notifyDataSetChanged(); or spinner.setAdapter(spinnerAdapter); after removing element from array, for next spinners.

I want to add data in spinner dynamically.
Like I have 3 spinners. Data of first spinner is fixed.
Depending on data selection from spinner 1 the data of second spinner will be fixed. And depending on selected data from spinner 2, the data of 3rd spinner will be fixed.
And I want to get data from string-array. How to add this?
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.
see this question might help
how do I set the spinner value to null or to a hint when it is not on click..? Because when I set spinner's adapter it appears in the spinner textfield even Im not selecting a specific dropdown item.
You can insert first item with "" (empty string) value in your ArrayList or Array.
If there is any data in the adapter in the spinner then it will show that data. So in this case it is not possible to show empty spinner.
In your case My suggestion is, use a entry like none/no selection in your spinner at the very first index. So that it will automatically show that. Also user can select no selection option from the spinner also.
Possible duplicate.
You could create the illusion of the spinner by styling a button like below.
android:background="#android:drawable/btn_dropdown"
see [here] for alternatives. (Android: Spinner hint)
On the onItemSelected:
((TextView)view).setText(null);
By using this, Spinner will not show any default value.
I am trying to make a form with 2 spinners, I want the content of the second spinner to be determined by the value of the first spinner. This would entail a runtime determination of a spinners content whereas I am used to declaring the spinner contents using array adapters.
How do I set the adapter for spinner 2 only after user has chosen value for spinner 1???
Thanks
To resolve this, you can have a data source array:
Initialize with empty, and set this array to adapter data source.
on Selection of first spinner, reset the data source array according to new selection and invoke notifyDataSetChanged() method.
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.
