How to implement add item in spinner array adapter in android?

ArrayAdapter is already based on List, so you don't need to make a custom adapter just to use List. However, it uses the List or array it's created with. It doesn't copy the elements into a new List.

If you give it a fixed-length array, then you can't add or remove members Create a List to pass to the constructor. Note that a List created from Arrays.asList() won't work because that is just a representation of the original array spinner = (Spinner)this. FindViewById(R.id.

DynamicSpinner); CharSequence itemArray = getResources(). GetTextArray(R.array. Simple_from_length); List itemList = new ArrayList(Arrays.

AsList(itemArray)); adapter = new ArrayAdapter(this, android.R.layout. Simple_spinner_item, itemList); adapter. SetDropDownViewResource(android.R.layout.

Simple_spinner_dropdown_item); spinner. SetAdapter(adapter) You could also use a List and getResources.getStringArray(), or whatever is convenient.

List itemList = new ArrayList(itemArray);this statement not executed itemArray not supported in list – narasimha Feb 28 at 6:43 @narasimha: Sorry. The ArrayList needs a List argument, not an array. Edited to correct.

You may use add method like below.. m_adapterForSpinner = new ArrayAdapter(this, android.R.layout. Simple_spinner_item); m_adapterForSpinner. SetDropDownViewResource(android.R.layout.

Simple_spinner_dropdown_item); m_myDynamicSpinner. SetAdapter(m_adapterForSpinner); m_adapterForSpinner. Add("dummy item"); //////////////////////////////////////////////////////////////// addButton.

SetOnTouchListener(new OnTouchListener(){ public boolean onTouch(View v, MotionEvent event) { final Dialog dialog=new Dialog(roughact. This); dialog. SetContentView(R.layout.

Dialog); dialog. SetTitle("Enter The Item"); dialog. SetCanceledOnTouchOutside(true); final EditText filename=(EditText)dialog.

FindViewById(R.id. Filename); filename. SetText(""); Button d_ok=(Button)dialog.

FindViewById(R.id. D_ok); Button d_cancel=(Button)dialog. FindViewById(R.id.

D_cancel); d_ok. SetOnTouchListener(new OnTouchListener(){ public boolean onTouch(View v,MotionEvent me){ CharSequence textHolder = "" + filename.getText(); m_adapterForSpinner. Add(textHolder); dialog.dismiss(); return false; } }); d_cancel.

SetOnTouchListener(new OnTouchListener(){ public boolean onTouch(View v,MotionEvent me){ dialog.dismiss(); return false; } }); dialog.show(); return false; } Try this..It will help u.

You'll need to create a custom Adapter, that will probably be based on List, and implement the add method yourself. In the add method, you'll need to add to the adapter's internal list of items (strings) The result of createFromResource is based on CharSequence, which is returned with a fixed size and is not increased dynamically.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
