I have a Spinner that is used to populate some choices. My Spinner acts as a filter to the ListView below it.
The Spinner looks something like this:
****Option 2**** (selected)
****Option 1****
****Option 2****
****Option 3****
****Option 4****
Is there a way that i can hide the selected item from the dropdown list, like in this case Option 2 which is selected shouldn't appear in the dropdown list
Android Spinner not providing any built in implementation which satisfy your requirement.
You need to modify the data set of your Spinner Adapter when user select any item.
Save the selected Item in separate variable and remove it from data set of your Spinner adapter. When user select any other item, you need to add already selected item to data set, save the newly selected item in global variable and remove it from data set of Spinner adapter.

Unfortunately, standard spinner doesn't allow to show 'nothing selected' state after adapter is set. As soon as you set adapter first element become selected.
You should create custrom spinner for "nothing selected" position. See here http://stackoverflow.com/a/12221309

I want to pre checked/ pre selected a specific item when a list being created. I use CheckedTextView for the text and checkbox.
For example, I have 3 items, after the list create, I will get a listview. and the second item is already check/tick.
I know how to perform it by using onclick, but what I need is before I click it. some item is already checked.
Thank you
Add a boolean isChecked variable in your ItemModel, set true/false as you wish. Check/uncheck item in your CustomAdapter.
How to show spinner drop down with only the items which is not currently selected like below images
Drop down list when spinner with FOLLOWING as current item is clicked
Drop down list when spinner with NEW as current item is clicked
There is no default setup for that usecase. You need the change the Data-Set of the SpinnerAdapter (Model) or change the Adapter used by your Spinner in the onItemSelected method and save the selected Item in a sparate variable. A Spinner always displays alle Items in from the Spinner Adapter. There is also not the option to add an emty cell.
I'm using the cool feature of the ListView to show a checkbox next to the item in the ListView.
I bind my list to an array of strings.
The onClick and onSelectedItem listeners get called fine, in this way I know the index of the "string" checked (or unchecked).
I'm storing all the checked strings into preferences (as a comma-concatenated-string), and everytime the activity becomes visible I would like to set the checked items back in the listview.
Is there a way of doing it? or the CHOICE_MODE_MULTIPLE doesn't allow to set the checked items?
note: I'm not using a custom view, since what I want to display is just a string and a checkbox. I've tried setSelection(index) but it should set the onlyone selected (highlighted) row.
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice,names);
m_playlists_list.setAdapter(adapter);
m_playlists_list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
Use the setItemChecked method of ListView
Sets the checked state of the specified position. The result is only valid if the choice mode has been set to CHOICE_MODE_SINGLE or CHOICE_MODE_MULTIPLE.
