I'm going to try and explain what I want to achieve. So I currently have a customlistviewadapter, each row can have a different view. The user will then click on any row to change the value of that specific row. When the user clicks on a row, then an alert dialog pops up where the content of that row can be changed, when "Ok" is pressed the new value is saved.
Here is the code:
// Inflate correct layout & populate variables
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
List_Entry varStrings = getItem(position);
Button write_btn;
LayoutInflater layoutInflater = LayoutInflater.from(context);
switch (getItemViewType(position)) {

The problem I have is that some rows contain a spinner, and because I have an OnclickListener on any row, I had to make all spinners nonclickable. otherwise, the spinner could be clicked or the row where the spinner is located can also be clicked which will bring the alert dialog up. So to avoid confusion for the user I disabled the ability to click on a spinner (See inside "case SPINNER_LAYOUT").
The problem is that my boss does not like the grayed-out look of the spinners (It looks like it's non-selectable).
So what I want to do now is to make the spinners selectable in the listview and prevent the user to select that specific row that contains the spinner, this way the spinner will be the normal black (not grayed out). Then I want to create an onItemSelectListener to handle the clicks on spinners.
So Im not sure where to add the OnItemSelectListeners.
Inside the case containing the spinners?
- "case SPINNER_LAYOUT:"
- "case SPIN_CHECK_LAYOUT:"
- "case SPIN_CHECK_STAT_LAYOUT:" If I add the OnItemSelectListeners inside the case structures, then multiple OnItemSelectListeners will be created as many as there are spinners in the listview.
Outside the switch structure, but this I'm not sure how to do because each spinner is defined inside the case structure and can't be used outside of it.
Here is how the listview looks, the rows containing "VL frequency" and "System type" has a spinner in. (I enabled the spinner selection when I took this screenshot, so it's not grayed out in this image). 
This is the alert dialog that comes up when the user clicks on any row that contains data.
So I basically need help on how and where to place the setOnItemSelectedListener for the spinners in the customListviewAdapter.
Hope this makes sense. Marinus
