Android: How to Disable List Items on List Creation

Android: How to disable list items on list creation

In order to disable list items on list creation you have to subclass from ArrayAdapter. You have to override the following methods: isEnabled(int position) and areAllItemsEnabled(). In former you return true or false depending is list item at given position enabled or not. In latter you return false.

If you want to use createFromResource() you will have to implement that method as well, since the ArrayAdapter.createFromResource() still instantiates ArrayAdapter instead of your own adapter.

Finally, the code would look something like the following:

class MenuAdapter extends ArrayAdapter<CharSequence> {

    public MenuAdapter(
            Context context, int textViewResId, CharSequence[] strings) {
        super(context, textViewResId, strings);
    }

    public static MenuAdapter createFromResource(
            Context context, int textArrayResId, int textViewResId) {

        Resources      resources = context.getResources();
        CharSequence[] strings   = resources.getTextArray(textArrayResId);

        return new MenuAdapter(context, textViewResId, strings);
    }

    public boolean areAllItemsEnabled() {
        return false;
    }

    public boolean isEnabled(int position) {
        // return false if position == position you want to disable
    }
}

How to disable the particular list item in list-view in android?

try using this code in setOnItemClicklistener()

if(listview.getChildAt(selectedPosition).isEnabled())
{
    listview.getChildAt(selectedPosition).setEnabled(false);
}

How to disable list view item based on string value?

You'd have to use the item availability directly in isEnabled(int).

new FirebaseListAdapter<BookingTimes>(options)
{
    ...

    @Override
    public boolean isEnabled(int position)
    {
        return getItem(position).getAvailability().equals("Unavailable");
    }
}

Also keep in mind that FirebaseListAdapter has a generic parameter type. Also make sure to not views like timeTextV or availabilityTextv, preferably with the view holder pattern.

You can set enabled state in your adapter.

rowView.setEnabled(false)

How to disable previous items in a ListView

You can do this as below mentioned -:

You need to store the position of clicked button was. So initialize a variable in your class

int mButtonSelected = -1;

EDIT 1.

Then make a change to your isEnabled method

 @Override
public boolean isEnabled(int position) {
    if(position<mButtonSelected){
        return false;
    }
    return true;
}

That will work it if any other button was clicked. but you have to do that in your onClick

mButtonSelected = position;
notifyDataSetChanged();

Let me it worked or not

EDIT

see below changes in your code-:

public class SelectStnListByRoute extends BaseAdapter {
Context context;
ArrayList<StnNames> stnList;
LayoutInflater layoutInflater = null;
ViewHolder viewHolder;
private int mLastClicked;
private SQLiteDB sqLiteDB;

int mDepartSelected = -1;

    super();

    sqLiteDB = new SQLiteDB(context);

@Override

    return stnList.size();

How to disable items in a List View?

Make your own subclass of ArrayAdapter that has AreAllItemsEnabled() return false, and define isEnabled(int position) to return true/false for a given item in your data set.
