Disable Checkbox items in alertDialog

Question

I am giving array to select multiple options through alert dialog I want to disable selection if array is full

I have been able to stop adding items to array after it reaches the limit but not able to disable the checkboxes

 AlertDialog.Builder builder=new AlertDialog.Builder(this);
 View view=inflater.inflate(R.layout.dialog_genre,null,false);
 builder.setView(view).setTitle("Select Genres");

 builder.setMultiChoiceItems(array, checkedGenres, new DialogInterface.OnMultiChoiceClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which, boolean isChecked) {
            if(isChecked) {
                if (!selectedgenre.contains(String.valueOf(which)))
                    if(selectedgenre.size()<5)
                {
                    selectedgenre.add(String.valueOf(which));
                    checkedGenres[which]=true;
                }
                else{
                        Toast.makeText(getApplicationContext(),"you can't add more genres",Toast.LENGTH_LONG).show();
                    }
            }
            else if (selectedgenre.contains(String.valueOf(which)))
            {
             selectedgenre.remove(String.valueOf(which));
             checkedGenres[which]=false;
        }
    }
}

Views inside a ListView are reusable, so items aren't really linked to a view. You can however enable or disable a view when it's being added to the ListView inside your AlertDialog's ListView. ViewGroup.setOnHierarchyChangeListener lets you to do so.

    final CharSequence[] items = new CharSequence[]
            {"9×19mm Sidearm", ".40 Dual Elites", "228 Compact", "Night Hawk .50C"};
    boolean[] checkedItems = new boolean[]{false, false, true, true};
    final boolean[] disabledItems = new boolean[]{false, true, false, true};

    Context context = this;
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(context);
    dialogBuilder.setTitle("Select your pistol");

    dialogBuilder.setMultiChoiceItems(items, checkedItems,
            new DialogInterface.OnMultiChoiceClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i, boolean checked) { 

        }
    });

    AlertDialog alertDialog = dialogBuilder.create();
    alertDialog.getListView().setOnHierarchyChangeListener(
            new ViewGroup.OnHierarchyChangeListener() {
        @Override
        public void onChildViewAdded(View parent, View child) {
            CharSequence text = ((AppCompatCheckedTextView)child).getText();
            int itemIndex = Arrays.asList(items).indexOf(text);
            child.setEnabled(disabledItems[itemIndex]);
        }

        @Override
        public void onChildViewRemoved(View view, View view1) {
        }
    });

    alertDialog.show();

Note that setEnable won't avoid clickListeners to trigger. If you don't want to get your checkbox clicked add child.setOnClickListener(null).
