Disabling CheckBox in MultiChoiceItems AlertDialog


I have an AlertDialog which it has dynamic items linked to a Cursor from database , it works fine but i wanted to disable user interaction with that because it's an informational dialog , i've disabled my dialog with :

alert.getListView().setEnabled(false);

but the problem is when Items in the list are bigger than the dialog height , because of disabling it's ListView, Scrolling is disabled too and some items doesn't show up, i've tried some links like : Android : How to disable CheckBox in AlertDialog? with no success. i've also tried :

builder.setMultiChoiceItems(mDBAdapter.instance.getName(SupervisorGuid)
                , SyncDBHelper.instance.SentSupervisors(SupervisorGuid),new DialogInterface.OnMultiChoiceClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which,
                            boolean isChecked) {

                            if(isChecked==true)
                            {

                                    ((AlertDialog) dialog).getListView().setItemChecked(which, false);
                            }
                            else
                            {
                                    ((AlertDialog) dialog).getListView().setItemChecked(which, true); 
                            }


                    }});
        AlertDialog alert = builder.create();

Does anybody know a better way to disable the checkboxes without a Custom dialog? Thanks in Advance.


Solution

  • this may give you some idea...

    private void showDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        ArrayList<String> arrayList = new ArrayList<String>();
        ArrayList<Boolean> selectedList = new ArrayList<Boolean>();
        for (int i = 1; i <= 20; i++) {
            arrayList.add("" + i);
            selectedList.add(i % 2 == 0);
        }
        builder.setAdapter(new MyAdapter(arrayList, selectedList), null);
        builder.show();
    }
    
    
     public static class MyAdapter extends BaseAdapter {
    
        private ArrayList<String> arrayList;
        private ArrayList<Boolean> selectedList;
    
        public MyAdapter(ArrayList<String> arrayList,
                ArrayList<Boolean> selectedList) {
            this.arrayList = arrayList;
            this.selectedList = selectedList;
        }
    
        @Override
        public int getCount() {
            return arrayList.size();
        }
    
        @Override
        public Object getItem(int position) {
            return null;
        }
    
        @Override
        public long getItemId(int position) {
            return 0;
        }
    
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            return getView(parent.getContext(), position);
        }
    
        private RelativeLayout getView(Context context, int position) {
            RelativeLayout relativeLayout = new RelativeLayout(context);
            AbsListView.LayoutParams params = new AbsListView.LayoutParams(
                    ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            relativeLayout.setLayoutParams(params);
            TextView textView = new TextView(context);
            textView.setText(arrayList.get(position));
            RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
            layoutParams.addRule(RelativeLayout.CENTER_VERTICAL);
            layoutParams.leftMargin = 30;
            textView.setLayoutParams(layoutParams);
            relativeLayout.addView(textView);
            CheckBox checkBox = new CheckBox(context);
            layoutParams = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
            layoutParams.rightMargin = 30;
            checkBox.setLayoutParams(layoutParams);
            checkBox.setClickable(false);
            if (selectedList != null) {
                checkBox.setChecked(selectedList.get(position));
            }
            relativeLayout.addView(checkBox);
            return relativeLayout;
        }
    
    }
