Answer 1

I got the solution for the issue. I have introduced a dialogList() in which I am working with a ArrayList. Below I have mentioned the code of my Adapter class.

public class AppListAdapter extends BaseAdapter {

    private LayoutInflater mInflater;
    private List mApps = Constants.list;
    private Context _activity;
    ArrayList months=null;
    ArrayAdapter dataAdapter =null;
    int spinerposition;
    Context contextfordatabase=null;

    int temp=0;
    private int screenWidth;


    /**
     * Constructor.
     * 
     * @param context the application context which is needed for the layout inflater
     * @param screenWidth 
     */
    public AppListAdapter(Context context, int screenWidth) {
        contextfordatabase=context;
        // Cache the LayoutInflate to avoid asking for a new one each time.
        mInflater = LayoutInflater.from(context);
        this._activity=context;
        this.screenWidth = screenWidth;

        months = new ArrayList();
        months.add("No Item Selected");
        months.add("None");
        months.add("Entertainment");
        months.add("Games");
        months.add("News/Books");
        months.add("Social Networking");
        months.add("Utilities");
        months.add("Texting");
        months.add("Web Browsers");
    }

    public int getCount() {

        return mApps.size();
    }

    public Object getItem(int position) {
        return mApps.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public class AppViewHolder {

        private TextView mTitle = null;
        private TextView apptitleTxt = null;
        private TextView offTxt = null;
        private Spinner spiner=null;
        public TextView offtext;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {

        final AppViewHolder holder;
        if(convertView == null) {
            convertView = mInflater.inflate(R.layout.row, null);
            // creates a ViewHolder and stores a reference to the children view we want to bind data to
            holder = new AppViewHolder();

            holder.spiner=(Spinner)convertView.findViewById(R.id.spinner);
            holder.offtext=(TextView)convertView.findViewById(R.id.off_txt);

            holder.apptitleTxt = (TextView) convertView.findViewById(R.id.apptitle_txt);
            Typeface typeface = Typeface.createFromAsset(_activity.getAssets(),"CHICM___.TTF");
            holder.apptitleTxt.setTypeface(typeface);
            holder.offtext.setTypeface(typeface);

            if(screenWidth>480){
                holder.offtext.setTextSize(30);
                holder.apptitleTxt.setTextSize(30);
            }
            convertView.setTag(holder);
        } else { 
            holder = (AppViewHolder) convertView.getTag();
        }

        holder.offtext.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                dialogList(holder.offtext, position);
            }
        });

        holder.apptitleTxt.setText(mApps.get(position).getTitle());
        holder.offtext.setText(mApps.get(position).getVersionName());

        return convertView; 
    }

    /**
     * Sets the list of apps to be displayed.
     * 
     * @param list the list of apps to be displayed
     */
    public void setListItems(List list) { 
        mApps = list; 
    }

    public void dialogList(final TextView textView, final int clickedPosition){
        Builder builder = new AlertDialog.Builder(_activity);
        builder.setTitle("Select Category");
        builder.setItems(R.array.category_list, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) 
            {
                textView.setText(months.get(which+1));
                App app = new App();
                app.setTitle(mApps.get(clickedPosition).getTitle());
                app.setPackageName(mApps.get(clickedPosition).getPackageName());
                app.setVersionName(months.get(which+1));

                mApps.set(clickedPosition, app);
                System.out.println(clickedPosition+" : "+months.get(which+1));


                update_database(mApps.get(clickedPosition).getPackageName(),months.get(which+1));


                AppListAdapter.this.notifyDataSetChanged();
            }

        });
        builder.create();
        builder.show();
    }

    public void update_database(String packageName, String string) {
        CallBackDatabase callback = new CallBackDatabase(contextfordatabase);
        callback.open();
        Cursor cursor =callback.getAll(packageName);
        int y=cursor.getCount();
        int j=0;
        if(y!=0)
        {
            callback.UpdateCategory(packageName, string);
        }
        else
        {
            callback.InsertAppInfo(null, packageName, "0", "0", "0", "null", string);
        }
        cursor.deactivate();
        cursor.close();
        callback.close();
    }
