Answer 1

the answer is following to my question:

{
        int size=tempArray.length;

        for(int i=0;i<size;i++){
            Items.add(tempArray[i]);
}

and

            if(index==3)
            {
                final Dialog dialog=new Dialog(Starttracker.this);
                dialog.setContentView(R.layout.popup);
                dialog.setTitle("Enter The Item");
                dialog.setCanceledOnTouchOutside(true);

                final EditText filename=(EditText)dialog.findViewById(R.id.filename);
                filename.setText("");

                Button d_ok=(Button)dialog.findViewById(R.id.d_ok);
                Button d_cancel=(Button)dialog.findViewById(R.id.d_cancel);


                d_ok.setOnClickListener(new OnClickListener(){

                    public void onClick(View arg0) {
                        // TODO Auto-generated method stub

                        String textHolder = filename.getText().toString();

                        dialog.dismiss();

                        Items.add(textHolder);

                        //  s1.setAdapter(adapter);

                        // notifyDataSetChanged();

                    }
                });
                d_cancel.setOnTouchListener(new OnTouchListener(){
                    public boolean onTouch(View v,MotionEvent me){
                        dialog.dismiss();
                        return false;
                    }
                });
                dialog.show();

                return;
            }
