     dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;

Simply you can pass your EditText object to this method and inside the OnitemClickListener you can set text to the EditText using the values from your Arraylist.

public static void amount_dialog(final Activity activity,String str,EditText edittextObject)
{
     amount=str;

     sequence_number();//from this method am generating list and setting it into my Arraylist

     dialog=new  Dialog(activity,R.style.CustomDialogTheme);    

     dialog.setContentView(R.layout.customdialog);

     ListView listView=(ListView) dialog.findViewById(R.id.listView12);              
     adapter=new ArrayAdapter<String>(activity,R.layout.list2,R.id.list_text1, strings);
     listView.setAdapter(adapter);  
     listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            selected_amount=adapter.getItem(arg2);
             edittextObject.setText("get the value from arraylist here");
            dialog.dismiss();


        }
    });


     dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;

     dialog.show();
     dialog.setCanceledOnTouchOutside(true);


}

I assume that the activity you pass as a parameter is the activity containing your EditText. So you can do something like this:

EditText editText = (EditText)activity.findViewById(theIDofYourTextEdit);
editText.setText(selectedAmount);

inside your onItemClick-method.

I hope this helps
