Create a custom dialog like this

 private void ShowDialog() {
        LayoutInflater layoutInflaterAndroid = LayoutInflater.from(context);
        View mView = layoutInflaterAndroid.inflate(R.layout.you_dialog_layout, null);
        AlertDialog.Builder alertDialogBuilderUserInput = new AlertDialog.Builder(context);
        alertDialogBuilderUserInput.setView(mView);
        final AlertDialog alertDialogAndroid = alertDialogBuilderUserInput.create();
        alertDialogAndroid.show();
        final EditText edt_qty = (EditText) mView.findViewById(R.id.edt_subject);
        Button cvSubmit = (Button) mView.findViewById(R.id.cvSubmit);

        cvSubmit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if(edt_subject.getText().length()==0)
                {
                    edt_qty.requestFocus();
                    edt_qty.setError("You did not enter a quantitiy");

                } else {
                //code
                }

            }
        });
    }

mHolder.txt_lName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ShowDialog();
        }
    });
