Answer 1

Please follow this, it shows the cancel button only async and finish will call by clicking on cancel button

protected void onPreExecute() {


        dialogx.setMessage("Loading... Please Wait...");
        dialogx.setCancelable(false);
        dialogx.setButton(DialogInterface.BUTTON_NEGATIVE,
                "Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

                dialogx.dismiss();
                GetDataTask.this.cancel(true);
                finish();
            }
        });
        dialogx.show();
