myMaterDialog.setPositiveButton(positive, new View.OnClickListener() {@Overridepublic void onClick(View v) {myMaterDialog.dismiss();}});myMaterDialog.setNegativeButton(negative, new View.OnClickListener() {@Overridepublic void onClick(View v) {myMaterDialog.dismiss();}});

myMaterDialog.setOnListener(new DialogInterface.OnKeyListener() {@Overridepublic boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {if(keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount()==0){myMaterDialog.dismiss();UserBuyActivity.this.finish();}return false;}});

myMaterDialog.setCanceledOnTouchOutside(false);myMaterDialog.show()
