Ok everyone knows that to hide a keyboard you need to implement:
InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE); imm.hi
Try to put stateHidden on as your activity windowSoftInputMode value

For example for your Activity:
this.getWindow().setSoftInputMode( WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
