Good sir, try this:
edittext.setFocusableInTouchMode(true);
edittext.requestFocus();Im not sure, but this might be required on some phones (some of the older devices):
finalInputMethodManager inputMethodManager =(InputMethodManager) context
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.showSoftInput(edittext,InputMethodManager.SHOW_IMPLICIT);
