How to close Android Soft KeyBoard programmatically?

I have tested and this is working:

...
//to show soft keyboard
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

//to hide it, call the method again
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

By the way, the second parameter of your code is not right, please have a look at here.

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(EditTextName.getWindowToken(), 0);
