Android Soft Keyboard Secret

How to close/hide the Android Soft Keyboard?

Q : 

I'm having an EditText and a Button in my layout. After writing inside the edit field and clicking on the Button, I want to hide the virtual keyboard. I guess there should be a simple, one- or two-liner to make this happen. Where can I find an example of it?

A : 

You can force Android to hide the virtual keyboard using the InputMethodManager, callinghideSoftInputFromWindow, passing in the token of the window containing your edit field.

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

 This will force the keyboard to be hidden in all situations. In some cases you will want to pass inInputMethodManager.HIDE_IMPLICIT_ONLY as the second parameter to ensure you only hide the keyboard when the user didn't explicitly force it to appear (by holding down menu).
