Hide Soft Keyboard on Done Keypress in Android?

Use android:imeOptions="actionDone", like that:

<EditText
    ...
    android:imeOptions="actionDone" />

Changed the if-statement to if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER) made it working with the xml-attribute android:inputType="phone".

InputMethodManager inputManager = (InputMethodManager)
context.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.toggleSoftInput(0, 0);

with context being your activity.
