android - Hide Soft keyboard on return key press

Question

I've searched half a dozen other answers on SO, but haven't found one that works. All I'm trying to do is dismiss the soft keyboard when the user presses the enter button. (The equivalent of the insanely easy iOS 'resignKeyboard' call.) In the following code, the onEditorAction method does not get called. I've set up an EditText view in my XML file and the code in my fragment is as follows:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        fragView = inflater.inflate(R.layout.fragment_encrypt2, container, false);
        textField = (EditText) fragView.findViewById(R.id.textField);

        textField.setOnEditorActionListener(new TextView.OnEditorActionListener() {

            @Override
            public boolean onEditorAction(TextView arg0, int actionId,
                                          KeyEvent arg2) {
                // hide the keyboard and search the web when the enter key
                // button is pressed
                if (actionId == EditorInfo.IME_ACTION_GO
                        || actionId == EditorInfo.IME_ACTION_DONE
                        || actionId == EditorInfo.IME_ACTION_NEXT
                        || actionId == EditorInfo.IME_ACTION_SEND
                        || actionId == EditorInfo.IME_ACTION_SEARCH
                        || (arg2.getAction() == KeyEvent.KEYCODE_ENTER)) {
                    InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(textField.getWindowToken(), 0);

                    return true;
                }
                return false;
            }
        });

        // Inflate the layout for this fragment
        return fragView;//inflater.inflate(R.layout.fragment_encrypt2, container, false);
    }

The following is a snippet from the XML file where I define the EditText field. I need EditText to be multiline.

<EditText
            android:id="@+id/textField"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:hint="@string/Encrypted_Text_Hint"
            android:gravity="top"
            android:inputType="textMultiLine"
            android:imeOptions="actionDone"/>

Answer 1

If you don't want multiple line, for you edittext you can just specify a single line. For the edittext and also you can put imeOptions as Done like this:

<EditText 
   android:id="@+id/edittext_done"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:imeOptions="actionDone"
   android:singleLine="true"
   />

I clearly don't know, whether you are trying to achieve this or not.Any way take a look.

EDIT: android:singleLine is deprecated since API 3 due to bad performance, you have to use android:maxLines instead. singleLine will be available because even now some effects are not supported by android:maxLines attribute.
