Android EditText imeOptions making the actionSearch act like actionDone?

I have a weird bug.

I have an EditText, and I'm performing a search with a TextWatcher, when I type 3 letters and above I am performing a search.

Until recently I had a normal EditText, and I want to have a Search Icon in my keyboard so I added my EditText in code:

searchField.setImeOptions(EditorInfo.IME_ACTION_SEARCH);

now it has the search icon, now to my problem. when pressing the Search Icon, all I want to do is close my keyboard. no search required.

here's my code :

searchField.setOnEditorActionListener(new TextView.OnEditorActionListener() {
                @Override
                public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                    if (event != null&& (event.getKeyCode() == KeyEvent.KEYCODE_SEARCH)) {
                        hideSoftKeyboard();
                    }
                    return false;
                }
            });

hideSoftKeyboard is a method that close my keyboard, and that's the code inside:

public void hideSoftKeyboard() {
    if (getActivity().getCurrentFocus() != null) {
        InputMethodManager inputMethodManager = (InputMethodManager) getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
    }
}

NOW, my keyboard DOES close, but for some reason, a "normal" keyboard appears behind it. the keyboard with the search icon is closing, but a keyboard with an enter icon appears, and it's not typing anything.. not connected to any edit text or something, i only have 1 edit text in that screen and I can't figure out what's wrong.

if I change back to IME_ACTION_DONE everything works fine again.

EDIT 1 :

my activity in the manifest :

<activity
        android:name=".UI.activity.HomeActivity"
        android:label="@string/app_name"
        android:launchMode="singleTask"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Holo.Light.NoActionBar"
        android:windowSoftInputMode="adjustResize" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

and my EditText in the xml :

<EditText
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:id="@+id/search_document_main"
                    android:typeface="serif"
                    android:visibility="invisible"
                    android:singleLine="true"
                    android:background="@color/top_bar_bg_color"
                    android:hint="Search" />

any idea what i'm doing wrong?

also, is there a way I can show that Search icon without using the imeOption Search??

Solution

try to get the window token from the EditText window. maybe your current focus item is not the EditText

public void hideSoftKeyboard() {
    InputMethodManager imm = (InputMethodManager) getSystemService(
            Context.INPUT_METHOD_SERVICE
    );
    imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
}

Also you can simplify your listener to:

new TextView.OnEditorActionListener() {
                @Override
                public boolean onEditorAction (TextView v, int actionId, KeyEvent event) {
                    if (actionId == EditorInfo.IME_ACTION_SEARCH) {
                        hideKeyboard();
                        return true;
                    }
                    return false;
                }
            }

If you still have problem please add your Activity layout and also add the Activity manifest declaration
