android - controlling IME show search action instead of enter

Hi I'm trying to override IME action to show search on virtual keyboard. My EditText is in the control that is placed onto the activity.

Here is what I have:

<EditText android:i开发者_如何学Cd="@+id/txtSearch"
    android:textSize="18dp"
    android:textColor="@color/main_text_black"
    android:layout_width="247dp" 
    android:layout_height="fill_parent"
    android:imeOptions="actionSearch"
    android:gravity="center_vertical"
    android:singleLine="true"
    android:background="@null"
    android:layout_alignParentLeft="true"
    android:layout_marginLeft="38px" />

In Code I have this listener set on the EditText:

@Override
public boolean onEditorAction(TextView view, int arg1, KeyEvent arg2) {
    if((arg1 == EditorInfo.IME_ACTION_SEARCH) {
        for(OnSearchListener listener : _listeners) {
            listener.OnSearch(view, getSearchString());
        }
    }
    InputMethodManager imm = 
        (InputMethodManager)_context.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);

    return false;
}

arg1 always comes back as 0 when I press the enter key, which is "unidentified". I also tried different keyboards like sendMessage and none of them work neither. What's going on?

Thank you in advance!

You need to specify android:inputType="text" attribute in xml file.

updated to droid 2.2 and it started working. Horrible bug!
