Android FragmentActivity与（共享？）两个片段之间的Android.Widget.SearchView？

Question

我有一个包含两个片段的FragmentActivity(support-v4)。并且都包含一个带有ActionBar的SearchView的菜单。

PlayListFragment：

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    Log.d(LOGTAG, String.format("onCreateOptionsMenu(%s,%s)", this, menu));
    inflater.inflate(R.menu.playlist_ab_menu, menu);
    buildLocalSearchView(menu.findItem(R.id.menu_playlist_search));
    super.onCreateOptionsMenu(menu, inflater);
}
private void buildLocalSearchView(MenuItem item) {
    SearchView searchView = (SearchView) item.getActionView();
    searchView.setSubmitButtonEnabled(false);
    searchView.setIconifiedByDefault(true);
    searchView.setIconified(true);
    //don't work because a bug in android, @see https://code.google.com/p/android/issues/detail?id=25758
    searchView.setOnCloseListener(this);
    //workaround for the above
    MenuItemCompat.setOnActionExpandListener(item, new MenuItemCompat.OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            return true;
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            return true;
        }
    });
    searchView.setOnQueryTextListener(adapter);
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    Log.d(LOGTAG, String.format("onCreateOptionsMenu(%s,%s)", this, menu));
    inflater.inflate(R.menu.filterlist_ab_menu, menu);
    // Get the SearchView and set the searchable configuration
    buildLocalSearchView(menu.findItem(R.id.menu_filterlist_search));
    super.onCreateOptionsMenu(menu, inflater);
}

附注。

我找到了原因，但没有解决方法:com.android.internal.widget.ActionBarView.ExpandedActionViewMenuPresenter#CollapseItemActionView

呼叫

    // Do this before detaching the actionview from the hierarchy, in case
    // it needs to dismiss the soft keyboard, etc.
    if (mExpandedActionView instanceof CollapsibleActionView) {
        ((CollapsibleActionView) mExpandedActionView).onActionViewCollapsed();
    }

com.android.internal.view.menu.MenuBuilder#restoreActionViewStates

如何禁用ActionBar/SearchView/TextView的保存和还原？

Answer 1

@Override
public void onDestroyView() {
    super.onDestroyView();
    Log.d(LOGTAG, String.format("onDestroyView(%s)", this));
    searchView.setOnQueryTextListener(null);
    searchView.setQuery("", true);
}

这个就行了。因为所有SearchView都具有相同的TextView，因此从相同的bundle-key保存/还原，所以不可能使用多个SearchView。
