将ActionBar搜索查询传递给片段 [英] Pass ActionBar search query to fragment

问题描述

在这里可以看到我有一个SHERLOCK FRAGMENT ACTIVITY，其中包含四个FRAGMENTS和一个SEARCH VIEW.有4个片段，其中最后一个是FRAGMENT SEARCH RESULTS

Here is the seen I have a SHERLOCK FRAGMENT ACTIVITY which holds four FRAGMENTS and a SEARCH VIEW. There are 4 fragments in which last is FRAGMENT SEARCH RESULTS

我的问题是如何将搜索查询的数据从搜索视图传递到FRAGMENT SEARCH RESULTS并在FRAGMENT SEARCH RESULTS

My question is how to pass data of search query to FRAGMENT SEARCH RESULTS from search view and display search result in FRAGMENT SEARCH RESULTS

我实现了

private void setupSearchView(MenuItem searchItem) {
        if (isAlwaysExpanded()) {
            mSearchView.setIconifiedByDefault(false);
        } else {
            searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
        }
        mSearchView.setOnQueryTextListener(this);
    }

    public boolean onClose() {
        return false;
    }

    protected boolean isAlwaysExpanded() {
        return false;
    }

    @Override
    public boolean onQueryTextSubmit(String query) {
        if (query.length() > 0) {
            **//WHAT SHOULD I WRITE HERE**
        }
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        return false;
    }

推荐答案

@Override
    public boolean onQueryTextSubmit(String query) {
        if (query.length() > 0) {
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            Fragment newFragment = new SearchFragment(); //your search fragment
            Bundle args = new Bundle();
            args.putString("query_string", query);
            newFragment.setArguments(args);

            transaction.replace(R.id.content_frame, newFragment);
            transaction.addToBackStack(null);
            transaction.commit();   
        }
        return false;
    }
