android - 在 searchView 中设置查询

Question

我想在 Android 应用程序的 searchView 中设置文本。 setQuery 不起作用。

这是我的代码:

 private SearchView searchPostalDelivery;
        private PostalDeliveriesAdapter listAdapter;
        private ExpandableListView myList;

        private ArrayList<PostalDeliveries> postalDeliveryList = new ArrayList<PostalDeliveries>();

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_tab_single_delivery);

            SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
            searchPostalDelivery = (SearchView) findViewById(R.id.searchPostalDelivery);
            searchPostalDelivery.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            searchPostalDelivery.setIconifiedByDefault(false);
            searchPostalDelivery.setOnQueryTextListener(this);
            searchPostalDelivery.setOnCloseListener(this);


             searchPostalDelivery.setQuery("test", false);



        }

解决方法如下:

final String query = getIntent().getStringExtra(SearchManager.QUERY);

    if(!TextUtils.isEmpty(query) && mSearchView != null){

        mSearchView.post(new Runnable() {
            @Override
            public void run() {

                MenuItemCompat.expandActionView(mSearchItem);
                mSearchView.setQuery(query, true);
            }
        });
    }
