SearchWidget不调用onSearchRequested()

我通过searchwidget和listview获得了一个活动。如果有人搜索,则当然应删除与查询不匹配的所有项目。所以我想删除列表中的所有项目,并用较小的列表填充它。所以我尝试将我的ArrayList传递给新的可搜索Activity,方法是将它添加到onSearchRequested方法的Bundle中。但是当我执行搜索时,不会调用此方法。

这是我得到的代码:

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

    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) findViewById(R.id.sv_sign_search_name);
    searchView.setSearchableInfo(searchManager
            .getSearchableInfo(getComponentName()));
    searchView.setIconifiedByDefault(false);
    searchView.setFocusable(false);
    // Get the intent, verify the action and get the query
    Intent intent = getIntent();

    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        Bundle bundle = intent.getBundleExtra(SearchManager.APP_DATA);
        player = bundle.getParcelableArrayList("players");
        player = searchPlayers(query);
        showPlayers();
    } else {
        initializeScreen();
    }
}


@Override
public boolean onSearchRequested() {
     Bundle appData = new Bundle();
     appData.putParcelableArrayList("players", player);
     startSearch(null, false, appData, false);
     return true;
 }

答案 0 :(得分:0)

您需要在Manifest中指定元数据以进行可搜索的活动设置。例如:

<activity android:name=".activity.SuperDuperActivity">
     <meta-data
          android:name="android.app.default_searchable"
          android:value=".activity.SearchResultsActivity"/>
</activity>

然后在您的 SuperDuperActivity 中肯定会调用onSearchRequested()。
