SearchView
的操作栏。我查看了谷歌的示例,但无法使其正常工作。我一定是做错了什么,现在感到有些放弃应用程序开发:D 我进行了搜索,但没有找到任何有用的信息。也许你们可以帮帮我:)问题:我已经成功打开搜索视图,但之后什么都没发生。我注意到我的searchManager.getSearchableInfo(getComponentName())返回null。此外,我提供的提示未显示在搜索框中,这让我认为也许应用程序找不到我的searchable.xml?话不多说 :)

@Override

getMenuInflater().inflate(R.menu.activity_main, menu);
// Get the SearchView and set the searchable configuration
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.menu_search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
