android - SearchView 语音识别器不转录文本

Question

我设置了一个简单的 Android 项目，其中一个 Activity 包含启用了语音搜索的 SearchView。当我使用语音搜索功能时，内置语音识别器按预期显示，但它不会在识别器对话框或 SearchView 小部件本身中转录语音文本。但是，它确实通过 SEARCH Intent 正确发送了语音文本，因此可以执行搜索。这是我的项目的源代码和 XML:

AndroidManifest.xml

    return true;

@Override

    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {

        String query = intent.getStringExtra(SearchManager.QUERY);
        doSearch(query);
    }

private void setupSearchView() {
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    final SearchView searchView = (SearchView) findViewById(R.id.dealSearch);
    SearchableInfo searchableInfo = searchManager.getSearchableInfo(getComponentName());
    searchView.setSearchableInfo(searchableInfo);
    searchView.setIconifiedByDefault(false);
}

private void doSearch(String query) {

    Toast.makeText(this, "Searching for: " + query, Toast.LENGTH_LONG).show();

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

    Toast.makeText(this, "Selected item: " + position, Toast.LENGTH_LONG).show();
}
}

请阅读以下注意事项:

Note: Carefully consider whether voice search is appropriate for your application. All searches performed with the voice search button are immediately sent to your searchable activity without a chance for the user to review the transcribed query. Sufficiently test the voice recognition and ensure that it understands the types of queries that the user might submit inside your application.
