SearchView语音识别器不会转录文本

Question

我设置了一个简单的Android项目，其中包含一个包含启用了语音搜索的SearchView的活动。当我使用语音搜索功能时，内置的语音识别器会按预期显示，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，它通过SEARCH意图正确发送语音文本，因此可以执行搜索。这是我的项目的源代码和XML：

的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();
}
}

请阅读以下注释：

  

注意：仔细考虑语音搜索是否适合您的   应用。使用语音搜索按钮执行的所有搜索都是   立即发送到您的搜索活动，没有机会   用户查看转录的查询。充分测试声音   识别并确保它理解查询的类型   用户可以在您的申请中提交。

那么也许您可以在收到意图时自己设置文本并在onQueryTextChange中进行实际搜索。
