推荐答案
您检索的活动有做一些事情 - 和实际显示效果
Your Searchable activity has to do something - and actually display results.
我只写了一个作为一个问题，我昨天问<一个建议的答复href="http://stackoverflow.com/questions/4571401/trying-to-filter-a-listview-with-runqueryonbackgroundthread-but-nothing-happens/4571791#4571791">Trying过滤一个ListView与runQueryOnBackgroundThread但没有任何反应？ - 我缺少什么
I just wrote one as suggested by an answer to a question I asked yesterday Trying to filter a ListView with runQueryOnBackgroundThread but nothing happens - what am I missing?
看看这个文件，了解怎样与内置的搜索支持集成：的使用Android的搜索对话框并看一下这篇文章对如何提供建议，客户类型：的添加自定义建议
Look at this documentation for how to integrate with the built in search support: Using the Android Search Dialog and look at this article on how to offer suggestions as the customer types: Adding Custom Suggestions
您的类检索需要得到查询字符串后做多一点。例如，在我的活动中得到的查询字符串，我这样做后：
Your class Searchable needs to do a bit more after getting the query string. For example in my activity after getting the query string I do this:
showResults(query);
和该方法是这样的：
private void showResults(String query) {
// Load the list of countries based on the query
Cursor countryCursor = myDbHelper.getCountryList (query);
startManagingCursor (countryCursor);
// Hook up the query results to the list view
String[] from = new String[] {
WorldInfoDatabaseAdapter.KEY_COUNTRYCODE, WorldInfoDatabaseAdapter.KEY_COUNTRYNAME
};
int[] to = new int[] {
R.id.countryflag, R.id.countryname
};
SimpleCursorAdapter adapter = new SimpleCursorAdapter (this,
R.layout.country_list_row, countryCursor, from, to);
adapter.setViewBinder (new FlagViewBinder ());
myCountryList.setAdapter (adapter);
myCountryList.setOnItemClickListener (new OnItemClickListener () {
@Override
public void onItemClick (AdapterView<?> parent, View view, int position, long id) {
String countryName = myDbHelper.getCountryByID (id);
if (countryName == null) {
new AlertDialog.Builder (SelectCountryActivity.this).setMessage (
"Internal error: Cannot find the country with id'" + id + "'.").show ();
return;
}
// Package up the country name to return
Intent newCountryIntent = new Intent (myCountryList.getContext (), WorldInfoActivity.class);
newCountryIntent.putExtra (WorldInfoActivity.KEY_SELECTED_COUNTRY, countryName);
startActivity (newCountryIntent);
startActivity (newCountryIntent);
finish ();
}
});
}
会员myDbHelper查询我的数据库已经传入的查询字符串国家和列表的形式显示。我的活动都有一个布局，看起来是这样的：
The member myDbHelper queries my database for countries that have the passed in query string and displays them in a list. My activity has a layout that looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
style="?pageBackground">
<TextView
android:id="@+id/selectdlgtitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/select_country_title"
style="?dlgTitle" />
<ListView
android:id="@+id/countrylist"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:cacheColorHint="#00000000"
android:padding="2px"/>
</LinearLayout>
您也许可以做无 setViewBinder 电话 - 我需要因为我翻译这个国家code字段成一个标志图标
You can probably do without the setViewBinder call - I need that because I am translating the country code field into a flag icon.
