我正在尝试制作搜索栏并搜索列表视图项。 这是行不通的。 问题：当我输入查询并按确定/输入时，我的TrickPage（活动）不会被触发。
我正在开发基于官方教程的搜索小部件界面：
TrickPage（MainActivity）
public class TrickPage extends Activity implements OnQueryTextListener {
ListView listViewArticles;
String address;
String title;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.search_menu, menu);
SearchManager searchManager = (SearchManager) getSystemService( Context.SEARCH_SERVICE );
SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setSubmitButtonEnabled(true);
searchView.setOnQueryTextListener(this);
return super.onCreateOptionsMenu(menu);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_trick);
getActionBar().setDisplayHomeAsUpEnabled(true);
/*
* Data can be from your database. You have to know the number of list
* items in advanced, in our example, we have 9
*/
Folder[] folderData = new Folder[9];
/*
* @always start with index 0
*
* @9 items in our list view.
*/
folderData[0] = new Folder(R.drawable.icon_music_folder, "First Tut", "Trick number 2") ;
folderData[1] = new Folder(R.drawable.icon_pictures_folder,
"Second Tut", "Trick number 2");
folderData[2] = new Folder(R.drawable.icon_spreadsheet_folder,
"Third Tut", "Trick number 3");
folderData[3] = new Folder(R.drawable.icon_music_folder, "FM Static",
"One of my most favorite bands.");
folderData[4] = new Folder(R.drawable.icon_pictures_folder,
"Outing 2012", "Pictures in Boracay Island.");
folderData[5] = new Folder(R.drawable.icon_spreadsheet_folder,
"Business Spreadsheet", "Business accounts record.");
folderData[6] = new Folder(R.drawable.icon_music_folder, "New Artists",
"Cool songs by new artists.");
folderData[7] = new Folder(R.drawable.icon_pictures_folder,
"Anniversary 2012", "Company party.");
folderData[8] = new Folder(R.drawable.icon_spreadsheet_folder,
"Credit Spreadsheet", "Credit records every month.");
// Pass the folderData to our ListView adapter
FolderAdapter adapter = new FolderAdapter(this,R.layout.listview_item_row, folderData);
// Set the adapter to our ListView
listViewArticles = (ListView) findViewById(R.id.listView1);
listViewArticles.setAdapter(adapter);

int position, long id) {

startActivity(newActivity2);;

.toString();
// just toast it

考虑SplashScreen是您希望搜索小部件调用的活动，请将其添加到应用标记内：
<meta-data android:name="android.app.default_searchable"
android:value="com.meygraph.illustratortutorials.SplashScreen" />

我想您在添加适配器后忘记添加此调用：
listViewArticles.setTextFilterEnabled(true);
我希望这可以帮到你;）
