我正在尝试使用 Sherlock 操作栏实现 SearchView。我无法让查询进入 onQueryTextChange 方法。不知道出了什么问题。
public class MainActivity extends SherlockFragmentActivity implements
SearchView.OnQueryTextListener {
protected static CharSequence[] _categories = { "Amusement Park",
"Bird Sanctuary", "Wild Life", "River", "Hill Station", "Temple" };
protected static boolean[] _selections = new boolean[_categories.length];
private final String[] places = new String[] { "Mysore", "Bangalore",
"Mangalore", "Wayanad", "Bandipur National Park", "Chickmaglur",
"Bandipura", "Coorg", "Kodaikanal", "Hampi", "Ghati Subramanya",
"Mekedatu", "Muththathhi", "Shivasamudram", "Talakadu",
"Savana Durga" };
public SearchView mSearchView;
private TextView mStatusView;
private Menu mainMenu = null;
PlacesListAdapter adapter;
ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i("Nomad", "onCreate");
List<Place> thePlaces = new ArrayList<Place>();
for (int i = 0; i < places.length; i++) {
Place pl = new Place("NO_ID", places[i], "NO_DISTANCE",
"NO_CATEGORYICON");
thePlaces.add(pl);
}
listView = (ListView) findViewById(R.id.place_list);
adapter = new PlacesListAdapter(MainActivity.this, R.layout.item_place,
thePlaces);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "Test", Toast.LENGTH_SHORT);
startActivity(new Intent(MainActivity.this, PlaceActivity.class));
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
Log.i("Nomad", "onCreateOptionsMenu");
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.activity_main, menu);
mainMenu = menu;
MenuItem searchItem = menu.findItem(R.id.action_search);
// Search View
mSearchView = (SearchView) searchItem.getActionView();
setupSearchView(searchItem);
mSearchView.setOnSearchClickListener(new View.OnClickListener() {
