I am trying to to implement SearchView with Sherlock Action Bar. I am not able to get the query to enter the onQueryTextChange method. Not sure whats going wrong.
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() {
@Override
public void onClick(View v) {
// hide action item
if (mainMenu != null) {
mainMenu.findItem(R.id.action_category).setVisible(false);
mainMenu.findItem(R.id.action_sort).setVisible(false);
}
}
});
mSearchView.setOnCloseListener(new SearchView.OnCloseListener() {
@Override
public boolean onClose() {
// re-show the action button
if (mainMenu != null) {
mainMenu.findItem(R.id.action_category).setVisible(true);
mainMenu.findItem(R.id.action_sort).setVisible(true);
}
return false;
}
});
Log.i("Nomad", "after setupSearchView()");
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search:
Toast.makeText(this, "Searh", Toast.LENGTH_LONG).show();
Log.i("Nomad", "Click Search");
break;
case R.id.action_category:
showDialog();
break;
case R.id.action_sort_alpha_az:
Toast.makeText(this, "Alpha AZ", Toast.LENGTH_LONG).show();
break;
case R.id.action_sort_alpha_za:
Toast.makeText(this, "Alpha ZA", Toast.LENGTH_LONG).show();
break;
case R.id.action_sort_dist_nf:
Toast.makeText(this, "Dist NF", Toast.LENGTH_LONG).show();
break;
case R.id.action_sort_dist_fn:
Toast.makeText(this, "Dist FN", Toast.LENGTH_LONG).show();
break;
default:
// return super.onOptionsItemSelected(item);
break;
}
return true;
}
private void setupSearchView(MenuItem searchItem) {
mSearchView.setIconifiedByDefault(true);
mSearchView.setOnQueryTextListener(this);
mSearchView.setSubmitButtonEnabled(false);
searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS);
// | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
}
public boolean onQueryTextChange(String newText) {
Log.i("Nomad", "onQueryTextChange");
if (TextUtils.isEmpty(newText)) {
Log.i("Nomad", "onQueryTextChange Empty String");
listView.clearTextFilter();
} else {
Log.i("Nomad", "onQueryTextChange " + newText.toString());
adapter.getFilter().filter(newText.toString());
}
return true;
}
public boolean onQueryTextSubmit(String query) {
Log.i("Nomad", "onQueryTextSubmit");
return false;
}
public boolean onClose() {
Log.i("Nomad", "onClose");
return false;
}
protected boolean isAlwaysExpanded() {
return false;
}
}
解决方案
Add this to your searchCommand :
searchCommand.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
