I've implemented a Search Interface (the Search Widget) by following the official tutorial for Search Interface closely. It all looks good but I can't submit the search query. When I click the "Send" button on the keyboard nothing happens.
Here is what I did:
AndroidManifest.xml

public class SearchResultsActivity extends Activity { // more efficient than HashMap for mapping integers to objects SparseArray<Group> groups = new SparseArray<Group>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_search_result); handleIntent(getIntent()); } @Override protected void onNewIntent(Intent intent) { setIntent(intent); handleIntent(intent); } @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_result, menu); return true; } private void handleIntent(Intent intent) { if (Intent.ACTION_SEARCH.equals(intent.getAction())) { String query = intent.getStringExtra(SearchManager.QUERY); // use the query to search your data somehow createData(); ExpandableListView listView = (ExpandableListView) findViewById(R.id.listView); SearchresultExpandableListAdapter adapter = new SearchresultExpandableListAdapter(this, groups); listView.setAdapter(adapter); for (int i = 0; i < groups.size(); i++) { listView.expandGroup(i, false); } } } public void createData() { for (int j = 0; j < 5; j++) { Group group = new Group("Test " + j); for (int i = 0; i < 5; i++) { group.children.add("Sub Item" + i); } groups.append(j, group); } } } I've gone through the code so many times by now. I just don't see the bug. What am I doing wrong?
Thanks for any help.
