Instead of using some of the deprecated SimpleCursorAdapter constructors, many people have suggested to use LoaderManager and CursorLoader. So when calling getLoaderManager().initLoader() it gives me this error:
The method initLoader(int, Bundle, LoaderManager.LoaderCallbacks) in the type LoaderManager is not applicable for the arguments (int, null, SearchResultsActivity)
I have tried importing the v4 version of the loadermanager and cursorloader, but that has not seem to work. I have also tried the getSupportLoaderManager(), which doesn't work as well. I noticed that some people are getting this error and have looked through the conversation to try and find solutions, but the ones I have found don't work. I am calling the LoaderManager within the showResults() method btw
Code for searchable activity:
import android.os.Bundle;
import android.app.LoaderManager;
import android.app.LoaderManager.LoaderCallbacks;
import android.app.SearchManager;
import android.app.ListActivity;
import android.support.v4.app.FragmentActivity;

import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.SearchView;
import android.widget.SimpleCursorAdapter;
import android.content.Context;
import android.content.Intent;
import android.content.Loader;
import android.database.Cursor;
public class SearchResultsActivity extends FragmentActivity {
private ListView list;
DatabaseTable db;
LoaderManager lm;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_results);
db = new DatabaseTable(this);
handleIntent(getIntent());
}
public void onNewIntent(Intent intent) {
setIntent(intent);
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
showResults(query);
}
}
private void showResults(String query) {
db = new DatabaseTable(this);
Cursor cursor = db.getContactMatches(query, null);
list = (ListView)findViewById(android.R.id.list);
getSupportLoaderManager().initLoader(0, null, this);
SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1,
null, new String[] {DatabaseTable.COL_NAME}, new int[] {android.R.id.text1}, 0);
list.setAdapter(mAdapter);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent contactIntent = new Intent(getApplicationContext(), ContactActivity.class);
contactIntent.setData(getIntent().getData());
startActivity(contactIntent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
// Associate searchable configuration with the SearchView
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.search:
onSearchRequested();
return true;
default:
return false;
}
}
}
The method
initLoader(int, Bundle, LoaderManager.LoaderCallbacks)
in the type LoaderManager is not applicable for the arguments(int, null, SearchResultsActivity)
Simply put: SearchResultsActivity
must implement LoaderManager.LoaderCallbacks
. Otherwise this
doesn't refer to an instance of LoaderManager.LoaderCallbacks
