Execute search from action bar

Question

I have successfully gotten my action bar to show up right in android. I am now trying to implement the search. I am trying to start small and at least see if I can get the search term before I try and do anything with it.

I followed this tutorial here:

http://developer.android.com/training/search/setup.html

and created a SearchResultsActivity class which looks like this to handle the search.

import android.app.Activity;
import android.app.SearchManager;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;


public class SearchResultsActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        //possible more code
        handleIntent(getIntent());
    }

    @Override
    protected void onNewIntent(Intent intent) {
        //possible more code
        handleIntent(intent);
    }

    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

            //toast error test
            Context context = getApplicationContext();
            CharSequence text = "Hello toast!";
            int duration = Toast.LENGTH_SHORT;

            Toast toast = Toast.makeText(context, query, duration);
            toast.show();

        }
    }

    ///more code

}

I tried to add a toast to see if when I entered text then clicked search if a toast would pop up. Right now no toast shows up.

I am working on a similar project with a search widget in the action bar. This is only compatible with API 11+ so no gingerbread, but it looks nicer. You still have to set up a searchable.xml and add the appropriate meta-data in the manifest. I'm not sure how you are going to implement this, but the code below loads a ListView, then adds the string. The onCreateOptionsMenu() section configures the search widget and filters the ListView based on the imputed text. Hope it helps!

    public class ListOfMathCourses extends ListActivity  {

    ArrayAdapter<String> adapter;
    ListView list;
    String[] math = new String[] {"Pre-Algebra", "Algebra I", "Algebra II", "Geometry", "Calculus"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.startingpoint);
    list = (ListView) findViewById(android.R.id.list);
    adapter = new ArrayAdapter<String>(this, R.layout.listviewrow, math);
    list.setAdapter(adapter);
    getListView().setTextFilterEnabled(true);


    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {        

        getMenuInflater().inflate(R.menu.menu_search, menu);
        //getMenuInflater().inflate(R.menu.action, menu);   

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();

            searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            searchView.setIconifiedByDefault(false);   

        SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() 
        {
            @Override
            public boolean onQueryTextChange(String newText) 
            {
                // this is your adapter that will be filtered
                adapter.getFilter().filter(newText);
                return true;
            }
            @Override
            public boolean onQueryTextSubmit(String query) 
            {
                // this is your adapter that will be filtered
                adapter.getFilter().filter(query);
                return true;
            }
        };
        searchView.setOnQueryTextListener(queryTextListener);

        return super.onCreateOptionsMenu(menu);

    }

}
