android search with suggestions

Question

I want to make a search with suggestions.

after running the app and typing a string in my search box non of the following Logs Log.d("states","a onCreate"), Log.d("states",arg0.toString()), Log.d("states",query) or Log.d("states","searchactivity onCreate") execute.

What do I have to do do so the query() method in a.java or the onCreate() method in b.java are called?

Please dont send me to google developer documents its very confusing.

MainActivity.java

package com.example.searchapp;


import android.app.ActionBar;
import android.app.Activity;

import android.app.SearchManager;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuInflater;
import android.widget.SearchView;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.d("states","MainActivity onCreate");

        ActionBar actionBar = getActionBar();
        //actionBar.setDisplayShowHomeEnabled(false);
        actionBar.setDisplayShowTitleEnabled(false);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the options menu from XML
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.options_menu, menu);

        // Get the SearchView and set the searchable configuration
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        // Assumes current activity is the searchable activity
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
        //searchView.setSubmitButtonEnabled(true);
        searchView.setQueryRefinementEnabled(true);

        return true;
    }

}

a.java

package com.example.searchapp;

import android.content.ContentProvider;
import android.content.ContentValues;
import android.database.Cursor;
import android.net.Uri;
import android.util.Log;

public class a extends ContentProvider{

    @Override
    public int delete(Uri arg0, String arg1, String[] arg2) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public String getType(Uri arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public Uri insert(Uri arg0, ContentValues arg1) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public boolean onCreate() {
        // TODO Auto-generated method stub
        Log.d("states","a onCreate");
        return true;
    }

    @Override
    public Cursor query(Uri arg0, String[] arg1, String arg2, String[] arg3,
            String arg4) {
        // TODO Auto-generated method stub
        Log.d("states",arg0.toString());
        String query = arg0.getLastPathSegment().toLowerCase();
        Log.d("states",query);
        return null;
    }

    @Override
    public int update(Uri arg0, ContentValues arg1, String arg2, String[] arg3) {
        // TODO Auto-generated method stub
        return 0;
    }

}

b.java

package com.example.searchapp;

import android.app.Activity;
import android.app.SearchManager;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class b extends Activity {


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.d("states","searchactivity onCreate");
        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
          String query = intent.getStringExtra(SearchManager.QUERY);

          Log.d("states",query);

        }
    }

}

I think in your a-class you have to implement the getType()-method:

private UriMatcher uriMatcher; 

@Override
public boolean onCreate() {
   final String authority = "com.example.searchapp.searchsuggestion";
   uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
   uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY, SEARCH_SUGGEST);
   uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY + "/*", SEARCH_SUGGEST);
   return true;
}

@Override
public String getType(Uri uri) {
    switch (uriMatcher.match(uri)) {
        case SEARCH_SUGGEST:
           return SearchManager.SUGGEST_MIME_TYPE;
        default:
           throw new IllegalArgumentException("Unknown URL " + uri);
     }
}
