}

private View.OnClickListener onSave=new View.OnClickListener() {

public void onClick(View v) {

String type=null;

switch (types.getCheckedRadioButtonId()) {

case R.id.sit_down:

type="sit_down";

break;

case R.id.take_out:

type="take_out";

break;

case R.id.delivery:

type="delivery";

break;

}

if (restaurantId==null) {

helper.insert(name.getText().toString(),

address.getText().toString(), type,

notes.getText().toString());

}

else {

helper.update(restaurantId, name.getText().toString(),

address.getText().toString(), type,

notes.getText().toString());

}

finish();

}

};

}

needed by DetailForm:

package apt.tutorial;

import android.content.Context;

import android.content.ContentValues;

import android.database.Cursor;

import android.database.SQLException;

import android.database.sqlite.SQLiteOpenHelper;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteQueryBuilder;

class RestaurantHelper extends SQLiteOpenHelper {

private static final String DATABASE_NAME="lunchlist.db";

private static final int SCHEMA_VERSION= 1 ;

public RestaurantHelper(Context context) {
