Step #7: Add an "Add" Menu Option.................................................

We have most of the logic in place to edit existing restaurants. However, we

still need to add a menu item for adding a new restaurant.

To do this, change LunchList/res/menu/option.xml to replace the existing

options with one for add:

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@+id/add"

android:title="Add"

android:icon="@drawable/ic_menu_add"

/>

</menu>

Note that the add menu item references an icon supplied by Android. You

can find a copy of this icon in your Android SDK. Go to the directory where

you installed the SDK, and go into the platforms/ directory inside of it.

Then, go into the directory for some version of Android (e.g., android-8/),

and into data/res/drawable-mdpi/. You will find ic_menu_add.png in there.

Now that we have the menu option, we need to adjust our menu handling

to match. Restore our older implementation of onCreateOptionMenu() to

LunchList:

public boolean onCreateOptionsMenu(Menu menu) {

new MenuInflater(this).inflate(R.menu.option, menu);

return(super.onCreateOptionsMenu(menu));

}

Then, add an onOptionsItemSelected() implementation in LunchList with the

following:

public boolean onOptionsItemSelected(MenuItem item) {

if (item.getItemId()==R.id.add) {

startActivity(new Intent(LunchList.this, DetailForm.class));
