Photographic Memory

size of the SurfaceView. When the camera button is clicked, we take a

picture, re-enabling the preview in the PhotoCallback.

Step #4: Tie In the Photographer Class............................................

Finally, we need to allow the user to take a picture. Since we (theoretically)

want our photos taken with Photographer to be associated with the

restaurant, we can add an option menu choice to our DetailForm. Here is the

revised LunchList/res/menu/option_detail.xml:

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

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

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

android:title="Call"

android:icon="@drawable/ic_menu_call"

/>

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

android:title="Take a Photo"

android:icon="@drawable/ic_menu_camera"

/>

</menu>

We also need to update onOptionsItemSelected() in DetailForm to watch for

this new menu choice, so modify yours to look like:

@Override

public boolean onOptionsItemSelected(MenuItem item) {

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

String toDial="tel:"+phone.getText().toString();

if (toDial.length()> 4 ) {

startActivity(new Intent(Intent.ACTION_CALL,

Uri.parse(toDial)));

return(true);

}

}

else if (item.getItemId()==R.id.photo) {

startActivity(new Intent(this, Photographer.class));

return(true);

}

return(super.onOptionsItemSelected(item));

}
