Cooking Application

[Jake Jameson]

I'm in the middle of making an Android cooking application and I have ran into some difficulty

The application is available on my Dropbox account, would anyone be able to download it and tell me how to fix the following things

The favourite button does not Toast, there are no error messages or anything, but the toast message "Added to Favourites" does not appear once the button is clicked, also the Favourite button does not stay enabled, once the user backs out of the recipe, the button becomes disabled again, which leads me to my next problem...

...there is a list of favourite recipes, the idea is: once the favourite button is clicked the recipe will be added to the list of favourites, but as the button does not stay enabled there are no favourites so once the user clicks on the favourite list the app crashes, how can I make the button stay enabled??

There is also a list of 'special diets' gluten free etc how can I make it so that gluten free recipes are connected to that list and will appear once gluten free is clicked

And finally would anyone know how to create a calendar similar to that of the google calendar

Any form of help is greatly appreciated

Hi Jake,

Sorry, if you want us to help you with your problem, you'll have to post your code here.

Make sure you don't post *everything*, but only the parts that are relevant.

Hi Stephen, sorry about that, here's the code I have for the Favourite Button and Favourite List

Favourite_Toast.java

public class Favourite_Toast extends Activity {

    private CheckBox chk;

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

        chk = (CheckBox) findViewById(R.id.checkBox);
        chk.setOnClickListener(checkboxClickListener);

    }

    View.OnClickListener checkboxClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            boolean checked = ((CheckBox) view).isChecked();
            if (checked) {
                Toast.makeText(Favourite_Toast.this,"Added to favourites", Toast.LENGTH_LONG).show();
            }
            else {
                Toast.makeText(Favourite_Toast.this,"Removed from favourites", Toast.LENGTH_LONG).show();
            }
        }
    };

}

Place a chicken piece on a cutting board. Lay a plastic wrap over the chicken piece and pound with a mallet to about a 1/4 inch thickness.

Take a chicken piece and place a slice of ham and a slice of cheese (or 2 if you cut the original in half). Roll chicken... making sure you tuck the sides in as much as possible (this prevents the cheese from oozing out too much in the final baking time). You can secure it with a toothpick. I have, as of lately, started to omit this step. But if you are doing this for the first time, it might help to secure it with the toothpicks. Take the chicken roll and dip into the melted butter/oil... make sure all the sides are well coated.\n" +

You can sprinkle some dried herbs of your choice if you like. I sprinkled some dried basil. Place in the refrigerator for at least an hour to ensure that the breadcrumbs stay put on the chicken :). When ready to bake, place each chicken roll on a parchment lined jelly roll pan (this will help with the cleaning later) making sure you don't overcrowd them. Bake in a preheated 375 oven for 15-20 minutes. Place the pan on the top third rack. Don't over cook the chicken. You can easily do this in a toaster oven as well.");
