Cancelling an already open toast in Android

Question

I'm currently starting to develop Android applications and I've been following up a this tutorial on how to use and improve the Google maps application. I've managed to show up on screen the map, on touch I get the address of a location (via Reverse Geocoding) with the showing of a `Toast`. But here is my problem - when you click a number of consecutive times over the map you will get all the `toasts` one after other and each of them will take his time (in my case - `Toast.LENGTH_LONG`) to disappear. I want to make the application automatically close the older toast and show a new toast with the new address clicked. In other resources I found I should use the `toast.cancel()` method for this purpose, but I experience trouble using it - I have already overrided the `onTouchEvent` - how can I detect there is a new touch over the map while the `toast` is showing? Or maybe you would suggest me a better way of hiding the already open `toast`? I've tried to make my `Toast` address a global…

Accepted Answer

You don't show where you have `Toast address` as a global, but you are creating a new, local Toast object each time you click with:

```
Toast address;
address = Toast.makeText(getBaseContext(), add, Toast.LENGTH_LONG);
address.show();
```

Which will override the global object you are creating. I'd recommend having `address` as a `private static` object in your class to ensure that address will always be the same object no matter how many times you click so that you are always cancelling the `Toast` that you last showed (since there is only ever one), and remove the local declaration:

```
private static Toast address;
```

...

```
if (address != null)
    address.cancel();

address = Toast.makeText(getBaseContext(), add, Toast.LENGTH_LONG);
address.show();
```
