How to display Toast in Android?

In order to display Toast in your application, try this:

Toast.makeText(getActivity(), (String)data.result, 
   Toast.LENGTH_LONG).show();

Another example:

Toast.makeText(getActivity(), "This is my Toast message!",
   Toast.LENGTH_LONG).show();

We can define two constants for duration:

int LENGTH_LONG Show the view or text notification for a long period of time.

int LENGTH_SHORT Show the view or text notification for a short period of time.

Customizing your toast

LayoutInflater myInflater = LayoutInflater.from(this);
View view = myInflater.inflate(R.layout.your_custom_layout, null);
Toast mytoast = new Toast(this);
mytoast.setView(view);
mytoast.setDuration(Toast.LENGTH_LONG);
mytoast.show();
