If you want to show all content of EditText in one Toast, then just use concatenation

String concatenatedText = str1 + str2 + str3 + ... 

or StringBuilder class:

StringBuilder sb = new StringBuilder();
String concatenatedText = sb.toString();

and simply pass the result as second argument, as below:

Toast toast = Toast.makeText(context, concatenatedText, duration);
