I'm working on an application for my A2 Level Computer Science coursework, and have run into an error when attempting to convert an EditText to an integer. I'm creating an application that is intended to help with managing a Scout group, and I am currently working on allowing the user to create a record containing Scout details, and insert it into a database. Here is the line that is apparently erroneous:
emergencyhome=Integer.parseInt(findViewById(R.id.txtEmergencyHomePhone).toString());
And this comes up in the Logcat:

Don't use toString() to get an integer from an EditText.
Here's how you can get an Integer from your EditText:
//Create and initialize your EditText
EditText editText = findViewById(R.id.txtEmergencyHomePhone);
//Get the String that's contained in the EditText
String userInput = editText.getText().toString();
//Convert the String to an Integer
int emergencyHome = Integer.parseInt(userInput);
If you'd like to combine all of this in one single line (like ninjas do), then here's the way to go:
int emergencyHome = Integer.parseInt(((EditText) findViewById(R.id.txtEmergencyHomePhone)).getText().toString());
I hope this helps.. Merry coding!
