Java classes usually expose readable attributes with a get* method, and writable attributes with a set* method. In the case of a EditText these are:

getText

and

setText

see here and here (they are inherited from TextView)

Note: Scroll around a bit. You will see that they are defined multiple time. With different parameters. Pick the one you need.

A simple example. Let's assume you have a TextView with the id myTextField:

EditText myText = (EditText) this.findViewById(R.id.myTextField);

// Setting the text:
myText.setText( "Hello World!" );

// "Reading" the text (printing it to stdout):
System.out.println( myText.getText() );
