Hi, can someone show me what to do here? Thanks!

Time for a quick review! Below we are accessing an EditText and a TextView. We have accessed the actual controls, but lets now set the TextView's contents with whatever is in the EditText.

CodeChallenge.java 
EditText entryField = (EditText)findViewById(R.id.entry_field);
TextView textHolder = (TextView)findViewById(R.id.text_holder);

String text = entryField.getText().toString(); textHolder.setText(text);

What you have to do is First obtain the String from your EditText. After that you have to set the text in your TextView with the string you previously obtained. Here is the code implementation: String text = entryField.getText().toString(); //Obtain the string from EditText and store it in text textHolder.setText(text); //Pass the text to TextView
