Every thing in oncreate or create global edittext and TextView

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
 EditText Username = (EditText) findViewById(R.id.EmployerNameEdit);

String userName = Username.getText().toString();
TextView changedName = (TextView) findViewById(R.id.employerName);
changedName.setText(userName);


 }

Answer 2

might be you missed curly bracket,

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    EditText Username = (EditText) findViewById(R.id.EmployerNameEdit);

    String userName = Username.getText().toString();
    TextView changedName = (TextView) findViewById(R.id.employerName);
    changedName.setText(userName);
}

}

if you still getting problem, please fell free to ask question. :)
