I keep running into this problem in my code and I don't know what it means. What am I doing wrong? Thanks!

import android.widget.Button;
import android.widget.EditText;
public class LandingActivity extends Activity {
public Button mThrustButton;
public TextView mTypeLabel;
public EditText mPassengersField;
public Spaceship mSpaceship;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_landing);
mThrustButton = (Button)findViewById(R.id.thrustButton);
mTypeLabel = (TextView)findViewById(R.id.typeTextView);
mPassengersField = (EditText)findViewById(R.id.passengersEditText);
// Add your code here!
mSpaceship = new Spaceship("FIREFLY");
TextView.setText(mSpaceship.getType());
}
}
public class Spaceship {

I think your error is here:
TextView.setText(mSpaceship.getType());
That shouldn't reference a TextView
directly. It should reference the TextView
instance you've already created. That's called mTypeLabel
. So, change the above line to:
mTypeLabel.setText(mSpaceship.getType());
I hope that both makes sense, and works!
Let me know how you get on.
Steve.
