Non-static method cannot be referenced from a static context

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

LandingActivity.java
import android.os.Bundle;
import android.view.View;
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());
    }
}
Spaceship.java
public class Spaceship {
    private String mType;
    private int mNumPassengers = 0;

    public String getType() {
      return mType;
    }

    public void setType(String type) {
      mType = type;
    }

    public int getNumPassengers() {
      return mNumPassengers;
    }

    public void setNumPassengers(int numPassengers) {
      mNumPassengers = numPassengers;
    }

    public Spaceship() {
      mType = "SHUTTLE";
    }

    public Spaceship(String type) {
      mType = type;
    }
}

Hi Paul,

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.

If that doesn't help - let me know what line the error says the problem exists on.

Steve.

That was very helpful. Thanks!

No problem! :+1:
