Landing Activity

Still failing to master this code

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);

       mSpaceship = new Spaceship ("FIREFLY"); 
       mTypeLabel.setText(mSpaceship.getType());
       mSpaceship = String.format(mPassengerField);// Add your code here!
    }
}
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;
    }
}

The code challenge asks to set the mPassengersField to the value of mSpaceship's mNumPassengers variable. The way it's written, it looks like you're trying to take a String and assign it to the Spaceship object, which isn't what it's asking for, and it also doesn't match type. You have a few options for converting an integer into a string:

mPassengersField.setText(String.valueOf(mSpaceship.getNumPassengers()));

or

mPassengersField.setText(Integer.toString(mSpaceship.getNumPassengers()));

Thanks
