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!
//setup new spaceship
mSpaceship = new Spaceship("FIREFLY");
// Update TextView to use Spaceship's type
mTypeLabel.setText(mSpaceship.getType());
mPassengersField.setText("" + mSpaceship.getNumPassengers());
}
}
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;
}
}
So I think, the number of passengers is already set in the second file so we just need to get them in the first file, like mPassengersField.setText("" + mSpaceship.getNumPassengers());
The speech marks are just there to quickly convert an int to a string.
It passed, so I'm hoping it's right!

5,132 PointsAt the stage as you with this one, I think I'm almost there, the only pop up error Im getting is with mPassengersField requiring a string but getting an int. Of course, as with all of this I could be completely wrong. You found the solution? How to convert from a string to int, brain work...
