can't solve this

i know how to write getter for TextView but i don't know how to use the TextView method to 'set' the 'text' of mTypeLabel' to the type from 'mSpaceship'

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");

}
  public TextView getText() {  
        return mTypeLabel;
    }
}
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;
    }
}

Part 2 of challenge:

Now that we have a model object, update the TextView to use the Spaceship's type property. Remember to use the helpful getter method!

They want us to set the text of the textView while using the getter method. Without knowing much else, we can at least piece together the getter.

mSpaceship.getType()

But this never answered the 'update the TextView' part. They are really just telling you to set the text.

nameOfTextView.setText();

I will let you piece this together.

can u write the code plz...thank u
